Abstract:
A methodological approach to determine the optimum time to control weeds that integrates aspects of weed biology, weed-crop competition, and economics is presented. The approach is based on the concept of Time Density Equivalent: this is defined as the density of weed plants that germinate with the crop and compete until harvest that causes the same yield loss caused by a group of weeds with a given density, time of emergence, and time of removal. A model was developed that accounts for pattern of weed emergence and permits determination of timing of weed control that minimizes economic loss due to weeds emerging both before and after treatments. The outcomes of the model are presented with two examples: corn in competition with velvetleaf and soybean in competition withAmaranthus cruentus.For both crops, six different weed control strategies involving preemergence, chemical, and mechanical postemergence treatments are considered. The results obtained with the model are compared with the calculation of net margin based on assumptions of simultaneous emergence of crop and weeds and no effect of different times of control. Different control strategies are compared considering not only maximum net margin but also its dependence on time of control, because a strategy with a lower value of maximum net margin, but a flatter net margin curve, allows more flexibility of time of control.

Abstract:
Weed control in vineyards is essential to allow optimal vines development. In this study, three different techniques (hoeing, chemical control, and mulching) used in vineyard’s under-row weed control were compared considering their: operative and economic aspects, energy consumptions and environmental impacts. Trials were performed in a vineyard located in Canelli (AT), Italy, characterized by 3 different gradient slopes (<5%, 10-15%, >20%). Each technique has been tested in 3 adjacent rows per each of the 3 vineyard slopes (randomized block test). Two weed control treatments were performed (at 50 days interval) during the peak vegetation growth period (from mid-April to mid-August). Major families of weeds in the test rows were described and scored (%), and weed control efficiency was measured by comparing the weeds cover area projected to the ground vs the test area. Results highlights that the use of mulching machine and the boom sprayer permits to maintain a weed coverage lower than 30% independently of slope gradient. The hoeing, characterized by low operational costs (26 € h–1) and energy requirement (550 MJ ha–1), scored acceptable working performances, but, in case of heavy rains, it can cause a runoff of the soil. The chemical weed control, also if results a valid choice in term of work quality, is not a valid solution from the environmental point of view. The mulching machine, although shows higher operating costs compared to other machines tested (30 € h–1), can be considered as the most viable alternative to chemical weed control because its working efficiency is comparable to that obtained by the sprayer.

Abstract:
There are three primary activities that characterize the discipline of Weed Science. These activities are weed technology, weed biology, and the ethics of weed control. Each of these activities needs to be considered as herbicide-tolerant crops (HTCs) are introduced. HTCs are the most recent refinement in the existing technology to control weeds. The potential benefits from the improved weed control must be weighed against possible increased costs of production and potential for genes that control herbicide tolerance to escape into non-tolerant plant populations. These questions about herbicide resistance are primarily technological and biological. They demonstrate the paucity of information in Weed Science on weed genetics, gene flow, fitness, and other aspects of weed-crop population dynamics. Other questions about HTCs are ethical. They require that we ask who benefits from the technology and what are the economic, ecological, and social consequences of it.

Abstract:
Cultural practices, such as delayed crop seeding, tillage, black fallow, crop rotation, hand weeding, and competitive crops, when used to replace herbicides, provide an opportunity to reduce the selection pressure that causes weeds to become resistant to herbicides. Herbicides on the other hand reduce the selection pressure that causes weeds to resist cultural practices. Rotation of the two systems should then delay resistance to both systems. Growers consider many factors in addition to weed resistance in selecting herbicide or cultural weed control, from associated convenience to economic potential. Rotation of different types of weed control practices would delay resistance, compared to a continuous single practice. The extent of the delay depends upon genetics of resistance, weed reproduction characteristics, weed seed survival, and fitness of resistant weed plants. An understanding of the basic aspects of weeds and herbicides, as well as their interaction with the environment, would help in predicting the delay in resistance to an herbicide from use of cultural practices in the rotation. A grower's final choice of a weed control practice will involve available equipment, time, markets, and soil erosion in addition to potential weed resistance. Weeds that develop resistance to a control practice still allow for reversion to preresistance practices, an important component of a grower's decision. The rate of resistance development is dependent upon the removal of susceptible genes from the population and fitness of the resistant plants. Resistance might be delayed for many years or be manageable when the resistance is genetically recessive or resistant weeds are poorly fit. Growers may not want to accept alternative cultural practices as long as there is the potential for development of another herbicide or reversion to cultural control after resistance occurs.

Abstract:
Sorghum halepense (L.) Pers is a common and noxious worldwide weed of increasing distribution in many European countries. In the present review, information on the biology, ecology, agricultural, economic and environmental impact of johnsongrass is given, and the current status of this weed in Europe is discussed. Furthermore, special attention is given to the important role of field trials using glyphosate to control weeds in arable and perennial crops in many European countries. Some of the factors which affect control efficacy and should be taken into account are also discussed. Finally, several non-chemical alternative methods (cultural, mechanical, thermal, biological, etc.) for johnsongrass management are also presented. The adoption of integrated weed management (IWM) techniques such as glyphosate use, crop rotation, and deep tillage is strongly recommended to control plant species that originate from both seed and rhizomes.

Abstract:
Current awareness about the environmental impact of intensive agriculture, mainly pesticides and herbicides, has driven the research community and the government institutions to program and develop new eco-friendly agronomic practices for pest control. In this scenario, integrated pest management and integrated weed management (IWM) have become mandatory. Weeds are commonly recognized as the most important biotic factor affecting crop production, especially in organic farming and low-input agriculture. In herbaceous field crops, comprising a wide diversity of plant species playing a significant economic importance, a compendium of the specific IWM systems is missing, that, on the contrary, have been developed for single species. The main goal of this review is to fill such gap by discussing the general principles and basic aspects of IWM to develop the most appropriate strategy for herbaceous field crops. In particular, a 4-step approach is proposed: (i) prevention, based on the management of the soil seedbank and the improvement of the crop competitiveness against weeds, (ii) weed mapping, aiming at knowing the biological and ecological characteristics of weeds present in the field, (iii) the decision-making process on the basis of the critical period of weed control and weed thresholds and iv) direct control (mechanical, physical, biological and chemical). Moreover, the last paragraph discusses and suggests possible integrations of allelopathic mechanisms in IWM systems.

Abstract:
Plant invasions of natural systems threaten biodiversity and ecosystem processes across many biomes. Historically most plant invasions have been facilitated by human activities such as industry, transport and landscape modification. Consequently, both causes and management of weed invasion are dependent on human behaviour and management advice provided by ecologists needs to take account of this fact. This paper assesses current environmental weed control policy in Australia and asks: are government, land managers and the scientific community using available social levers to achieve optimal weed management? We do this by comparing aspects of weed policy with a generalized natural resource policy framework. Adequacy of issue characterization and policy framing are discussed with particular reference to public perceptions of the weed problem, policy scaling and defining policy principles and goals. The implementation of policy Instruments, including regulation, VOluntary incentives, education, Information, motivational instruments, property-right instruments and pricing mechanisms are reviewed. Limitations of current instruments and potential options to improve instrument effectiveness are discussed. Funding arrangements for environmental weed control are also reported: environmental weed invasion generally represents an external cost to economic markets which has resulted in relatively low funding levels for control operations. Finally, review and monitoring procedures in weed programmes and policy are addressed. Rigorous monitoring systems are important in effective, adaptive weed management where control techniques are continually refined to improve ecological outcomes. The utility of maintaining links between project outcomes and policy inputs along with methods of implementing appropriate monitoring are discussed.

Abstract:
Controlling herbicide resistance (HR) and its associated environmental risks is impossible without integrating social and economic science with biophysical and technology aspects. Herbicide resistance is a dynamically complex and ill-structured problem involving coupled natural–human systems that defy management approaches based on simple scientific and technology applications. The existence of mobile herbicide resistance and/or herbicide tolerance traits add complexity because susceptibility to the herbicide is a resource open to all farmers, impacting the weed population. Weed scientists have extensively researched the biophysical aspects and grower perceptions of HR. They also recognize that the “tragedy of the commons” can appear when herbicide resistance is mobile across farms. However, the human structures and processes, especially private and public institutions that influence individual and group decisions about HR, have received little analysis. To start filling that gap, we discuss an integrative management approach to sustainable weed control that addresses the social complexity of farm heterogeneity. For example, the need for a private or public collective mechanism becomes apparent to address common-pool resource (CPR) aspects when one farmer's weed control actions influence their neighbors' situations. In such conditions, sole reliance on education, technical assistance, and other incentives aimed at changing individual grower behavior likely will fail to stem the advance of HR. Social science theories can be used to enrich the understanding of human interaction with the biophysical environment and identify key actors and social change processes influencing those interactions in the case of HR. The short-run economic advantages of herbicides such as glyphosate work against social change to address HR, including the development of collective actions when mobile HR conditions exist. We discuss seven design principles that can improve the efficacy and cost of such collective approaches and draw insights from CPR approaches outside of HR.

Abstract:
Field experiments were conducted near Scottsbluff, NE, in 2001 and 2002 to compare economic aspects of glyphosate applied to different glyphosate-resistant sugar beet cultivars with that of conventional herbicide programs applied to near-equivalent, non–glyphosate-resistant conventional cultivars. Glyphosate applied two or three times at 2-wk intervals, beginning when weeds were 10 cm tall, provided excellent weed control, yield, and net economic return regardless of the glyphosate-resistant sugar beet cultivar. All conventional herbicide treatments resulted in similar net economic returns. Although the conventional sugar beet cultivars ‘HM 1640’ and ‘Beta 4546’ responded similarly to herbicide treatments with respect to sucrose content, ‘Beta 4546RR’ produced roots with 1% more sucrose than ‘HM 1640RR’. When averaged over herbicide treatments, a producer planting Beta 4546RR could afford to pay US $185/ha more for glyphosate-resistant technology as could a producer planting HM 1640RR. When averaged over cultivars and herbicide treatments, it is estimated that a producer could afford to pay an additional US $385/ha for glyphosate-resistant technology without decreasing net return.

Abstract:
Moringa oleifera Lam. (moringa hereafter) is cultivated as a new summer super-forage field crop in Israel, yet no weed control protocol has been developed for it. The objective of the study was to develop an integrated weed management (IWM) practice for the moringa agro-system in arid and semi-arid regions like the Mediterranean basin. We tested various herbicides applied pre (PRE) and post (POST) crop emergence and cultivation methods for weed control, with an emphasis on crop safety. The PRE herbicides were the most effective and safe control mean. Their application resulted in minor (<5%) crop fresh weight reductions and weed cover area, compared with the control. The POST herbicides were also effective, yet their crop safety level was lower and non-consistent in some treatments. Generally, the finger weeder was less effective than the herbicide treatments and caused higher fresh weight reduction. However, this means was more effective when applied at earlier stages. Management and environmental conditions had a high impact on the moringa growth; hence, these aspects should be considered. Our results show the potential use of different herbicides and non-chemical tools and set the basis for a future IWM protocol for moringa. The wide range of options offered here can ensure economic and environmentally viable solutions for this new crop.

Abstract:
Cropping systems were: corn + atrazine + EPTC/dichlormid; corn + atrazine + metolachlor; corn + atrazine + bentazon; corn + EPTC/dichlormid intercropped with red clover as green manure or managed as forage crop in the following year; alfalfa + EPTC; soybean + metalachlor + metribuzin; sorghum as green manure followed by winter wheat; and spring barley + diclofop-methyl + bromoxynil. Control treatments were yellow nutsedge growing in a pure stand and complete yellow nutsedge control. After two growing seasons in experiment #1, the tuber population had decreased in all cropping systems. Yellow nutsedge was reduced to 9% of the initial population under perfect control while it tripled in the pure stand. After the first growing season in the second experiment, only corn intercropped with red clover significantly reduced yellow nutsedge population by 17%. When the systems were not treated with herbicides, the yellow nutsedge population increased between 41 to 180% in all cropping systems. There was a significant relation between yellow nutsedge, broadleaf weed and grass densities and yellow nutsedge tuber production. Corn was the most profitable cropping system. The least economically advantageous cropping system was barley.

Abstract:
This study investigates the economic impact of the ARC PPRI Weeds Research Division. The Division researches appropriate methods of biological control for invasive alien plants (IAPs). These plants pose an increasing threat to environmental integrity and ecosystem service provision impacting on economic potential. Since the work of the Division is considered a public good, a predominantly descriptive approach has been adopted for the valuation process. A combination of quantitative cost analysis and a qualitative study of the impacts of research and invasive alien plants is used to deal with the challenges associated with non-market valuation. The study found that investment into the Weeds Division is a valuable activity that supports the long-term growth potential of the South African economy. The role of a well-functioning environment is highlighted as an essential base for the creation of sustained growth opportunities in any society. It was determined that investment into the Division should be increased into the future to support efficient spending of scarce state funds. Biological control research was found to provide strategic future growth potential, creating opportunities for the development of a competitive advantage in the biotechnology and environmental management sectors. The study adds to the increasing move towards a more holistic view of economic valuation, taking factors other than pure finance and econometrics into consideration. This is an important shift in prevailing economic thought, as a realisation is reached that a single, or even triple, bottom line is an outdated and insufficient decision making basis.

Abstract:
Abstract The aim was to determine the association between baseline factors, such as oral health-related behavior, attitudes, knowledge and beliefs in relation to caries increment during a randomized clinical trial (RCT). A further aim was to evaluate treatment costs and health outcomes during and after the RCT. In Pori Finland, 11- to 12-year-old children with active initial caries lesion(s) participated in the RCT in 2001–05. The experimental group (n=250) received multiple measures for controlling caries. The control group (n=247) received standard dental care. In 2005–08, all received standard dental care. Regression analyses were used to study the associations between behavioral factors and caries increment. Cost-effectiveness analysis was conducted (trial period), and costs and health outcomes as well as dental service utilization were evaluated (post-trial period). In the experimental group, brushing teeth twice a day was indicative of developing no new caries lesions, whereas eating candy at least once a day, predicted new lesions. In the experimental and control groups, lack of concern about cavities and lack of knowledge about mother’s dental health predicted new caries lesions. The average incremental cost for averting one DMF surface was €34. The experimental regimen was more effective and more costly than the standard dental care. The total costs decreased year after year. The mean total cost per adolescent was lower and the clinical outcome was better among the former participants in the experimental group. The utilization of dental services was significantly more regular among the former participants in this group. It may be feasible to control caries more effectively by affecting toothbrushing, candy eating and oral health-related attitudes, as preventive procedures may be ineffective if those factors are not in order. It is important to discuss oral health-related topics in families, because this may improve the oral health-related behavior of children. Cost-effectiveness of regimen used for the experimental group may be improved by division of work or by selective reduction of preventive procedures. Well-timed caries control can decrease treatment cost and yield long-term improvement of dental health
Tiivistelmä Tutkimuksen tarkoituksena oli selvittää satunnaistetun kliinisen kokeen alussa rekisteröityjen suunterveyteen liittyvien tapojen, tietojen, asenteiden, uskomusten ja karieskertymän välisiä yhteyksiä. Lisäksi arvioitiin hoitokustannuksia ja hoidollisia tuloksia sekä kokeen ajalta että kokeen jälkeiseltä ajalta. Ne 11–12-vuotiaat lapset, joilla oli ainakin yksi alkava aktiivinen kariesvaurio, osallistuivat kokeeseen Porissa vuosina 2001–05. Koeryhmän lapset (n=250) saivat tehostettua ehkäisevää hoitoa ja kontrolliryhmän lapset (n=247) tavanomaista hammashoitoa. Kaikki saivat tavanomaista hammashoitoa vuosina 2005–08. Käyttäytymisellisten tekijöiden ja karieskertymän välisiä yhteyksiä tutkittiin regressioanalyysien avulla. Kustannusvaikuttavuusanalyysi tehtiin kokeen ajalta. Hoitokustannuksia ja hoidollisia tuloksia sekä palveluiden käyttöä arvioitiin kokeen jälkeiseltä ajalta. Lapsilla, jotka harjasivat vähintään kaksi kertaa päivässä, oli yleensä ehjät hampaat, kun taas lapsilla, jotka söivät päivittäin makeisia, oli useasti reikiä. Huolettomuus reikiintymistä kohtaan ja tietämättömyys äidin hampaiden kunnosta näkyi lasten hampaiden reikiintymisenä. Yhden hammaspinnan säästyminen paikkaukselta maksoi keskimäärin 34 €. Koeryhmän saama hoito oli vaikuttavampaa, mutta kalliimpaa kuin kontrolliryhmän saama hoito. Kokonaiskustannukset laskivat vuosi vuodelta. Keskimääräiset hoitokustannukset olivat pienemmät ja hammasterveys parempi entisen koeryhmän jäsenillä kuin kontrolliryhmäläisillä. Myös palveluiden käyttö oli säännöllisempää koeryhmässä. Karieksen hallintaa voidaan todennäköisesti tehostaa vaikuttamalla hampaiden harjaukseen, makeisten syöntiin ja suunterveyteen liittyviin asenteisiin. On tärkeää varmistaa, että nämä asiat ovat kunnossa, koska ehkäisevät toimenpiteet saattavat muuten jäädä tehottomiksi. Suunterveyteen liittyvistä asioista olisi hyvä keskustella perheissä, koska asioiden esillä pitäminen voi vaikuttaa suotuisasti lasten terveystapoihin. Koeryhmän saaman hoito-ohjelman kustannusvaikuttavuutta voisi todennäköisesti parantaa muuttamalla suunterveydenhuollon henkilöstön työnjakoa tai karsimalla valikoiden ehkäisevien toimenpiteiden määrää. Oikea-aikainen karieksen hallinta voi vähentää hoitokustannuksia ja lisätä hammasterveyttä pitkällä aikavälillä

Abstract:
AbstractThe introduction, establishment, and spread of invasive species in terrestrial and aquatic environments is widely recognized as one of the most serious threats to the health, sustainability, and productivity of native ecosystems (Holmes et al. 2009; Mack et al. 2000; Pyšek et al. 2012; USDA Forest Service 2013). In the United States, invasive species are the second leading cause of native species endangerment and extinction, and their costs to society have been estimated at $120 billion annually (Crowl et al. 2008; Pimentel et al. 2000, 2005). These costs include lost production and revenue from agricultural and forest products, compromised use of waterways and terrestrial habitats, harm to human and animal health, reduced property values and recreational opportunities, and diverse costs associated with managing (e.g., monitoring, preventing, controlling, and regulating) invasive species (Aukema et al. 2011; Pimentel et al. 2005). The national significance of these economic, ecological, and social impacts in the United States has prompted various actions by both legislative and executive branches of the Federal Government (e.g., the Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990; the Noxious Weed Control and Eradication Act of 2002; Executive Order 13112 of 1999, amended in 2016).

Abstract:
Initial therapy with intravenous heparin, followed by long-term anticoagulant therapy for three months or more, is the treatment of choice for most patients with acute venous thrombosis. Inferior vena caval interruption, using a transvenously inserted filter, is the management of choice for preventing pulmonary embolism in patients in whom anticoagulant therapy is contraindicated, and in the very rare patient in whom anticoagulant therapy is ineffective. The role of thrombolytic therapy has not been completely resolved. It was hoped that thrombolytic therapy would minimize or prevent the post-phlebitic syndrome; unfortunately, this may not be the case because the critical factor in the development of the post-phlebitic syndrome appears to be venous valve damage, which occurs early in the formation of venous thrombosis. Thrombolytic therapy should be considered in selected patients with acute massive venous thrombosis (eg. the patient with phlegmasia cerulea dolens).Intravenous heparin administered in doses which prolong the activated partial thromboplastin time (APTT) to 1.5 to 2 times control is highly effective and is associated with a low frequency (2%) of recurrent venous thromboembolism. A recent randomized trial (1) in patients with proximal-vein thrombosis indicates that failure to achieve an adequate anticoagulant response (APTT > 1.5 times control) is associated with a high risk (20%) of recurrent venous thromboembolism. Therefore, sufficient heparin should be administered to maintain the APTT above 1.5 times the control value.Intravenous heparin is continued for 7 to 10 days, overlapped with oral anticoagulant therapy for 4 to 5 days before heparin is stopped. Multiple randomized clinical trials in patients with proximal-vein thrombosis indicate that when heparin is administered for 7 to 10 days, followed by adequate long-term anticoagulant therapy, the frequency of recurrent venous thromboembolism is very low (2%). An alternative approach is to commence heparin and oral anticoagulants together at the time of diagnosis, and to discontinue heparin on the fourth or fifth day. If this latter approach is effective, it would avoid 4 to 5 days of unnecessary hospitalization in many patients, and would markedly reduce the cost of initial heparin therapy. A recent randomized trial (2) in patients with submassive venous thromboembolism suggests that 4 to 5 days of initial heparin therapy is effective and safe, but this approach must be evaluated by further randomized clinical trials before it is routinely recommended.Recent clinical trials indicate that inadequate long-term therapy in patients with proximal-vein thrombosis results in a high frequency (40-50%) of recurrent venous thromboembolism and is cost-ineffective because of the diagnostic and treatment costs of recurrent venous thromboembolism (3). The risk of recurrence is markedly reduced to 2% by adequate long-term anticoagulant therapy with warfarin sodium or adjusted subcutaneous heparin; both of these approaches are markedly more cost-effective than inadequate long-term therapy (3). Oral anticoagulant therapy with warfarin sodium for three months (or longer in selected patients), is less expensive than adjusted subcutaneous heparin and is preferred in most patients with acute proximal-vein thrombosis. The risk of bleeding associated with oral anticoagulant therapy can be reduced to less than 5%, without loss of effectiveness for preventing recurrent venous thromboembolism, by adjusting the dose of warfarin sodium to achieve a less intense anticoagulant effect (PT 1.25 to 1.5 times control using a rabbit brain thromboplastin such as Simplastin or Dade-C, corresponding to an INR of 2.0 to 3.0). Less intense warfarin sodium therapy is the most cost-effective of the alternative long-term anticoagulant regimens (3). Adjusted dose subcutaneous heparin is an effective and safe alternative to warfarin sodium; although slightly more expensive, it is the long-term regimen of choice in pregnant patients, and in patients returning to geographically remote areas lacking the facilities for anticoagulant monitoring (in whom the dose is adjusted during the first few days of long-term therapy and then fixed).
