Abstract:

Master of Science<br>Department of Grain Science and Industry<br>Dirk E. Maier<br>Fumigation of stored grain is a common way to kill stored-grain insect pests. However, fumigating in unsealed structures is the leading cause of control failures and subsequent development of insect resistance. Sealing the storage structure is the only practical way to ensure a complete kill of all insects at all life stages. The cost, effort, and feasibility of sealing a U.S. corrugated steel silo during construction was evaluated and compared against an Australian sealed silo designed for fumigation. Gas monito

Abstract:

Soil microorganisms have a variety of beneficial and deleterious effects on plants, impacting such processes as plant growth, soil nutrient cycling, crop yield, disease resistance and tolerance to an array of biotic and abiotic stressors. The disruption of soil microbial community structures, particularly when beneficial soil biota are altered, has been shown to reduce crop yield and leave plants susceptible to disease. Long-term disruption of microbial communities may occur with repeated fumigation, being the application of gaseous pesticides, in agricultural soils. For this reason, we charac

Abstract:

Alcohol fuels have been shown to be very attractive alternative fuels for automotive use. They are considered to be cleaner fuels for protection of the environment and they are good alternatives to petrol because of higher octane numbers. Use of alcohol fuels in compression ignition engines has also attracted worldwide interest due mainly to its ability to burn without producing particulate emissions. This study shows that an inexpensive conversion system developed on a small single cylinder research engine enables a diesel engine to operate on near 100 percent methanol or ethanol. A computer

Abstract:

<p> California grows more than 91% of fresh strawberries in the United States. Critical to this success has been management of soilborne diseases using pre-plant soil fumigation with methyl bromide.

Reduced availability of methyl bromide has coincided with increased incidence of soilborne diseases affecting strawberry production, including Verticillium wilt, caused by <i> Verticillium dahliae</i>, and Black Root Rot (BRR).

Abstract:

A field test was established in 1999 to determine the effect of preplant soil fumigation on yield of chile pepper in southeastern Arizona in order to give growers data on which to base management decisions. Replicated plots within a nematode-infested field planted with New Mex 6-4 chile in March 1999 were either treated with Telone II fumigant at 7 gal/A two weeks before planting or not treated. In a mid-season assay in July 1999, the effects of fumigation were evident in plant canopy growth although numbers of J2/cc soil were not significant between treatments (p=0.058).

Abstract:

Fumigation before strawberry (<i>Fragaria×ananassa</i> Duchesne) planting was a common practice as they are susceptible to numerous pests. Methyl bromide, the colorless, odorless gas, was the chosen fumigant for growers until it was classified as an ozone-depleting substance and its use was gradually restricted and legally phased in 2015. Fumigant use has constraints and thus research on other preplant alternatives for soil sterilization of strawberry annual plasticulture production is necessary.

Abstract:

Recently, major advances have been made in developed countries elucidating the effects of air pollutants on crop plants. In contrast, similar studies on the effects of elevated SO2 concentrations on crops in developing countries such as South Africa are far less advanced. In South Africa, fossil fuel combustion is the main source of energy for most of the country. The tremendous increase in population size and consequental increase in energy demand has lead to considerable increases in fossil fuel burning. This phenomenon has lead to increases in tropospheric air pollutants such as SO2, NO2 an

These organisms are often controlled using organosintetics insecticides, however, mostly products are inefficient. This problem has generated a growing demand for environmentally safe products to control these pests. Thus, in order to contribute with new methods of control, the aim of this work was to evaluate the ant activity of essential oil of A. trilobata and

Abstract:

Methyl bromide (MBr) was widely used as a soil fumigant to manage soilborne pests in plasticulture vegetable production; however, it has been banned by the United Nations Environment Programme. Alternatives to MBr must be implemented to sustain fresh market tomato productivity. Possible MBr alternatives include new fumigant compounds, improved plastic mulch, and grafting. Methyl iodide (MeI) and dimethyl disulfide (DMDS) were tested as fumigant alternatives to MBr for the control of yellow nutsedge and soilborne pathogens of tomato.

Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The maize weevil (Sitophilus zeamais) is one of the stored grain pests of major importance in the world. The indiscriminate use of conventional insecticides has led to the selection of populations of resistant S. zeamais. Although the essential oils (EO) of plants are considered an alternative to conventional insecticides, their range of use due to insect populations with different capacities resistance has not been determined. We examined the toxicity of the EO of Pogostemon cablin and its nanoemulsion on nine populations of S. ze

Abstract:

Desenvolveu-se um sistema de alimentação misto para motores de ignição por compressão turboalimentados, o qual utiliza diesel injetado normalmente na câmara de combustão e etanol pós-vaporizado, injetado líquido no coletor de admissão e vaporizado pela grande disponibilidade de energia contida no ar comprimido. Foram possíveis substituições de até 55% da massa de diesel por etanol; funcionamento regular e repetitivo foi verificado, resultado da admissão de álcool na forma de vapor. Constatou-se que o rendimento térmico e as emissões de gases poluentes eram bastante influenciados pelo sistema d

Abstract:

This Project identified the relationships between storage conditions, dry matter losses (DMLs) caused by Fusarium species in cereal grains and mycotoxin contamination and assessed novel control strategies for post-harvest grain management including chemical control and ozone. F. graminearum, F. verticillioides and F. langsethiae were inoculated on wheat, maize and oats and stored under environmental conditions where marginal to optimum spoilage and mycotoxin contamination can occur. DMLs were calculated from the CO2 produced and were significantly correlated with deoxynivalenol (DON), zearalen

Abstract:

Ce travail de thèse est dédié à la mise en place d’une stratégie de valorisation optimale et raisonnée des cultures intermédiaires piège à nitrates de B. juncea (moutarde brune) dans un concept de bioraffinerie et de développement durable. Les graines de moutarde sont riches en huile (>35%) mais également en glucosinolates (≈ 120 µmol/g), facteurs antinutritionnels produisant de ce fait des tourteaux impropres à l’alimentation du bétail alors qu’ils sont riches en protéines de qualité. Ce travail de thèse a pour ambition de lever ce verrou en extrayant ces facteurs antinutritionnels de la g
