Abstract:

The action of some foliar herbicides and herbicide combinations for control of common wheat (Triticum aestivum L.) weeds was studied. To that end against the background of soil applied Stomp 330EK New at a dose of 5 l/ha the herbicides Axial 050EK, Granstar 75DF, Derby Super WG, Sekator OD, Lintur 70WG, and the tank mixtures of Axial with the other herbicides applied in the tillering phenophase of the crop were studied. The species composition and density of weeds was assessed using the quantitative method prior to treatment and after herbicide treatment on days 5, 15 and 30, by constant meter

Abstract:

One of the most consistent recommendations, from both the private and public sectors, for the prevention and management of herbicide-resistant weeds is to rotate herbicides with different sites of action. Therefore, it is imperative that those who make herbicide recommendations and those who apply herbicides know which herbicides have the same or different sites of action. An herbicide's site of action is not obvious from its trade, common, or chemical name, and it is not possible to determine from the label if it has the same site of action as another herbicide.

Abstract:

In recent years considerable research in the private and public sectors has been directed toward introducing herbicide tolerance into normally susceptible crop species (9). Interest in developing herbicide-tolerant crop cultivars, clones, or hybrids (HTCs)3has been spurred by the reduction in the rate of discovery of new herbicidal compounds, the rising expense of developing new herbicides, and new tools of biotechnology that greatly increased our ability to develop HTC genotypes. Potential benefits of developing HTCs include: a) an increased margin of safety with which herbicides can be used

Herbicides are chemical preparations intended to destroy plants, especially weeds, or to obstruct their growth. After field application, herbicides not only control targeted weeds, but may also have possible lingering effects in the soil, and provide significant exposure of microorganisms to the herbicides.

Results of different studies show that herbicide application resulted in the reduction of some microbial species, e.g., Proteus spp., and Actinomycetes spp. Bacillus spp. and Pseudomonas spp. these are the micro

Abstract:

When herbicides are combined under natural conditions or applied in stress conditions (drought, for instance), the efficiency of their action may decrease which results in considerable yield losses. The reason thereto is that another herbicide or stressor can trigger the adaptation mechanism in weed plants, and they survive, resulting in weed infestation. In particular, it applies to such herbicides as acetyl-CoA-carboxylase inhibitors or so- called graminicides, which are effective only for grass weeds control. The efficiency of this groups of herbi- cides is heavily dependent on the environm

Combining these herbicides with dietholate, an enzyme inhibitor, prolonged persistence and restored normal herbicidal activity. Expected herbicidal efficacy occurred in adjacent plots with no history of carbamothioate use. Prior applications of butylate resulted in cross-adapte

Abstract:

To date, effectively controlling resistant weeds has been a great challenge in modern agricultural production. Developing new modes of action of herbicides would be an efficient, convenient, and timely means of controlling resistant weeds. In particular, new modes of herbicide action do not appear to have evolutionary resistance or cross-resistance with existing herbicides. However, a few successful herbicides with new modes of action (MoAs) have been marketed in the past 20 years. In this paper, we analyzed limiting factors for the slow development of novel herbicide MoAs. We then summarized

Abstract:

The use of chemical herbicides to control weeds is part of the growing process for most major crops. However, if applied regularly, they can lead to contamination of soil and groundwater, as well as accumulation of residues in crops and the emergence of resistant weed populations. In this regard, it is important to develop environmentally friendly chemical herbicides with new mechanisms of action. Natural phytotoxins of plant or microbial origin can serve as prototypes of active substances.

Abstract:

Auxinic herbicides are widely used for control of broadleaf weeds in cereal crops and turfgrass. These herbicides are structurally similar to the natural plant hormone auxin, and induce several of the same physiological and biochemical responses at low concentrations. After several decades of research to understand the auxin signal transduction pathway, the receptors for auxin binding and resultant biochemical and physiological responses have recently been discovered in plants. However, the precise mode of action for the auxinic herbicides is not completely understood despite their extensive u
