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

The conventional herbicide 2-methyl-4-chlorophenoxyacetic acid (MCPA) provide substantial risk to the environment such as contamination of soil and groundwater. The overuse application of conventional herbicide can leave harmful residues in soil and be washed off as runoff, thus causes toxic effect to nontarget organism. For instance, MCPA can cause toxicity to the freshwater organisms such as Daphnia magna and alga Selenastrum capricornutum. Zinc oxide as nanomaterials that are intercalated with 2-methyl-4-chlorophenoxyacetic acid (ZMCPA) herbicide may be useful to resolve the problems associ

Microorganisms decompose herbicides and they may serve as bioindicators of soil changes following herbicide application. Certain microbial species may be used as bioherbicides. This study has shown that Azotobacter is most sensitive to herbicide application; it is, therefore, a reliable indicator of the biological value of soil. The numbers of this group of nitrogen-fixing bacteria decrease considerably in the period of 7-14 days after herbicide application. Simultaneously, the numbers of Actinomycetes and less so of fungi increase, indicating that these microorganisms use herbicides as source

Chickpea (Cicer arietinum L.) is the third most important grain legume crop in the world and the first important legume in the South and West Asia. For Bulgaria the chickpea is an old traditional crop used mainly for human consumption and to a lesser extent for feed. One of the most important yield limiting factors in the chickpea seed production is the poor weed management. The establishment of the most appropriate herbicide or herbicide combination for the effective control especially of the weed flora is a priority task of the chickpea cultivation.

The joint action experiments were independently run twice to substantiate the findings. The most potent individual herbicide was metribuzin, with a 50% lethal concentration (LC50) of 17.17 µg ai. cm−2 at 48 h in the filter paper test.

Simulated rainfall within 3 h after paraquat application decreased its herbicidal efficacy.

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.

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. Microorganisms play important role in maintaining soil structure and fertility. 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

O experimento foi conduzido em vasos contendo cinco litros de solo, com seis doses do herbicida fluazifopp- butil aplicadas em mistura com três herbicidas/mistura [glyphosate, 2,4-D e glyphosate + 2,4-D] em três formas de aplicação (mistura em

Agricultural production systems that reduce the use of in-crop herbicides could greatly reduce risks of environmental damage and the development of herbicide-resistant weeds. Few studies have investigated the long-term effects of in-crop herbicide omissions on weed seedbank community size and structure. A crop-rotation study was sampled 10 yr after a strictly annual rotation and an annual/perennial rotation were exposed to different in-crop herbicide omission treatments. In-crop herbicides were applied either in all annual crops (control), omitted from oats only, or omitted from both flax and

The effects of two herbicides on soil respiration, the activity of catalase and the activity of urease were studied in laboratory. The results showed that effects of atrazine and nicosulfuron on soil respiration were different. The soil respirations were in inhibition when soils were treated with atrazine, while soil respirations were in promotion-inhibition-recover when soils were treated with nicosulfuron. The soil respirations were different at different herbicide concentrations. According to coefficient of injury, herbicides atrazine and nicosulfuron both belong to low toxicity herbicides

In agricultural crop production, herbicides are typically used to prevent or control weeds and other plant pathogens by reducing crop losses and maintaining high product quality. This brief overview sheds light on the level of toxicity, mechanisms of toxicity, health effects and prevention strategies. Three main levels of toxicity have been identified in herbicides: acute (short-term exposure), sub-chronic (medium-term exposure), and chronic (long-term exposure). These levels of toxicity have detrimental effects on humans, animals, and the environment. Herbicides must be handled and administer

Thus, the objective of this experiment was to evaluate the effects of simple, double and triple association of broadleaf herbicides with graminicides to control of Italian ryegrass and horseweed.

India has wide range of agro-climates and soil types and highly diverse agriculture farming systems with different types of weed problems. So, herbicides are the integrated part of the general cropping systems. In general, herbicides are formulated in such a way that they degrade from the environment after completion of their intended work, but a few of them persist in the environment and cause a serious hazard to the succeeding crop and also to the surrounding environments. Hence, a proper knowledge of herbicides is important to understand the management procedure, organization and hierarchy

The physiological interactions of herbicides and their respective safeners are characterized by the following facts: a) safeners are most effective when applied prior to or simultaneously with the herbicides whose injury they prevent; b) safeners exhibit a high degree of botanical and chemical specificity protecting only certain grasses against injury caused from specific classes of herbicides; and c) protected grass crops are moderately tolerant to the
