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:

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.

Rice (Oryza sativa L.) is the most important food crop catering half of the world’s population. India being the second largest producer of rice, needs to produce around 120 million tons of rice by 2030 to feed its one and a half billion plus population. Weeds are undoubtedly a major biotic constraint to rice production in most of the rice growing areas of the world. Rice fields are very often characterized by a complex plurispecific weed flora, comprising of grasses, sedges, and broad-leaved weeds (BLWs). They usually grow faster than rice and absorb available water and nutrient earlier than t

Abstract:

Combinations of antagonistic herbicides can be helpful in the search for seed-applied chemical safeners to protect crop plants from herbicide injury. If a particular herbicide combination is selectively antagonistic so that the crop is not injured but weed control efficacy is not reduced, it should be possible to develop a new, more selective formulation of the herbicide which includes the antagonist or antidote. A promising new approach involves the use of early pretreatments of crop plants with subtoxic levels of a particular herbicide to increase crop tolerance to later, higher rates of tha

To minimise herbicide inputs, reduce environmental burdens, and delay the evolution of herbicide resistance, it is of the utmost significance to study the interaction between herbicides. This may be accomplished by selecting the optimal combination, which, through synergy, delivers more cost-effective weed control than a single herbicide. Under laboratory conditions, interactions between binary mixtures of bensulfuron, propanil, 2,4-D, or bentazon on chlorophyll reduction of Lemna minor were investigated using the Additive Dose Model.

Abstract:

The over-reliance on the herbicide glyphosate for knockdown weed control in fallows under minimum and zero-till cropping systems has led to an increase in populations of glyphosate-resistant weeds. Echinochloa colona and Chloris virgata are two major grass weeds in the cropping regions of northern New South Wales and southern Queensland, Australia, that have become harder to kill due to a steady rise in the occurrence of glyphosate-resistant weed populations. Therefore, to help growers contain these hard to kill fallow weeds, an alternate approach to glyphosate application is needed. With this

A field experiment was conducted at 2 locations, Ludhiana and Gurdaspur, Punjab, during kharif 2017, to deter- mine the effect of paddy straw mulching and herbicides on reduction of herbicide load in maize (Zea mays L.). Paddy straw mulch (PSM) at 9.0 t/ha resulted in highest weed-control efficiency, yield parameters, net returns, benefit : cost ratio and lowest weed index as compared to PSM 6.25 t/ha and no mulch treatments. Post-emer- gence application of tembotrione at 0.088 and 0.110 kg/ha resulted in highest WCE (96.3%) and was effective in lowering weed density and biomass as compared to

Abstract Dichlormid, a safener for thiolcarbamate herbicides, was tank-mixed with several herbicidal inhibitors of photosystem II, or with the herbicide acifluorfen, and applied postemergence to Ipomoea hederacea plants. Dichlormid had no visible effects on the plants when applied alone, but interacted synergistically with the herbicides in the combination treatments. Dichlormid strongly decreased the ascorbic acid levels in the Ipomoea hederacea cotyledons. Ascorbate is known to protect plant tissue from photooxidative damage.

An extension program designed to encourage farmers to adopt herbicide rotation in favor of continuous use of acetyl-CoA carboxylase inhibitor herbicides was launched in 1991.

Adoption of herbicide rotation is estimated at approximately 40%, but producers who have started to rotate herbicides are assumed to be doing so on a limited "trial" basis.The use of this group of products continues at high levels due to a combination of producer preference for these chemicals and of reluctance to use alternative

Clemson University researchers have conducted studies aimed at determining the amount of herbicide runoff during normal nursery operation, if herbicides accumulate in containment ponds at nurseries, and how herbicide runoff could be reduced. A 2-year study at commercial nurseries found that herbicide concentrations were higher in containment ponds soon after herbicide application, when compared with months with less herbicide application; and herbi

Soil-residual herbicides can be applied to the soil under grapevines during fall or spring before weed emergence. But, early spring moisture and warm weather conditions may enhance weed emergence before spring herbicide applications.

Absorption, translocation and metabolism are processes affecting the efficacy of sulfonylurea herbicides. These processes contribute significantly to selectivity but are also known to effect the development of plant resistance to this group of herbicides.

The level of absorption depends on numerous factors such as: development stage of the plant, ambient temperature, soil humidity, fertilizers added to herbicides, application in combination with other herbicides, sufactants, plant cultivars, mode of herbicide applicatio
