Weed populationThe study is based on data from a long-term field experiment of extent and duration seldom found in weed science. Yield losses from weed infestation of individual crops and crop rotations were studied in a field trial conducted since 1972 at two sites in the Czech Republic. The...
fumigant- a chemical substance used in fumigation herbicide,weed killer,weedkiller- a chemical agent that destroys plants or inhibits their growth intermediate- a substance formed during a chemical process before the desired product is obtained
In addition, as the greatest quantity of weeds was to be found during the rainy season, when there is the greatest amount of work to be done on the farm, it can be appreciated, that unless a very large labour force was kept solely for that purpose, the acreage of lucerne that could ...

”In general, CWA hydrolysis and degradation products have been found to exhibit a higher degree of stability and persistence in the environment than their corresponding parent agents.”– page 242 ”The improvement of ion mobility orthogonal time-of-flight mass spectrometer [IM(tof)MS] development...
[87] tested the variable rate split fertilization in wildblueberryfields and found that split variable rate fertilization can significantly reduce the volatilization losses. Overall, most of the studies have showed that PATs adoption in various cropping systems have positive impacts onsurface water, ...
taller (24 cm) and healthier compared to other weedicides treatments. Maximum nunber of dicots and monocot weeds were found in control plots , consequently seedling growth was very much suppressed. The studies indicated that pre- emergence chemical weedicides could be effectively used to control ...
Dr.Roger Leonard, LSU AgCenter entomologist, said farmers planning to grow wheat this winter should consider varieties with resistance to the Hessian fly. He said once the insects are found, no insecticide is available to control the pest. The insect can overwin...
has been working to improve food safety standards for more than a decade. He said he and his team at EWG had a lab test involving "45 samples of products made with conventionally grown oats" and found glyphosate – the active ingredient in the Monsanto weed-killer Roundup – in all but ...
the phenoxy herbicides were never considered as replacements for cultivation because they gave poor control of grasses and sedges. Other chlorinated organic compounds found some uses, such as benzoic acids (e.g., benzac), acetic acids (e.g., TCA and fenac), acetamides (e.g., CDAA and CD...
