Weeds pose a serious threat to wheat productivity. A study was undertaken during the winter season of 2019/20 in experimental field, National Agronomy Research Centre, NARC, Khumaltar assess various doses and application dates for controlling mixed weed flora wheat. The experiment laid out Randomized Complete Block Design with ten treatments replicated thrice net plot size 6 sq. m. included met...

A field experiment was conducted at the Pulse Research Centre of Bangladesh Agricultural Research Institute, Ishurdi, Pabna during Kharif-II season of 2010 to evaluate the efficacy of five herbicides for controlling weeds associated with mungbean (BARI Mung-6). The five herbicides such were: Paraxon (27.6% WV Paraquat dichloride salt), M-clor 5G (Butaclor), Topstar 40 WP (40% Oxadiargyl), Hamme...

Herbicide mixtures are a modern weed management practice as they reduce herbicide application. This study aimes to evaluate the effect of metribuzin, halosulfuron and flumioxazin applied individually (metribuzin:halosulfuron metribuzin:flumioxazin) on Chenopodium album, Amaranthus retroflexus, potatoes biomass chlorophyll-a fluorescence in 21 experiments. The individual experimental design was ...

ABSTRACT The sesame crop has great economic potential due to the various possibilities of exploitation, however, there is a lack information about chemical control weeds in crop, mainly application herbicides pre-emergence. Therefore, objective this study was evaluate viability and efficacy applied pre-emergence for crop. experimental design randomized blocks, with four replications. treatments...

Pyrolysis temperature and application rate of biochar to soil can influence herbicide behavior fertility. The objective was investigate the effect amendments with rates sugarcane straw biochar, produced at different pyrolysis temperatures, on sorption–desorption metribuzin in soil. analysis performed using high-performance liquid chromatography (HPLC). treatments were three temperatures (BC350,...

Abstract The objectives of this study were to determine if the level and consistency glyphosate-resistant (GR) horseweed control prior soybean planting can be improved by (i) adding halauxifen-methyl, 2,4-D ester, saflufenacil, metribuzin, or dicamba glufosinate, (ii) increasing rate glufosinate from 500 1,000 g ai ha –1 , (iii) 28% urea ammonium nitrate (UAN) as carrier solution. During a 2-yr...

Residues of the herbicides simazine, metribuzin, metolachlor, trifluralin, atrazine, and two metabolites of atrazine, deisopropylatrazine (DIA) and deethylatrazine (DEA), are surveyed in the surface and groundwater of the Primavera do Leste region, Mato Grosso, Brazil during September and December 1998 and April 1999. Different water source sampling stations of groundwater (irrigation water wel...
