Malathion in mixture with acetolactate synthase (ALS)-inhibiting herbicides synergizes the control of weed species that have evolved metabolism-based resistance to ALS-inhibiting herbicides. However, the effect of malathion-based herbicide programs on conventional and imidazolinone-resistant (Clearfield) rice systems still need to be evaluated. Studies were conducted to determine the tolerance ...

Some imidazolinone herbicides have been shown to be mobile in soil, raising concern about their possible movement to ground water. Three imidazolinone herbicides (imazamethabenz-methyl, 497 g ha(-1); imazethapyr, 14.7 g ha(-1); and imazamox, 14.7 g ha(-1)) commonly used in crop production on the Canadian prairies were applied to a tile-drained field to assess their susceptibility to leach when ...

ABSTRACT Environmental conditions can influence herbicide metabolism and interfere with the evolution of weed resistance. This study aimed to evaluate effect thermal regimes on control barnyardgrass (Echinochloa crus-galli) susceptible resistant herbicides imidazolinones chemical group. Factor A (biotypes) consisted one biotype that is imazethapyr; factor B (dose) comprised six imazethapyr dose...

Bu araştırma 2017 ve 2019 yılları bitki yetiştirme döneminde iki yıl süre ile Eskişehir Osmangazi Üniversitesi Ziraat Fakültesi deneme tarlalarında farklı yabancı ot kontrol yöntemlerinin nohut’ta verim ögeleri üzerine etkisini belirlemek amacıyla yürütülmüştür. Araştırmada Azkan nohut çeşidi linuron (çıkış öncesi), aclonifen sonrası) imazethapyr öncesi) herbisitleri materyal olarak kullanılmış...

Green pigweed [Amaranthus powellii S. Wats.] is a competitive, annual, broadleaf weed that can significantly reduce soybean yield due to rapid early growth and biomass production. As consequence of green pigweed’s high competitiveness with crops, the species generally managed use herbicides; this may, however, lead selection resistance. A biotype resistance MCPA, mecoprop, dichlorprop-p, aminoc...

Lentil (Lens culinaris Medikus) is an important grain legume crop. Among all the biotic factors, weed infestation being adverse impact on growth, yield, nutrient uptake and economics due to lentil short stature, low branching, lack of protective canopy it’s unable smother weeds. Although, applying pre emergence herbicides, in many situation early control herbicides are not that much efficient f...

Common ragweed emerges early in the season in Nebraska, USA and is competitive with soybean; therefore, preplant herbicides are important for effective control. Glyphosate has been used as a preplant control option; however, confirmation of glyphosate-resistant (GR) common ragweed in Nebraska necessitates evaluating other herbicide options. The objectives of this study were to (1) evaluate the ...

Herbicide plays the main role in guaranteeing the quantity and quality of food. Soybean reactive oxygen species scavenging system eliminates the herbicides’ side effects on the plant by activating antioxidant enzymes, which affects the yield. So, we investigated this procedure to reveal the effect of herbicides on food production. Methods: Experiments were carried out in two locations of Alborz...

abstractgrowth of b. japonicum isolates at different concentrations of herbicide used on soybean was studied as factorial experiment arranged in a completely randomized design with three replications. isolates b1, b6, b43 and 0, 0.125, 0.25, 0.5, 1, 2, 4, 8 and 16 folded of the recommended doses of trifluralin, metribuzin and imazethapyr herbicides were considered as factors. isolates populatio...

experiment was conducted in 2011 to evaluate the efficacy of reduced herbicide rates in combination with false seedbed for selective weed control in common bean. the experiment was carried out with a completely randomized factorial design. factors were herbicide dose (post-emergence application of imazethapyr at the rates of 0, 25, 50, 75, and 100 g a.i. ha-1) and seedbed preparation (false see...
