Because of the increasing number of glyphosate-resistant weeds, alternate herbicide-resistant crops and herbicides with different modes of action are required to protect crop yield. Glufosinate is a broad-spectrum POST herbicide for weed control in glufosinate-resistant crops, including soybean. The objective of this study was to compare herbicide programs with glufosinate applied singly at lat...

abstract limited number of herbicides are used to control weeds in soybean, which has herbicides resistance in consequence, so cultural weed management can be used in order to evaluate the effect of planting dates of soybean cultivars on weed management an experiment was conducted in randomized complete block design (rcbd) with four replications and with strip plot arrangement in sari. two plan...

A herbicide resistant Euglena mutant (MSI) has been obtained by adapting wild type cells to increasing concentrations o f D C M U (3-(3',4'-dichlorophenyl)-l ,1-dimethylurea). Lower re­ sistance levels towards D CM U and metribuzin were observed in MSI when compared with Euglena or C hlam ydom onas mutants with Ser 264 to Ala substitutions. RNA-sequence analysis identified a Ser to Thr change a...

to study the effect of different weed control methods in tomato, an experiment was conducted as completely randomized block design with three replications at the research farm of university of tehran (karaj) in 2008. the treatments consisted of post emergence (at recommended rate) or pre emergence (reduced rate in combination with mulch) application of metribuzin, rimsulfuron and sulfosulfuron,...
