a field experiment was conducted to evaluate the effect of varying doses of haloxifhope-r-methyl ester herbicide on grass weeds grown at various stages in 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried out as split split plot based on randomized complete block design with three replicates. treatments were haloxifhope-r-methyl ester ...

a field study was conducted to evaluate the effect of haloxyfop-r-methyl ester doses in different grass weeds in various growing stages in safflower during 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried our as split split plot based on randomized complete block design with three replicates. the main factor, sub factor and sub sub fa...

in order to investigating theeffects of  crop rotation and applying of herbicides on weed distribution in  irrigated wheat fields of kermanshah province, this study was performed during  2011-2012. multivariate analysis (rda) revealed the significant relationship between composition and species frequency and exerted management techniques. the first and second features of rda indicated 57%, 74.9...

efficacy of many herbicides to control broad- and narrow-leaf weeds (grass weeds) in tobacco fields of mazandaran and guilan provinces was investigated. the experiment was randomized complete blocks design in four replications and the following treatments: eptam (eradicane 82% ec) at 6 l.ha-1 which incorporated pre-planting (ppi), trifluralin (treflan 48% ec) at 2 l/ha ppi, cycloate (roneet 72....

in order to study the efficiency of dual-purpose herbicides at different stages of wheat (triticum aestivum), an experiment was conducted at shoushtar in 2012. the experiment was factorial with randomized complete block design arrangement of factors and four replicates. factors were dual-purpose herbicide including apyros (sulfosulfuron), total (metsulfuron methyl+sulfosulfuron), chevalier (iod...

over the past 20 years since tribenuron-methyl herbicide registration in iran, reports of erratic control of broadleaf weeds with it have increased in wheat fields of aq qala. in order to evaluate the incidence of resistance in wild mustard (sinapis arvensis) and turnipweed (rapistrum rugosum) to tribenuron-methyl herbicide, dose-response assays were conducted during the years 1390 and 1391 at ...

Six field trials were conducted over three growing seasons to evaluate both pre-and post-emergence applications of the recently developed herbicide mesotrione, for weed control in maize. As a pre-emergence treatment it provided excellent control of broadleaf weeds (>99% reduction in dry matter) but was poor on grass weeds (ca 80% reduction). However, its combination with atrazine, s-metolachlor...
