The pH of the spray liquid is one factors influencing efficacy herbicides. Adjusting appropriate parameters spraying may reduce consumption pesticides, which in line with currently introduced legal standards and society’s requirements. In greenhouse experiment, influence herbicides containing mesotrione, nicosulfuron, rimsulfuron, bromoxynil, a mixture mesotrione on oilseed rape control was inv...

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...

First-derivative photochemically induced spectrofluorimetry (PIF-1D) is applied to the simultaneous determination of binary mixtures of 4 sulfonylurea herbicides in aqueous micellar samples. Synthetic binary mixtures of sulfometuronmethyl with chlorsulfuron, metsulfuron-methyl, and 3-rimsulfuron, respectively, are well resolved by using the zero-crossing point procedure. PIF-1D allows the deter...

introduction soil herbicides residue in agroecosystems is one of the important problems due to herbicides application. however herbicides residue in soil extend the period of weed control. nevertheless, it may persist longer than desired and injure subsequent crops in rotation. herbicides vary in their potential to persist in the soil. some herbicides such as sulfonylurea herbicides are very pe...

Abstract Downy brome ( Bromus tectorum L.) is a highly invasive winter annual grass that can fill open niches in native plant communities. Prescribed burning often used to control B. and be combined with herbicide treatments extend the duration of promote community. Several herbicides have been evaluated conjunction for control, although indaziflam has not. In September 2017, two –infested site...

Weeds are the major constraint to achieving higher wheat yield in Afghanistan. To evaluate weed interference and its impact on wheat, a field experiment was undertaken during winter season 2014–15 at Afghanistan National Agricultural Science Technology University (ANASTU), Kandahar. Seven control treatments comprising isoproturon 0.75 1.0 kg/ha 35 days after sowing (DAS), sulfosulfuron 20 25 g/...
