| Abstract | ||
| Various adjuvants carry out different functions depending on the herbicides types and the target species. Outdoor pot experiments were conducted to evaluate the effects of three post-emergence herbicides, namely, clodinafop-propargyl, haloxyfop-p-methyl, and difenzoquat-methyl-sulfate, as influenced by two adjuvants, on wild oat (Avena ludoviciana Durieu.) control. The study was carried out at the Ferdowsi University of Mashhad, Iran, during 2010. The applied adjuvants were Adigor® and Propel™, registered and sold for use with pinoxaden and tralkoxydim herbicides, respectively, at 0.1 and 0.2% (v/v). These two adjuvants in tank-mixture with the tested herbicides were completely compatible physically and resulted in improvement in controlling wild oats. When Propel™ was added to all three herbicides, herbicidal activity was higher than when Adigor® was added. With increasing adjuvant concentrations, the performance of the tested herbicides increased significantly. In general, the benefit of the two adjuvants appeared greater for clodinafop-propargyl than for the other herbicides. The performance against wild oat of clodinafop-propargyl, haloxyfop-p-methyl, or difenzoquat-methyl-sulfate plus Propel™ at 0.2% was higher by 2.92, 1.42, and 1.67 times, respectively, compared with the use of those herbicides without adjuvants. This result may be related to differences in the physio-chemical characteristics of the tested herbicides. Overall, use of Propel™ with clodinafop-propargyl is recommendable. | ||
