The Effect of Adjuvant on Performance of Herbicides in Corn Weeds: the Effect of Adjuvant in Weeds Control of Maize Mojtaba Kahkeshpour

Corn is one of the essential crops in our world. Not only today but also in past. We can produce variety of products from corn, so planting of corn is important. We should produce more corn with less damage to environment. Today new methods are used to reduce the amount of herbicides dose. One of these ways is using Adjuvant or additives to increase the efficiency of herbicides. In this study we peruse the effect of some adjuvant on Nicosulfuron efficiency on agronomic traits of maize and some weeds density and biomass, a field experiment was conducted in research field of Miyaneh (Iran), based on randomized complete design with three replications. Treatments included T1: atrazine, T2: nicosulfuron + volck oil, T3: nicosulfuron + ammonium nitrate, T4: nicosulfuron + ammonium sulfate, T5: nicosulfuron + citogate, T6: nicosulfuron and T7: control. Results showed that the effect of herbicide and adjuvants application was significant on maize grain yield. Among different adjuvants, ammonium sulfate was more effective on studied traits than other adjuvants. Nicosulfuron plus ammonium sulfate increased grain yield 20.7% compared to control.
