Field efficacy trials showed that nicotinic acid, octaclor bromoxynil and fluroxypyr 19% oil suspending agent were sprayed on the stems and leaves of the spring corn field to control a variety of annual and monocotyledonous weeds in the spring corn field The effect is good, the herbicide is broad-spectrum, the quick-acting is good, and the persistence period is long. After 30 days of drug application, the control efficacy of the plants is above 95%, the fresh weight control efficiency is above 97%, the safety of spring corn is 80-200mL / 667m2, Considered from the cost, the recommended dosage is 100 ~ 120mL / 667m2.
