Abstract
In order to nail down the control efficiency of 34% Fluroxypyr - methyl Carfentrazone - elhy WP on the broadleaf weeds (cleavers, Capsclla bursa -pastoris. Euphorbia helioscopia, Veronica polita and Vinia mtiva) in barley field and its safety to barley, the relative control and safety tests were conducted from 2010 to 2011. The results showed that 34% Fluroxypyr - methyl Carfentrazone - ethy WP could be used for controlling several kinds of broadleaf weeds in barley field, barley would not suffer from the harm of weeds in the whole growth period after utilizing this herbicide once, it damaged the weeds rapidly, and the yield of barley increased obviously. The tested dosage was safe to barley and its following crop (cotton ). The suggested dosage of 34% Fluroxypyr -methyl · Carfentrazone - ethy WP was 450 g/hm2 at the 3 ～ 4 - leaf stages of barley and the 2 - leaf stage of weeds in winter, and 450 ～ 600 g/hm2 before the regreening and jointing stages of barley from the last ten - day of February to the first ten - day of March in spring.关键词
