Effect of Herbicide Acetochlor on Weed Control in Potato Field
摘要
Abstract
The control effects of acetochlor on various kinds of weeds in potato field were examined by the randomized block design. Acetochlor was sprayed after sowing immediately (Treatment A) and in 14 days after sowing (Treatment B) , respectively. The results showed that soil-applied herbicide (acetochlor) within the scope of 2. 25~3. 75 L · hm-2 could prevent monocotyledonous and dicotyledonous weed effectively. The results in 15 days after seedling showed that control efficacy of treatment A and B was 93. 08%~95. 28% and 93. 0%~97. 16% , the total fresh weight control efficacy of treatment A and B was 94. 6%~99. 37% and 94. 6%~99. 37%, respectively. Acetochlor in both treatments had no adverse effects on potato growth. Considering the damage for the following crop, formulated acetochlor at 3. 00 L · hm-2 was recommended to be sprayed after sowing immediately, which had a better control effect.关键词
