高原小麦、青稞田阔叶杂草的防除研究

摘要

Experiment of 10% tribenuron-methyl WP mature with 20% fluoroglycofen EC for controlling broadleaf weeds in wheat and highland barley fields was conducted in plateau. The results showed that the significant effect of 10% tribenuron-methyl WP mixture with 20% fluoroglycofen EC was observed, and the highest control effects of mixture of 10% tribenuron-methyl WP mixture with 20% fluoroglycofen EC in wheat fields ( (225g +450mL)/hm2 ) were 92.6% and 93.2% after 10 and 20 days, respectively, the highest control effects of mixture of 10% tribenuron-methyl WP mixture with 20% fluoroglycofen EC in wheat fields [ (225g +450mL)/hm2 ] in highland barley fields were 86.1% and 88.9% after 10 and 20 days, respectively.%使用10％苯磺隆可湿性粉剂和20％乙羧氟草醚乳油混用对高原小麦、青稞阔叶杂草进行了除草试验.结果表明,10％苯磺隆可湿性粉剂和20％乙羧氟草醚乳油混用对小麦、青稞田杂草具有较好的防效.药后10 d,10％苯磺隆可湿性粉剂+20％乙羧氟草醚乳油混用对小麦田阔叶杂草防效最高可达92.6％,药后20 d防效最高可达93.2％;药后10 d,10％苯磺隆可湿性粉剂+20％乙羧氟草醚乳油混用对青稞田阔叶杂草防效最高可达86.1％以上,药后20 d防效最高可达88.9％.生产上推荐使用10％苯磺隆WP+20％乙羧氟草醚EC[ (225g +450mL)/hm2]混用防治高原小麦、青稞田阔叶杂草.
