玉米田除草剂环磺酮的作用特性及田间防效评价OACSCD
Herbicidal characteristics and field control efficacy evaluation of tembotrione in maize field
为明确玉米田除草剂环磺酮的最佳施药条件,通过温室盆栽法分别比较了模拟降雨、光照强度、温度和施药适期等条件下其对马唐活性的影响,并测定其杀草谱,同时评价了在玉米不同龄期施药对田间杂草的防效及对玉米品种'浚单 20'的安全性.结果表明:在环磺酮(有效成分,余同)27、54、108 g/hm2 剂量下,药后 4 h降雨对马唐的活性较对照无显著差异(P<0.05);强光照(100%)条件下环磺酮对马唐的活性显著高于中等光照(48%)和低光照(9%)…More>>
In order to determine the suitable application condition of tembotrione,the effects of simulated rainfall,light intensity,temperature,and application period on its herbicidal activity against Digitaria sanguinalis were compared in the greenhouse,and the weed control spectrum was determined.Meanwhile,the field weed control efficacy and the safety to maize'Xundan 20'were evaluated at different leaf stages.The results showed that there was no significant differ…More>>
