不同药剂防治小麦赤霉病效果研究

选择30%丙硫菌唑可分散油悬浮剂、43%戊唑醇悬浮剂、75%肟菌·戊唑醇(拿敌稳)水分散粒剂、25%氰烯菌酯悬浮剂、30%唑醚·戊唑醇悬浮剂,进行小麦赤霉病药效对比试验。结果表明,30%丙硫菌唑油悬浮剂对小麦赤霉病防效好,达84.72%,且对小麦安全,适合在当涂地区防治小麦赤霉病上推广。

新美洲星+拿敌稳组合对小麦防病增产效果研究

新美洲星是安徽省神农农业技术开发有限公司研制的有机水溶肥料，拿敌稳是拜耳作物科学（中国）有限公司主推的杀菌剂产品。2018年当涂县植保站开展了新美洲星＋拿敌稳组合对小麦穗期综合防病增产效果研究，具体如下。

小麦赤霉病防治药剂筛选试验

为了筛选安全高效的小麦赤霉病防治药剂,研究了75%肟菌·戊唑醇水分散粒剂、40%戊唑·咪鲜胺微乳剂、30%唑醚·戊唑醇悬浮剂、25%氰烯菌酯悬浮剂、40%戊唑·多菌灵悬浮剂在当涂县的应用效果。结果表明,上述药剂对小麦赤霉病防效较好,且对小麦安全。由于2018年小麦齐穗—扬花期雨水多,赤霉病发生偏重,分别于扬花初期喷施75%肟菌·戊唑醇水分散粒剂225 g/hm^2,7 d后喷施75%肟菌·戊唑醇水分散粒剂225 g/hm^2或25%氰烯菌酯悬浮剂3 000 mL/hm^2,开展2次防治,对赤霉病防效优异,值得在当地推广。

An Unusual Trip

Last Saturday,John,Mike and I went on a hike.It was sunny.We had a good time there.Soon it was time to go back home and we were tired.We began to walk back.It was completely dark and we got lost.Suddenly,Mike had a fall and hurt her1 leg.We helped him to walk slowly.We were cold and hungry.Luckily we saw a light not far away.It was a small house!We knocked at the door and an old man came out.He invited us to stay for the night.The next morning,with the help of the old man's son,we went back home safe2.
