小麦“一喷三防”:指的是将杀虫剂、杀菌剂、植物生长调节剂(如微肥、抗旱剂等)混配,一次施药可以达到防病虫害、防干热风、防倒伏、增加粒重的目的。一喷三防指的是:防虫、防病、防干热风。

病虫害

病害:纹枯病、根腐病、茎基腐病、全蚀病、锈病、白粉病、叶枯病、赤霉病等。其中以纹枯病、茎基腐病、锈病、白粉病、赤霉病的危害较大。

虫害:蚜虫、红蜘蛛、吸浆虫、麦叶蜂、金针虫、蛴螬等,以蚜虫的危害较大。气候性灾害:主要是干热风、扬花期阴雨等。

小麦孕穗期(4月15日-5月17日)

这个时期主要预防白粉病、锈病、纹枯病、赤霉病等以及促进小麦孕穗健壮。可以加入适当苯甲丙环唑、肟菌戊唑醇、咪鲜胺·戊唑醇来预防。

重点防治小麦赤霉病。小麦赤霉病最容易在抽穗扬花期发生,也就是4月中旬到5月中旬之间,因此防治一般在这个阶段进行效果较好。小麦赤霉病应以预防为主,若在扬花期染病,灌浆期可能才会出现严重后果,而这时候是很难阻止病害的。

赤霉病防治时期:当小麦刚开始扬花(大概20%),可以喷施药剂进行预防和控制,“见花打药”就是在扬花前期开始施药。宜早不宜晚。可以选用:咪鲜胺·戊唑醇、氰烯菌酯、噻霉酮、苯甲丙环唑、肟菌戊唑醇,预防白粉病、锈病、纹枯病、赤霉病等,同时适当加入磷酸二氢钾、硼肥促进小麦孕穗健壮。

小麦孕穗期—灌浆期

这两个时期主要防治虫害、干热风以及未防治住的赤霉病,防止其蔓延。穗蚜、吸浆虫:高效氯氟氰菊酯(功夫)或者联苯菊酯+噻虫嗪或者吡虫啉防止赤霉病叶枯病蔓延:40%戊唑醇咪鲜胺、氰烯菌酯。防止干热风:叶面喷施高含量磷酸二氢钾是防御小麦干热风的手段,没有之一。(吾谷)
