摘要
供试新农药均为三唑类杀菌剂。试验和示范结果表明,保丰宁和粉锈铜与生产上已经推广的粉锈宁在用量相同情况下,对小麦白粉病的防治和增产效果相近;植保宁的防效稍差,但大面积示范结果与粉锈宁无显著差异。温室和田间试验表明,三唑醇比粉锈宁等药剂用量减少一半,防效相近。
The new fungicides,Baofengning,Fenxiutong and Zhibaoning used
in the studies are triazoles.In field plots and large scale trials the
three fungicides gave good effectiveness for control of powdery mildew
of wheat.The effect of Baofengning and Fenxiutong were not signifi-
cantly different from Triadimefon at the same dosage and for applica-
tions on a large scale.The effect of Zhibaoning was less than that of
Triadimefon in small plots,but no different in large scale trials.
Owing to the lower cost fungicides than Triadimefon,we suggest that
one or two from them be chosen to produce for applications.
The results in field plots and greenhouse experments showed that
Triadimenol at a half dossage of Triadimefon gave the similar control
effect to powdery mildew as the later did.But the large scale applied
trails were not conducted yet.
