不同浓度杀菌剂对玉米大斑病的防控效果及其评价
|
摘要
[目的]明确杀菌剂减量施用对玉米大斑病的防控效果。[方法]选用2种杀菌剂,以正常施用剂量为对照,各减量15%、30%为处理,研究其对玉米大斑病的防控效果。[结果]在减量15%用量的情况下,2种杀菌剂均达到了与常规用量同样的防控效果与产量水平,防治效果分别达68.37%和56.14%,增产幅度分别达15.08%和12.23%。[结论]杀菌剂减量15%施用的方法在玉米大斑病防控上确实可行,不但降低了生产成本和环境污染,同时达到了对大斑病预期的防控目标与产量水平。
[Objective]To clear the prevention and control effect of applying reduced fungicide on corn northern leaf blight.[Method]Choosing two fungicides,the prevention and control effect of 15% and 30% of normal dosage on northern leaf blight of corn separately was investigated with application of common fungicide dose as contrast.[ Result] Reducing 15% of two fungicides dosage were used to prevent maize northern leaf blight and the prevention effect was up to 68.37% and 56.14% separately,and yield increased by 15.08% and 12.23%, respectively,which reached the normal prevention and control effect and production level of maize.[Conclusion]The experiment indicates that it is really available for fungicide dosage is about 15% of normal dosage,it also reduces the production cost and environment pollution, meanwhile,achieves the anticipated prevention and control goal on corn northern leaf blight and production level of maize.
