摘要:

为明确浙北桐乡地区油菜菌核病在不同栽培方式下的防治情况,开展药剂试验。结果表明:油菜菌核病在直播田块较移栽田块重。腐霉利与多菌灵在不同栽培方式的田块下防治效果不同,腐霉利防治效果均好于多菌灵。每667 m2腐霉利的农药使用量仅为多菌灵的五分之一,单位面积减少农药用量明显。腐霉利可以推广代替多菌灵用于防治油菜菌核病,这可为防治油菜菌核病减药增效提供一定的技术参考。

关键词: 油菜菌核病, 多菌灵, 腐霉利, 减药增效

Abstract:

This article studies through the fungicide tests in rape fields under the two cultivating ways of direct seeding and transplant, in order to find out the control of Sclerotinia sclerotiorium(Lib.)de Bary on rape in different farming methods in Tongxiang,north of Zhejiang Province.It shows that Sclerotinia sclerotiorium(Lib.)de Bary occurs more severely in direct seeding plot than in transplant plot.Both procymidone and carbendazim bring out the different control effect under the different cultivating ways,the effect of procymidone is better than that of carbendazim in both ways.Meanwhile,the application amount of procymidone per 667 m2 is one fifth of carbendazim, and the reduction of fungicide use per unit area is obvious.Procymidone can be used to control Sclerotinia sclerotiorium(Lib.)de Bary on rape instead of carbendazim,it could reduce the amount of fungicide use and improve the efficiency for reference.

Key words: Sclerotinia sclerotiorium(Lib.)de Bary, carbendazim, procymidone, reduce drugs and increase efficiency
