摘要:
为实现马铃薯早疫病农药减施增效，研究杀菌剂喷施时间及次数对马铃薯早疫病防治及产量的影响。结果表明：用代森锰锌与嘧菌酯混配在发病前一周或田间零星发病时喷施，用药2～3次，可以较好地控制早疫病，用药4次防效与用药2~3次没有显著性的差异，施药过晚防效差；适期用药3次产量较高，收入增幅也较大。
Abstract:
In order to realize saving and improving efficiency of chemical pesticides for potato early blight,the field experiments were carried out to study fungicide spray date and times on the control of potato early blight and its effect on potato yield.The results showed that early blight could be adequately controlled with two or three spays of the mixtures of mancozeb and Azoxystrobin if the initial application was a week before disease onset or was initial stage of disease onset,and four spays of fungicide were not significantly different in controlling the disease than were two or three times applications properly timed,and that there was low control effect of early blight with late fungicide application.Yelds,which were three spays properly timed,were higher than other treatments and increase income were also higher.
