Abstract:
Taking cabbage‘Jingfeng No.1’ as material,with the method of spray and root dip,the occurrence of clubroot disease was surveyed in the main cabbage producing area of Xifeng county,Weining county and Yuqing county in Guizhou Province,and the control effect of three different pesticide application treatments on clubroot was tested in the more severe fields,in order to provide a reference for the control of cabbage clubroot disease in Guizhou.The results showed that the cabbage clubroot disease with varying degrees occurred in three different planting areas of Xifeng county,Weining county and Yuqing county,the average diseased plant rate was 30.00%-60.00%,the area with serious disease was Xifeng county,and diseased plant rate was as high as 60.00%,disease index was 45.93;the best field control effect was T2 treatment among different treatments in the same area,in the three experiment plots of Xifeng county,Weining county and Yuqing county,the control effect of T2 treatment was 73.40%-75.80%,followed by T1 treatment which was 68.00%-70.10%,the lowest was T3 treatment,the control effect was 61.10%-63.70%;the control effects of cabbage and chinese cabbage were different among different treatments,the highest control effect was T2 treatment as well,which was 74.40% and 71.06%,respectively.Through the actual harvest of cabbage，the highest average yield was T2 treatment,which was 123 511.80基 kg?hm-2基,according to the average purchase price of 0.50 RMB?kg-1基 was calculated in the local market.Compared with CK,T2 treatment was used to control clubroot that could increase income of 30 040.05 RMB?hm-2基.
