Abstract:
Biocontrol strains BCJB01 and BMJBN02 were used as test bacteria,the field efficacy trials of grape downy mildew were studied in Shandong Province,Jinan and Yantai vineyards respectively,to defining the effects of BCJB01 and BMJBN02 on the control of downy mildew of different grape varieties,and exploring the control techniques,provide the theoretical basis for the popularization and application BCJB01 and BMJBN02 preparations.The results showed that the control effects of 20 mL?L-1 BCJB01 bacillus and BMJBN02 suspending agent on ‘Zeshan No.1’ were 84.05% and 73.30% respectively at the beginning of the grape downy mildew.The control effects of 20 mL?L-1 BCJB01 bacillus and BMJBN02 suspending agent on ‘Cabernet Gernischt’ was above 62% when they could be used in alternation.The control effects of 20 000 mg?L-1 BCJB01 soluble powder and 0.1% assistant on ‘Cabernet Gernischt’ was 81.31% while 6 667 mg?L-1 BCJB01 soluble powder and 0.1% assistant reduced disease severity to 61.29%.In the full incidence period of downy mildew,the control effects of 20 000 mg?L-1 BCJB01 soluble powder and 0.1% assistant on ‘Cabernet Gernischt’ was 81.31%.It was effective on controlling ‘Summber black’ grape downy mildew by using 6 667 mg?L-1 BCJB01 soluble powder (62.65%).The results showed that alternate using BCJB01 and BMJBN02 SC or using BCJB01 WP added 0.1% additives,all had good control effects on grape downy mildew,and they were good alternative fungicides to grape downy mildew.
