Abstract:
Taking‘Zhongshu No.4’tomato as material,the control efficacy of Wuyiencin and Bacillus subtilis on tomato gray mould disease in greenhouse were studied,in order to screening efficient bio-pesticides.The results showed that the efficacies of bio-pesticide Bacillus subtilis 250 times dilution and 1% wuyiencin 250 times dilution reached to 54.23% and 52.54% respectively seven days after the first application.Seven days after the second application,the efficacies of Bacillus subtilis 250 times dilution and 1% wuyiencin 250 times dilution had exceeded 60%.Seven days after the third application,the efficacies of bio-pesticide Bacillus subtilis 250 times dilution and 1% wuyiencin 250 times dilution were similar to that of chemical-pesticide 75% chlorothalonil WP 500 times dilution,which were 71.82% and 74.73% respectively.In the whole growth season,pesticides were applied three times and seven days of application interval time was proposed.They were effective preparation for the disease control,and these two biopesticides had a sound prospect for the application in non-pollution vegetables production in greenhouse.
