摘要
以"中蔬四号"番茄为试材,研究了武夷霉素和枯草芽孢杆菌对温室番茄灰霉病的防治效果,以期筛选有效的防治温室番茄灰霉病生物制剂。结果表明:第1次施药7d后,枯草芽孢杆菌250倍液和1%武夷霉素水剂250倍液对番茄灰霉病的防治效果分别为54.23%和52.54%;第2次施药7d后,枯草芽孢杆菌250倍液和1%武夷霉素水剂250倍液对番茄灰霉病的防治效果均达60%左右;第3次施药7d后,枯草芽孢杆菌250倍液和1%武夷霉素水剂250倍液对番茄灰霉病的防治效果可分别达到74.73%和71.82%,与化学药剂75%百菌清500倍液的效果相当。在整个生长季,共施药3次,建议每次用药间隔为7d。试验结果表明,枯草芽孢杆菌和1%武夷霉素水剂是该病害的有效防治制剂,在蔬菜无公害生产中具有良好的推广应用前景。
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.
