不同药剂对樱桃番茄3种主要病虫害的防控效果评价

Evaluation of Control Effect of Different Fungicides on Three Main Diseases and Insect Pests of Cherry Tomato

为了筛选出有效防治樱桃番茄灰霉病、青枯病、烟粉虱的药剂,研究了不同药剂对樱桃番茄这3种主要病虫害的药剂的防控效果。试验结果,表明复配药剂30%啶酰菌胺·咯菌腈SC 0.08g/m^(2)对樱桃番茄灰霉病发防控效果最好,末次药后7d对叶片和果实的防效分别达到83.96%和85.89%;50%啶酰菌胺WG 0.08g/m^(2)和50%腐霉利WP 0.15g/m^(2)对番茄灰霉病的防效也均高于78.00%,对樱桃番茄灰霉病表现了较好的防控效果。22.4%螺虫乙酯WP 0.05mL/m^(2)樱桃番茄烟粉虱防控效果最好,药后7d防效达83.38%,其次为50g/L双丙环虫酯DC 0.02mL/m^(2),防效为80.03%。生防菌剂50亿CFU/g多粘类芽孢杆菌0.3g/m^(2)对樱桃番茄青枯病的防效较好,防效为53.51%。本研究筛选出了对樱桃番茄灰霉病、青枯病和烟粉虱具有较好防控效果的的药剂,对樱桃番茄生产具有重要的指导意义。

The control effects of different fungicides on Botrytis cinerea,Bacterial wilt and Bemisia tabaci were studied in this paper in order to screen effective fungicides against main diseases and insect pests of cherry tomato.The results showed that the control effect of Botrytis cinerea on cherry tomato with the compound of 30%boscalid•fludioxonil SC 0.08g/m^(2) was the best,after 7 days of the last administration,whose control effects on leaves and fruits were 83.96%and 85.89%respectively.And the control effects of 50%acetanilide WG 0.08g/m^(2) were 80.06%and 83.67%respectively,while the control effects of 50%Pythil WP 0.15 g/m^(2) were 79.70%and 78.90%respectively.22.4%Spirotetramat WP 0.05mL/m^(2) had the best control effect on Bemisia tabaci,with the control effect reaching 83.38%after 7 days of the last administration,followed by 50 g/L dicycloproxylate DC 0.02 mL/m^(2),with the control effect reaching 80.03%.The solution of 5 billion CFU/g of Paenibacillus polymyxa had the highest control effect on bacterial wilt of cherry tomato,which was 53.51%.The results showed that the fungicides with good control effect on Botrytis cinerea,Bacterial wilt and Bemisia tabaci of cherry tomato were screened,which had important guiding significance for the main pest control of cherry tomato.
