摘要
本文利用市场上5种防治蚜虫的杀虫剂测定燕麦生长期防治蚜虫的安全有效用药浓度,为燕麦田蚜虫的药剂防治提出合理用药建议。结果表明:25%烯啶虫胺SP+25%噻虫嗪WG、30%唑虫酰胺SC、25%抗蚜威WG、32000IU/mg苏云金杆菌WP、10%吡虫啉WP在试验浓度下对燕麦安全。建议在蚜虫发生较严重,或者已出现传播红叶病(病毒病)的现象时,选用30%唑虫酰胺SC、10%吡虫啉WP等化学药剂防治。若收割期前15 d内蚜虫发生较轻,建议使用安全性更高的苏云金杆菌进行防治,或者利用田间自然天敌进行生物控制。
In this thesis,five kinds of market-insecticides for controlling aphids are used to determine the safe and effective concentration of aphids in the oat growing period,through which reasonable insecticide suggestions are proposed for the prevention and control of aphids in oat fields.The results shows that the test concentration is safe to oats with 25%Nitenpyram SP+25%Thiamethoxam WG,30%Tolfenpyrad SC,25%Pirimicarb WG,32000 IU/mg Bacillus thuringiensis WP and 10%Imidacloprid WP.30%tolfenpyrad SC,10%imidacloprid WP are suggested to be used for control when aphids are serious or when red leaf disease(viral disease)has appeared.If it is relatively light for the occurrence of aphids within 15 days before the harvest period,the safer agritol is recommended to be use for control,or natural enemies in the field are to be used for biological control.
