【摘要】In this experiment, five insecticides with different insecticidal mechanisms with high efficiency and low toxicity were selected for the field efficacy test of Spodoptera exigua on lettuce. The results showed that the five insecticides used in the experiment had certain control effect on Spodoptera exigua on lettuce. One day after the treatment, the control effect of the five pesticides reached the highest level, meaning that they all can kill pests quickly. Seven days after the treatment, three of them, 200 g/L chlorantraniliprole SC, 10.5% trifluoromethane EC and 30 billion PIB/g Spodoptera exigua Nucleopolyhedrosis virus WG, were still doing well with more than 89% control effect, and even had no adverse effect on lettuce.
