近年来,稻螟蛉在苏北沿海地区重发频率明显提高,一般药剂防治效果并不理想,不同程度地影响了水稻生产。试验结果表明,2.5%高效氯氟氰菊酯EC、5%氟虫腈SC和90%杀虫单WP等药剂,对稻螟蛉具有较好防治效果,其中,2.5%高效氯氟氰菊酯EC治虫效果尤为突出,在生产上应用后,取得了十分显著的控害保苗效果。 In recent years, rice borer in the coastal areas of northern Jiangsu significantly increased the frequency of recurrence, the general effect of control agents are not ideal, to varying degrees, affecting rice production. The results showed that 2.5% lambda-cyhalothrin EC, 5% fipronil SC and 90% insecticidal single-WP and other agents have a good control effect on rice stem borers, of which 2.5% lambda-cyhalothrin EC Pest control effect is particularly prominent, after the application of the production, made a very significant control seedling protection effect.
