摘要：

为明确当前主流农药对浙北稻区二化螟的防治效果,筛选科学防控二化螟的高效药剂,本研究在早稻上开展了二化螟药效试验。结果表明:在新品种上,环丙氟虫胺的保苗效果达到95.64%,防治效果为92.17%。在早稻中组18上,阿维·甲虫肼的保苗效果为98.11%,乙多·甲氧虫和氯虫苯甲酰胺(225 mL·hm-2)的保苗效果接近,阿维·甲虫肼和乙多·甲氧虫的防治效果均达到95.00%,明显高于氯虫苯甲酰胺的防治效果。在早稻甬籼15上,四唑虫酰胺+阿维菌素处理下的保苗和防治效果均为最高,分别达到96.30%和94.44%。在苏云金杆菌处理下,甬籼15上的每百丛二化螟寄生蜂的蜂茧量最高,达到1.00。由此得出,当前浙北地区早稻二化螟的应急防控可供推荐的药剂或药剂组合有:乙多·甲氧虫、阿维·甲虫肼、四唑虫酰胺+阿维菌素,而环丙氟虫胺则可作为潜在备选药剂,在卵孵高峰期首次用药,7~10 d后再次用药以确保防效。

Abstract:

In order to clarify the control effect of current mainstream pesticides on Chilo suppressalis (Walker) in early rice in northern Zhejiang, and to screen efficient pesticides for scientific control of Chilo suppressalis (Walker), pesticide efficacy experiments were conducted on early rice. The results showed that the seedling protection effect of cyproflanilide reached 95.64% and the control effect was 92.17% in the new variety. On the early rice variety Zhongzu 18, the seedling protection effect of avermectin-methoxyfenoz was 98.11%, and the seedling protection effects of spinetoram·methoxyfenozide and chlorantraniliprole were similar. The control effects of avermectin-methoxyfenoz and Spinetoram·Methoxyfenozide both reached 95.00%, higher than Chlorantraniliprole (85.00%). On the early rice variety Yongxian 15, the treatment with tetraniliprole+abamectin had the highest seedling protection and pest control effects, reaching 96.30% and 94.44%, respectively. Under the treatment of Bacillus thuringiensis, the number of cocoons of the first generation of parasitic wasps caused by Chilo suppressalis (Walker) on Yongxian 15 was the highest, reaching 1 per hundred clusters. Thus, the recommended chemicals or combinations for the emergency control of Chilo suppressalis (Walker) in early rice in northern Zhejiang are spinetoram·methoxyfenozide, avermectin-methoxyfenoz, tetraniliprole+abamectin. And cyproflanilide can be used as a potential alternative agent, which should be administered for the first time during the peak period of egg incubation, and then applied again on 7 to 10 days later to ensure the control effect.
