水稻跗线螨防治技术研究

Study on Control Technology Against Steneotarsonemus sp. in Rice

近年以来,水稻跗线螨在珠三角地区特别是晚稻上的发生越来越严重。通过试验发现:广东省农业科学研究院生产的虫螨净对于跗线螨防治效果比较明显,可以用于水稻跗线螨的防治。跗线螨的防治必须做好预测预报,最佳防治时期为拔秆期和破口期2次用药。

The damage of Steneotarsonemus sp. in rice increasingly affects rice cultivation in the Pearl River region especially in late season.In present study,we found that the pesticide Chongmangjing produced by Guangdong Academy of Agricultural Sciences significantly had good control effect on Steneotarsonemus sp. and could be utilized in practice.The best period for utilizing Chongmangjing was on the pull stem and rupturing stage, while the forecasting occurrence of Steneotarsonemus sp. was also critical.
