摘要
通过田间试验，不同含量苦参碱大豆微粉种衣剂对大豆的病虫害有较好的效果，含0．5％～1．0％苦参碱的微粉种衣剂的效果与目前应用的30％克多福悬浮剂型大豆种衣剂效果相当，根腐病防治效果在58%左右，2．5％苦参碱微粉种衣剂的效果为64％；0．5％～2．5％苦参碱微粉种衣剂防治潜叶蝇的效果在73．1％--95％，蛴螬的防治效果在71．4％～100％，包囊线虫的防治效果在94．9％～98．6％，优于悬浮剂30％克多福大豆种衣剂。
The results of field trail indicated that matrine soybean seed coating agent had good control effect to the soybean pest and diseases. The effect of 0. 5%-1% matrine FD seed dressing agent to soybean rootrot was about 58%, almost the same as the effect of 30% carbofuran carbendazim thiram WS, and the effect of 2.5% matrine was 64%. The study showed that 0. 5% -2.5% matrine seed coating agent provide better control to soybean root miner, grub and soybean cyst nematide compare to the 30% carbofuran carbendazim thiram WS, the effect was 73.1% -95% ,71.4%-100% and 94.9%-98.6% respectively.
