| Abstract: | To effectively control cassava important soil insect pests in Bulang mountain area of Yunnan province, control effect of soaking the stems with harmless insecticides on cassava soil insect pests was conducted. The results showed that, soaking the stems with the water mixture of 48% chlorpyrifos EC 1 000 times and 1.8% abamectin EC 2 000 times for 5 min and 10 min were the most effective for cassava planting. the average germination rates significantly increased to 96.5% and 97.0% from 62.5% of non-treatment and 75.0% and 75.6% of water treatments, respectively; the average pest rates significantly decreased to 6.3% and 5.5% from 56.8% of non-treatment and 45.0% and 44.8% of water treatments, respectively; the average yields significantly increased to 2 113.3 kg/667 m2 and 2 135.2 kg/667 m2 from 1 112.5 kg/667 m2 of non-treatment and 1 376.5 kg/667 m2 and 1 393.3 kg/667 m2 of water treatments, respectively. The results above indicated that soaking stems would not noly significantly decrease the pest rate, but also significantly increase the germination rate and yield, which will support the steady and sustainable development of cassava industry in Bulang mountain area of Yunnan province. |
