蚜虱净浸种对水稻苗期害虫控制效果初探

Preliminary Exploration into Effect of Application of Yashijing on Prevention and Control of Insects

本文介绍了应用10%蚜虱净1000、2000、4000倍液浸种对水稻苗期害虫控制效果和安全性。试验结果表明:用10%蚜虱净浸种,不但使用方便,而且能较长时间有效地控制水稻苗期的主要害虫如稻飞虱、稻蓟马、稻蝗等,有利于减少用药次数,节约用工,避免环境污染;尤其对白背飞虱的控制能有效地切断条纹叶枯病的毒源,达到治虫防病的目的,确保水稻前期正常生长。

Effect and safety of use of 10% Yashijing respectively mixing with 1000, 2000 and 4000 times of water to wet paddy rice seed is introduced in this paper. The result of experiment indicated that the use of 10% Yashijing was not only convenient but was also able be effectively and efficiently to prevented and controlled pests like Sogatella furcifera, Stenchaetothrips biformis and Oxya chi- nensis during the period of growth of paddy rice seedling for a long time. It could decrease the amount of use of Yashijing, saved labors and avoided environmental pollution, especially prevented Sogatella furcifera effectively and effMently so that it can control occurrence of Laodelphax striatellus,resulted in desirable effect and ensured normal growth of paddy rice at the preliminary stage.
