稻瘿蚊在我县间歇性暴发成灾,严重影响中、晚稻生产。目前化学防治仍是主要手段之一。为了探寻益舒宝不同用量防治稻瘿蚊效果,1993年晚季在我县下坝乡进行该项试验。试验处理设10％益舒宝颗粒剂(广东英红华侨农药厂生产)l公斤/亩、1.25公斤/亩、1.5公斤/亩,3％甲基异柳磷颗粒剂(福建福安农药厂生产)3.25公斤/亩,3％呋喃丹颗粒剂(福建福安农药厂生产)3公斤/亩,以不施药为空白对照。6个处理随机区组排列,3次重复,每小区面积0.03亩,小区间作小田埂,于水稻移栽后3天(8月1日)以每亩用药量拌细砂30公斤撒施。待对照区充分长出标 Rice gall midge intermittently outbreaks in our county, seriously affecting the production of late rice. At present, chemical control is still one of the main means. In order to explore the different dosage of Yishuobao control the effect of rice gall midge, the late 1993 in Xia County, my county for the test. Experimental treatment 10% Yishuobao granules (Guangdong Honghua Pesticide Factory production) l kg / mu, 1.25 kg / mu, 1.5 kg / acre, 3% methyl isofenan granules (Fujian Fuan Pesticide Factory production) 3.25 kg / mu, 3% carbofuran granules (Fujian Fuan Pesticide Factory production) 3 kg / mu, to not spraying as a blank control. 6 treatments were arranged in random blocks and repeated 3 times. The area of ​​each plot was 0.03 mu. The small area was used as a small ridge ridge. After the rice was transplanted for 3 days (August 1), 30 kg of fine sand was added per acre. To be fully controlled area out standard
