1979年,我们在双季晚稻上,进行了呋喃丹、杀虫脒一次浅层施用防治稻飞虱(主要是褐稻虱)的试验。一、供试农药3％呋喃丹颗粒剂(进口);25％杀虫脒水剂(浙江龙游化工厂生产)。二、试验方法将3％呋喃丹颗粒剂、25％杀虫脒水剂分别以1:5、1:40与细干沙泥混和并加少量水制成“捏成团、撒得开”的毒土。于双季晚稻插后第二次耘田(插秧后20天,即8月19日)前,排去田水,将药土均匀撒下,当天耘田一次,田水自然落干,然后再灌水。每亩用药量,呋喃丹区用3％颗粒剂6
In 1979, we conducted a trial of carbofuran and chlordimeform superficial applications on planthoppers (mainly brown planthopper) on double crop late rice. First, the test pesticide 3% carbofuran granules (imported); 25% Chlordimeform agent (Zhejiang Longyou chemical plant production). Second, the test method 3% carbofuran granule, 25% pesticidal amidine amidine agent respectively 1: 5, 1:40 with fine dry sand mixed with a small amount of water made of “pinch into a group, sprinkle open” Toxic soil. In the double season late rice inserted after the second Yun Tian (20 days after transplanting, that is, August 19), drain field water, the soil evenly sprinkle down, the same day Yun Tian, natural water dry, and then Irrigation. Amount per acre, carbofuran area with 3% granules 6
