侧柏毒蛾〔Parocneria furva(LeeK)〕是我省徐州地区侧柏林的重大食叶害虫。我们在1978～1979年通过室内和林间地面试验证明灭幼脲Ⅰ号对侧柏毒蛾具有较高的药效。1980年春结合飞机治虫,进行了飞机喷洒灭幼脲Ⅰ号防治侧柏毒蛾试验,飞机喷洒一架次,面积180亩,取得较好的防治效果。现将结果整理如下。 一、材料和方法 1.药品来源和配制:灭幼脲Ⅰ号由江苏省金坛昆虫激素研究所提供(1980年春合成)。用丙酮作溶剂。每100毫升丙酮中溶解灭幼脲Ⅰ号1克。加入2毫升0212乳化剂(南京钟山化工厂出品)。配制成乳剂备用。 2.喷洒浓度和用药量:运五型飞机装水量为1000公斤。用灭幼脲Ⅰ号280克(用丙酮28000毫升、0212乳化剂560毫升配制)。喷洒浓度为280PPM,喷洒面积为180
Parocneria furva (LeeK)〕 is a major leaf-eating pests in the side Berlin Berlin Xuzhou area. From 1978 to 1979, we tested the indoor and forest ground tests showed that meflopecurde I has the higher efficacy. The spring of 1980, combined with the aircraft pest control, carried out the plane spraying mepivacaine Ⅰ control botany toxicity test, plane spraying an area of 180 acres and achieved better control effect. The results are now organized as follows. I. MATERIALS AND METHODS 1. Source and Formulation of Medicines: Chlorbenzuron No. 1 was provided by the Jintan Insect Hormone Institute of Jiangsu Province (Spring 1980 synthesis). Acetone as a solvent. Dissolution of mefenapam 1 in 100 ml of acetone. Add 2 ml of 0212 emulsifier (produced by Nanjing Zhong Shan Chemical Factory). Prepared as an emulsion backup. 2. Spraying concentration and dosage: Five aircraft loading capacity of 1000 kg. 280 g of mepivacaine I (28000 ml with acetone, 560 ml of 0212 emulsifier). Spray concentration of 280PPM, spraying area of 180
