近年来,小麦吸浆虫在陕西、安徽等省急剧回升,损失严重。为了寻找替代“六六六”的新农药品种,探求小麦吸浆虫防治新技术,陕西、安徽等省植保部门作了大量试验研究工作,开发出多种防治新技术。目前生产上应用的有毒土法、喷粉法等,分别介绍如下: 一、毒土法 (一)敌马粉毒土法。于5月中下旬,亩用4％敌马粉剂1.5—2公斤,掺入20公斤细潮土,拌匀后撒施。用药一次,防效80％左右。 (二)甲基异柳磷毒土法。亩用2％甲基异柳磷粉剂2—3公斤,或3％甲基异柳磷颗粒剂1.5—2公斤,掺入30公斤细潮土内拌匀,于 In recent years, wheat midge in Shaanxi, Anhui and other provinces rose sharply, the loss was serious. In order to find a new pesticide alternative to “666” and to explore new technologies for control of the midge of wheat, Shaanxi, Anhui and other provincial plant protection departments have made a great deal of experimental research and developed a variety of new prevention and treatment technologies. At present, the production of toxic soil method, dusting method, respectively, are described below: First, the poison soil method (A) of the enemy horse powder poison soil method. In late May, mu with 4% enemy horse powder 1.5-2 kilograms, mixed with 20 kilograms of fine Chao soil, mix and spread. Medication once, about 80% control effect. (B) methyl isofenphos poison soil method. Mu 2-3 kg per acre with 2% methyl isofenphos powder, or 1.5-2 kg 3% methyl isofenphos granules, mix in 30 kg of fine tide soil and mix well in
