灭幼脲1号(TH6040)是抑制昆虫几丁质合成的新型杀虫剂。幼虫食下后,脱皮变态受阻而死亡。它具有高效、低毒、低残留、残效期长、对天敌没有明显杀伤等特点。苹掌舟蛾是苹果树食叶害虫。受害叶片残缺不全或仅剩叶柄,严重时全树叶片被吃光,影响果树生长和结果。目前多用滴滴畏、敌百虫等防治,因该虫产生了抗性,用药量大,效果差,成本高。该虫为害盛期正是苹果结果期,巨毒高效杀虫剂不能使用。因此我们于1981年做了灭幼脲1号防治苹掌舟蛾试验。
Chlorpyrifos 1 (TH6040) is a new insecticide that inhibits the synthesis of insect chitin. After the larvae have eaten, the peeled perineum is blocked and dies. It has high efficiency, low toxicity, low residue, long residual period, no obvious killing of other natural enemies and other characteristics. Apple caterpillars are apple tree leaf pests. Injured leaves incomplete or petiole incomplete leaves, severe whole tree leaves are eaten, affecting the growth and results of fruit trees. The current use of dauphinus, trichlorfon and other prevention and control, due to the insects have resistance, dosage, poor results, high cost. The pest damage period is the apple fruit period, giant poison efficient insecticide can not be used. Therefore, we did in 1981, MBP No. 1 prevention and treatment of apple palms moth test.
