蛴螬取食萌发种子和残存种皮是药剂拌种杀虫保苗的生物学依据。应用高效低毒低残留农药——辛硫磷拌种,可以逐步取代当前常用的高残留、剧毒类农药.改变目前防治现状。 应用种子上有效含量0.0375％的辛硫磷拌种,保苗效果稳定在90％以上,在土壤中残效时间为25天,且对小麦、玉米、高梁等作物无药害表现。经47万余亩麦田示范应用,一致表现药效稳定,人畜安全。 拌种还可兼治蝼蛄,惟后期出现死苗,保苗效果稍差。采用拌种加颗粒剂方法,可以提高早春和秋播拌种的药效。
Emus feeding on germinating seeds and remaining seed coat is the biological basis of seed dressing insecticide seedlings. Application of high efficiency and low toxicity low residual pesticide - phoxim seed dressing, you can gradually replace the current commonly used high residue, highly toxic pesticides to change the current status of prevention and treatment. Applying phoxim seed dressing with the effective content of 0.0375% on seed, the seedling keeping effect is stable at above 90%, the residual effect time in the soil is 25 days, and no injury to crops such as wheat, corn and sorghum. After more than 470000 acres of wheat field demonstration application, the consistent performance of stable efficacy, human and animal safety. Seed dressing can also cure 蝼 蛄, but the late emergence of dead seedlings, seedlings less effective. The use of seed dressing and dressing methods, can improve the early spring and autumn planting the efficacy of the seed.
