近年来,5％甲拌磷颗粒剂随种条播法在防治我省油菜苗(苔)期主要害虫跳甲类(Phy llotreta spp·Psy lliodes spp.)和油菜茎龟象(Ceuthorrhynchus sp.)的试验示范及大田应用中,都显示了优良的治虫保苗促增产效果。一法多治,简便易行,经济效益高,应用前景广阔。甲拌磷杀虫剂本身兼具触杀、熏蒸和胃毒(包括植物内吸后使害虫胃毒)三种杀虫性能。使用甲拌磷的5％颗粒剂,以随种条播法播施杀虫,何种性能起了主要作用?这一问题以前未搞清。本研究采取田间模拟与室内局部控制相结合的办法进行,获得了比较满意的结果,有助于解释这一问题。
In recent years, 5% phorate particles with seed sowing in the prevention and treatment of rapeseed (moss) of our province pest class aphids (Phyllotreta spp · Psy lliodes spp.) And rape stem turtle (Ceuthorrhynchus sp.) Test Demonstration and field applications, have shown that good pest control seedlings to promote production. Multi-treatment method, simple and easy, high economic efficiency, broad application prospects. Phorate pesticide itself both touch, fumigation and stomach poisoning (including the absorption of plant pests stomach poisoning) three insecticidal properties. The use of phorate phorate 5% granules to sow the seeds with sowing and insecticides, which performance has played a major role? This problem has not been previously clear. In this study, field simulation and indoor local control were combined to obtain satisfactory results, which could help to explain this problem.
