1985年以来,我县对玉米包衣种子进行了连年试验、示范,取得了较好的效果。 1.能防治病虫危害、保苗效果好玉米种子包衣能防治毒病、粘虫及地下害虫等病虫危害。据1986年在永安乡试验,于玉米出苗23天后调查,包衣种子幼苗毒病发病率2%,粘虫危害株率1.7%,而空白对照区的玉米幼苗毒病发病率6%,粘虫危害株率8.7%,分别减轻了4%和7%。用1605农药拌种的玉米毒病发病率2.7%,粘虫危害株率10%。到9月18日调查玉米螟危害情况,包衣种子植株危害
Since 1985, our county has conducted perennial tests on corn-coated seeds to demonstrate and achieve good results. 1. To prevent pests and insect pests, seedlings and good seedling effect Corn seed coating can prevent poisonous diseases, armyworms and underground pests and other pests and diseases hazards. According to the test conducted in Yongan Township in 1986, after 23 days of emergence of maize, the incidence of poisonous seedling disease in seed coating was 2% and that of armyworm was 1.7%, while that of maize seedling in blank control area was 6% Hazard strain rate of 8.7%, respectively, reduced by 4% and 7%. Corn germ with 1605 pesticide seed dressing incidence of 2.7%, 10 strains of armyworm damage. To September 18 to investigate the corn borer damage, coating seed plant hazards
