地老虎是我省烟区苗期及移栽烟苗的主要害虫之一.主要是小地老虎为害,移栽烟草被害率一般在8%左右,为害严重时可达25%以上.常造成断苗、缺株,严重影响烟叶产量与品质.近几年,我们曾先后选用一批高效、低毒、低残留农药,其中以辛硫磷效果较佳.75%辛硫磷乳剂(天津农药厂、上海农药厂生产)为高效、低毒、低残留广谱性杀虫剂,可用于水稻、蔬菜、果树、茶叶、烟草等作物吃叶害虫或地下害虫的防治.辛硫磷对人畜毒性很低,对害虫有触杀、胃毒作用,防治效果很好.在作物叶上喷雾的残效期3～4天;在土壤中残效期为1～2个月.
Tigers is one of the main pests in the tobacco seedling stage and transplanted tobacco seedlings in our province, which is mainly caused by the small Tigers, and the damage rate of transplanting tobacco is generally about 8%, and when the damage is serious, up to 25% In recent years, we have successively selected a group of high efficiency, low toxicity, low residue pesticides, of which the phoxim effect is better .75% Phoxim (Tianjin Pesticide Factory , Shanghai Pesticide Factory production) is a high efficiency, low toxicity, low residual broad-spectrum insecticide, can be used for rice pests, vegetables, fruit trees, tea, tobacco and other crop pests or underground pest control. Low, the pests have contact, stomach poisoning, control effect is very good. In the crop leaf spray residual validity of 3 to 4 days; in the soil residual validity of 1 to 2 months.
