小麦苗期是多种病虫草害防治的关键时期,通过近日麦田病虫基数调查,地下害虫一般0.9/平米,土传病害的病株率一般在5%左右,禾本科杂草一般1—3株/平米,最高21株/平米,阔叶杂草一般2—5株/平米,最高56株/平米。做好此时期的防治工作,不仅可以控制麦田早期病虫草的发生危害,而且对于中后期小麦病虫害也有明显抑制作用,能够起到事半功倍的效果。一、地下害虫危害初期亩用5%辛硫磷颗粒剂2公斤,拌细土30—40公斤撒施或亩用50%辛硫磷乳油
Wheat seedling stage is a key period for the prevention and control of various diseases, pests and weeds. Through the recent investigation on pest and disease resistance in wheat fields, the average number of underground pests is 0.9 / m2. The rate of diseased plants in soil is generally about 5%. The weeds are generally 1-3 Strain / square meter, the highest 21 / square meters, broad-leaved weeds generally 2-5 / square meters, the highest 56 / square meter. Doing a good job in this period of prevention and control work, not only can control the early occurrence of wheat and insect pests hazards, but also for the late wheat pests and diseases also have a significant inhibitory effect, can play a multiplier effect. First, the damage of underground pests early mu with 5% phoxim granules 2 kg, mix fine soil 30-40 kg spreading or mu with 50% phoxim EC
