Good control effect of diseases and insect pests during peanut sowing

There are many kinds of diseases and insect pests that harm peanut, the occurrence range is wide, and the harm is serious. Due to the differences in the occurrence, distribution, epidemic law, harm period and living habits of all kinds of diseases and insect pests, it is difficult to control them in the right time in production. The practice shows that the prevention and control of diseases and insect pests during sowing can save some of the great losses caused by peanut diseases and insect pests, and can play the role of multi-use of one medicine, labor-saving, time-saving, reducing pollution, significantly increase peanut yield and improve economic and ecological benefits. get twice the result with half the effort. Peanut inverted seedling disease (stem rot, black mold, Fusarium wilt) is one of the main diseases of peanut, which occurs, spreads and spreads. When sowing peanut seeds with 500 times solution of 10% carbendazim wettable powder can basically control the occurrence and harm of the disease. In the early growth stage, peanuts are often harmed by aboveground pests, aphids, thrips, underground pests grubs, golden needles and so on. Aphids and thrips suck peanut leaf juice, resulting in chlorophyll deficiency, affecting peanut plant growth and development, and spreading peanut virus disease; grubs harm peanut roots. Stems and leaves cause lack of peanut seedlings and affect the growth and development of peanuts; golden needle insects harm peanut seeds and young roots. Selecting insecticides such as aldicarb, carbofuran and 8l2, which have strong internal absorption, long duration and wide insecticidal range, can effectively control these insect pests. Due to the effective control of aphids and thrips, the transmission vector of peanut virus disease was eliminated and peanut virus disease was cured. These insecticides not only control the main pests in peanut seedling stage, but also play a role in the control of peanut root-knot nematode disease. Usually use aldicarb 0.5 kg per mu, or 3% furan granule 2.5 kg, or 812 powder 0.6 ml 0.8 kg, cover seeds when peanuts are sown, the effect is very good.
