Controlling Pests and Diseases at Peanut Sowing Time Is Highly Effective
Many types of pests and diseases harm peanuts, they occur over a wide range, and the damage is severe. Because the occurrence, distribution, epidemic patterns, damage periods, and living habits of the various pests and diseases all differ, it is quite difficult to time control measures properly in production. Practice has shown that controlling pests and diseases at sowing time can save part of the major losses peanuts suffer from pests and diseases...
Many types of pests and diseases harm peanuts, they occur over a wide range, and the damage is severe. Because the occurrence, distribution, epidemic patterns, damage periods, and living habits of the various pests and diseases all differ, it is quite difficult to time control measures properly in production. Practice has shown that controlling pests and diseases at sowing time can save part of the major losses peanuts suffer from pests and diseases, and can also serve multiple purposes with a single pesticide, save labor, save time, reduce pollution, and significantly increase peanut yield, raising economic and ecological benefits, achieving twice the result with half the effort. Peanut stem rot (stem rot disease, black mold disease, wilt disease) is one of the main peanut diseases; its occurrence, spread, and expansion are mainly caused by seed-borne fungi, which become the primary infection source of the disease, and infection then spreads and causes damage. When sowing peanuts, mixing seed with a 500-fold dilution of 10% carbendazim wettable powder can basically control the occurrence and damage of this disease. In the early growth stage of peanuts, the crop often suffers damage from aboveground pests such as aphids and thrips and underground pests such as white grubs and wireworms. Aphids and thrips suck peanut leaf sap, causing chlorophyll deficiency, affecting peanut plant growth and development, and at the same time spreading peanut viral disease; white grubs damage peanut roots, stems, and leaves, causing missing plants and affecting peanut growth and development; wireworms damage peanut seeds, young roots, and so on. Selecting agents with strong systemic action, long residual activity, and broad insecticidal spectrum, such as aldicarb, carbofuran, and 812, can effectively control these pests. Because aphids and thrips are effectively controlled, the transmission vectors of peanut viral disease are eliminated, and peanut viral disease is also controlled at the same time. While these agents control the main pests in the peanut seedling stage, they also have an effect on peanut root-knot nematode disease. Usually aldicarb is used at 0.5 kg per mu, or 3% carbofuran granules at 2.5 kg, or 812 powder at 0.6-0.8 kg, covered over the seed when sowing peanuts, with very good results.
