Peanut planting in autumn to control diseases and insect pests

The main diseases of peanut are leaf spot and rust, leaf spot should be sprayed to prevent and control the disease in time at the initial stage of the disease, choose 75% chlorothalonil + 70% thiothalonil 1000 times 1500 times liquid, or 30% copper oxychloride + 75% chlorothalonil 1000 times liquid spray 2 times 3 times, once every 10 to 15 days, use alternately and spray evenly. To strengthen the prediction of rust, the lower leaves of the plant should be regularly checked at the early flowering stage and sprayed in time to control the disease. 50% triadimefon sulfuric acid suspension 1000: 1500 times, or 30% copper oxychloride + 75% chlorothalonil 1000 times solution spray control 2 times 3 times, once every 7 to 15 days, use alternately. If peanuts appear physiological yellow dwarf phenomenon, each 50 grams of magnesium sulfate, zinc sulfate and copper sulfate, 100 grams of borax, 250 grams of urea and 1 branch of phytoprotegerin can be used per mu, dissolved in 60 kg of water, sprayed once every 7 days, and sprayed continuously for 3 times.

The main pests of peanuts are peanut thrips, aphids, leaf rollers, Spodoptera litura and so on. Once the harm of thrips and aphids is found, spray control should be timely selected, such as 2.5% Kungfu EC 2000 times or 50% Cologne EC 1000 times (or both), 48% Lesbon EC 1000 times, 25% Aktai water dispersible granules 5000 times and so on. Leaf rollers and Spodoptera litura should be controlled in the early stage of low instar larvae (before the 3rd instar). The available medicaments are 2.5% Kung Fu EC 2000 times or 50% Cologne EC 1000 times (or both), 10% suspension 1000 times, 20% Miman suspension 1000 times, 48% Lesbon EC 1000 times, 5% Yitaibao EC 800x and so on.

Pay attention to rodent control during peanut ripening. Diphacinone sodium salt and bromine poison bait were placed around the planting area, and obvious warning signs were set up to ensure the safety of human beings and animals.
