Prevent peanuts and horses in advance

Peanut thrips are a common pest in peanut production, especially in high temperature and drought conditions. The insect uses the adult nymph and the nymph to suck the heart and the main axis of the peanut, causing the heart leaf and the main axis to be twisted and forming a sore-like shape. When the insect is severe, the whole plant is curled up and dead. Continued high temperature and drought will increase the trend of the pest. To this end, farmers should be reminded to pay great attention to strengthen field control, control peanuts and horses in the initial stage, and prevent outbreaks, resulting in a large area of ​​peanut production. The commonly used control methods in production are based on chemical control, using 7.5% rotenone + fenvalerate emulsifiable concentrate, spraying 10 to 20 ml of water with 40 kg of water, or 4.5% beta-cypermethrin emulsifiable concentrate 1000 times and 10% imidacloprid. Wettable powder 1000 times liquid to 40 kg spray control. At the same time, in the peanut flowering period, it is necessary to strengthen the management of water and fertilizer, and prevent the phenomenon of water shortage and lack of fertilizer in the prevention and treatment of the plot. The thin plots and the weak growth of the plants will cause serious occurrence of peanut thrips. Therefore, field management should be strengthened as early as possible. Cultivate strong seedlings, enhance resistance and reduce the incidence of pests. (Wang Hu)
