How to Prevent Pests in the Early Autumn Festival
Insect pests are serious in the early fall season. If management fails to keep up, quality can be easily reduced and yields reduced. In the early fall season, pest control measures should be based on agricultural control, with both physical and chemical control. So how to control pests in the early fall season? In the early autumn season, take care to prevent the following three insects.
Soybean meal
Every year from June to October, soybean meal is the larvae damage period. Adults have phototaxis, eggs scattered in the tender horn, flowers and petioles, the newly hatched larvae into the tender horn or flower feeding, resulting in flowers, horns off. Older larvae feed into the beans, and the beans are often rotted after the rain. The larvae have the habit of nocturnal emission and backlighting, hiding in the flower, beans, or leaf blades during the day, and excreting insect feces to plug the boreholes. In spite of sporadic outbreaks during the rainy days and during the day, climbing out of the wormholes is generally started in the evening and the activities are terminated in the early morning of the next day.
Its prevention measures are:
1. Clear the falling corner of the field and remove the wounded leaves and beans to reduce the source of insects.
2. Set up black light lamps, use adult phototaxis habits, and seduce and kill.
3. The agent is selected from fluoroflumne 2,000 times solution or 40% fenvalerate 6000 times solution, 2.5% deltamethrin 3000 times solution and sprayed once every 10 days.
How to prevent insects in the early autumn season
Leaffly
The larvae invade the leaves and damage them. The leaves of the larvae only leave the upper and lower epidermis to form a tortuous tunnel and affect plant growth. Leaf miners mainly damage peas, beans, cowpeas, cabbage, broccoli, cabbage, rapeseed, radish, lettuce, tomatoes, eggplant, and potatoes.
Its prevention measures are:
1. Use adult armyworm traps to kill adult insects.
2. Adults lay their eggs on the back of the leaf, spraying the liquid on the back of the leaf. At the beginning of larvae damage, insecticides with both internal absorption and contact toxicity were selected, such as 48% chlorpyrifos EC 800 to 1000 times, and sprayed 2 to 3 times continuously.
Red spider
The red spider on the beans is also known as the bean leafhopper. The period from August to September is the period of prosperous growth, and if the leaves are ingested by the nymphs and raccoons, the leaves will be crushed after being damaged. In the early stage of development, the leaves lose their green color and become red and white, and the thin wire mesh on the back of the leaf can directly recognize the range and area of ​​occurrence. Immediately after the occurrence of a pesticide spray ring sprayer, the scope of the scope of the accident is slightly greater than the scope, then the plants in the encircled circle thoroughly sprayed to prevent the spread of spider mites.
Its prevention measures are:
1. Pay attention to the monitoring of pests and find that there are a small number of victims. The insect leaves should be promptly removed and burned. In case of drought, timely irrigation and fertilization should be paid attention to, so as to promote plant growth and inhibit the proliferation of leafhoppers.
2. The use of selective acaricides for general treatment was carried out before the scab phase and after the soybean meal was harvested, with the focus on uniform spraying on the back of the leaves. Can be sprayed with 20% compound Liuyangmycin EC 1000 times solution or 1.8% avermectin EC 1500~2000 times solution, 15% Phlegm EC 3000 times solution, and 20% amitraz EC 2000 times solution. Pay attention to rotating medications and promote the use of highly effective and less toxic biological pesticides.
Food additive is a chemical substance added in the food production process to improve the quality, taste, color, freshness and other characteristics of food.
