Peanut is the main economic crop in China and is grown in all regions of China. Recently, some growers have responded that there are many small green worms on the peanuts. The growers said that there were fewer small green worms on the peanuts last year. This year, there are more. Why do the small green worms on the peanuts increase gradually? The growers say they don’t know why. ?Here we take a look!

What is the hazard of small green worms in peanut planting?

Many growers think that after the needle-cut period has passed, the green worms will basically not have to go through the tube, because the main bottom has already begun to enter the pod-forming period and the fruit-expanding period. In fact, the idea is wrong, because the fruit grows after the peanut results. The nutrients that need to be supplied through the leaves do not mean that the nutrients of the soil can be absorbed in the soil without any light, mainly relying on the photosynthesis of the leaves, the photosynthesis of the leaves during the day, and the accumulation of dry matter by the peanuts at night. Play a role as a Pengguo. If the worms eat the leaves, the photosynthesis will be reduced, which will definitely affect the final yield of the peanuts.

In addition, there will be red spiders. It is best to use the drugs that control the red spiders when they are found to be in contact with the spiders, so as to prevent the loss of the growers. How to use pesticides for prevention and control?

In the use of pesticides, we can use high-efficiency biperfluthate + chlorantraniliprole + avermectin, these three pesticides to be compounded, and then sprayed once to prevent green insects and red spiders.

The best time to control the use of small insects

Pay attention to the time of fight, because the weather is hot now, it can reach 36 degrees in the morning to noon. When the weather is hot, the worm will run to the back of the peanut leaves, so I will go to the pesticide at this time. It is difficult to prevent and control the green worms, so we need to choose the time to fight drugs. Before 7:00 am, after 6 pm, do not go to 9:00 in the morning, because the sun is coming out earlier, the temperature rises faster, and the peanuts after 6 o'clock. After the leaves have been dried for a day, they have been closed. After the closure, the pesticides we sprayed are easy to hit all parts of the peanuts, so this time the effect is better.

Planting peanuts, the most important thing is the yield problem. These small green worms, red spiders, etc., will affect the growth of peanuts, thereby reducing the yield of peanuts. Therefore, for these small things, don't think it doesn't matter, you must take preventive measures. In addition to pest prevention, peanut field management should also be done to ensure peanut yield and other issues. I hope that the content introduced by Xiaobian can help the majority of growers.
