There are red spider mites on the carob leaves. Some of the leaves are rolled up. How to treat them?

Red spider mites are a kind of mite that is more powerful than honey bugs. If not treated in time when discovered, the leaves of some plants will roll up or even fall off. This kind of red spider is very small, less than 1 mm in length. It is difficult to see with the eyes. It looks like there are red spots. I don’t know what they are? It is Starscream. This type of spider mite reproduces at the fastest speed, reaching more than 100,000 generations a year. It reproduces in hot and dry climates and seriously harms plants. One generation can be completed in 3 to 4 days. The generations overlap on the leaves or on the back of the leaves. It is very disgusting. If you find this situation, it is difficult to control. It is best to pick off the serious leaves and burn them.

Methods to prevent and control spider mites on carob leaves: Spider mites are pests with sucking mouthparts. During the pesticide control process, it is advisable to choose pesticides that are systemic, fumigating, and contact-killing, and are required to be highly efficient and low-toxic. Kills adults, nymphs, eggs and other forms of insects. Such as pyrethroids, copper preparations (but not for long-term use), dicofol, rotenia, pine needle laundry detergent mixture, ovopyrazole anthracene oil emulsion, purple (machine) oil emulsion, lime sulfur mixture, pine needle alkali mixture, etc. ?

1. If there are red spider mites on the bean leaves in your own vegetable garden, and the disease is not widespread, it is recommended to manually remove the diseased leaves to prevent infection and remove the remaining weed leaves in the garden.

2. Red spider mites are a kind of mite with strong disease resistance. The time for spraying liquid is generally in the evening when the weather is not hot. Spray with pyridaben mixed with water and spray evenly on the surface and back of the leaves; spray again after 5 to 7 days to ensure the elimination of spider mites.

3. Mix medications alternately. Do not use one pesticide continuously for a long time. Different pesticides should be used alternately or multiple pesticides should be mixed to prevent pest resistance, give full play to the effect of pesticide application, and improve the economic benefits of prevention and control.

4. Continuous medication. Generations of spider mites overlap, offspring live together, and eggs, nymphs, and adults coexist. Therefore, continuous spraying is required during the major outbreak period, once every 5 to 7 days. Only by spraying 2 to 3 times continuously can the damage be effectively controlled.

5. Spray carefully. Red spider mites avoid light and are mostly distributed on branches, leaves, flowers and fruits, especially on the dark side. Therefore, spraying pesticides must be careful and thoughtful, covering both the yin and yang sides, the top and bottom of the crown, and the inside and outside of the tree. Prevent pests from slipping through the net, improve lethality, etc. There are small yellow dots the size of a pinhead on the front, which are relatively dense, but there is no opening. There are tiny webs and tiny spiders on the back. High temperature and drought have serious spider mite occurrences. You can spray abamectin to prevent and control it. ?

Summary: In early spring, pay attention to clearing litter and weeds inside and outside the field to reduce the source of insects. Pay attention to monitoring the insect situation. If a small amount of damage is found, the insect leaves should be removed and burned in time. In case of drought, timely irrigation and fertilization should be paid attention to to promote plant growth and inhibit the proliferation of spider mites. When controlling other pests, ecologically selective pesticide application methods should be used as much as possible to carry out spot treatment or localized pesticide application. If conditions permit, natural enemies such as predatory mites and lacewings can be artificially raised and released.
