What specific miticide works well to control eriophyid mites

Eriophyid mites are a common pest that can be seen on crops grown in all regions of our country, so what specific miticide works against eriophyid mites?

I. Basic information about eriophyid mites

As a common pest, eriophyid mites are generally distributed in such provinces and regions as Guangdong, Guangxi, Fujian, Hainan, Sichuan and Yunnan.

Generally, in early March of the following year the overwintering mites begin to become active and migrate to spring shoots and flower clusters to cause damage, with the most severe damage from March to May.

Once a crop is infested with eriophyid mites, yellowish-green patches first appear on the undersides of damaged young leaves, the damaged spots are sunken, and the affected parts become deformed and form galls; the host tissue inside the galls produces grayish-white fuzz due to irritation, and the fuzz gradually turns yellowish-brown, reddish-brown and finally dark brown, resembling felt. The surface becomes uneven and loses its luster, and may even swell and twist; the damaged parts of the leaves show hyperplasia and thickening.

II. What specific miticides work against eriophyid mites?

Nissol, trichlorfon, isocarbophos emulsifiable concentrate and omethoate emulsifiable concentrate, etc., used according to the product instructions.

General usage:

After pruning diseased and insect-infested branches and leaves in winter, spray lime sulfur mixture at 1000 times dilution once; in mid-to-late April spray Nissol + trichlorfon once; in mid-to-late July spray Nissol + 40% isocarbophos emulsifiable concentrate at 1000 times dilution, or Nissol + 40% omethoate emulsifiable concentrate at 1000 times dilution or 20% dicofol at 800 times dilution, etc.

III. Other control methods for eriophyid mites

1. Biological control

Protecting and making use of natural enemies such as predatory mites plays a positive role in controlling the population of eriophyid mites.

2. Agricultural control

Prune off damaged branches and leaves, weak branches, overly dense branches, shaded branches and dead branches, and burn them in a centralized manner to improve ventilation and light penetration and reduce the source of the pests.

Carry out routine management well, fertilize reasonably, strengthen the tree vigor and improve the stress resistance of the plants. Control the sprouting of winter shoots, worsen and cut off the food source, reduce the overwintering pest source, fundamentally improve the ability to resist them and control the damage.
