What are the control methods for the wolfberry rust mite?

Medicinal Herb Cultivation 0 views
The wolfberry rust mite belongs to the family Eriophyidae. Swarms of mites densely cover the leaves and suck the sap, causing the leaves to turn rust-colored and drop early. Adult mites overwinter in bark crevices, bud axils and other places. The following year, after the wolfberry leaves unfurl in mid-April, they begin their damaging activity, and they begin laying eggs in late April. Late May to late June is the peak period of reproduction. After that, because the leaves turn rust-colored and the nutritional conditions deteriorate, the number of mites drops greatly. From late July to early August, new leaves emerge and a second reproduction peak appears. In mid-September reproduction slows, and after leaf fall in October the adult mites move to

Late May to late June is the peak period of reproduction. After that, because the leaves turn rust-colored and the nutritional conditions deteriorate, the number of mites drops greatly. From late July to early August, new leaves emerge and a second reproduction peak appears. In mid-September reproduction slows, and after leaf fall in October the adult mites move into branch crevices to overwinter.

Spray the tree canopy with 50% sulfur suspension concentrate at 300 times dilution in early May; if controlled in time, the outbreak can be kept in check. Spraying with 40% omethoate at 1000 times dilution can also achieve control.
