Medicinal Herb Cultivation 0 views
The main pests and diseases of honeysuckle are honeysuckle brown spot disease, which harms the leaves and occurs from July to August. After the disease develops, the spots on the leaves are round or polygonal due to the restriction of leaf veins, yellow-brown, and in humid conditions there is a gray mold-like substance on the underside of the leaves. Effective control methods are to promptly remove diseased branches and leaves, strengthen cultivation management, and increase the application of organic fertilizer to enhance disease resistance. In addition, spraying Bordeaux mixture at a ratio of 1:1.5:200 in the early stage of the disease can effectively control brown spot disease. The main insect pests of honeysuckle are aphids and coffee tiger longhorn beetles. To control aphids, 40% dimethoate emulsifiable concentrate 10

In addition, spraying Bordeaux mixture at a ratio of 1:1.5:200 in the early stage of the disease can effectively control brown spot disease.

The main insect pests of honeysuckle are aphids and coffee tiger longhorn beetles. To control aphids, a 1000-1500 times dilution of 40% dimethoate emulsifiable concentrate can be used for prevention and spraying to kill them. To control coffee tiger longhorn beetles, dead branches and fallen leaves can be burned to destroy the environment for the growth of their eggs; or in July to August, natural enemies can be artificially released. The natural enemies of coffee tiger longhorn beetles include red-bellied ichneumon wasps and swollen-legged wasps, and the suitable release density is 1500 insects/hm2, with obvious control effects; in addition, a sweet and sour toxic liquid (1 sugar:5 vinegar:4 water:0.01 trichlorfon) can also be used for trapping and killing.
