Methods and Technical Key Points for Preventing and Controlling Pests and Diseases of Gastrodia elata
I. Diseases are mainly infections by miscellaneous fungi such as green mold, blue mold, and Mucor. When they occur severely, they can inhibit the growth of Armillaria mellea and can also infect Gastrodia elata tubers, causing rot. Prevention and control methods: (1) Choose well-drained plots for planting; (2) Select high-quality fungal wood; (3) Control temperature and maintain moisture during cultivation; (4) Fill the gaps between fungal wood with humus soil or rice grains. II. Pests mainly include white grubs, mole crickets, golden leaf beetles, termites, rats, and damage by livestock and poultry. Prevention and control methods: (1) Light trapping to kill; (2) Use 90% trichlorfon at 1000 times or 50% phoxim at 1000 times

What are the methods for controlling diseases and pests of Gastrodia elata?
I. Diseases and their control 1. Causes of the disease. The primary pathogens of Gastrodia elata diseases are mainly other basidiomycetes among the fungi besides Armillaria mellea, which infect the fresh wood and fungal wood symbiotic with Gastrodia elata's Armillaria mellea, competing with Armillaria mellea for nutrients. In severe cases, they not only inhibit the growth of Armillaria mellea and reduce the yield of Gastrodia elata, but also directly infect the tubers of Gastrodia elata, causing soft rot of Gastrodia elata (called tuber soft rot) or rotting death (called tuber rot). This disease mostly attacks and causes damage when the environment is poor, such as high temperature and high humidity, poor aeration and other conditions unfavorable to the growth of Gastrodia elata, causing the skin of the Gastrodia elata tuber to turn yellow and wither,

What are the methods for controlling pests and diseases of honeysuckle?
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

How to effectively control the Schisandra leaf-rolling worm
It occurs from July to August. The larvae are initially white, later turning green. Young larvae bite and feed on the leaf mesophyll; after the 3rd instar they roll leaves and feed, affecting fruit development. Control methods: (1) Before the larvae roll the leaves, spray with 80% trichlorfon at 1000-1500 times dilution. (2) After the leaves are rolled, spray with 40% dimethoate emulsifiable concentrate at 1000-1500 times dilution. (3) Spray with 50% phoxim at 1500 times dilution. (4) Spray with 50% phosphamidon emulsifiable concentrate at 2000 times dilution. (5) Before and after the larvae roll the leaves, they can also be caught by hand.

Methods for Controlling Underground Pests of Codonopsis pilosula and Key Technical Points
The main underground pests harming Codonopsis pilosula are white grubs, cutworms and mole crickets; the above-ground pest is spider mites. Control methods for underground pests: use poisoned soil and poisoned bait to lure and kill them. Poisoned soil preparation: use 0.5-1.5 kg of 35% endosulfan per mu, 15 kg of soil, mix and scatter among the seedling roots; poisoned bait preparation: use 1 kg of roasted cake meal per mu, add 35 g of trichlorfon, mix well with water, scatter on the bed surface and beside the beds, in the furrows or on the ridges. Control methods for above-ground pests: the above-ground pest of Codonopsis pilosula is spider mites, generally
