Detailed Explanation of Pest and Disease Control Techniques for Gastrodia elata Cultivation
Pest control: The main pests and diseases of Gastrodia elata include root rot, white grubs, and mole crickets. There are two causes of root rot: first, infection by miscellaneous fungi causes root rot in Gastrodia elata; second, excessive rain during the growing period causes root rot in Gastrodia elata.
Control methods: Choose well-drained land for planting Gastrodia elata. The fungal wood should be free of miscellaneous fungal infection, and the gaps between fungal wood should be filled properly. Pay constant attention to drainage. Adult and nymph pests damage the stems of Gastrodia elata and tunnel underground, and the cut surface of the damaged Gastrodia elata appears fibrous. Control methods: For the above two diseases and pests, use light traps to kill the adults.
