Methods and Technical Key Points for Controlling Pests and Diseases of Gastrodia elata

There are two common diseases in Gastrodia elata cultivation: one is mold damage, and the other is rot disease.

Rot disease and its control

Gastrodia elata rot disease is caused by multiple factors. When seed tubers are damaged by pests, mechanical injury, or exposed to adverse high-temperature and high-humidity conditions, they are susceptible to infection by miscellaneous fungi, causing rot. Spray the plant surface with Hushu Jiangjun to disinfect and sterilize, prevent pest and disease infection, and improve the plant's disease resistance. When strengthening field water management, add Xin Gao Zhi Mo to prevent drought, prevent waterlogging, and preserve soil moisture.

In the middle and late stages of Gastrodia elata growth, spray the plant surface with the medicinal material Gen Da Ling to promote the transport of leaf photosynthetic products to the root system, improve the nutrient conversion rate and soil loosening capacity, cause the rhizome to expand rapidly, greatly increase the content of active substances, and improve quality.

Control measures

①Pay attention to regulating temperature and humidity, and provide the optimal conditions for Armillaria mellea growth to inhibit the growth of miscellaneous fungi;

②Select complete, unbroken, brightly colored white-headed seed tubers or water tubers as seed sources, and do not bruise or expose them to the sun during digging and transport;

③The culture material for planting Gastrodia elata is best piled up, disinfected, and dried in the sun to kill internal insects, pupae, and fungi, reducing damage.
