Metasequoia red blight: immediately after the end of the plum rain season, 1% Bordeaux liquid is sprayed on the crown for 5 times, once every 10 colors for 15 days, the disease can be controlled. Color roll moth: the best control period is the early stage of larval sting (early and middle April). 50% fenitrothion, 40% dimethoate, 80% dichlorvos and pyrethroids can be used in dry season (July and August).

Metasequoia red blight: immediately after the end of the plum rain season, 1% Bordeaux liquid is sprayed on the crown for 5 times, once every 10 colors for 15 days, the disease can be controlled.

Color roll moth: the best control period is the early stage of larval sting (early and middle April). 50% fenitrothion, 40% dimethoate, 80% dichlorvos and pyrethroids can be used in the dry season (July and August). The larvae can be removed manually (even bags), collected and burned, or the larvae can be sprayed with 1000 times solution of fenitrothion.

Black-winged termites: the most effective way to control termites is to spray mirex from May to June. 3% carbofuran (USA) can also be used. L0~l5g is applied to each plant to prevent Rain Water from scouring and sun exposure, so as to maintain its efficacy for a long time.
