1. Leaf blight

Generally at the beginning of June, irregular brown disease spots appear at night or at the leaf edge, gradually extending inward, until spreading into blocks, causing the leaves to gradually dry up to death, and in serious cases, it will lead to leaf shedding and plant death. The disease is more serious in high temperature and heavy rain. If it is not prevented in time, the pathogen will spread to the whole field in a short time, causing great harm.

Control technology: select the land with high terrain and good drainage to plant, plough the soil before planting, reduce the source of overwintering disease, pull out the diseased plant and burn it in the field in time, and spray Bordeaux solution or carbendazim solution to prevent and cure it.

The main pests of Scutellaria baicalensis Georgi are ground tigers and moths, which can harm the root system and young parts of the plant, and seriously affect the normal growth and development of the plant.

Prevention and control methods: physical control and chemical control can be used comprehensively, artificial capture can be used to eliminate ground tigers, and black light can be used to trap and kill moths. You can also spray dimethoate, dichlorvos and other pesticides for control, but you need to pay attention to the concentration of the agents, so as not to cause drug residues.
