Tomato stem base rot mainly harms the stem base, and the course of the disease develops to the later stage when the stem base cortex rots, and the upper leaves turn yellow, wither and even die. Chemical control can be carried out by spraying the stem base or irrigating the roots with Bacillus subtilis, metalaxyl, copper complex and fludioxonil at the early stage of the disease. Spray every 5-7 days.
