At the edge of the infected leaf, the tip of the leaf begins to turn yellow and eventually falls off. Brown spots appear on the infected pepper branches, and in severe cases, cork flowers appear and crack longitudinally. Dark brown pimples will appear in the early stage of fruit infection with acne. If not stopped in time, small spots will appear one after another, tree embolism will begin, the air will be humid, and bacterial liquid will flow out from the middle of the lump.

Pepper seeds should be soaked in warm water of about 55 degrees for 20-30 minutes to remove the germs on the pepper seeds. Do a good job in water and fertilizer management during pepper growth, drain water in time after rain, improve the growth momentum of plants and prevent acne.
