This is a viral disease. Viral diseases are mainly prevention and a small amount of elimination. First of all, we should pay attention to the use of aphid ketone or thiamethoxam to treat vector pests such as whitefly and aphid. Strengthening fertilizer management is conducive to resisting viruses. If a small number of infected strains are found, they should be removed in time to avoid infection. It is suggested to spray oligosaccharide, chain protein, moroxydine hydrochloride, dinotefuran and foliar fertilizer. Or alternatively spray 1200 times of ammonium phosphate +600 times of 5% aminooligosaccharide +65438 times of 3% acetamiprid +0200 times of foliar fertilizer or 800 times of 5% acetaminophen +600 times of 5% aminooligosaccharide +3000 times of imidacloprid+foliar fertilizer, and spray once every 7 days.
