Diseases:

Botrytis: It mainly affects the base of seedling stems as well as the adult plants of sweet potato.

The seedling stem base is watery rot, which can cause sudden collapse; adult plant damage occurs in the near-ground stem, petiole and leaf blade watery light brown spots, the edge is not obvious, often causing leaf or stem base rot.

Prevention methods: early onset of the disease with 30% of the gray nucleicidal star wettable powder 800-1000 times solution, 20% of the fungus - polymyxin suspension 1500-2000 times solution or 40% of the mycorrhizal fungus net wettable powder 1000 times solution for spraying and control.

Virus disease: mainly affects the leaves of sweet potato. Disease leaves turn yellow, when serious, the upper leaves of the plant turn yellow, forming the upper yellow and lower green, plant dwarfing, and accompanied by obvious defoliation.

Prevention methods: 20% Copper Moguanide Acetate Wettable Powder 800-1000 times liquid, 1.6% Amino Fresh Ester Aqueous 2,000 times liquid or 1.45% Virus Bic 500 times liquid spraying control.

Pests:

Ground pests (mainly oblique night moth, kale night moth, small cabbage moth, bean leaf borer): mainly damage the leaves of sweet potatoes.

Methods of control: can be sprayed with 20% chlorpyrifos suspension 3000-5000 times liquid and carbofuran 1500 times liquid at the low larval stage.

Underground pests (mainly grubs, tigers, mole crickets, earthworms, etc.): mainly harm the tuberous roots of sweet potatoes.

Methods of prevention and control: can be respectively in the main vine after centering and tuberous root expansion early with 50% phoxim emulsion 500 times or 40% chlorpyrifos emulsion 800-1000 times the root irrigation 2 times.
