1. Anthrax: if the plants are too dense and poorly ventilated during planting, it is easy to cause anthrax. The damaged part is the stem. After the disease, there will be small spots like water stains on the stem nodes. The color will be light brown, and then expand into irregular spots. At the beginning of the disease, there will be brown spots on the leaves and gangrene in the center of the spots. After the disease, the plant will be burned, and then the drugs such as anthrax Fumei will be sprayed.
2. Rust: there are swollen spots on the stem epidermis at the beginning, which will make the tissue black in serious cases. Daily ventilation should be strengthened, and after the onset of the disease, it should be sprayed with diniconazole or ammonium Naipu.
3. Scab: this disease will lead to the appearance of reddish brown spots on tubers, which will rot and die in a few days. After the onset of the disease, it can be sprayed with topiramate.
1. Snails and slugs: they can chew on leaves and branches, so it is necessary to remove weeds nearby, and then spray special medicine to kill snails.
2. Red spider: the red spider is relatively small in size, and it will chew the stems and leaves, resulting in rough damage. It can be used as insecticides such as picoline, carbofuran, imidacloprid, etc.
3. Aphid: the aphid will reproduce in large quantities and absorb nutrients in the plant, resulting in curly young leaves, which can be sprayed by the God of flowers.
