How to prevent and cure bunchy top disease by planting banana? Please introduce control methods for planting bananas can refer to the following methods to control bunchy top disease: 1. Establish a disease-free nursery and cultivate disease-free seedlings. The nursery should be set in a place where there is no banana garden within a radius of 2000 to 3000 meters, in order to prevent aphids from spreading disease, and an anti-insect net can be added in the seedling shed. 2. Use herbicides to kill diseased plants and replant disease-free seedlings. The banana plant with virus can be killed by injection of 10-15 ml glyphosate. During the operation, the pseudostem of the plant 15 cm above the ground can be injected into the base with a long syringe to kill the growth point of the underground stem. After about 15 days, the whole plant withered and died. The dead and diseased plants should be dug up in time, and the soil around the diseased plants should be turned up, disinfected with lime, exposed to the planting pit, and the disease-free seedlings can be replanted 15 days later. 3. Control aphids. The tissue culture seedlings in the greenhouse were sprayed with 40% dimethoate EC 1000 × 1500 times or 5% fish rattan EC 1000 × 1500 times every 7-10 days. Aphid insecticides should be sprayed 2 times a month before 1.5 meters high in the field period during the peak period of aphids in March-May and August-October. 4. Renew the old banana garden regularly. In one step, the banana garden should be renewed after it has been put into production for 2 ~ 3 years, which has an obvious effect on reducing the incidence of disease.
