How to treat jujube leaflet disease? What kind of medicine do you use? What caused it?

Dichlorvos, thiazide and thiazide can be sprayed on the plant every 7 days for one month, and the diseased branches of jujube can be cut off in time, which can not only effectively reduce the consumption of soil nutrients, but also prevent bacteria from infecting other branches and leaves. Jujube trees suffer from lobular disease, which is generally caused by diseases and insects such as planthopper, thrips, jujube gall midge, and may also be lack of nutrients.

I. treatment of jujube lobular disease

1. Spraying chemicals

Jujube lobular disease, also known as jujube mad disease, mainly resists jujube tree absorbing nutrients in the soil, generally caused by planthopper, thrips, jujube gall midge and other diseases. Dichlorvos, thiazide, thiamethamide and other agents should be sprayed every 7 days for a continuous month.

2. Pruning branches

It is also necessary to cut off the diseased branches of jujube in time, which can not only effectively reduce the consumption of soil nutrients, but also prevent bacteria from infecting other branches and leaves, which can make the situation more serious and promote jujube to recover its vitality gradually. it can also increase the fruit yield of jujube, which is beneficial to the healthy growth of jujube.

3. Give enough light

The jujube tree is a kind of fruit tree that loves the sun. generally, after spraying the jujube tree, the jujube tree should be cultured in a sunny and ventilated environment, which can promote the jujube tree to recover more quickly and make the jujube tree branches and leaves grow more luxuriantly.

4. Topdressing fertilizer

If the jujube tree suffers from lobular disease, it can also be applied nitrogen, phosphorus and potassium compound fertilizer in time, generally mainly applying potassium compound fertilizer, or using rotten organic fertilizer instead of compound fertilizer, which is helpful to increase the disease resistance of jujube trees and promote jujube trees to grow well in the soil to avoid the phenomenon of overgrowth.

Second, how is the jujube leaflet disease caused?

1. Jujube suffers from lobular disease, which is generally caused by diseases and insects such as planthopper, thrips and jujube gall midge, and may also be caused by lack of nutrients. Lobular disease is one of the serious diseases of jujube trees in China, and there is little fruit in the second year. The diseased tree is also called "male jujube tree". The whole tree will die 3-4 years after the disease, which is a great threat to production.

2. Among them, the disease is more serious in Guangxi, Yunnan, Sichuan, Chongqing and other cities. In recent years, lobular disease broke out one after another in Meishan, Sichuan and Guanyang jujube area in Guangxi, and became more and more serious, which can be spread by grafting and root splitting. The incubation period of the disease is more than 25 days to 1 year.

3. In general, Jinsi jujube is more susceptible to disease, and the disease is more serious in jujube orchards with dry and barren soil and extensive management. if diseased trees, diseased branches and diseased tillers are found in time to avoid the spread of germs, and the disease can be strictly dug up in the seriously diseased areas for years, the occurrence of the disease can be controlled.
