What kind of medicine should be given to the jujube tree during the medication time?

Spraying strychnine or methyl topiramate in mid-late June can prevent rust, spraying mancozeb and verapamil every half a month in early July can prevent fruit shrinkage, and spraying Bordeaux liquid in late July can prevent anthracnose. After germination in spring, dichlorvos and dimethoate were used to control jujube gall midge before rolling leaves, omethoate was used to control shell insects before and after wheat harvest, and dichlorvos emulsion or pyrethroid pesticides were injected into the wormhole from July to October to kill longicorn beetles.

Control methods of diseases and insect pests in jujube trees:

The main results are as follows: 1. After cleaning the fallen leaves of deciduous winter jujube trees, the withered branches and leaves, diseased fruits and weeds in the garden should be buried or burned in time, so as to reduce the number of pathogens and pests overwintering.

2. Deep ploughing jujube orchard, especially the jujube orchard with barren land and high salt content, can loosen the soil and preserve soil moisture, accumulate rain and snow, promote root growth, and turn the overwintering pests to the ground, prey by natural enemies or freeze to death by natural enemies.

3. Scraping the old bark in early winter or early spring scraping off, burning or burying the old warped skin, diseased skin and worm-eaten skin at the branches of the trunk, big branches and branches in early winter or early spring can effectively eliminate the diseases and pests that survive the winter in the rough bark. The skin scraping thickness should be yellowish green with slight exposure to the cortex. after scraping, apply 40% Fumet arsine wettable powder 10-100 times or 5-10 Baomedo stone sulfur mixture to protect the wound.

4. after the trunk is coated with white jujube leaves, white agent is used to eliminate the overwintering diseases and insect pests in the trunk and the base of the big branch. The whitening agent can be prepared with 25 parts of water, 10 parts of quicklime, 1 part of stone-sulfur mixture, 1 part of salt and a small amount of animal oil, and an appropriate amount of fungicides and pesticides can be added to the whitening agent to increase the effect.

5. after the artificial insecticidal jujube tree has fallen leaves, combined with winter shearing, the branches of diseases and insect pests can be cut off, and the overwintering eggs and cocoons such as big bag moth, diamondback moth, cicada and so on can be removed.

6. spraying 5 Baume stone sulfur mixture and 200 times pentachlorophenol sodium after defoliation and before germination of jujube can eliminate overwintering pathogen and eggs.

7. After picking the winter jujube with a bunch of straw, the base of the trunk is tied up with rice straw for a week to lure pests into the grass to survive the winter and prevent frost injury. Before the jujube tree germinates, untie the straw and take it out of the garden to burn.

8. The binding film can effectively prevent the killing of tree pests by binding the plastic film around the width of 20cm at the base of the tree trunk in early spring, and binding the middle of the film with a poison rope to roll the film down into a trumpet shape.

9. Plastic film mulching on the tree disk in early spring can not only prevent the spread of ground germs and some insect pests to the trees, but also inhibit the growth of weeds, increase the ground temperature and reduce water evaporation.

The above is the jujube tree medication time what drugs related to the introduction, I hope it will be helpful to everyone.
