Prevention and control of fruit shrinkage disease of jujube

Published: 2024-11-22 Author: mysheen
Last Updated: 2024/11/22, The occurrence of jujube fruit shrinkage disease is positively correlated with the density of piercing sucking insects, and the disease is often prevalent due to high atmospheric humidity, especially in intermittent rainfall or continuous overcast days. Control methods: if the susceptibility index of ① is relatively high last year, we should first clean up the fallen leaves and fruits in the jujube orchard and concentrate on treatment so as to cut off the source of transmission. ② strengthens the fertilizer and water management of jujube orchard and improves the resistance of trees. For older trees, scrape and burn the old bark before sprouting, and spray stone-sulfur mixture on the whole tree. Chemical control of ③: using fungus No. 1

The occurrence of jujube fruit shrinkage disease is positively correlated with the density of piercing sucking insects, and the disease is often prevalent due to high atmospheric humidity, especially in intermittent rainfall or continuous overcast days.

Prevention and control methods:

If the susceptibility index of ① is relatively high last year, we should first clean up the fallen leaves and fruits in the jujube orchard and concentrate on treatment so as to cut off the source of transmission.

② strengthens the fertilizer and water management of jujube orchard and improves the resistance of trees. For older trees, scrape and burn the old bark before sprouting, and spray stone-sulfur mixture on the whole tree.

Chemical control of ③: fungus No. 1 was sprayed with 800x solution or streptomycin sulfate solution 6500 times to kill pathogens for the first time at the end of June and every 10 days from the end of July to early August.
