Occurrence and Control of Copper deficiency in Waxberry

Published: 2024-11-05 Author: mysheen
Last Updated: 2024/11/05, Bayberry shoot blight is caused by boron deficiency, so planned boron supplementation can eliminate the harm of the disease. Spray 0.1 to 0 during the growth of bayberry. 2 Borax solution for 2 to 3 times can effectively prevent and cure the disease. Root application can also be used, with 0.3 to 0.6 kg of borax per mu for mild boron deficiency and 1.3 per mu for severe boron deficiency.

Symptom trees are short, green-deficient and morbid, susceptible to diseases; upper leaves are deformed and discolored, new shoots are atrophied; roots and branches grow poorly, and there is often gum on branches; there are few fruits and seeds. The fundamental measures for the prevention and control of copper deficiency are to increase the application of organic fertilizer and copper-containing fertilizer. Power plant coal ash contains a small amount of ketones, which can be applied in acidic soil as appropriate. In the application of copper-containing pesticides, the effect of its residues should be considered to prevent the accumulation of copper in the soil and cause toxicity to red bayberry.
