Pest killing management method in citrus fruiting period

Abstract

The present invention relates to the field of insecticides, in particular to a management method for insecticide during the fruit-setting period of citrus, spraying insecticidal water on the whole leaves of citrus 10 days after flowering, and then spraying insecticidal water every other month until the citrus fruit is harvested In the previous month, the insecticidal water was 3000-5000 times the aqueous solution of the insecticide, and the raw materials of the insecticide were 10-20 parts by weight of copper sulfate, 10-15 parts of thiamethoxam, bromine 5-10 parts of cyprothrin, 10-15 parts of flubendiamide, 15-25 parts of calcium oxide, and 20-35 parts of calcium chloride. It can effectively target pests on leaves and fruits, especially against pests of Lepidoptera and Orthoptera. It can also effectively supplement calcium to ensure the normal growth of citrus and reduce the occurrence of cracked fruit and puffy fruit.

[0003] Calcium is an essential element for the growth of citrus. Calcium deficiency will lead to fruit cracking, soft fruit, floating fruit, frost fruit, sun fruit, etc. The demand for calcium in citrus is more than twice that of phosphorus, so calcium supplementation is very important! However, the existing insecticides often only have insecticidal effect and have no calcium supplement effect
