Anonymous users2024-02-13Citrus is still very sensitive to drugs when flowering, and improper or excessive use of drugs at this time is easy to cause drug damage, resulting in a large number of flowers and fruits, or causing fruit deformity and stunted development. The insect pests and diseases that appear in the flowering period are just thrips, gray mold, and scabs, and most of the pests and diseases can be controlled before flowering and early flowering.
When the adult insects are unearthed, the ground is sprayed for control, and 200 grams of phosphine emulsifiable concentrate and 15 kg of fine soil can be mixed and sprinkled on the ground per mu, and it can be applied once every other week, and it can be applied twice in a row, which can effectively prevent flower buds and maggots from going to the tree. In the flowering period, organophosphorus pesticides can not be used, and emulsifiable concentrate-type agents can not be used. It is recommended that the suspension form is safer.
In addition to paying attention to the damage to flowers and leaves of some pesticides during use, we should also pay attention to the temperature characteristics of the pesticides used, so as to achieve drug safety and good control effect. The temperature warms up in spring, citrus pests and diseases are coming, the prevention and control of pests and diseases during the flowering period is a headache, the novice planting does not know how to prevent and control, even the master is helpless, often it rains and has no chance to spray, if the pests and diseases in the flowering period are not well controlled, it will affect the quality of the flowers.
In addition to pest control, we also need to control sunburn fruit, the most effective way to burn fruit is whitening, for the choice of whitening agent, you can choose a whitening agent suitable for local climatic conditions and varieties, which will not be explained here. Many pests and diseases of orange have a mutually reinforcing effect, so when spraying and controlling many pests and diseases, it is advocated that bacteria, pests, and mites are controlled together. Some drugs also have a promoting effect and can improve the prevention and treatment effect.
If there is an orchard with extensive management or abandoned nearby, persuade the other party to strengthen pest control, or the abandoned orchard is recommended to be cut down and burned. Citrus pest control is not just a one-person business, such as psyllid control, it is best to spray pesticides in nearby orchards at the same time.
