Spider mites are the most common insect pests in the process of citrus planting, this insect occurs in many generations, refractory to medication, citrus plants are damaged and cause litter, and young fruits fall off in serious cases, which directly affects citrus yield. In order to effectively control citrus red spider mite, we need to understand this insect first.
First, the life Xi of citrus red spiders.
Citrus spider mites mainly live on the leaves, fruits, and branches of citrus plants. It usually starts in the spring, peaks in the summer, and gradually decreases in the fall. Citrus red spider spider mainly affects the growth of citrus by sucking the sap of citrus plants.

Secondly, strengthening fertilizer and water management, pruning diseased branches, and removing fallen leaves can all reduce the number of spider mites. In addition, pay attention to pruning in spring and summer to increase ventilation and light transmission and reduce the occurrence of spider mites. The use of fruit arhat and sodium nitrate naphthalene acetic acid during the citrus growing period can make the citrus tree lush and enhance its resistance and prevent problems before they occur.
