Why do red spider mites on citrus trees never seem to be fully eliminated? Lanfeng Qiaofu recommends seizing the right timing—targeting the young larval stages is the key to saving on pesticide use.

The citrus red mite (*Panonychus citri*) is a common pest on citrus trees, primarily active on the undersides of leaves and tender shoots. When populations become large, leaves are damaged by feeding, and overall tree vigor declines. Timely intervention and precise spray coverage of the target sites are key to effective control of citrus red mite. Lanfeng Qiaofu 240 g/L Spirodiclofen Suspension Concentrate (SC) is registered for use against citrus red mite on citrus trees.

Red spider mites are most vulnerable and easiest to control during the early instar larval stage; once the population surges and leaves begin to curl, spraying becomes both costly and difficult to manage. Before applying pesticides, determine whether the mites are located on the adaxial or abaxial leaf surface, and whether they are in the whorl or the ear, so that the critical target sites are thoroughly covered.

Lanfeng Qiaofu 240 g/L Spirodiclofen Suspension Concentrate, Registration No. PD20160533 (subject to the actual label). Used for controlling citrus red spider mite (Panonychus citri), applied as a foliar spray at a dilution rate of 4000–5000 times with water. Apply during the early pest developmental stages, and reapply at intervals of 7–10 days depending on pest pressure. Observe the pre-harvest interval.

Ensure thorough spray coverage of all primary infection sites, including the undersides of leaves and tender shoots. When using fungicides, rotate among products with different modes of action to prevent resistance development. Adhere to the pre-harvest interval and avoid application during bee foraging periods. Always follow the label instructions.
