Citrus aphids never seem to be fully controlled? Master the timing of acetamiprid application—targeting the early instar stages is the key to saving on pesticide use.

Aphids are common pests on citrus trees, primarily active on the undersides of leaves and tender shoots. When populations become large, they damage leaves by feeding and reduce overall plant vigor. Early intervention and precise targeting of the affected plant parts are key to controlling citrus aphids—acetamiprid 20% WP is registered for use against aphids on citrus trees.

Aphids exhibit the least resistance and are easiest to control during the early instar stages. Once populations surge and leaves begin to curl, subsequent spraying becomes both costly and difficult to manage. Before applying insecticides, determine whether the pests are located on the adaxial or abaxial leaf surface, and whether they are concentrated in the whorl or the ear, ensuring thorough coverage of the critical target sites.

Acetamiprid 20% Acetamiprid Wettable Powder, Registration No. PD20082178 (subject to the actual label). Used for controlling aphids on citrus trees, apply as a foliar spray at a dilution rate of 10,000–16,667 times with water. Apply during the early instar stage, and reapply at intervals of 7–10 days depending on pest pressure. Observe the pre-harvest interval.

Ensure thorough spray coverage of all primary infestation sites, including the undersides of leaves and tender shoots. For acetamiprid wettable powder, rotate with products of different modes of action to delay resistance development. Adhere to the pre-harvest interval and avoid application during bee activity periods. Always follow the label instructions.
