The diamondback moth (*Plutella xylostella*) is a common pest on cruciferous vegetables, primarily active on the undersides of leaves and tender shoots. When populations are high, leaves are chewed and plant vigor is reduced. For effective control of diamondback moth on cruciferous vegetables, early intervention and precise targeting of the affected plant parts are critical—abamectin·acetamiprid 1.5% ME (microemulsion) is registered for use against diamondback moth on cruciferous vegetables.
*Plutella xylostella* is most susceptible and easiest to control during the early instar larval stages. Once the population surges and the larvae begin rolling the leaves, insecticide application becomes both costly and difficult to manage. Before spraying, carefully determine whether the larvae are located on the upper or lower leaf surface, and whether they are in the heart leaves or the ear/head region, and ensure thorough coverage of the target sites.
Abamectin·Acetamiprid 1.5% Abamectin·Acetamiprid Microemulsion, Registration No. PD20083635 (subject to the actual label). Used for controlling diamondback moth (Plutella xylostella) on cruciferous vegetables, at a rate of 60–80 mL per mu (667 m²) diluted with water for foliar spray. Apply during the early larval stage, and reapply at intervals of 7–10 days depending on pest pressure. Observe the pre-harvest safety interval.
Ensure thorough spray coverage of all primary infestation sites, including the undersides of leaves and tender shoots. For abamectin–acetamiprid microemulsion, rotate with products of different modes of action to delay resistance development. Adhere to the pre-harvest interval and avoid application during bee foraging periods. Always follow the label instructions for specific details.
