How to prevent and control cabbage caterpillars on vegetables? Suhua Lübao (Suhua Green Treasure) is the right pesticide for this target pest.

The cabbage caterpillar (Pieris rapae) is a common pest on vegetables, primarily active on the undersides of leaves and tender shoots. When population densities are high, leaves are chewed and plant vigor is reduced. Timely intervention and accurate targeting of the affected plant parts are key to controlling this pest—Suhua Lübao 10% Cypermethrin Emulsifiable Concentrate is registered for use against cabbage caterpillar on vegetables.

The resistance of Pieris rapae (imported cabbageworm) is low and it is easier to control during the early instar larval stages. Once the population surges and the larvae begin leaf-rolling, insecticide application becomes both costly and difficult to manage. Before spraying, determine whether the larvae are located on the adaxial or abaxial leaf surface, and whether they are in the heart leaves or the ear/head region, and ensure thorough coverage of the target sites.

Suhua Lübao 10% Cypermethrin Emulsifiable Concentrate, Registration No. PD20040189 (subject to the actual label). Used for controlling imported cabbageworm (Pieris rapae) on vegetables, at a dosage of 20–30 mL per mu, diluted with water and applied as a foliar spray. Apply during the early larval stages; 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 cypermethrin EC, rotate with insecticides 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.
