Cruciferous vegetable aphids are common pests on cruciferous vegetables, primarily active on the undersides of leaves and tender shoots. When populations are high, leaves are damaged and plant vigor is reduced. For effective control of cruciferous vegetable aphids, early intervention and precise targeting of the affected plant parts are key—Yipianqing 10% Imidacloprid Wettable Powder is registered for use against aphids on cruciferous vegetables.
Aphids exhibit the least resistance and are easiest to control during the early instar larval stages. Once populations surge and leaves begin to curl, subsequent insecticide applications become both costly and difficult to manage. Before spraying, 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 target sites.
A piece of Qing 10% Imidacloprid Wettable Powder, registration certificate No. PD20040117 (subject to the actual label). Used for aphids on cruciferous vegetables, also covering wheat aphids and rice planthoppers, at a rate of 10–20 g per mu diluted with water for foliar spray. Apply during the early instar stage, and re-apply at intervals of 7–10 days depending on pest pressure, while observing the pre-harvest interval.
Ensure thorough spray coverage of all primary infestation sites, including the undersides of leaves and tender shoots. For imidacloprid 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 foraging periods. Always follow the label instructions.
