Caterpillars (Cabbage whites)


Major plant pest causing considerable plant damage to a wide variety of plants.  Cabbage white caterpillars are a major pest of all brassicas but can also be seen on swede, turnip and parsnip.   Large, irregular holes can be seen on leaves often with feeding damage occuring on the leaf edges.  Black frass (droppings) usually visible over the leaves. The caterpillars are usually visible on the plant and feed during the day. These caterpillars are the grubs of the cabbage white butterflies the females can lay several eggs on brassicas during the summer.

Product Solution: Spray with Sprayday Greenfly Killer or Provado Ultimate Fruit and Vegetable Bug Killer - ready to use / concentrate. 

Cultural measures: Remove and destroy clusters of eggs when seen. Pick off caterpillars by hand where ever possible (particular problem on all brassica species). Grow brassicas under fleece to try to prevent the female butterflies from laying eggs on the plants.
