Small holes are eaten in newly-emerged spring foliage. These holes increase in size as the leaves expand. The pale green caterpillars loosely bind young leaves together with silken threads, walk in a 'looping' action. The caterpillars also eat fruit blossom and make holes in apple fruitlets.
Product solution: Tie Boltac Greasebands to the trunks of fruit trees from October to stop the flightless moths reaching up into the tree canopy and laying eggs . Regularly inspect the tree and control newly hatched caterpillars in the spring with Sprayday Greenfly Killer, or Provado Ultimate Fruit and Vegetable Bug Killer Ready to Use/Concentrate.
