What's eating my crabapple 'evereste'?

Crabapple 'Evereste' is targeted by aphids, woolly aphids, codling moth caterpillars, apple sawfly, and winter moth caterpillars. Deer and birds browse the fruit in autumn. Aphids are by far the most frequent problem, clustering on new shoots and causing leaf curl. Sticky barriers, winter washing oil, and natural predators keep most threats manageable.

Tightly curled, distorted young leaves and shoot tips; sticky honeydew and sooty mould; fruit may be misshapen Encourage ladybirds and lacewings; blast off colonies with a strong jet of water; use insecticidal soap or neem oil spray on heavy infestations; apply winter tar-oil wash to kill overwintering eggs

White, cotton-wool-like tufts on bark and stems; underlying galls and bark cracking weaken branches Scrub tufts off with a stiff brush and methylated spirits; paint pruning cuts; spray with thiacloprid-based product in spring (UK check approval); remove badly galled shoots

Early fruit drop in June; ribbon-like scarring on fruitlet surface; a tunnel with frass inside the fallen fruitlet Collect and destroy fruitlets that drop in June; apply a pheromone trap in blossom time to monitor adults; use kaolin clay or approved insecticide at petal fall

Holes and ragged edges in emerging leaves and open blossom; silk threads webbing young foliage together Apply sticky grease bands around trunk from October to April to trap wingless females; spray Bacillus thuringiensis (Bt) at bud burst on newly hatched caterpillars
