What's eating my apple 'honeycrisp'?
Codling moth
Signs: Frass-filled tunnels through the core and flesh; premature fruit drop with an entry hole visible at the eye or side
Control: Hang pheromone traps from pink-bud stage to monitor; apply Codacide oil or a pyrethrin-based spray at egg-hatch; consider kaolin clay barriers
Apple sawfly
Signs: Ribbon-like scarring on fruitlet skin followed by early June drop; internal ribbon tunnel if fruit is cut open
Control: Apply a pyrethrin spray within 7 days of petal fall; collect and destroy dropped fruitlets; sticky yellow traps catch adults
Rosy apple aphid
Signs: Tightly curled, distorted leaves in spring; stunted fruitlets that remain small and deformed at harvest
Control: Squash colonies by hand early; spray with insecticidal soap or a neem-oil drench; encourage ladybirds and lacewings
Deer and rabbits
Signs: Bark stripped from the trunk base (rabbits) or shoots browsed off entirely (deer), especially autumn through early spring
Control: Fit spiral rabbit guards on young trunks; erect a wire fence or tree shelter; apply deer repellent spray on branches in late autumn
