Q

Please help. I have had my ap­ple tree about 30 years and al­ways had a good yield, but this year although the ap­ples were a bet­ter crop, nearly every one had some­thing eat­ing into the mid­dle.

Is there any­thing I can do? I’ve al­ready tied a band around the tree and sprayed. Thank you.

Grease bands around ap­ple trees are a method of stop­ping win­ter moth dam­age – these cater­pil­lars eat the leaves and fruitlets.

How­ever, your tree may be un­der at­tack from the codling moth whose cater­pil­lars bur­row into the cen­tre of the ap­ple and de­stroy the fruit.

In spring you can treat the trunk with plant-based hor­ti­cul­tural oil which will help re­move lar­vae and eggs.

In May, hang pheromone traps on the tree which will cap­ture the male moths, thereby re­duc­ing the amount of eggs hatched.

There are also bi­o­log­i­cal con­trols avail­able to ap­ply to the trunk in Septem­ber. These are worms which de­stroy the cater­pil­lars.

If you want to spray, do so in late June and not when the tree is in flower so as to pro­tect ben­e­fi­cial pol­li­nat­ing in­sects.

Bet­ter still, choose an or­ganic plant-based in­sec­ti­cide which will be less harm­ful to the en­vi­ron­ment.
