Weekend work: Cuttings: Weevil's enemy

THE MOST effective treatment for vine weevils, Aldrin, was withdrawn from the market a little while ago, much to the anguish of nurserymen and auricula growers. Vine weevils - fat underground grubs that feast on the roots of potted plants - have increased dramatically with the growth in use of peat- based composts.

One answer is nematodes - parasites that prey on underground insect larvae. They remain active only at temperatures above 14C, but you can arm yourself with supplies for next season from Defenders Ltd, PO Box 131, Ashford, Kent TN25 5TQ.
