French Beans Pest & Disease
 

French Beans Pest & Disease - Halo Blight

Symptoms Brownish spots on the leaves are surrounded by a light coloured 'halo'. This disease comes from the seeds themselves. Cause and Cure Possible causes are home-saved seed from the previous year not stored correctly; soaking French bean seeds before planting; seeds bought from a bad source. It's a good idea to examine the seeds at planting time and reject any which are marked, wrinkled or unusually shaped. There is no cure for Halo Blight, dig up and destroy the plants.

French Beans Pest & Disease - Slugs

Slugs find all parts of French Beans delicious - the roots, stems, leaves and of course the pods. Dwarf varieties are the most affected because their foliage and crops are nearer the ground. Climbing French beans are less affected with only the lower leaves being eaten. Click here for an in depth look at how to deal with slugs.
