Posted by TopVeg - June 27th, 2008

Potato blight can devastate a crop in a short time. It is important to keep potatoes protected against attack from potato blight.

New potatoes are not a concern as they have produced the tubers and will be eaten shortly. But main-crop potatoes have not started to bulk up, and an attack of potato blight now may mean that there are no potatoes to harvest. Read More »

Slugs on Strawberries

Posted by TopVeg - June 19th, 2008

This is a bad year for slugs on strawberries.slug-damage-on-strawberry

The slug population has exploded in the ideal conditions provided by the wet conditions last summer & this spring.

To reduce slug attacks on strawberries:

  • surround the strawberry row with oyster grit, or a similar medium, which the slugs do not like to cross.
  • place ’slug pubs’ amongst the rows. These are small containers of beer which the slugs drop in to.
  • leave grapefruit or orange skins in the row, which will attract slugs, & pick the slugs out every day & destroy.
  • purchase a pyramid slug trap.
  • elevate the strawberry plants on poles which the slugs cannot climb - see table top strawberries.

Slugs can devastate the strawberry crop, so it is worth taking time to control the slugs, using a number of different methods.

Leather Jacket Control

Posted by TopVeg - June 6th, 2008

leatherjacketLeather jackets have been a great problem this spring. They have attacked young cabbage plants and young courgettes. They nip the stem at soil level - killing the plant.

There are few chemicals available for use on vegetables which kill leatherjackets. The active ingredient for the job is chlorpyrifos, & Dursban is about the only product on sale. It is water soluble and should be well watered in to make sure it reaches the leather jackets in the soil.
