- The black sooty mould can be sticky and is the result of a whitefly attack.
- Cabbage whitefly overwinters on brussel sprouts as adult insects.
- Adult whitefly and their nymphs suck sap from the sprout plant and excrete a sugary substance (honeydew) onto the leaves.
- Sooty moulds then grow on this sugary substance – and can make a real mess of the sprout buttons.
- The warmer the weather the worse the problem is.

This tip on how to prevent black mould came in from Darren:
I live in Manchester. Don’t have a greenhouse. It’s v damp here. I’ve been preventing the black mould on my plants using anti-bacterial washing up liquid in a mister. But you need to get in early.

Wet weather is causing strawberries to suffer from grey mould (Botrytis cinerea).
Grey mould, sometimes known as Botrytis blight, is caused by a fungus Botrytis cinerea which spreads in cool, rainy weather around 60 F. The disease is particularly damaging when rainy, drizzly weather continues over several days.
Symptoms of Grey Mould
The rot usually starts at a point of contact such as the soil or other fruits. The berry turns brown and remains firm. White mould is sometimes seen, and the whole berry can rot.

Control of Grey Mould -
* is by inspection and hygiene. Always take a paper bag when inspecting the strawberry plants & place infected fruit in the bag to avoid spreading the spores.
* Carry out inspections when the plants are dry & dew has dried, to avoid spreading the spores in ideal conditions.
* Avoid misting the plants, or overhead watering, if Botrytis is a problem.
* Give plants plenty of space, to allow air circulation and rapid drying of plants
* In autumn, cut stalks at or below ground level & remove all strawberry plant debris from the garden. This is to prevent overwintering of the fungus as tiny, black sclerotinia in dead
leaves and stalks.
* Fungicides are available to control Botrytis. Always follow the manufacturer’s instructions on the packet.

Many strawberries have just a patch of light brown rot. This can be cut off, and the remaining strawberry can be used to make a strawberry sponge!
