Fungal Disease on Vegetables
As you can see with this list there are a fair number of fungal diseases that can strike various vegetables in the garden. They will hit at different times in the season. Very often they are caused by weird weather; cold and wet or hot and wet, etc.
We say don’t worry about identifying each fungal disease. It’s not worth the effort and you really don’t need to. Usually once a fungal disease strikes there is nothing you can do to “cure” it.
The main job is to “prevent” all fungal diseases from attacking any of your vegetables. You can now do that with just one product and that is ACTINOVATE, a relatively new biological fungicide that is very effective in preventing most fungal diseases above and below the soil surface.
Here is the fungal disease prevention program for all your vegetables:
1. Every time you plant a vegetable seedling you include some Actinovate in the hole
2. Then when a vegetable seedling gets to be 5 or 6 inches tall you begin a monthly spray program with Actinovate right to first frost.
3. IMPORTANT – If any vegetable in your garden had any fungal disease problem last year, then for that vegetable this year you spray Actinovate every two weeks from planting to harvest.
If you follow this program your vegetables should seldom suffer from any of the following fungal diseases.
Pods are mottled with white, fuzzy fungus strands on them
Pale Areas on Upper Leaves
yellowing leaves with a greyish or white mold on their underside. Older leaves have tiny black fungi spots on their leaves, and slowly die in the autumn.
Leaves coated with white powder
Fruits develop small, round, water-soaked spots; later, fruits darken and rot
Water-soaked Spots On Pods, Stems
can occur on beans, as well as vegetables like brassicas, cucumbers, peppers, and tomatoes, creating sunken brownish spots. Remove and dispose of infected plants. Buy disease-resistant seed varieties.
Orange-tinged Spots Under Leaves
thrive in warm, wet weather and may affect vegetable crops such as potatoes and tomatoes
Botrytis (grey mold)
is a common vegetable disease that affects plants such as lettuces and tomatoes.
is a fungal disease that attacks brassicas such as broccoli, cauliflower, and cabbage.
is a fungal disease that can affect any type of vegetable plant,
Fusarium wilt and verticillium wilt
are fungal diseases that cause leaves to turn yellow and look wilted. The yellow leaves turn brown and the disease usually starts from the bottom of the plant and works its way up, eventually killing the plant.
