Garden diseases can vary depending on the type of plants and environmental conditions, such as humidity, soil moisture, exposure to pests (such as fungus gnats), as well as general soil health. Here are 10 common plant diseases that outdoor gardeners often encounter:
1. Powdery Mildew
Powdery mildew is a fungal disease that appears as a white powdery coating on the top side of leaves, stems, and flowers of plants. It affects a wide range of plants, including roses, cucumbers, and zucchini.
2. Tomato Blight
Tomato blight is caused by the fungus-like organisms Phytophthora infestans or Alternaria solani, which affects tomato plants, causing brown leaf spots, lesions on stems, and fruit rot. It can quickly spread and destroy an entire tomato crop, so if you see brown spots on tomato leaves, then it's important do your Arber Organic Immunity Boost & Defense routine.
3. Black Spot
Black spot is a fungal disease that affects roses and other ornamental plants. It causes black spots with feathered or fringed edges on the leaves, leading to defoliation if left untreated.
4. Rust
Rust is a fungal disease that manifests as orange, reddish, or brown spots that grow into pustules on the leaves, stems, and fruits of plants. It commonly affects roses, hollyhocks, and snapdragons.
5. Downy Mildew
Downy mildew is a fungal disease that affects a variety of plants, including cucumbers, lettuce, and grapes. It causes yellowish spots on the upper surface of leaves, with a fuzzy, purplish-gray mold-looking growth on the undersides of leaves.
6. Fusarium Wilt
Fusarium wilt is a soil-born fungal disease that affects many plants, including tomatoes, potatoes, peppers, cucumbers, eggplants, melons, and currants. It causes wilting and yellowing that eventually turns brown and dry. The plant's growth is stunted and this common plant disease eventually leads to plant death.
7. Verticillium wilt
Verticillium wilt is another soil-borne fungal disease that affects a wide range of plants, including tomatoes, peppers, and strawberries. It causes wilting, yellowing, and browning of the leaves, often starting on one side of the plant. This is a plant disease that affects the xylem, or the water-conducting parts of the plant.
8. Botrytis blight
Botrytis blight, also known as gray mold, is a fungal disease that affects a variety of plants, including flowers, vegetables, and fruits. It causes a gray, fuzzy mold on the affected plant parts, leading to rotting and decay.
9. Bacterial Spot
Bacterial spot affects various plants, including tomatoes, peppers, and beans. It causes dark, water-soaked spots on the leaves, fruits, and stems, which may eventually turn into lesions.
10. Anthracnose
Anthracnose is a fungal disease that affects many plants, including trees, fruits, and vegetables. It causes dark, sunken lesions on the stems, leaves, and fruits, leading to decay and crop loss.
Common Plant Disease Prevention & Control
It's important to note that prevention and proper plant care are essential in minimizing the occurrence and spread of common plant diseases. Overwatering plants is often the culprit for causing and spreading plant disease. Additionally, pests and insects carry and spread disease, where it can infect an open wound or an area of the plant that was recently pruned.
Tips to Prevent Common Plant Disease
- Don't over water. Allow the soil in your garden to dry out a bit between waterings so that it' remains moist but not soggy.
- Prune plants using clean and sharp sheers in order to avoid wounding the plant where disease can enter.
- Prune foliage so air can flow easily between stems, branches, and neighboring plants.
- Always disinfect your garden tools after using them - especially if they were used in a foreign garden bed.
- Improve soil health by adding organic matter.This will add beneficial microorganisms, bacteria, fungal organisms, as well as increase the flow of oxygen in the soil.
- Refresh or replace (if problem is extremely bad) diseased soil.
- Routinely nourish plants with organic fungicide and immunity boosting products.
