No gardener likes to deal with diseases, and bacterial leaf spots are a particularly nasty problem because there is no cure. There are ways to slow the spread, but once your plant is near, there is no way to protect it from its fate.
If you are wondering if your plant is facing a tragic death, then keep reading to learn about bacterial leaf spots.
What is a bacterial leaf spot?
Bacterial leaf spot is a plant disease that causes spots, often soaked with water, which spreads to the leaves of plants. Spots may be yellow, brown or black. Infections start small, appearing only on the leaf, fruit, or stem.
The bacteria is found on an opening in the plant. It then spreads rapidly to the rest of the plants and then to other plants in your garden.
It can occupy a large part of your garden, killing many plants. The disease spreads even more rapidly in hot, moist conditions and when a gardener uses overhead watering instead of drip irrigation.
What causes bacterial leaf spots
Bacterial leaf spots are caused by microbes that attack your plant. While the symptoms are often similar, there are many bacteria that cause disease.
Common generations include: Arvinia, Xanthomonas, Pseudomonas, Corynebacterium, And Agrobacterium.
It most often spreads in wet, hot conditions, which encourages bacteria formation and allows the disease to spread rapidly to plants in your garden.
When temperatures are between 77–86 ° F, the bacteria rapidly divide and multiply, only taking hours to double in number.
It spreads fastest during the summer months when it is hot outside, and the moisture runs out. If you use an overhead sprinkler to water your plants, it contains enough moisture to spread the infection.
It does not require too much moisture to spread. All it takes is for bacteria to splash on leaves from the soil.
The speed with which the disease spreads is why the infection rate is so high as it traces your garden.
Once the disease takes hold, it molests the entire health of your leaf.
Symptoms of bacterial leaf spot
The problem with bacterial leaf spots is that it shows plants in many different ways, making the disease difficult to identify.
Some of the symptoms of bacterial leaf spots include:
- Dark wounds on leaves
- Brown spots with yellow spots on the leaves
- Light and dark areas throughout the region
- Leafy brown edges
- Papaya, dried leaves that break easily.
These spots are usually irregular and are 3/16 and 1/2 inch wide. It occurs on all leaves, whether they are at the top of the lower part of the plant. When clusters of spots are formed on the leaves, they kill the leaf tissue.
While the disease attacks all leaves, it is most common on older leaves, especially when it turns the leaves towards papaya. It spreads rapidly, so new leaves are protected for a short time.
Common plants for bacterial leaf spots
No plant is safe from this disease. It likes ornamental and edible plants, but some of the most common hosts are:
- The beat
- black pepper
- Stone fruit trees, such as apricots, peaches, plum and cherries
- black pepper
The bacterial leaf also infects some annual and perennial flowers, but not as often as they infect vegetative plants and fruit trees. Some common flowers that attack it include:
- Purple cone flowers
- Black eyed susan
How to prevent bacterial leaf spots
Prevention is the best course of action when it comes to this garden disease. Bacterial leaf spot is hard to treat, but there are many preventive measures that prevent disease from making your garden your new home.
1. Plant Resistant Seeds
Planting of preventive seeds is the first preventive measure. Some seeds are resistant to specific bacteria, so be sure to read the description of plants or seeds before purchasing them.
2. Rotate the crops
Many diseases, including bacterial leaf spots, remain in the soil for years, so rotating your crops is essential. Some crops are more likely to fight the disease, and others are weaker.
3. Water at the base
Never over water; Water on the leaf encourages the spread of bacteria. We cannot control the rain, but we can control the water. Always water your plants at the base.
If the bacteria live in soil and water with a sprinkler, it spreads on your plant, it can become infected. This is so easy, so always avoid sprinklers. Drip irrigation system is the way to go.
4. Remove Plant Debris
Plant debris makes a home for bacteria to live, even if the plants are disease-free. Removal of plant debris is even more important when plants are infected with a disease.
5. Spread the country
Always cover a thick layer of mulch under your plants and trees to cover the soil. There are many benefits of the country in the garden, but when it comes to this disease, it stops the water from splashing the soil on your leaves.
6. Prune and Stake Plants Regularly
Always plant large plants like tomatoes at stake, which is likely to stick and touch the ground. The leaves need to stay away from the ground where the bacteria live.
Pruning is an important step to prevent bacterial leaf spots. This improves air circulation around your trees and plants.
Always disinfect your sorting equipment after each cut using a mixture of one part bleach and four parts water. You do not want to spread the bacteria to a healthy plant.
How to treat bacterial leaf spots
Bacterial leaf spots are hard to treat, but there are some ways to try. As it spreads rapidly, treatment needs to happen immediately. The delay in treatment causes the entire garden to die if left alone.
Unfortunately, these plants usually need to be removed from your garden to prevent them from spreading. Never fertilize plants that are infected with diseases; They will infect your entire compost.
1. Diffusion of copper fungicides
One treatment method is using copper fungicide spray on crops. It is effective only if it is applied early in the disease cycle. If the disease has increased, do not expect this work.
Copper spray can stop the spread of this bacteria when used weekly, but will not completely get rid of it.
2. Try Baking Soda Solution
Some gardeners say that baking soda solution works well to prevent spills. Mix one tablespoon baking soda, 2 1/2 teaspoons vegetable oil and one teaspoon liquid dish soap in one gallon of water.
Use it when you see symptoms of the disease. Spray every two weeks to help prevent progression.
Some plants get burnt when exposed to baking soda, so make sure to try just once or twice before spraying your entire plant.
3. Neem Oil
Another option is that neem oil is used to prevent the spread of bacterial leaf spots. Remember, you will not be able to get rid of it completely, so slowing down the spread is the best bet.
Neem oil is one of the best treatment sprays available for organic gardeners at all times. It treats and prevents a range of common problems that planters face.
4. Try Copper and Pyrethrin
A safe treatment method for many fungal diseases and pests is Bonide Garden Dust, which is a combination of copper and pyrethrin. Cover the top and underslide of the leaves with a uniform layer of dust. Repeat the application every 7-10 days or as needed.
Bacterial leaf spots are one of the most troublesome diseases to experience in your garden. With no real cure or treatment, it spreads rapidly through the gardens, removing plants left and right.
