A large part of treating watermelon anthracnose involves prevention. Plant certified disease free seed, and rotate watermelon plantings with non-cucurbits every three years. It's also a good idea to apply preventative fungicide to existent vines.

How do you control anthracnose?
How to Control Anthracnose
- Remove and destroy any infected plants in your garden. For trees, prune out the dead wood and destroy the infected leaves.
- You can try spraying your plants with a copper-based fungicide, though be careful because copper can build up to toxic levels in the soil for earthworms and microbes.
What fungicide is used for anthracnose?
The most effective fungicides for control are the protective fungicides containing chlorothalonil e.g., Daconil), copper sprays containing copper diammonia diacetate (e.g., Liquicop), propiconazole (e.g., Banner Maxx II), and the systemic fungicide thiophanate-methyl (e.g., Cleary's 3336, for professional use only).
How do you treat watermelon disease?
Control is difficult, but copper fungicides can be effective if used as soon as gummy stem blight appears. Powdery Mildew – One of the most common diseases of plants in general, powdery mildew doesn't spare watermelons.
How do you treat watermelon fungus?
Management: Because watermelon varieties and hybrids are all susceptible to powdery mildew, fungicide sprays are required to control this disease. Preventive spray programs with fungicides can be effective, but the fungus readily develops fungicide resistance, often within a single season.
Does anthracnose stay in soil?
Anthracnose spores can live in soil for three to nine months, even without an infected plant nearby. In the soil, spores travel and spread through the movement of water, such as morning dew, runoff, irrigation, or rainfall.
Can anthracnose kill trees?
In general, anthracnose diseases do not kill trees, but repeated infections can weaken trees to other problems. Some defoliation may occur, but refoliation with healthy leaves follows in warmer weather. Concentrate on boosting tree vitality, which promotes new growth.
What does anthracnose look like?
What does anthracnose look like? Symptoms of anthracnose vary from host to host, but in general, include irregular spots, and dead areas on leaves that often follow the veins of the leaves. Affected tissue can vary in color, but is often tan or brown. Severely affected leaves often curl and may fall off.
How is anthracnose transmitted?
How does it spread? This fungus can be seed-borne and carry over on crop residue in the soil. It is spread in water droplets and worse in warm, humid weather. Rockmelon, honeydew, tomato, chilli, capsicum, avocado, citrus, mango, cashew, passionfruit, banana and most other tropical crops.
What are the symptoms of anthracnose?
Symptoms include sunken spots or lesions (blight) of various colours in leaves, stems, fruits, or flowers, and some infections form cankers on twigs and branches. The severity of the infection depends on both the causative agent and the infected species and can range from mere unsightliness to death.
What diseases can watermelon have?
Watermelon Foliar Diseases
- Bacterial Fruit Blotch.
- Anthracnose.
- Gummy Stem Blight.
- Downy Mildew.
- Alternaria Leaf Spot.
- Cercospora Leaf Spot.
- Myrothecium Leaf Spot.
- Powdery Mildew.
How do you control wilt in watermelon?
The best control for Fusarium wilt of watermelons is the use of resistant varieties coupled with crop rotation. Long rotations (five years or more) may lessen the survival rate of the fungus spores in the soil and decrease the severity of symptoms.
What's the best fertilizer for watermelons?
Once flowering begins, use a fertilizer with less nitrogen and more phosphorus and potassium, such as African violet food or liquid seaweed. Some believe that pinching off a vine's growing shoots as watermelons start to ripen will cause the plant to divert all its energies to fruit ripening.
