Organic Treatment of Tomato Blight
This disease is caused by the fungus Phytophthora infestans and to kill it, you need a strong, effective fungicide.
Your local gardening store might carry an organic fungicide or blight spray. You can also make your own spray at home using simple ingredients that you can find at home.
You can make a good, organic fungicide using the following ingredients:
- 2-3 tbsp. vegetable oil
- 2-3 tbsp. baking soda
- 1-1/2 teaspoon of organic soap (make sure it contains no ammonia, phosphate or chlorine)
- 1 gallon of water
Mix the ingredients well then spray to your crops. Learn more about this homemade fungicide/insecticide here.
When spraying fungicide, spray on both sides of the leaves. You should also re-apply the fungicide every 5-7 days until all symptoms of tomato blight disappear. Remove any affected leaves and don’t eat affected fruits. Don’t save the seeds of affected fruits.
