Powdery Mildew is a fungal plant disease that can affect a wide variety of vegetation. Its early signs can be easily detected as powdery spots appear on leaves and stems. The leaves will not discolor but will start to crinkle. The lower leaves are affected the most. As mildew progresses, the spots increase in size and in volume as spores increase in number as well. Mildew progresses very well in humid environment. The spores stay dormant until they get moisture needed for germination. The disease can infect the entire stem and all branches of your plant. If you do not treat it immediately, it will spread throughout your whole garden very quickly.
It is very important to water your plants well, way deep into the roots especially during very hot weather. Take note, avoid water from getting onto the leaves. Giving good air circulation between your plants is essential. This aids in drying up your plants a lot faster. For inactive plants, spray on them some fungicidal soap or treat with sulphur. This is best done on spring time. When mildew has affected only a few leaves, remove the infected leaves and dispose properly. You can bury, burn, or put them inside a bag and seal. Never compost infected plants because the pores can return and damage your garden again. There are a number of effective home remedies you can apply to fight mildew. Try using the baking soda spray. Below are the procedure and things needed in formulating it.
Things needed: 1 tablespoon of any brand of regular mouthwash, 1 gallon of unchlorinated water, 1 tablespoon of liquid soap, 1 tablespoon of vegetable oil, 1 large pump sprayer ,1 tablespoon of apple cider vinegar, and 1 1/2 tablespoon of baking soda.
Procedure: Mix the mouthwash, soap, oil, and baking soda with one cup of water. Then add the vinegar. You do this to avoid bubbles that can be messy. Pour this mixture into the sprayer and then add in 1 gallon of water. Then shake well. Then thoroughly spray on your plants.
You may need to spray again if it rains as the water washes it off. The baking soda spray can also be used in plants in an hydroponics garden. Spray the mixture onto your plants every two weeks, and if mildew persists and gets worse, you might need to purchase disease resistant varieties. Go to the nearest garden supplies store and inquire on what will work best for the kind of plants you are growing.
