Effective Treatments for Powdery Mildew on Plants
Powdery mildew is a common fungal disease that affects a variety of plants. To effectively treat and prevent its occurrence, consider the following three treatments, including both natural and chemical-based options.
1. 29% H2O2 and Enzymes Komplete: This natural combination works by attacking and killing the powdery mildew spores with H2O2, while the enzymes decompose the spores to prevent regrowth.
Directions: Mix 50-100ml of 29% H2O2 with 1L of water, then add 2ml of Enzymes Komplete per 1L of water.
2. Sulphur: This natural mineral has anti-fungal properties which can help control powdery mildew. However, it may leave a lingering smell.
Directions: Mix 3-5g of HollandBasics Sulphur with 1L of water.
Chemical-based treatments:
3. Physan 20: This broad-range disinfectant, fungicide, virucide, and algaecide effectively controls a variety of pathogens on hard surfaces and plants, providing overall protection for plants and greenhouses.
Directions: Mix 1 tablespoon of Physan 20 concentrate with 1 gallon of water.
4. Nova 40W: This powerful fungicide controls powdery mildew, rust, and scab on crops, protecting plants such as grapes, apples, root vegetables, ornamentals, and landscape turf.
Directions: For general plant types, including tomatoes and cannabis, mix 0.34g of Nova 40W per 1L of water or 3.4g per 10L of water.
To ensure long-term prevention, apply these treatments as part of an Integrated Pest Management (IPM) strategy during the vegetative and early flowering/fruiting stages on a weekly basis.
