Bug Watch: Powdery mildew on vegetables
Avoid disappointing summer vegetable harvests by being on the watch for powdery mildew. Look for leaves covered with a white powder which spreads quickly and eventually kills the plant. The disease is commonly found in summer on beans, zucchini, pumpkin and tomato. Spray regularly with organic Eco-fungicide, which works in two ways. Firstly, it alters the pH of the leaf surface, inhibiting the germination of new fungal spores. Secondly it attacks the cell walls of existing fungal infections, causing dehydration and death of the fungal hyphae. Eco-fungicide also treats black spot on roses. Mix it with Eco-oil for a combined organic insecticide and fungicide.
