Choose PM-resistant cultivarsChoose PM-resistant cultivars and provide enough space between plants so that each has plenty of air circulation. Keep up with weeding to reduce plant stress. Use soaker hoses. Avoid overfertilizing. There are fungicides for PM used as protectants (preventatives) and those for eradicating the disease once it appears; some offer both. Make sure that you choose one that is safe for pumpkins. Some strains of PM are resistant to fungicides. Fungicides include: Sulfur. Neem oil solutions. Jojoba oil. Copper sprays. A solution of about 1 tablespoon baking soda and 1 tablespoon horticultural oil in 1 gallon water; baking soda solution without the oil is not as effective. Potassium bicarbonate is said to work even better than baking soda (sodium bicarbonate); you can find fungicides with potassium bicarbonate in garden centers; certain concentrations, however, can injure plants; baking soda, if used a lot, can affect soil structure. Ask your local garden center for recommendations.
