Because it targets the cellular processes of the pathogen rather than the plant, it presents a low risk of resistance development, a common issue with conventional chemical treatments. By applying neem oil as a dormant spray during the winter or early spring, gardeners can eliminate overwintering fungal spores on buds and bark, establishing a clean slate for the growing season.
Safe Plant Tissue Protection with Neem Oil Fungicide
Test the solution on a small part of the plant to check for phytotoxicity. Avoid application during peak heat hours to protect plant tissue.
Mode of Action Against Pathogens Unlike systemic fungicides that are absorbed into the plant's vascular system, neem oil primarily works on contact and suffocation. When applied to plant surfaces, the oil creates a protective barrier that suffocates existing fungal spores by blocking their oxygen intake.
