// Definition
The use of elemental sulfur products in cannabis integrated pest management, particularly for broad mite and powdery mildew control in nurseries. While ubiquitous in conventional agriculture, sulfur fungicides are controversial in cannabis because they foul the flavor of hash and flower, though they remain far safer than synthetic alternatives like Eagle 20 (myclobutanil), which generates hydrogen cyanide when heated.
// From the Episode
Discussed extensively across episodes 211 and 228 as panel members debated IPM approaches. Dr Mark notes most cannabis nurseries use sulfur because it effectively controls broad mites and powdery mildew. However, it leaves residues detectable in hash. The panel contrasts this with Eagle 20, which thermally decomposes to hydrogen cyanide — highlighting the importance of understanding pesticide chemistry in extraction. Discussion also touches on whether the sulfur compounds in skunky cannabis varieties (VSCs) might serve a natural antifungal function for the plant.
