Kumulus DF/Acoidal

Acoidal Organic Sulfur-Based Fungicide & Miticide

Organic Sulfur-Based Fungicide & Miticide

KUMULUS DF or Acoidal are wettable sulfur formulations used as a fungicidal control on crops and turf. Sulfur is present in a range of fine particles that provide ease of handling, good coverage, rapid action on the plants. The micro-granular formula flows readily without dust and dissolves rapidly for an easily maintained suspension.
Sulfur has multi-site activity against fungi and has been observed to inhibit respiration, disrupt proteins through cross-linking, form forming heavy metal chelates within fungal cells, and produced oxidation products.  These fungicidal properties result in the inhibition of spore germination and hyphal growth. The fungicidal activity of Kumulus is thought to also be the result of a direct effect of sulfur contact with fungal cells.

Kumulus (Acoidal) is a potent organic fungicide that kills pathogens through multiple mechanisms, thus greatly reducing the potential of resistance.
