Ensure grapevine cuttings have the best start against fungal diseases by incorporating Sporekill® in propagation programs.Sporekill (120g/L didecyldimethyl ammonium chloride) is an agricultural disinfectant designed for broad spectrum sanitation. Traditionally, it has been used in horticulture packing houses and growing equipment to control a wide range of bacteria, fungi as well as viruses, mycoplasma and algae on contact. Sporekill is now registered for use on graprevine cuttings and grafting equipment used in the propagation process. It protects from key fungal diseases - bunch rot (Botryosphaeria), black foot (Cylindrocarpon), cane spot (Phomopsis), Phaemoniella and Phaeoocremonium – giving cuttings the best possible start.

HOW SPOREKILL WORKSSporekill is part of a chemistry known as Quarternary Ammonium Compound (QAC). These are used in a wide variety of household and agricultural situations including cosmetics, shampoo, food processing and dairy pasteurising plants.

QAC’s work by disrupting the proteins of the bacterial, virus or fungal cell, affecting the metabolic reactions of the cell and allowing fluid to leak from the cell, thereby causing death.

Sporekill is non-toxic, non-phytotoxic and non-corrosive at recommended rates. It is also biodegradable with no known resistance currently occurring.

Sporekill can be easily integrated into a propagation program to disinfect cuttings and cutting equipment. Performance is not affected by water pH or hardness and stays in active solution.
