PreFence

PreFenceTM
Biological Organic Fungicide

PreFence is an excellent product that provides added efficacy against root diseases in programs with RootShield® PLUS+. PreFence contains mycelium and spores of the naturally occurring bacterium Streptomyces sp. strain K61.
PreFence can be used in combination with RootShield PLUS+ (for the control of Fusarium plus other root diseases includingRhizoctoniaPythium and Phytophthora) or with CEASE and MilStop for the control of Botrytis.

Adding another bio-control agent with increased multiple modes of action will assist with the higher foliar and fruit disease pressures.
