GENERAL INFORMATION

Description

Used to control a wide range of economically important fungal and bacterial diseases.

Example pests controlled

Root and leaf diseases including Botrytis cinerea; Seedling fungal pathogens including Fusarium spp., Pythium spp. and Rhizoctonia spp.

Example applications

Vegetables; Potatoes; Top fruit; Stone fruit; Soft fruit including strawberries; Herbs; Ornamentals

Efficacy & activity

Appearance and life cycle

Life cycle consists in a cycle of several discernible phases: germination, outgrowth, multiplication and sporulation. It is a spore forming bacterium which grow to form vegetative cells which multiply and are then released
