MAZAO REGAIN® is a bio-fungicide containing Bacillus subtilis for the control of Powdery Mildew. Bacilllus subtilis is a ubiquitous gram-positive bacterium. It is isolated from the soil and formulated as a bio-fungicide for the control of powdery mildew. In addition, Mazao Regain contains properties that promote plant growth hence classified as a bio fertilizer. The mode of action for Regain is that it controls powdery mildew by inhibiting spore germination, disrupting the germ tube growth and interfering with the attachment of the pathogen to the plant. To obtain best results with Mazao Regain, start treatments early before disease pressures are too high. It is applied at the rate of 2L/ha weekly if powdery mildew pressures are high or if you are dealing with a highly susceptible variety. Spray fortnightly if the pressures are medium to low. Alternating Regain with sulphur compounds can both prevent and cure powdery mildew
