RotGuard is a systemic fungicide used to control Phytophthora Root rot, Collar rot, Crown rot and downy mildew in citrus grapes and a range of ornamental plants.
How to use:
Use higher rate under higher disease risk conditions (e.g. for trees in heavy clay soil). Apply each year as a preventative foliar spray in late winter prior to flowering and again in autumn when fruit are approaching maturity. Spray until leaves are just wet.
