Mycostop Biofungicide — Present Status
Mycostop biofungicide is a powdery product that contains spores and mycelium of Streptomyces sp. The fungicidal effect of the product derives completely from a naturally occurring streptomycete isolated from Finnish Sphagnum peat. Mycostop biofungicide was developed by Kemira Oy in collaboration with the University of Helsinki and the Agricultural Research Centre of Finland. The manufacturer of the biofungicide and the registration holder is Kemira Oy. Mycostop can be used as a dry powder for seed dressing and as an aqueous suspension for root-dip treatments and spraying on or drenching into soil. The recommended application rate in seed dressing ranges from 2–8 g/kg of seeds and in soil drenching from 0.1 to 1 kg per hectare. Mycostop is effective against various seedborne and soilborne pathogens, especially Fusarium sp. It can be used to control wilts in ornamentals, damping-off in vegetables and ornamentals, root and foot rot in cucumber and seedling blight and ear blight in wheat. Mycostop has been commercially available in Finland since 1990, and sales permits for Hungary and Bulgaria were obtained in 1991. Apart from these countries, registration procedures have been initiated in seven European countries, the USA and Japan. Trials with mycostop are also being carried out around the world to test the efficacy of the product on various crops, against several fungal pathogens, and under different climatic conditions. So far, promising results comparable to those obtained with chemical fungicides have been achieved in many trials.
