Benefits & Features

A microbial soil inoculant that contains both Trichoderma harzianum strain T-22 and Trichoderma virens strain G-41. R.S.S.I. augments the natural microbial activity in the soil, increasing the availability of nutrients to the growing plant. Available in granules to mix with soil media, or as a wettable powder that can be drenched on all types of vegetables, ornamentals and forest tree seedlings and can enhance plant growth and quality. Because R.S.S.I. is a soil inoculant, it is not EPA registered.
