A process and method for the production of endophytes as plant inoculant products, specifically Clonostachys rosea strain 88-710, for the promotion of plant vigor, health, growth and yield are disclosed. The endophyte, Clonostachys rosea strain 88-710 produces a fungal conidial preparation by utilizing a discrete solid substrate fermentation system, namely Potato Dextrose Agar or Malt Extract Agar. Additionally, the endophyte, Clonostachys rosea strain 88-710, can act as an inoculant to stimulate and have an additive effect with rhizobium bacteria on the production of nitrogen fixing nodules on legumes and growth enhancement e.g. beans, soybeans, peas and alfalfa. As well, Clonostachys rosea strain 88-710, can combine with rooting hormones, e.g. indole-3-butyric acid (IBA) to provide inoculant and rooting benefits to cuttings / transplants of plants.

Clonostachys rosea strains have novel usefulness as inoculants of plants promoting plant vigor, health, growth, yield and a reduction of competitive stress caused by other fungi when used alone or sequentially with many fungicides in an integrated pest management system (IPM). Seed and foliar uses are shown to inoculate and subsequently achieve endophytic colonization of the portion of the plant treated. While the germinating conidia of this organism has been shown to tolerate several fungicide groups, the established mycelium of Clonostachys rosea is significantly more tolerant to systemic fungicides facilitating use in seed and foliar applications. Seed treatment and colonization may occur at any time after harvest resulting in endophyte enhanced seed that ignores or is marginally altered by other fungal organisms and may be suitable for Feed, Food and Seed uses.
