RTI Mycorrhizal Innoculant

Biological and Biostimulant Recommendations for Giant Pumpkin Growers RTI does not blend in additional biostimulants We currently offer just the straight goods. Blending would dilute the concentration of mycorrhizal infectivity. Many of these amendments and bio-agents are extremely valuable to your cultural practice, but we recommend that you get the products from credible sources.

You can find trichoderma, streptomyces and bacillus under the fingernails of most four year olds after a day in the park. That does not mean they are beneficial selections for use in crop production.

Reliable suppliers with a history of customer satisfaction are the best source. The following is a list of products or soil amendments that are known to be compatible or synergistic when combined with Symbios Pumpkin Pro.

Humic acids: Function primarily as chelating agents, particularly with phosphorus.
bBoth Leonardite and Rutile Kelp Products: A source of cytokinin like materials that enhance root and shoot division. Can produce synergistic effects when combined with mycorrhizae.
Unrefined kelp meals and powders are a good food source for other “Root Growth Promoting Rhizobacteria” or “RGPR’s”. The more refined products are concentrated sources of cytokinin and some must be registered as “Plant Growth Regulators”.
Maxi-crop, Acadian and North American Kelp products are all compatible / possibly synergistic when used with Symbios.
Trichoderma: Certain isolates are registered or known to be “Pathogen Antagonists” or organisms that feed on botrytis, fusarium and penicillium organisms. (Symbios has been tested and is compatible with Bioworks/ Rootshield and JH Biotech/Promote )
Streptomyces: Actinovate (Streptomyces lydicus) is an EPA registered bio fungicide proven to be effective against pythium, rhizoctonia, phytophthera, sclerotinia and powdery mildew.

It is compatible with Symbios.
Compost teas: A properly brewed compost tea full of a plethora of soil fungi (not mycorrhizae) and bacteria should produce synergistic effects when Symbios is present in the soil.
Natural fertilizers: Soluble agricultural fertilizers are high in salt and can reduce populations of beneficial soil organisms.
