Trichoderma strains that induce resistance to plant diseases and/or increase plant growth
First Claim
1. A method for enhancing growth of plants comprising:
- contacting a Trichoderma strain with a plant or a plant seed under conditions effective for the Trichoderma strain to colonize the roots of the plant or a plant grown from the plant seed, thereby creating a plant-Trichoderma system andgrowing the plant or plant seed under conditions effective to sustain the plant-Trichoderma system in a planting medium and to enhance plant growth, wherein the Trichoderma strain is Trichoderma harzianum strain RR17Bc (ATCC accession number PTA
9708).

Abstract
A method for enhancing growth of plants comprising contacting a Trichoderma strain with the plant or a plant seed under conditions effective for the Trichoderma strain to colonize the roots of the plant or a plant grown from the plant seed, thereby creating a plant-Trichoderma system. The plant or plant seed is grown under conditions effective to sustain the plant-Trichoderma system in a planting medium and to enhance plant growth. The Trichoderma strain is selected from the group consisting of Trichoderma atroviride strain WW10TC4 (ATCC accession number PTA 9707), Trichoderma harzianum strain RR17Bc (ATCC accession number PTA 9708), Trichoderma harzianum strain F11 Bab (ATCC accession number PTA 9709), and combinations thereof. Methods of enhancing resistance of plants to abiotic stress, increasing nitrogen use efficacy in plants, reducing nitrous oxide emissions in air, reducing leaching of nitrates into soil and water, and enhancing sequestration of carbon from air are disclosed.
