Graph-Ex SA™ for Dry Beans is an inoculant, or seed treatment, containing a specially formulated blend of Excalibre® Dry Beans Inoculant plus SabrEx™ Root Inoculant formulated in a talc-graphite carrier. Graph-Ex SA™ is comprised of both beneficial bacteria (Rhizobia) and beneficial fungi (Trichoderma) that provide a more efficient use of soil nutrients for the host plant.
What are Rhizobia and how do they work?
Rhizobia are soil bacteria that fix nitrogen after becoming established inside root nodules of legumes. Rhizobia require a plant host; they cannot independently fix nitrogen.
At ABM, our proprietary Rhizobia for dry beans is specific to these crops in helping the plant to establish nitrogen fixing nodules that will convert atmospheric nitrogen to nitrogen that is useable by the plant. The Rhizobia in Graph-Ex SA™ for Dry Beans is a different type of Rhizobia than is used for soybeans.
What does the SA mean?
The SA means that ABM has also added our proprietary, patent pending Trichoderma strain found in SabrEx root inoculant found to be beneficial in dry bean production.
What is Trichoderma and how does it work?
Trichoderma is a fungi that is found in soils all over the world. There are thousands of known Trichoderma strains but only a few are beneficial to plants. Trichoderma colonizes with the plants root system and develops a symbiotic relationship with the plant. The Trichoderma feed from the starches and sugars produced by the plant while exuding beneficial enzymes and proteins for the host plants use. As a result the plant produces a larger root system, improves resistance to stresses such as diseases, and improves its nitrogen and water use efficiency, thus resulting in higher yields.
ABM, in working with Dr. Gary Harman of Cornell University, has developed the technology to isolate and identify specific strains of beneficial Trichoderma. Once the strains are identified and isolated, ABM tests each strain with various crops to determine which crop receives the most benefit from each strain of Trichoderma. After thorough testing, a formulation is produced and brought to market to benefit farmers.
