Wheat is cultivated in soils tilled for years exposing Beauveria bassiana (Bb) to sunlight and heat, thus removing it from the landscape and at least increased difficulty for survival.  Observed areas where sawfly has become a pest, Bb is nearly extinct.  This seems true for Hessian fly regions as well.  The absence of any organism contributing to the health of its host permits challenges from new circumstances.  These new circumstances can attract or favor new patswineens.  The sawfly is bivoltine and partial univoltine.  This refers to the number of broods in a season.  Univoltine eggs can survive winter in their host and incubate with spring temperatures.  Given that scenario, it is easy to imagine an outcome without Bb providing plant resistance.

While much of the natural characteristics Beauveria bassiana offers can be substituted with other organisms, through chemical applications, or by plant genetic modification each has only a singular resolve.  This is observed contrasting organic farming to conventional practices.  Yield and quality increased with both practices. Organic without fungicides, pesticides, or application of foliar biocides demonstrated that wheat seed inoculated with Bb at planting tends to equal yields from conventional practices without applications of fungicides.  Consistent in all crops is improved germination and emergence.

The use of Beauveria bassiana is a managerial practice that has significant benefits in today’s agriculture and gardening environment.

The Beauveria bassiana in SPE 120 and SBb 2.5 is a PLANT isolate and is considered beneficial fungi.

Seed and Soil Products Protect & Strengthen Plants as They Grow

Direct contact with seed is preferred to assure plant entry at germination. Applied on, under, or atop of seed allows Beauveria bassiana competitive preference to initial plant roots where it becomes a symbiotic entophyte within the plant.
