Embodiment 1

[0135] Example 1: Laboratory Study (2006)

[0136] Example 1 describes an experimental study carried out in the spring and summer of 2006 which evaluated the effect of different commercially available fungicide seed coatings on germination in the presence and absence of alkali metal formononetinate. Effects of VAM development in maize seedlings. All corn seed coatings were manufactured by Sub-Sahara International, Inc. (now owned by Becker Underwood Inc.) using standard coating techniques. The processor used was the RP-14 Rotary Seed Coating Machine manufactured by Sedpell of Canada. Sequential applications were performed, first applying the fungicide according to label instructions and then recoating the seeds externally with alkali metal formononetinate (potassium salt) when they were dry.

[0137] The listed fungicides were applied in the amounts given in Table 4. The fungicides were applied as high viscosity liquid suspension formulations according to the correspondin...

Embodiment 2

[0150] Example 2: Laboratory Research (2007)

[0151] In the study reported in Example 1, it was determined that the most commonly used commercial fungicides used on seeds at the recommended application rates did not inhibit the development of VAM by Myconate on maize plants grown from fungicide-treated seeds stimulating effect. In addition, higher application rates of alkali metal formononetinate produced more VAM development than lower application rates.

[0152] Further studies were conducted in 2007 to determine, first, whether application rates of potassium formononetinate exceeding 1 mg / seed in the presence of the seed coating fungicide produced more High VAM colonization rate; and secondly, to determine whether the water insoluble formononetinic acid acts in the same way as the potassium salt.

[0153] METHODS: This study was conducted between February and April 2007 in the greenhouse of the Formosa Agricultural and Environmental Research Center using hybrid maize pla...

Abstract

Seed coatings and coated seeds as provided herein include at least one fungicide and at least one VAM fungus-enhancing composition. Coated seeds exhibit enhanced growth due to depression or elimination of undesirable fungi coupled with either enhanced growth of VAM fungus or lack of detrimental fungicide effect on VAM fungus.

Description

[0001] priority claim [0002] This application claims priority to US Provisional Patent Application No. 60 / 903,087, filed February 23, 2007. The entire contents of this application are hereby incorporated by reference. [0003] Background of the invention 1. Technical field [0004] Embodiments of the invention relate to coated seeds. Other embodiments of the invention relate to methods for producing coated seeds. More specifically, embodiments of the present invention relate to coated seeds obtained by coating the seeds with a fungicide and at least one alkali metal formononetinate and formononetin. Other embodiments may involve providing genetically engineered coated seeds for the production of proteins with fungicidal activity and / or vesicular arbuscular mycorrhizal (VAM) fungal enhancing components and / or any other conferring any trait protein. The coating of the present invention stimulates plant growth and yield from coated seeds by stimulating the growth of ben...
