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.

Claims

1. A coated seed comprising:

(a) a seed;

(b) a coating comprising at least one fungicide that is a quinone outside inhibitor (QoI) fungicide; and

at least one compound selected from the group consisting of an isoflavone and an isoflavonoid.

2. The coated seed of claim 1, wherein said compound is selected from the group consisting of hesperetin, formononetin, alkali formononetinate, and mixtures thereof.

3. The coated seed of claim 1, wherein said coating further comprises an insecticide selected from the group consisting of biological/fermentation products, Agrobacterium radiobacter;

Bacillus strains;

Burkholderia cepacia;

Pseudomonas strains;

Trichoderma strains;

Streptomyces strains;

carbamates, chloronicotinyls, diacylhydrazines, neonicotinoids, nitroguanidines, organophosphates, oxadiazine derivatives, phenyl pyrazones, pyrazones, pyrethrins, pyrrols, synthetic pyrethroids, thianicotinyls and triazoles.

4. The coated seed of claim 1, wherein said fungicide and said compound are applied as a co-formulation.

5. The coated seed of claim 1, wherein said fungicide and said compound are applied consecutively or simultaneously.

6. The coated seed of claim 1, wherein said compound is an isoflavone, and said isoflavone is an alkali formononetinate selected from the group consisting of sodium formononetinate and potassium formononetinate.

13. The coated seed of claim 1, wherein said fungicide is azoxystrobin.

7. A process for producing a coated seed, comprising:

(a) providing a seed;

(b) coating said seed with at least one fungicide that is a quinone outside inhibitor (QoI) fungicide; and

(c) coating said seed with at least one compound selected from the group consisting of an isoflavone and an isoflavonoid.

8. The process of claim 7, wherein said compound is selected from the group consisting of hesperetin, formononetin, alkali formononetinate, and mixtures thereof.

9. The process of claim 7, further comprising coating said seed with an insecticide selected from the group consisting of biological/fermentation products, Agrobacterium radiobacter;

Bacillus strains;

Burkholderia cepacia;

Pseudomonas strains;

Trichoderma strains;

Streptomyces strains;

carbamates, chloronicotinyls, diacylhydrazines, neonicotinoids, nitroguanidines, organophosphates, oxadiazine derivatives, phenyl pyrazones, pyrazones, pyrethrins, pyrrols, synthetic pyrethroids, thianicotinyls and triazoles.

10. The process of claim 7, wherein the coating steps occur consecutively or simultaneously.

11. The process of claim 7, wherein said fungicide and said compound are applied as a co-formulation.

12. The process of claim 7, wherein said compound is an alkali formononetinate selected from the group consisting of sodium formononetinate and potassium formononetinate.

14. The process of claim 7, wherein said fungicide is azoxystrobin.
