Abstract

A synergistic agricultural formula including at least one diacyl or diaryl urea, such as a N,N′-diformylurea, and at least one mixture of nutrients, such as a mixture of micronutrients and/or macronutrients. This synergistic agricultural formula gives those skilled in the art the ability to regulate important phenotypical parameters that lead to a variety of important agronomic and horticulture traits which improve crop yield parameters leading beyond that of its individual components.

Claims (32)

1. A synergistic agricultural formula that is absorbed by the plant comprising:

30 to 0.5 wt. % diformylurea; and

0.1 to 20 wt. % at least one mixture of nutrients provided as an aqueous solution so that said nutrients may be absorbed by the plant, wherein said at least one mixture of nutrients comprises magnesium, copper, manganese and zinc as the only nutrients present in said formula and wherein said nutrients are chelated compounds;

optional oil,

optional surfactant, and

water, wherein said diformylurea and said at least one mixture of nutrients together provides synergy.

2. The synergistic agricultural formula of claim 1 , wherein said at least one mixture of nutrients includes 0.001-5 wt. % magnesium, 0.001-5 wt. % copper, 0.001-5 wt. % manganese and 0.001-5 wt. % zinc based on the total weight of the agricultural formula, and wherein the magnesium, copper, manganese, and zinc are the only nutrients present in said formula.

3. The synergistic agricultural formula of claim 1 , wherein said at least one mixture of nutrients includes 1-3 wt. % magnesium, 1-3 wt. % copper, 1-3 wt. % manganese and 1-3 wt. % zinc based on the total weight of the agricultural formula, and wherein the magnesium, copper, manganese, and zinc are the only nutrients present in said formula.

4. The synergistic agricultural formula of claim 1 , wherein the diformylurea is present in 3-8 wt. %.

5. The synergistic agricultural formula of claim 2 , wherein the diformylurea is present in 3-8 wt. %.

6. The synergistic agricultural formula of claim 3 , wherein the diformylurea is present in 3-8 wt. %.

7. A synergistic agricultural formula that is absorbed by the plant comprising:

30 to 0.5 wt. % diformylurea; and

0.1 to 20 wt. % at least one mixture of nutrients provided as an aqueous solution so that said nutrients may be absorbed by the plant, wherein said at least one mixture of nutrients is a mixture including a water soluble form of nitrogen, P 2 O 5 , K 2 O, and boron as the only nutrients in said formula;

optional oil,

optional surfactant, and

water, wherein said diformylurea and said at least one mixture of nutrients together provides synergy.

8. The synergistic agricultural formula of claim 7 , wherein said at least one mixture of nutrients includes 1-5 wt % a water soluble form of nitrogen, 1-10 wt % a water soluble form of P 2 O 5 ,1-4 wt % a water soluble form of K 2 O, and 0.01-1 wt % boron based on the total weight of the agricultural formula, wherein the nitrogen, P 2 O 5 , K 2 O, and boron are the only nutrients present in said formula.

9. The synergistic agricultural formula of claim 7 , wherein said at least one mixture of nutrients includes 2-3 wt % a water soluble form of nitrogen, 8-10 wt % a water soluble form of P 2 O 5 ,1-2 wt % a water soluble form of K 2 O, and 0.05-0.1 wt % boron micronutrient based on the total weight of the agricultural formula, wherein the nitrogen, P 2 O 5 , K 2 O, and boron are the only nutrients present in said formula.

10. The synergistic agricultural formula of claim 7 , wherein said at least one mixture of nutrients includes about 2.5 wt % a water soluble form of nitrogen, about 9 wt % a water soluble form of P 2 O 5 , about 1 wt % a water soluble form of K 2 O, and about 0.05 wt % boron based on the total weight of the agricultural formula, wherein the nitrogen, P 2 O 5 , K 2 O, and boron are the only nutrients present in said formula.

11. A synergistic agricultural formula of claim 7 , wherein the diformylurea is present in 3-8 wt. %.

12. The synergistic agricultural formula of claim 8 , wherein the diformylurea is present in 3-8 wt. %.

13. The synergistic agricultural formula of claim 9 , wherein the diformylurea is present in 3-8 wt. %.

14. The synergistic agricultural formula of claim 10 , wherein the diformylurea is present in 3-8 wt. %.

15. A synergistic agricultural formula that is absorbed by the plant consisting of:

30 to 0.5 wt. % diformylurea; and

0.1 to 20 wt. % at least one mixture of nutrients provided as an aqueous solution so that said nutrients may be absorbed by the plant, wherein said at least one mixture of nutrients comprises magnesium, copper, manganese and zinc as the only nutrients present in said formula, wherein said nutrients are chelated compounds;

optional oil,

optional surfactant, and

water.

16. The synergistic agricultural formula of claim 15 , wherein the diformylurea is present in 3-8 wt. %.

17. The synergistic agricultural formula of claim 16 , wherein said at least one mixture of nutrients includes 1-3 wt. % magnesium, 1-3 wt. % copper, 1-3 wt. % manganese and 1-3 wt. % zinc based on the total weight of the agricultural formula, wherein the magnesium, copper, manganese, and zinc are the only nutrients present in said formula.
