Methods for improving plant growth
View Patent ↗Methods of improving the growth of a plant by applying a plant growth effective amount of a plant growth composition that includes a hydrated aluminum-magnesium silicate and at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester to plant propagation material in the absence of insect pest pressure.
1. A plant composition obtained after treatment of plant propagation material, the treatment comprising the step of applying a plant growth effective amount of a plant growth composition to the plant propagation material, said plant growth composition comprising:
a) a hydrated aluminum-magnesium silicate; and
b) at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester;
wherein the plant growth composition is free of biocides.
2. The plant composition of claim 1 , wherein the plant growth composition comprises: about 0.2% to about 20% of at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester; wherein all % are % by weight based on the total weight of all components in the composition.
3. The plant composition of claim 1 , wherein the plant propagation material is selected from the group consisting of seeds, spores, bulbs, cuttings, sets, rhizomes, tubers, meristem tissue, plant cells, and combinations of two or more thereof.
4. The plant composition of claim 3 , wherein the plant propagation material comprises at least one seed.
5. The plant composition of claim 1 , wherein the plant growth composition is applied at a rate ranging from 100 g/ha to 500 g/ha.
6. The plant composition of claim 5 , wherein the plant growth composition is applied at a rate ranging from 200 g/ha to 300 g/ha.
7. The plant composition of claim 1 , wherein the plant is selected from the group consisting of corn, cotton, soybean, sunflower, wheat, barley, rye, oat, and oilseed rape.
8. The plant composition of claim 1 , wherein the plant growth composition further comprises a liquid fertilizer.
9. The plant composition of claim 1 , further comprising an alkylpolyglycoside surfactant in about 1% to about 90%, an antifoam agent in about 0.001% to about 1%, and an antifreeze agent in about 1% to about 20%, wherein all % are % by weight based on the total weight of all components in the composition.
10. A composition suitable for use in improving the growth of a plant, the composition consisting:
a) a hydrated aluminum-magnesium silicate;
b) at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester;
c) an alkylpolyglycoside surfactant;
d) a preservative;
e) an antifoam agent;
f) an antifreeze agent; and
g) water.
