Soil application of crop protection agents
The disclosure relates to systems, compositions and methods for providing nutrients, root proliferants, crop protection agents and other crop inputs for a plant. The disclosure also relates to methods for increasing the uptake of a crop active compound into a growing plant.
1. A method of increasing yield of a crop in a field, the method comprising providing an agricultural composition during planting of the crop seed in the field, wherein the agricultural composition comprises
a. a root proliferant component, wherein the root proliferant releases about 70-90 cumulative % of phosphate between about 30-90 days into soil after planting the crop seed and comprises about 0.002 to about 2.0 grams of phosphate; and
b. a crop protection agent, wherein the crop protection agent is released into soil such that about 70-90 cumulative % of the crop protection agent is available to the crop during about 20-100 days after planting the crop seed and the uptake of the crop protection agent by the crop is increased due to the presence of the root proliferant;
wherein the agricultural composition comprises a biodegradable polymer layer having a water permeability of about 1 to about 2000 g/m 2 /day at 25 degrees Celsius and thereby increasing the yield of the crop.
2. The method of claim 1 , wherein the crop is selected from the group consisting of maize, soybean, wheat, rice, cotton, sorghum, millet and barley.
3. The method of claim 1 , wherein the root proliferant is selected from the group consisting of dicalcium phosphate dehydrate, ammonium phosphate, magnesium ammonium phosphate, and a combination thereof.
4. The method of claim 1 , wherein the agricultural composition is provided at planting of the crop seed or prior to planting the crop seed.
5. The method of claim 1 , wherein the soil is classified as a soil type that has a lower water holding capacity.
6. The method of claim 1 wherein the crop protection agent is selected from the group consisting of an insecticide, a fungicide, a nematicide, a herbicide, a biological component and a combination thereof.
7. The method of claim 1 , wherein the crop protection agent is selected from the group consisting of an anthranilic diamide insecticide, a neonicotinoid insecticide and a combination thereof.
8. The method of claim 7 , wherein the neonicotinoid insecticide is released into the soil such that an effective amount of the insecticide is present in the soil when the target pest is present in the field during later developmental stages of the crop.
9. The method of claim 7 , wherein the anthranilic diamide insecticide is released into the soil such that an effective amount of about 5-60 g/hectare is present in the soil after about 20-100 days from providing the agricultural composition in the field.
10. The method of claim 1 , wherein the field is characterized by the presence of one or more late season pests that target maize, soybeans, rice, wheat, sorghum, barley, millet, canola or cotton.
11. The method of claim 10 , wherein the mid to late season pest is corn root worm, corn ear worm, fall army worm or a combination thereof.
12. The method of claim 1 , wherein the crop protection composition is selected from the group consisting of, thiamethoxam, clothianidin, imidacloprid, thiodicarb, carbaryl, chlorantraniliprole, cyantraniliprole, methiocarb, thiram, azoxystrobin, paclobutrazol, acibenzolar-S-methyl, chlorothalonil, mandipropamid, thiabendazole, chlorothalonil, triadimenol, cyprodinil, penconazole, boscalid, bixafen, fluopyram, fluazaindolizine, oxathiapiprolin, penthiopyrad, fenpropidin, fluxapyroxad, penflufen, fluoxastrobin, kresoxim-methyl, benthiavalicarb, benthiavalicarb-isopropyl, dimethomorph, flusulfamide, methyl thiophanate, ipconazole, prothiaconazole, sulfoxaflor, triticonazole, flutriafol, thiram, carboxin, carbendazim and a combination thereof.
13. The method of claim 1 , wherein the crop is maize and the yield increase in the field is about 10% to about 50% compared to a control field wherein a control fertilizer component comprising a normal release profile of nitrogen is applied, wherein both the fertilizer component and the control fertilizer component comprise substantially the same total nitrogen amount at planting.
14. The method of claim 1 , wherein the crop is maize and the crop seed is planted at a planting density of about 15,000 to about 70,000 plants per acre at a row spacing of about 15 inches to about 40 inches.
