1. A composition comprising:
a capsule suspension (CS) of a mixture of chlorethoxyfos and bifenthrin in a liquid phase, the mixture being disposed within an encapsulating wall;
a polymeric dispersant;
0.01% to about 5% by dry weight microfibrillated cellulose, and optionally ethanolamine, and
a high ionic strength medium,
wherein the microfibrillated cellulose is chemically unmodified, wherein the composition exhibits time-dependent shear thinning.
2. The composition of claim 1 , wherein the encapsulating wall comprises a polyurea.
3. The composition of claim 1 , wherein the liquid phase comprises water.
4. The composition of claim 1 , further comprising ethanolamine.
5. A composition comprising:
an agricultural agent in particulate form;
a microfibrillated cellulose, wherein the microfibrillated cellulose is present in an amount from about 0.01% to about 5% by dry weight of the composition and
a high ionic strength medium;
wherein the particulate form is selected from the group consisting of a liquid droplet, a gel, or a combination thereof; and
wherein the agricultural agent in particulate form are part of an emulsifiable concentrate (EC), a capsule suspension (CS), a suspo-emulsion (SE), a microemulsion (ME), or an oil dispersion (OD),
wherein the microfibrillated cellulose is chemically unmodified, wherein the composition exhibits time-dependent shear thinning.
6. The composition of claim 5 , wherein the composition further comprises solid particulates, metamict state particulates, or combinations thereof.
7. The composition of claim 5 , further comprising a polymeric dispersant.
8. The composition of claim 5 , wherein the agricultural agent comprises one or more of a pesticide, a biological pesticide, an herbicide, an insecticide, a plant growth regulator, a biostimulant, a UV-protectant, a dust repellant, a hormone, a fertilizer, a micronutrient or combinations thereof.
9. The composition of claim 6 , wherein the solid particulate, metamict state particulates, or combinations thereof comprises one or more of a pesticide, a biological pesticide, an herbicide, an insecticide, a plant growth regulator, a biostimulant, a UV-protectant, a dust repellant, a hormone, a fertilizer, a micronutrient or combinations thereof.
10. The composition of claim 5 , wherein the agricultural agent comprises chlorethoxyfos.
11. The composition of claim 5 or 10 , wherein the agricultural agent comprises bifenthrin.
12. The composition of claim 5 , wherein the agricultural agent is present in an amount from about 0.1% to about 60% by weight of the composition.
13. The composition of claim 5 , further comprising a polymeric dispersant is selected from the group consisting of anionic polymeric dispersants, lignosulfonates, alkyl formaldehyde condensates, non-ionic polymeric dispersants, polyvinyl alcohols, and acrylic copolymers.
14. The composition of claim 13 , wherein when the agricultural agent is part of a capsule suspension, the polymeric dispersant is an acrylic comb polymeric dispersant.
15. The composition of claim 13 , wherein the polymeric dispersant is an anionic acrylic polymer.
16. The composition of claim 5 , further comprising an additional rheology modifier.
17. The composition of claim 16 , wherein the rheology modifier is selected from the group consisting of polysaccharides, xanthan gums, guar gums, locust gums, clays, silicas, starches, rheo-surfactants, and mixtures thereof.
18. The composition of claim 17 , wherein the rheology modifier is present in an amount from about 0.01% to about 5% by weight of the suspension.
19. The composition of claim 5 , further comprising ethanolamine.
20. A method of treating a crop comprising:
providing a composition comprising:
an agricultural agent in particulate form; and
a microfibrillated cellulose, wherein the microfibrillated cellulose is present in an amount from about 0.01% to about 5% by dry weight of the composition;
wherein the particulate form is selected from a liquid droplet, a gel,
an emulsifiable concentrate (EC), a capsule suspension (CS), a suspo-emulsion (SE), a microemulsion (ME), or an oil dispersion (OD); and
wherein the microfibrillated cellulose is chemically unmodified; and
adding to the composition a high ionic strength medium to provide a mixture.
