(IN201917017749) 1. An aqueous composition comprising a peracid and a polyoxyethylene alkylether carboxylic acid or a salt thereof. 2. The composition of claim 1, wherein the peracid is peracetic acid. 3. The composition of claim 1, wherein the peracetic acid is an aqueous equilibrium solution comprising a weight ratio of peracetic acid:hydrogen peroxide between 1:0.01 to 1:14 and a weight ratio of peracetic acid:acetic acid between 1:0.2 to 1:19. 4. The method of claim 1, wherein the peracetic acid concentration is from about 3000 ppm to about 25,000 ppm. 5. The composition of claim 1, wherein the polyoxyethylene alkylether carboxylic acid concentration is from about 250 ppm to about 25,000 ppm. 6. A method of reducing the level of a pathogenic microorganism in an agricultural medium, the method comprising applying the aqueous composition of claim 1 to the agricultural medium at a concentration and for a time sufficient to reduce the levels of the microorganism in the agricultural medium. 7. The method of claim 6, wherein the pathogenic microorganism is selected from the group consisting of nematodes, bacteria and fungi. 8. The method of claim 7, wherein the nematode is selected from the group consisting of root knot nematodes, cyst nematodes, root lesion nematodes, and burrowing nematodes. 9. The method of claim 7, wherein the bacteria comprises a spore forming bacteria. 10. The method of claim 6, wherein the agricultural medium comprises soil, sand, or a synthetic growth medium. 11. The method of claim 6, wherein the contacting step comprises spraying, drenching, injecting, sprinkling or infusing the composition into the agricultural medium. 12. The method of claim 6, wherein the aqueous solution is applied at about 1.5 mL/cm2 of agricultural medium.
