Methods and compositions for controlling fungus and fungal spores and improving plant quality
View Patent ↗Methods and compositions for controlling or reducing fungal spores in a plant or crop. The disclosure further provides for compositions and methods of improving turfgrass and/or ornamental grass quality.
1. A method for controlling fungus in a plant comprising applying a synergistic combination of hydrolase and a peroxide to a plant or habitat thereof to thereby control the fungus, wherein the plant is turfgrass.
2. The method according to claim 1 , comprising applying concurrently to the plant or habitat thereof a composition comprising a mixture of the hydrolase and the peroxide.
3. The method according to claim 1 , comprising applying sequentially to the plant or habitat thereof a composition comprising the hydrolase followed by a composition comprising the peroxide.
4. The method according to claim 1 , comprising applying sequentially to the plant or habitat thereof a composition comprising the peroxide followed by a composition comprising the hydrolase.
5. The method according to claim 1 , wherein the peroxide is hydrogen peroxide.
6. The method according to claim 1 , wherein the hydrolase is present at a concentration of 0.0001% to 10% v/v concentration.
7. The method according to claim 1 , wherein the peroxide is present at a concentration of 0.0001% to 10% v/v concentration.
8. The method according to claim 1 , wherein the weight ratio of the hydrolase to the peroxide is from 1:50 to 50:1.
9. The method according to claim 1 , wherein the fungus is from the genus Pythium.
10. The method according to claim 1 , wherein the fungus is Pythium aphanidermatum.
11. The method according to claim 1 , wherein the fungus is Pythium ultimum.
12. The method according to claim 1 , wherein the turfgrass is St. Augustine grass, bermudagrass, bahiagrass, buffalograss, centipedegrass, Kentucky bluegrass, fine fescue, tall fescue, perennial ryegrass, creeping bentgrass, zoysiagraoss, crabgrass, guineagrass, pangolagrass, torpedograss, or tropical carpetgrass.
13. The method according to claim 1 , wherein the treated plants are infected with a fungus from the genus Pythium.
14. The method according to claim 1 , wherein the hydrolase and the peroxide are the only active agents.
15. The method according to claim 1 , wherein the weight ratio of the hydrolase to the peroxide is from 1:5 to 5:1.
16. The method according to claim 1 , wherein the hydrolase is present at a concentration of 0.005% to 1% v/v concentration and the peroxide is present at a concentration of 0.001% to 0.1% v/v concentration.
17. A composition for controlling fungus in a plant, comprising a synergistic combination of a hydrolase and a peroxide, wherein the hydrolase is present at a concentration of 0.005 to 1% v/v concentration and the peroxide is present at a concentration of 0.001 to 0.1% v/v concentration.
18. The synergistic composition according to claim 17 , wherein the hydrolase and the peroxide are the only active agents.
