Claims
- 1. A composition for application to chlorophyl-containing algae or plants comprising (a) endothall or a salt thereof, (b) an ammonium salt, (c) a glutamine synthetase inhibitor, and optionally, (d) a surface active agent.
- 2. The composition of claim 1 wherein the ammonium salt is ammonium chloride, ammonium nitrite, ammonium sulfate or ammonium phosphate.
- 3. The composition of claim 1 wherein the glutamine synthetase inhibitor is methionine sulfoxine, tabatoxine-B-lactim, phosphinothricins, oxetin or 5,5-hydroxylsine.
- 4. The composition of claim 1 wherein the glutamine synthetase inhibitor is glufosinate.
- 5. The composition of claim 1 wherein the surface active agent is a surfactant.
- 6. The composition of claim 1 in a solution suitable for spray application to the algae or plant comprising
- (a) 0.1 to 0.6 percent based on the weight of the total formulation, of endothall or a salt thereof,
- (b) 0.1 to 6 percent based on the weight of the total formulation, of an ammonium salt,
- (c) 50 to 400 ppm of a glutamine synthetase inhibitor, and
- (d) 0 to 6 percent based on the weight of the total formulation, of an surface active agent.
- 7. The composition of claim 1 in formulation wherein for each part of endothall the formulation contains 5 to 15 parts of a ammonium salt, 0.05-0.5 parts of a glutamine synthetase inhibitor, and 0 to 15 parts of a surface active agent.
- 8. A method of increasing the desiccation effectiveness of endothall or a salt thereof when applied to chlorophyl-containing plants, the method comprising to the plant concurrently therewith an effective amount of (a) an ammonium salt, (b) a glutamine synthetase inhibitor, and optionally, a surface active agent.
- 9. The method of claim 8 wherein the ammonium salt is ammonium chloride, ammonium nitrite, ammonium sulfate or ammonium phosphate.
- 10. The method of claim 8 wherein the glutamine synthetase inhibitor is methionine sulfoxine, tabatoxine-B-lactim, phosphinothricins, oxetin or 5,5-hydroxylsine.
- 11. The method of claim 8 wherein the glutamine synthetase inhibitor is glufosinate.
- 12. The method of claim 8 wherein the surface active agent is a surfactant.
- 13. The method of claim 8 wherein the composition is in a solution suitable for spray application to the algae or plant comprising
- (a) 0.1 to 0.6 percent based on the weight of the total formulation, of endothall or a salt thereof,
- (b) 0.1 to 6 percent based on the weight of the total formulation, of an ammonium salt,
- (c) 50 to 400 ppm of a glutamine synthetase inhibitor, and
- (d) 0 to 6 percent based on the weight of the total formulation, of an surface active agent.
- 14. The method of claim 8 wherein the composition is a formulation wherein for each part of endothall the formulation contains 5 to 15 parts of a ammonium salt, 0.05-0.5 parts of a glutamine synthetase inhibitor, and 0 to 15 parts of a surface active agent.
- 15. The method of claim 8 wherein the plant is cotton, potato vine, alfalfa or clover.
