Abstract
Official abstract text for this publication.
The present invention relates to a method of controlling weeds using mixtures of HPPD inhibiting herbicides and plant growth regulators. It also relates to mixtures of HPPD inhibiting herbicides and plant growth regulators per se, and compositions comprising the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for controlling weeds, comprising applying to the weeds or to the locus of the weeds, a mixture comprising a synergistically effective amount of (i) at least one HPPD inhibiting herbicide (A) selected from the group consisting of mesotrione and a compound of formula I and (ii) trinexapac-ethyl (B) with a weight ratio of A:B of from about 1:1 to about 1:16. 2. A method according to claim 1 , wherein the weeds are monocotyledonous plants. 3. A method according to claim 1 , wherein the herbicide is mesotrione. 4. A method according to claim 1 , wherein the herbicide is a compound of formula (I). 5. A method according to claim 1 , wherein the composition is applied at an application rate of from about 0.001 kg ai/ha to about 5.0 kg ai/ha. 6. A method according to claim 1 , wherein the composition is applied at an application rate of from about 0.01 kg ai/ha to about 3.0 kg ai/ha. 7. A method according to claim 1 , wherein the composition is applied at an application rate of from about 0.05 kg ai/ha to about 0.3 kg ai/ha. 8. A method according to claim 4 , wherein the compound of formula (I) (A) and the trinexapac-ethyl (B) are present at a weight ratio of A:B of from about 1:4 to about 1:16. 9. A herbicidal composition comprising a synergistically effective amount of (i) at least one HPPD inhibiting herbicide (A) selected from the group consisting of mesotrione and a compound of formula I and (ii) trinexapac-ethyl (B) with a weight ratio of A:B of from about 1:1 to about 1:16. 10. A herbicidal composition according to claim 9 , wherein the HPPD inhibiting herbicide is a compound of formula (I). 11. A herbicidal composition according to claim 9 , wherein the herbicide is mesotrione. 12. A herbicidal composition according to claim 11 , wherein the mesotrione and the trinexapac-ethyl are present at a weight ratio of from about 1:3 to about 1:6. 13. A herbicidal composition according to claim 9 , wherein the at least one HPPD inhibiting herbicide (A) and the trinexapac-ethyl (B) are present at a weight ratio of A:B of from about 1:1 to about 1:10. 14. A herbicidal composition according to claim 10 , wherein the compound of formula (I) (A) and the trinexapac-ethyl (B) are present at a weight ratio of A:B of from about 1:4 to about 1:16.
