Weed control process comprising the application of mesotrione and second herbicide
View Patent ↗A novel process for controlling weeds in a crop comprising sorghum , the process comprising the application of a herbicidally effective amount of: (i) mesotrione, and (ii) a second herbicide selected from one or more of prosulfuron, dicamba, 2, 4-D, halosulfuron-methyl and quinclorac to the locus of the weeds is disclosed.
1. A process for controlling weeds in a sorghum crop while reducing injury to such crop caused by the post-emergent application of a herbicidally effective amount of mesotrione over such crop, the process comprising applying to the locus of the weeds a herbicidally effective amount of:
(i) mesotrione, and
(ii) a second herbicide selected from prosulfuron
wherein the mesotrione is applied post-emergent over such sorghum crop.
2. A process according to claim 1 in which the mesotrione is applied at a rate of between 50 and 300 g/ha.
3. A process according to claim 1 using 0.5 to 400% of the second herbicide, based on the concentration of mesotrione.
4. A process according to claim 1 in which mesotrione and the second herbicide are applied at the same time.
5. A process according to claim 1 in which mesotrione and the second herbicide are applied sequentially.
6. A process according to claim 1 in which mesotrione and the second herbicide are applied as separate compositions.
7. A process according to claim 1 in which mesotrione and the second herbicide are applied as a single composition.
8. A process according to claim 1 in which mesotrione and the second herbicide are applied post-emergent over such sorghum crop.
