Synergistic pre-emergent and post-emergent weed control compositions and methods of use thereof
Methods and compositions for synergistic pre-emergent and post-emergent weed control are disclosed. In particular, the present disclosure relates to an herbicidal composition comprising at least one pre-emergent herbicide and at least one post-emergent herbicide, wherein the pre-emergent herbicide and the post-emergent herbicide synergistically inhibit pre-emergent and post-emergent development of a weed. The disclosure further relates to herbicidal compositions comprising isoxaben, 2,4-D, mecoprop-P, and dicamba.
1. An herbicidal composition comprising a pre-emergent herbicide and post-emergent herbicide,
wherein the pre-emergent herbicide comprises isoxaben,
wherein the post-emergent herbicide comprises 2,4-D, mecoprop-P and dicamba,
wherein the isoxaben plus a mixture of the 2,4-D, mecoprop-P and dicamba exhibits synergy.
2. The herbicidal composition of claim 1 comprising:
from about 0.2 to about 25 W/W % of isoxaben;
from about 0.05 to about 35 W/W % of 2,4-D; and
from about 0.05 to about 20 W/W % of mecoprop-P.
3. The herbicidal composition of claim 1 comprising:
From about 2 to about 3 W/W % of isoxaben;
from about 3 to about 5 W/W % of 2,4-D; and
from about 0.1 to about 1 W/W % of mecoprop-P.
4. The herbicidal composition of claim 1 comprising:
from about 2.4 to 2.9 W/W % of isoxaben;
from about 3.50 to about 4.32 W/W % of 2,4-D; and
from about 0.7 to about 1.1 W/W % of mecoprop-P.
5. The herbicidal composition of claim 2 comprising from about 0.01 to about 25 W/W % of dicamba.
6. The herbicidal composition of claim 3 comprising from about 0.1 to about 0.8 W/W % of dicamba.
7. The herbicidal composition of claim 4 comprising from about 0.4 to about 0.5 W/W % of dicamba.
8. The herbicidal composition of claim 1 , wherein the pre-emergent herbicide further comprises indaziflam and the post-emergent herbicide further comprises iodosulfuron.
9. The herbicidal composition of claim 1 , wherein the pre-emergent herbicide further comprises indaziflam.
10. A method of controlling weed growth, said method comprising applying a composition according to claim 1 to a weed or seed thereof or to a field where the weeds are expected to grow.
11. The method of claim 10 wherein the weed is selected from the group consisting of: plantain, including buckhorn plantain; clover, including white clover, red clover, and rabbitfoot clover; black medic; dandelion; henbit; pigweed; purslane; spurge; false dandelion; ground ivy; wild garlic; wild onion; and wild violet.
12. The method of claim 10 , which is applied to turfgrass.
