Synergistic herbicidal composition containing penoxsulam and oxyfluorfen
Penoxsulam and oxyfluorfen synergistically control weeds in crops, especially perennial tree and vine crops, rice, cereal and grain crops, pastures, rangelands, IVM and turf. Such compositions provide improved pre-emergence residual and post-emergence burndown with residual herbicidal weed control.
1. A synergistic herbicidal mixture comprising a herbicidally effective amount of (a) penoxsulam and (b) oxyfluorfen, wherein the weight ratio of penoxsulam to oxyfluorfen is 1:7.5 to 1:191.
2. A herbicidal composition comprising a herbicidally effective amount of the synergistic herbicidal mixture of claim 1 and an agriculturally acceptable adjuvant and/or carrier.
3. A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with or applying to the soil to prevent the emergence or growth of vegetation a herbicidally effective amount of the synergistic herbicidal mixture of claim 1 .
4. The method of claim 3 , wherein the undesirable vegetation is controlled in crops.
5. The method of claim 4 , wherein the undesirable vegetation is controlled in perennial tree, vine crops, cereal crops, grain crops, pastures, rangelands, or industrial vegetation management.
6. The method of claim 4 , wherein the undesirable vegetation is controlled in tree crops or vine crops.
7. The method of claim 4 , wherein the undesirable vegetation is fleabane, marestail, malva, field madder, purslane, common lambsquarter, common heliotrope, or black nightshade.
8. The method of claim 3 , wherein the synergistic herbicidal mixture is applied at an application rate of between about 79 g/ha and about 2340 g/ha based on the total amount of penoxsulam and oxyfluorfen.
9. The method of claim 8 , wherein penoxsulam is applied at a rate of about 4 g/ha to 100 g/ha and oxyfluorfen is applied at a rate of between about 75 g/ha and about 2240 g/ha.
10. The method of claim 9 , wherein penoxsulam is applied at a rate of about 5 g/ha and 50 g/ha and oxyfluorfen is applied at a rate of about 100 g/ha and 2240 g/ha.
