Synergistic herbicidal composition containing penoxsulam and oxyfluorfen
View Patent ↗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.
