Synergistic herbicidal composition containing penoxsulam and oryzalin
View Patent ↗An herbicidal synergistic composition containing (a) penoxsulam and (b) oryzalin provides improved post-emergence herbicidal weed control in tree and vine crops, turf, sugar cane, range and pasture, parks and alleyways, and IVM.
1. A synergistic herbicidal composition comprising a herbicidally effective amount of (a) oryzalin and (b) penoxsulam, wherein the weight ratio of oryzalin:penoxsulam is from about 343:1 to about 536:1.
2. The composition of claim 1 , wherein the weight ratio of oryzalin:penoxsulam is about 343:1 or 536:1.
3. The composition of claim 1 further comprising an agriculturally acceptable adjuvant or carrier.
4. A method of controlling undesirable vegetation comprising contacting the vegetation or the locus thereof with a herbicidally effective amount the composition of claim 1 .
5. A method of controlling undesirable vegetation comprising contacting the vegetation or the locus thereof with a herbicidally effective amount of (a) oryzalin and (b) penoxsulam, wherein the weight ratio of oryzalin:penoxsulam is from 343:1 to 536:1.
6. The method of claim 5 , wherein the weight ratio of oryzalin:penoxsulam is about 343:1 or 536:1.
7. The method of claim 5 , wherein the undesirable vegetation is Solanum nigrum, Chenopodium album, Portulaca oleracea, Kickxia spuria , or Senecio vulgaris.
8. The method of claim 5 , wherein the undesirable vegetation is controlled in fruit trees, grapevines, turf, sugar cane, parks and alleyways, range and pasture, or industrial vegetation management.
9. The method of claim 8 , wherein the fruit tree is pome, stone, tree nut, citrus or olive.
10. The method of claim 5 , wherein the oryzalin is applied at a rate of from about 2400 gai/ha to about 4800 gai/ha and the penoxsulam is applied at a rate of from about 5.6 gai/ha to about 35 gai/ha.
11. The method of claim 9 , wherein the oryzalin is applied at a rate of about 2400 gai/ha to about 3000 gai/ha and the penoxsulam is applied at a rate of from about 5.6 gai/ha to about 7 gai/ha.
12. The method of claim 9 , wherein the penoxsulam is applied at a rate of about 5.6 gai/ha and the oryzalin is applied at a rate of about 3000 gai/ha.
13. The method of claim 5 , wherein the penoxsulam is applied at a rate of about 7 gai/ha and the oryzalin is applied at a rate of about 2400 gai/ha.
