| In vitro study | The results show that sulcotrione behaves as time-independent reversible inhibitor. Similar results are previously described for natural β-triketones, and for the synthetic β-triketone NTBC. However it is the first time that such behavior is observed using a purified hydroxyphenylpyruvate dioxygenase (HPPD) and a synthetic β-triketone, namely sulcotrione. Inhibition kinetic analysis, performing with 3 hydroxyphenylpyruvate (HPP) and sulcotrione concentrations, show that the apparent K M increasing with sulcotrione concentration. This behavior is consistent with the data present in the literature, describing sulcotrione as a competitive inhibitor of HPPD. |

2-(2-chloro-4-(methylsulfonyl)benzoyl)-1,3-cyclohexanedione - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| control object | broad-leaved weeds and some monocotyledonous weeds, such as quinoa, Solanum, Solanum nigrum, Polygonum, Polygonum cuspidatum, Polygonum, maldon, Blood Root Grass, Ceylon and wild millet. |
| method of use | application after Bud, dosage of 300 ~ 450gai/ha can control broad-leaved weeds and Gramineae weeds. High dose [900Gai/ha] was also safe for corn, but in the case of drought and low-lying water, the corn leaves had transient decolorization symptoms and had no effect on the weight of corn growth. Under normal rotation conditions, it is safe to winter wheat, barley, winter rape, potato, sugar beet and pea. Corn weeds may be controlled by single, mixed, or continuous application. |
| mechanism of action | ICIA0051 is a foliar herbicide, which can also be absorbed by root system, the residual soil activity made ICIA0051 superior to the post-emergence herbicide with only foliar activity. This additional effect is an important factor in the control of certain weeds such as amaranth. After application, the weeds were quickly decolorized and slowly died. The mode of action of the three ketone herbicides has not yet been fully understood, it is likely that the synthesis of chlorophyll is directly affected, acting on the synthesis of carotenoids. Because of this mode of action, it is unlikely to be cross-resistant to triazine herbicides. |
| biological activity | Sulcotrione is a β-trione herbicide that inhibits hydroxyphenylpyruvate dioxygenase (HPPD). |
| Target | HPPD |
| Use | for controlling annual weeds in corn field |
