Benzobicyclon (Synonyms: 苯并双环酮)
Benzobicyclon 是一种 4-HPPD 抑制剂和除草剂,与水反应后形成活性除草剂苯并双环素水解物,导致杂草的白化和死亡。Benzobicyclon 对禾本科、莎草科和阔叶杂草有效。Benzobicyclon 能有效针对磺酰脲除草剂抗性生物型以及野生型杂草。
生物活性
Benzobicyclon is a 4-HPPD inhibitor and herbicide that reacts with water to form a hydrolysate of the active herbicide benzobicycline, causing bleaching and death of weeds. Benzobicyclon is effective against grass, sedge and broadleaf weeds. Benzobicyclon effectively targets sulfonylurea herbicide-resistant biotypes as well as wild-type weeds[1][2].

4-HPPD[1]
体外研究(In Vitro)
Benzobicyclon (100-300 g a.i./ha; 1 L or 2 L) exhibits excellent herbicidal activity against S. juncoides regardless of the emergence depth between 0 and 3 cm and (200-300 g a.i./ha; pre-emergence; 1 L) hardly affected by the soil types[1].
Benzobicyclon (300 g a.i./ha; 1-leaf and 1 L stages) completely controls S. juncoides at 25°C, 20°C, and 15°C, and takes longer to reach 90% control at low temperatures[1].
Benzobicyclon (200, 300 g a.i./ha; pre-emergence and 1 L stages) exhibits excellent herbicidal activity against all SU-R biotypes S. juncoides, M. vaginalis and L. dubia as well as SU-S biotypes. (SU-S: sulfonylurea herbicide-susceptible, SU-R: sulfonylurea herbicide-resistant)[1].
Benzobicyclon (200-600 g a.i./ha; pre-emergence and 1 L stages) exhibits excellent herbicidal activity against E. crus-galli , S. juncoides, M. vaginalis, L. var. dubia and C. serotinus and shows good rice crop safety[1].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
