Bentazone
Bentazone is a selective post-emergence herbicide and a Photosystem II inhibitor targeting the quinone B binding site, with activity against broadleaf weeds. Bentazone interferes with photosynthetic electron transport, blocks sunlight-dependent energy production, and acts as a phytotoxin to induce leaf damage, growth inhibition, lipid peroxidation, and reduced chlorophyll content.

生物活性
Bentazone (0-1.0 mg/L; 2-6 days) induces dose- and time-dependent increases in antioxidant (SOD, POD, root CAT) and detoxification (GST, GT, CYP450) enzyme activities in three-leaf stage japonica rice seedlings, with peak induction at 0.8 mg/L for 6 days[3].
Bentazone (0.8 mg/L; 6 days) alters global gene expression in three-leaf stage japonica rice seedlings, with more DEGs in roots than shoots, and upregulates genes involved in oxidative stress response, xenobiotic metabolism, and detoxification pathways[3].
Bentazone - tolerant and bentazone-sensitive soybean genotypes translocate 7-13% of absorbed foliar-applied bentazone from the treated leaf, with slow acropetal movement observed in soybeans[1].
Bentazone (0-1.0 mg/L; 2-6 days) impairs growth, membrane integrity, chlorophyll synthesis, and photosynthetic function in three-leaf stage japonica rice seedlings in a concentration- and time-dependent manner, with the strongest inhibitory effects observed at 1.0 mg/L for 6 days[3].
Bentazone (0-1.0 mg/L; 2-6 days) accumulates in three-leaf stage japonica rice seedlings in a concentration- and time-dependent manner, with higher accumulation in roots than shoots, limited translocation to shoots, and decreasing bioconcentration at higher exposure concentrations[3].
Bentazone (0.8 mg/L; 6 days) is metabolized in three-leaf stage japonica rice seedlings via phase I reactions (hydroxylation, hydrolysis, demethylation) and phase II reactions (acetylation, glycosylation, amino acid conjugation), producing seven distinct metabolites and fourteen distinct conjugates[3].
