浓度测定

Preliminary bioassays indicated that many title compounds exhibited excellent fungicidal, or insecticidal and acaricidal activities. The strobilurin derivatives containing substituted pyrimide ring have lower biological activity than the strobilurin derivatives containing substituted pyrazole ring which exhibited good fungicidal activity against RB (0.92 mg/L), TLB (0.3 mg/L), CDM (12.5 mg/L) and WPM (1.56 mg/L).

初步生物活性测定结果表明，新型Strobilurin类化合物中多个化合物具有较好的杀菌或杀虫杀螨活性，其中吡唑类化合物要明显优于嘧啶类化合物，吡唑类化合物在低浓度下对水稻稻瘟病菌(0.92 mg/L)、番茄晚疫病菌(0.3 mg/L)、黄瓜霜霉病(12.5 mg/L)和小麦白粉病(1.56 mg/L)仍具有很好的杀菌活性。

Starting from the solubility of disperse dyes, the solubility, up-taking rate, migrating rate of dis_perse Yellow M-4G, Red 3B and Blue 2BLN at different concentration of Leveling Agent GS were tested by poly_mer thin-film bag method, thus demonstrating the hyperchromic effect and achromic effect of leveling agent during dyeing with disperse dyes.
