【摘要】 以灰葡萄孢菌为试验耙标,通过室内药剂驯化、紫外灯诱变,获得抗性突变体,并对抗性突变体的适合度进行测定,以评价新型杀菌剂啶菌恶唑的抗性风险。结果表明,经药剂驯化10代,抗性突变体的EC50值与敏感菌株无明显差异。在诱导14代后,EC50有所上升,但是抗性突变体的生长速率、产孢量等明显低于敏感菌株。因此,初步推断啶菌恶唑是一种抗性风险较低的杀菌剂。更多还原

【Abstract】 In order to evaluate the risk of SYP-Z048 resistance development, a strain of Botrytis cinerea was acclimatedto laboratory culture and initial levels of SYP-Z048 tolerance were determined , followed by UV mutation inductionand screening for resistance. Levels of resistance were found to be relatively low after ten generations but growth ratesand spores significantly lower than in the wild sensitive strains. Thus, risk of SYP-Z048 resistance development inBotrytis cinerea appears to be relatively low.更多还原
