摘要进行259个灰霉病菌(Botrytis cinerea)菌株对多菌灵(carbendazim)、腐霉利(procymidone)和乙霉威(diethofencarb)的抗性检测,结果分为6种抗性类型:单抗多菌灵的类型(B~RN~SD~S)占36.3％,单抗乙霉威的类型(B~SN~RD~S)占24.7％,抗多菌灵和腐霉利的类型(B~RN~SD~R)占20.1％,抗多菌灵和乙霉威的类型(B~RN~RD~S)占6.9％,抗腐霉利和乙霉威的类型(B~SN~RD~R)占5.8％,同时抗3种药剂的类型(B~RN~RD~R)占6.2％。各地双抗或多抗菌株出现的频率分别为田阳73.9％,田东61.9％,武鸣30.1％,南宁8.7％,柳州2.6％。大多数多菌灵抗性菌株的抗性水平很高(EC_(50)>1000 mg·L~(-1)),大多数腐霉利抗性菌株的抗性水平较低(EC_(50)<10 mg·L~(-1)),而乙霉威抗性菌株中,双抗或多抗菌株的抗性水平较低(EC_(50)<5 mg·L~(-1));单抗菌株的抗性水平较高(25.1884 mg·L~(-1)<EC_(50)<119.9776 mg·...

Abstract：Multiple fungicide resistance of 259 Botrytis cinerea isolates collected from five sites in Gaungxi was detected to carbendazim ( B ) , procymidone ( D) and diethofencarb ( N). Resistance can be classified into six types according to being resistant (R) or sensitive (S). Among these BHNSDS type was 36. 3% ,the following were BSNRDS 24.7 % , BRNSDR20.1 %,BRNRDS6.9 % ,BSNRDR 5. 8% ,and BRNRDR was 6. 2%. The frequency of the isolates with multiple fungicide-resistance was 73.9 % in Hanyang,61.9 % in Tiandong,3...
