Evaluation on Resistance ofBotrytis cinerea Isolates from Vegetable Crops to Different Types of Fungicides
摘要
Abstract
For investigating the development situation ofBotrytis cinerea resistance to different types of fungicides,85 isolates obtained from vegetables in North China were tested for their sensitivity to benzimidazoles (carbendazim),dicarboximides(procymidone),N-phenylanilines(diethofencarb),anilinopyrimidines (pyrimethanil),amides (boscalid) and phenylpyrroles(fludioxonil). The results revealed thatBotrytis cinerea in North China have developed different levels of resistance to 6 different types of fungicides,and the resistances to common fungicides including pyrimethanil,boscalid and fludioxonil were spread quickly in managing the grey mold. At the same time,Botrytis cinerea had generated a high level of resistance to carbendazim,procymidone, diethofencarb and the total resistance frequency were 72.94%,51.76%,69.41%,respectively. The frequency of double resistance to carbendazim and diethofencarb was 51.76%,whereas triple-resistance to carbendazim, procymidone and diethofencarb was 34.12%. Moreover,high resistance level was also detected in the testedBotrytis cinereato pyrimethanil and boscalid,2 common fungicides for controlling gray mold,with resistant frequency 64.71% and 65.88%,respectively. Resistant frequency to the new fungicides fludioxonil was 36.47%. Forty multiple-resistance type were found in this research,and 32 types have not been reported yet. One strain that was sensitive to the tested 6 fungicides was reported,with frequency of 1.18%,while 5 strains resistant to the 6 fungicides were verified,with frequency of 5.88%. We suggest that long-term repeated use of a single fungicide should be avoided in controlling grey mold,and application of multiple agents should be recommended so as to prolong the service life of fungicide.关键词
