Development of resistance inGloeosporium ampelophagum andColletotrichum capsici to fungicides

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Gloeosporium ampelophagum andColletotrichum capsici were trainedin vitro for development of resistance to different fungicides. In general, the resistance developed by both the fungi was of low order ever after 10–14 generations of training.G. ampelophagum developed two-fold resistance to fentin and wettable ceresan, four-fold resistance to zineb and copper sulphate and 200-fold resistance to ziram. The resistance developed to ziram did not persist throughout the training period.Colletotrichum capsici acquired two-fold resistance to zineb and copper sulphate and two and a half-fold resistance to mercuric chloride.
