Abstract

Mycofungicides have been formulated as biological products from Trichoderma T. harzianum PCOI and T. hamatum PC02 and Chaetomium C. cupreum CCI-IO and C globosum CGI-12 in the form of pellets. These were applied in the infested field-soil with Phytophthora parasitica integrated other cultural control measures could significantly reduce the pathogen inoculum and incidence of root and stem rot of Sweet orange Citrus reticulata Blanco when compared with the non-treated one. Antibiotic substances like Chaetoglobosin C and Trichotoxin A50 were proved for control mechanism implies antibiosis. The mycofungicide treatments were significantly higher in growth parameters and yield than the non treated one. Acute toxicity tests for Chaetomium and Trichoderma were proved for biological safety which the spores of Chaetomium and/or Trichoderma showed no apparent signs of acute toxicity in experimental mice.
