|Title:||In vitro antagonism of Phytophthora cinnamomi and P. citricola by Trichoderma species and Gliocladium virens|
|Citation:||Journal of Phytopathology, 1995; 143(8):471-477|
|Abstract:||Three fungi, isolated from soil from which Phytophthora was not obtained, were evaluated for antagonism of Phytophthora spp. shown to cause root rot of chestnut in South Australia. Trichoderma hamatum and T. pseudokoningii appeared to inhibit P. cinnamomi by mycoparasitism. with evidence of parallel growth and coiling, and both Trichoderma spp. and Gliocladium virens grew over P. cinnamomi in vitro, preventing further growth of this pathogen. Antibiotics produced by young T. hamatum cultures and G. virens in culture filtrate experiments inhibited growth of P. cinnamomi and P. citricola. with filtrate from 4-day-old cultures of G. virens showing the greatest potential for biocontrol. All three antagonists prevented P. cinnamomi and P. citricola from causing infection symptoms on micropropagated shoots of chestnut cvs Goldsworthy and Buffalo Queen in an in vitro excised shoot bioassay for biocontrol.|
