Summary, etc.	An investigation was done for exploiting potential biocontrol agents <br/>for the management of anthracnose of black pepper. Survey conducted on the <br/>incidence of anthracnose disease in eleven different locations of the state <br/>during February - July 2000 revealed that Colletotrichum gloeosporioides was <br/>the most common pathogen associated with this disease. Distinct variability in <br/>morphological characters and pathogenicity was exhibited by the di"fferent <br/>isolates of the pathogen. The most virulent isolate was isolate C6 from <br/>Perinthalmanna. The pathogen survived for three months on infected leaves in <br/>the soil and upto five months on infected leaves under laboratory conditions. <br/>A study was conducted to isolate potential mycoparasites of <br/>C. gloeosporioides from the rhizosphere and phyllosphere of both healthy and <br/>diseased black pepper plants from the various locations surveyed. Among the <br/>fungi isolated, two isolates of Trichoderma harzianum Rifai (T I and T 2) and <br/>two isolates of Aspergillus niger van Tieghem (A, and A2) were found to be <br/>most effective in' inhibiting C. gloeosporioides in vitro. After mass <br/>multiplication, the selected fungal antagonists were formulated in talc, which <br/>was found to be the best carrier material for maintaining the viability of the <br/>antagonists. The shelf life of the talc based formulations were 150 days and <br/>180 days for the T. harzianum isolates and A. niger isolates respectively. The <br/>antagonistic fungi were tested separately under greenhouse conditions by a <br/>combination of two methods of application viz., soil application and foliar <br/>spray. Greenhouse studies indicated that all the four isolates were equally <br/> <br/>effective In suppressing the development of the disease in black pepper <br/>cuttings. Application of the talc based formulations of the four isolates in the <br/>soil @ 109 / kg soil followed by foliar spray with one per cent suspension of <br/>the talc based formulations twice at 15 days interval starting from 10 days <br/>after pathogen inoculation was very effective in controlling the disease under <br/>greenhouse conditions. In general, application of the fungal antagonists <br/>promoted the growth of black pepper cuttings. Isolate Al produced maximum <br/>shoot length, root length and fresh weight in the treated black pepper cuttings. <br/>The results of the study assigned dual roles as biocontrol agents and plant <br/>growth promoters for all the four fungal antagonists. <br/><br/>
