Laboratory investigations on fungicides and biological agents to control three diseases of rubber and oil palm and their potential applications

Investigations of the effect of various fungicides and antagonistic species on the radial growth in culture of three pathogens of oil palm and rubber showed only phenylmercury acetate and cycloheximide to be effective against Corticium salmonicolor Berk. & Br. below 10 μg a.i./ml. Other promising fungicides were examined and seven were effective against Rigidoporus lignosus (Klotzsch) Imazeki and eight against Ganoderma sp. Trichoderma spp. were antagonistic to all the pathogens. The practical application of these results in the field are discussed. © 1983 Taylor and Francis Ltd.
