Abstract
Inoculations of young plants of Hevea brasiliensis by Rigidoporus lignosus (Kl.) Imaz. and Phellinus noxius (Corner) G. H. Cunn. Inoculations of young Rubber plants by two root rotting fungi, Rigidoporuslignosus and Phellinus noxius were performed under greenhouse conditions. For each parasite, parameters such as method of inoculation and level of soil moisture, were investigate. The results are discussed in relation to the fungal biology.
