Promising entomopathogenic fungal strains and application methods were determined, for use against Cosmopolites sordidus and Anthonomus eugenii. Bacillus popilliae isolates with potential against Phyllophaga elenans and P. menetriesi were also selected. A similar selection was carried out for weed pathogens against Rottboellia cochinchinensis, finding promising native fungal isolates. A series of antagonistic micro-organisms and soil amendments were tested to induce systemic resistance, to control or to decrease severity of plant diseases caused by Geminivirus, Pseudomonas solanacearum, and Phytophtora infestans in tomato; Mycosphaerella fijiensis in banana and Rosellinia bunodes in coffee trees. In all cases promising results were obtained both in screenhouse and field conditions. Plant growth of coffee, tomato and Musa spp was improved when nematodes infested soils were treated with endomycorrizic fungi. List(s) this item appears in: picudo
