This study explores how communication and its technical content shape farmers' response to advice delivered at plant clinics. Thirty-six farmers who visited a plant clinic in one of three countries (Malawi, Costa Rica and Nepal) were given at least one diagnosis of a plant health problem and up to...

Frosty pod rot (FPR), caused by Moniliophthora roreri, reduces yields of cocoa (Theobroma cacao) by over 80% within a few years of disease outbreak. Both biological and chemical control approaches are being developed to supplement cultural management. Our objectives were to optimize the agent(s),...

Biocontrol agents of numerous insect pests and fungal pathogens exist but virtually nothing is known about their interaction if used simultaneously. Our objective was to investigate the compatibility of the entomopathogens Beauveria bassiana, Metarhizium anisopliae and Paecilomyces fumosoroseus,...

Moniliasis (Moniliophthora roreri) is the most limiting factor of cocoa (Theobroma cacao) production in Talamanca, Costa Rica. Participatory evaluation of cultural and biological control in organic smallholdings was carried out. Weekly and fortnightly removal of diseased fruits and seven biological ...

Economic mass production is a crucial stage in the development of biocontrol agents. This paper compares different solid substrates with and without preceding liquid culture for efficacy and economics in the scaled-up production of the mycoparasitic biocontrol agent Clonostachys rosea. In a basic...

Beauveria bassiana conidia were formulated as a dustable powder (DP), as oil suspensions (OS) and as a novel hydrogenated rapeseed oil pellet. These formulations were assessed against Sitophilus zeamais to study their potential use in the control of stored grain pests. Conidial viability was...
