Project Type: Appropriated

Start Date: Feb 11, 2003
End Date: Jul 09, 2007

Objective:
Develop approaches to solving production problems of tropical crops with primary interests in production schemes for cacao and other alternative crops. This includes: development of biocontrol of diseases, the study of ecology of interactions among beneficials, pathogens, and plants, the optimization of biological and chemical pest control methods, the assessment of the soil infertility and management practices, and evaluation of responses of crops to stresses and management practices. Enhance the efficacy of environmentally and economically sustainable pesticides and biological control agents used in the control of cocoa diseases by improving application technology and formulation. Conduct a research program of microbial ecology and the exploration and screening of novel mycogens with potential for competitive action against cocoa disease pathogens.

Approach:
Classical and molecular techniques will be used to study ecology and genetics of interactions and evaluate genetic diversity among beneficial and pathogenic microorganisms to understand their role in the disease environment. The response of pathogens, biocontrol agents and host plants to biotic and abiotic stress will be dissected. Methods will be developed to screen biocontrol agents, fungicides, and formulation additives for the abilities to enhance control of diseases of tropical crops. Research will be carried out to evaluate the influence of abiotic stress on production and plant health of alternate crops. In collaboration with other research organizations of tropical and north America and Caribbean countries, carry out field studies to assess the impact of integrated pest management strategies, soil fertility, and crop management on productivity and health of high value alternate crops in order to optimize production potentials, tolerance to abiotic stresses, ecological adaptability, and disease control strategies to ensure sustainability.
