Pests and diseases are important production constraints of snap beans in tropical and subtropical regions of the world. Among the most important conditions favoring their development are climate, planting susceptible varieties in monoculture over entire regions, staggered planting dates, and plan...

The paper starts with a description of parasites of small ruminants in the Philippines. It then discusses host-parasite relationships and worm control options; looks into worm control programs; and examines impact of helminths on production. It then discusses anthelmintic plants and biological co...
