Abstract
Bean anthracnose, caused by the fungus Colletotrichum lindemuthianum, is a worldwide disease in susceptible var. grown in locations with cool to moderate temp. and with a high RH. It can appear anywhere in the plant. Losses can be up to 100 percent when severely infected seed is planted. For efficient disease control, the production of disease-free seed, crop rotations, utilization of adequate chemical…

Abstract
Many factors can severely affect beans during their growth cycle. Parasitic plants, such as Cuscuta epithymum and Cassytha filiformis, can reduce yields. Various environmental conditions including frost, extreme conditions of high or low MC, sudden changes in soil and air temp., and periods of intense sunlight and wind can damage bean seedlings or mature plants. Variations in soil properties and…

Abstract
One of the most important bean-production constraints in tropical and subtropical Africa is the wide range of insect pests, which attack every part of the bean plant (from roots to pods and seeds) causing heavy losses either in the field or in storage. Losses can be up to 100 percent depending on area, season, cv., planting date, and cultural practices. Ophiomyia phaseoli, which…
