water floating technique (wFT) is a practical tool used by farmers in determining the presence of cyst
nematodes in potato fields.
water holding capacity (wHC) refers to the amount of water a soil can hold which is proportionately related
to the physical condition and organic matter content of the soil. Soils high in organic matter are darker
in color and have greater water holding capacities than do soils low in organic matter.
water management means any strategy or method that will lead to effective and efficient use of water in

whitefly is a small white insect pest belonging to the fly family, which congregate on the undersides of the
leaves where they suck juices and secrete honeydew. Severe infestation can cause plants to wilt.
white muscardine fungus (Beauveria bassiana [Balsamo] Vuillemin) or wmF is a naturally occurring
insect pathogen that is commonly collected in agricultural crops for pest control worldwide. During
development, fungus uses soft tissues and body fluids of host. The growth of WMF requires conditions
of prolonged high moisture for airborne and waterborne spores to germinate. When ready to produce
chalky-white spores, fungus grows out of host’s body.
