Cotton Whitefly (Bemisia Tabaci Genn.) - A Review*
Indian economy is primarily an agrarian economy. Agricultural production depends on various factors which either enhance output or limit the production. Any set back in these factors severely affects the output or yield. Of the total estimated losses caused in production by pests (insects, affects diseases and weeds) in the world, weeds alone are responsible for one third of it. Presence of weeds in general reduces crop yields by 31.5% (22. 7% in winter season and 36.5% in summer and kharif season). But as the farmers adopt some kind of weeding practices on their fields, a conservative estimate of 10% loss in crop yields may be taken as more realistic.
