Crop losses due to pathogens and other harmful <strong>org</strong>anisms<br />
can be substantial and may be prevented or reduced by various<br />
control options, e.g. host plant resistance, physical, biological,<br />
and chemical control. For the period 2002-04, the potential losses<br />
due to pathogens, i.e. fungi, chromista, bacteria and viruses in<br />
worldwide production <strong>of</strong> 11 crops (barley, cotton, maize, oilseed<br />
rape, peanut, potato, rice, soybean, sugar beet, tomato, and<br />
wheat) was estimated at 15.8 and 3.8% <strong>of</strong> attainable production,<br />
respectively, compared to 34% and 18% for weeds and animal<br />
pests. The role <strong>of</strong> pathogens in production varies with crop, geographic<br />
region, and the intensity <strong>of</strong> production. The efficacy <strong>of</strong><br />
disease control, i.e. the proportion <strong>of</strong> loss potential prevented by<br />
direct control methods varied from 71% in high-input crop production<br />
in north-west Europe to
