Precise data on actual crop loss is best obtained by field trials in which the control is kept as free of disease as possible. To assess crop loss to pathogens, two important links are yield comparisons of healthy and infested crops and a survey of the distribution of the pathogens. Cotton loss data from 80 research plots evaluated over 16 yr in six Southern High Plains counties are presented. |
