This dataset contains fraction intercepted photosynthetically active radiation (IPAR) and corresponding percent of girdling lesions at harvest (pclesions) for 43 fields. Phomopsis stem canker is a worldwide fungal disease of sunflower, which causes stem girdling lesions and a consequent reduction in yield. One wants to decide if the number of girdling lesions at harvest in the absence of early treatment will exceed 15 This data frame consist of a sample of fields with values for IPAR (ipar) and for the percent of girdling lesions at harvest (pclesions).
