concept of optical (remote) sensing as a method to improve and automate phytotoxicity assessments of ornamental crops. Assessment of phytotoxicity in ornamental plants is typically based on visual inspection of leaves, shoots, or flowers at different
on soil temperatures. Through visual inspection of the turf canopy on multiple rating dates, the differences in canopy temperatures did not stimulate earlier green-up of colorant-treated vs. untreated zoysiagrass. Table 4. Effect of colorant on canopy
no differences in spring green-up of colorant-treated vs. untreated ‘Chisholm’ zoysiagrass at 2.5-inch mowing height. In our current study, through visual inspection at multiple rating dates, green leaves were observed emerging from colorant
inspection, the overall visual appearance of boxed grapes was rated according to the following scale: 1 = excellent, 2 = acceptable, or 3 = commercially unacceptable ( Crisosto et al., 2002 ). The data were subjected to a one-way analysis of variance using
9813-6N; Hanna Instruments, Woonsocket, RI). Greenhouse pests were monitored with sticky cards and plant inspections ( Gill and Sanderson, 1998 ; Powell and Lindquist, 1997 ). Yellow sticky cards were placed among the poinsettias at canopy height and

large degree. We developed a classification based on visual inspection of the data on percent reduction in DW at the 4.0-dS·m −1 vs. 14.2-dS·m −1 treatments and this correlates to four clusters we noted from Table 1 . Photographs at harvest taken from
