seasonal timing was studies with 1:3,000 scale photography in 1976 (figs 3 and 4).
In the 3-week interval between Figure 3 and Figure 4, over 15% more of the cotton Crop in the field was affected with the disease.
timing photographic acquisition obviously must be as close as possible to the end of the cotton-growing season before harvest to determine maximum extent of disease.seasonal timing was studies with 1:3,000 scale photography in 1976 (figs 3 and 4).
