Vegetable crop management with remote sensingRepetitive aerial photography with color infrared (ACIR) and black-and-white infrared (B and WIR) films was taken of potato and tomato fields in southwest Florida during the spring season of 1975. Color differences observed in the photographs revealed different levels of soil moisture in the fields, improper ditch arrangements, poor stands of plants, and areas where late blight (Phytophthora infestans) (Mont.)d.By and early blight (Alternaria solani) (Ell. and Mart.) Jones and Grout. were defoliating potato plants. Photographs of fields before planting also indicated areas where excessive rock formations existed which would make field preparation costly. Preplanting photographs also pinpointed areas with different water table levels.
