a program to evaluate agricultural applications of multispectral satellite imagery in the rio grande valley is described. the primary application studied was that of monitoring defoliated cotton (gossypium hirsutum l.) stalk destruction for pink bollworm (pectinophora gossypiella $left bracket$ saunders $right bracket$ ) control. satellite scenes acquired on july 17, october 2, and november 13, 1988, indicated that other useful agricultural management applications would be possible, including mapping of saline soil and cotton root rot occurrence. initial results indicate that 20-m resolution multispectral satellite imagery is sufficient for on-farm management decisions about individual fields. 4 refs
