The article cites a study which states that the variable-rate application of defoliants using remote sensing technology could save Mid-South cotton producers US dollar 4 to US dollar 6 per acre in chemical costs. Variable-rate prescriptions were based on remote sensing imagery and used a normalized vegetative difference index of the field. The study was part of an overall project for adapting precision agricultural techniques for Mid-South cotton production. The study compared yields, grades and costs of variable-rate applications to blanket applications made by air on large, farm fields. The applications were made in long strips of 8 acres to 15 acres each. According to the study, variable-rate application of plant growth regulator is going to have some added benefit.
