Methods were developed and evaluated that utilize state of the art weed-sensing technology in row-crop production systems. Spectral differences in green living plants and bare soil allowed 'real-time' weed detection, with intermittent spraying of herbicide only where weeds were present. Sensor units were mounted in 0.7-m-wide hooded sprayers providing sensors with an unobstructed View of the area between soybean rows. Single hood and commercial-size eight-row system were Evaluated, and savings in glyphosate spray solution applied using sensors ranged form 63 to 85/100, Compared to conventional hooded spray systems with continuous application.
