W. Dykes ; AMERICAN SOCIETY OF AGRICULTURAL ENGINEERS | St Joseph (USA) : ASAE - American Society of Agricultural Engineers | ASAE Paper n°80-1007 | 1980Resistance heating was identified as the primary principle of electrical weed control as a result of laboratory and field experiments. The concept of utilizing differential tolerance to achieve selectivity in weed control was explained. The desi[...]
