Argentine weed sensor to lift herbicide accuracy
Argentine researchers have developed a sensor for detecting the intensity of weed infestations. The device should allow a more precise application of herbicides on fallow land, the Argentine national agricultural technology institute, the INTA says. Its research centre based in Castellar developed the tool. The sensor would lead to a 30-70% cut in herbicide applications, depending on the target area’s degree of infestation. Some 38% of herbicide use in Argentina is on fallow land, costing $355 million a year, the institute says. It calculates that the use of the weed sensor would result in a likely annual saving of $178 million. The tool is inadequate for use on cultivated crops as it is incapable of distinguishing weeds there, the INTA cautions.
