Shielded application technology reduces herbicide runoff in furrow-irrigated sugarcane plantations
Scientists from CSIRO, Australia, trialled a new technique for applying herbicides to raised beds of furrow irrigated sugarcane by using a specially adapted shielded sprayer. The technique minimises the likelihood of herbicides such as diuron, atrazine, ametryn and hexazinone coming into contact with irrigation water. The conventional application of herbicides in furrow-irrigated sugarcane production is to broadcast spray across the whole field using boom sprayers. By using shielded sprayers, runoff of highly soluble herbicides showed a 90% reduction.
