Conservation agriculture (CA) in Australia had its beginnings in the early 1970s with the release by ICI of Spray.Seed®, comprising paraquat and diquat (Pratley and Rowell 1987). However, it was not until 1978 with the release of diclofop (Hoegrass®) for post-emergent ryegrass and wild oat control and then the safer, more effective glyphosate (Roundup®) in 1980 by Monsanto for seedbed vegetation control that the tools were in place for adoption of direct drilling (DD) of crops. Adoption of DD was fastest in Western Australia (WA) with its large areas of sandy soils suited to DD and its larger farms and crop areas that benefited from more timely sowing.
