The strategies module works out a maximum profit solution of weed control for a sequence of crops over a number of years. It uses the initial weed density and then tracks to likely effects of these weeds on the current crop and the amount of seed that is likely to be produced which will affect subsequent crops. It incorporates both chemical and non chemical methods of weed control. It is still being refined as better data becomes available but does provide some useful insights into the longer term effects of weed control programs.
