Implications of the 2002 drought for weed management locations
Aims

To discuss the implications of the 2002 drought for weed management.

Key messages

The 2002 drought may have major implications for potential weed problems during the 2003 season, including management in fallows, pastures and crops. However, there is very little published information on the impact of drought on weed population dynamics. There is some information on the impact of weather (rainfall and temperature) on effectiveness of weed control methods. The 1982 and 1994 droughts provide some guidance on the consequences of a major drought on subsequent weed problems. The most likely impact of the drought on weeds is the incursion of new weed problems into districts via fodder, grain and seed.
