Improving Control of Summer Weeds
Useful article from the WA DPRID on weed control including information on how to determine of weeds are under stress, whether you need to add an additive to improve herbicide effectiveness and when is the right time to spray
Summer weeds can rob subsequent crops of soil nitrogen and stored soil water. They can also reduce crop emergence by causing physical and/or chemical interference at seeding time.
Achieving timely control of summer weeds can result in tangible benefits through increases in crop yield and/or quality and speed up the sowing operation.
However, the best time to treat these weeds may also coincide with hot temperatures, follow periods of severe moisture stress and require the inclusion of additives to the spray tank.
