As we approach the intense post-emergent spray window for many crops, here are a few tips to consider to maximize herbicide performance:
1) Match the most effective herbicide for the most difficult weeds to control in the field
2) Use tank-mixes whenever possible
3) Spray when weeds are small and at early leaf stages for the most effective control
4) Use full-labelled rates to maximize control and reduce chances of weed escapes which can lead to weed resistance
5) Use the most effective adjuvants when one is recommended with your herbicide and/or when water quality is a concern e.g. hardness
6) Use the correct spray volume
7) Choose the correct nozzle
8) Reduce speed of travel to ensure better coverage and to reduce drift
9) Apply during good weather conditions
10) Apply herbicides from 8 am to 8 pm, herbicide efficacy is enhanced during daylight hours
11) Remember to do a post-spray follow-up to evaluate herbicide performance and address any touch-up spraying required.
