- Read the label in full before use
- Target weeds at the right size – young and actively growing is best. If you have topped the weeds first then wait 2-3 weeks for sufficient weed regrowth before spraying
- Wear suitable protective clothing when spraying – gloves, coveralls and rubber boots
- Spray must be aimed away from the water courses
- Keep other people and pets out of treated areas for at least 2 hours until spray has dried on leaf
- When spraying is finished, clean out the tank, spray lines and nozzle, making sure the washings go on an untreated area. If the container is empty, rinse thoroughly 3 times with clean water and dispose of the rinsings on an untreated area
- Re-seed bare patches of soil where weeds have previously been
- Ragwort label guidance - where ragwort is present users should consult the Code of Practice on How to Prevent the Spread of Ragwort. Ragwort plants sprayed with this herbicide are more palatable and contain higher levels of toxins. Animals should be excluded from treated areas until any ragwort has completely recovered or died and there is no visible sign of the dead weed. Do not include treated ragwort in hay or silage crops.
Follow up treatments are sometimes needed:
- Not all weeds are at their ideal treatment size at the same time
- The visible weed above ground can be small compared with often extensive root systems below ground
- Large numbers of weeds can shade each other
- Grassland with large weed populations often holds higher levels of weed seed in the soil
- Removal of weeds can leave bare patches of ground ideal for further germination of weed seeds.
