Ideal time for spraying grass weeds
The best weather for spraying grass seeds this spray season need to be warm, not windy, not cold, not wet, with no rain forecast for the next 12 hours.
Spray the weeds after a deal of rain when there is growth in the weeds as well as in the grass.
The best thing to do is spray a dry leaf. Sometimes if you have a heavy dew, it doesn’t matter if the grass is wet, the important thing is that the weeds are sitting up and they are reasonably dry. Most products are rain fast within two hours of application.
Apart from avoiding windy conditions when spraying.
Right time to spray
Size of weeds is important. The spraying won’t be as effective if the weed is not sprayed at the ideal size.
Reseeding weed control
Spraying reseeds
Weeds in new reseeds are best controlled when the grass is at the 2-3 leaf stage
- Docks and chickweed are the two most critical weeds to control in reseeds.
- High populations of other weeds such as fat hen, charlock, redshank, mayweed can cause problems.
- It is essential to control docks and chickweed at the seedling stage. This is achieved by applying a herbicide before the first grazing.
- To achieve the best lifetime control of docks in a sward, eradicating the dock at seedling stage in a reseed is the best opportunity
- Herbicide choice for dock control will depend on the presence of white clover in the reseed
- Chickweed are a problem particularly where regular grazing is not expected to take place (silage fields), therefore herbicide choice is important.
- You should consult your local advisor for correct herbicide choice. Our team would be delighted to help!
- Remember to keep the prescribed cross-compliance records and follow the instructions on the product label.
- Have a look at this video from Teagasc for best practices when using pesticides this spray season.
