Planning a Weed Control Programme Timing The timetable needs to be flexible according to conditions rather than calendar. The first spray should not be done until weeds have emerged and are actively growing and this will vary from year to year according to the weather. The graph below left shows spray windows as late April to mid-May for Spring treatment, with a subsequent optional spray in summer, and a further spray in the period August to September. Monitoring the Results Inspection and evaluation is essential to assess the performance and check if you need follow-up treatments. Weeds sprayed with Roundup Pro Biactive do not show signs of dieback until 10 days have elapsed. It is important to be able to recognise early symptoms, so that treated weeds can be identified. Symptoms show first in Annual Meadow-grass, which takes on a yellow tinge a few days after spraying. Other grasses follow by turning first yellow, then reddish brown before they die.

Broad-leaved weeds will appear healthy at this time, however, if you look closely you will see the leaves will be turning white in the centre. Within a week the plant will be dead. Use this guide to monitor the progress and effect of the treatment. You should expect 95% kill of all weeds to occur with the 5-litre rate, approximately 10 - 21 days after treatment. Any seedlings that germinate after spraying will NOT be affected. Always read the label. Use pesticides safely. Roundup Biactive, Roundup Max, Roundup Ultra ST and Roundup Gold contain glyphosate. Monitor contains sulfosulfuron. Latitude contains silthiofam. Ramrod contains propachlor.
