All spraying should be done when the weeds are small before flowering - early in the morning or late in the arvo - no wind. It is a waste of spray if the weeds are not in a growing stage - as in, if it has been dry for awhile. Plants need to be growing to be able to move the chemicals through the plant. Use some dishwashing liquid in the spray - helps to stick better to plant leaves. If in a lawn mow regularly before it seeds and mow lower than normal to gather more seeds up if seeded already. Use Kamba M or a Bindi and clover weedicide. Or pull it out by hand after rain or watering. Have to keep at it to get on top. "The trick to stopping bindii from spreading is to spray them in winter as soon as you see them, before the prickles develop, and continue to repeat spray every 3 weeks until they are gone. Repeat spray is important as this will control weeds that have germinated after prior spraying."

Look at deep mulch no dig for at least a year. Plant mature seedlings into mulch. All weed seeds should die. Much will improve your soil. Thick layer of newspapers is critical.your goal is to eliminate light.
