What time of day is best to spray herbicide?

Systemic herbicides work best when applied late morning, midday and in the afternoon in cool or cold climates. Plant growth slows down at dusk and speeds up again as the sun rises the following day. Heavy early morning dew can cause herbicides to run off, so it's best apply them after dew has evaporated.

Can you spray Roundup with dew on the grass?

Weeds tend to be happy in the morning, just before the dew on their leaves has evaporated under the morning sun, and this can be a good time to spray them. There is no conclusive evidence that dew either inhibits or enhances the effect of the glyphosate in Roundup.

Most of the time, 2,4-D breaks down in soil so that half of the original amount is gone in 1-14 days. This breakdown time is called the “half-life” of the pesticide. One form of 2,4-D, the butoxyethyl ester, had a much longer half-life in aquatic sediment of 186 days.
