What is the best time of day to spray weeds?

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.

In this case, the target was weeds, so the boom needed to be 30 inches above the average weed height. Spraying 30 inches above the target will subject the spray to more drift.

How much psi do you need for a spray gun?

The working range is between 15 and 50 psi, with smaller patterns requiring lower pressure. No two sprayers are likely to agree on the same settings, so it’s a matter of personal feel. Some typical settings: 15 to 20 psi:Airbrushing, touch-up, shading, sunbursting, and thin finish materials.
