Pigweeds, grasses are shallow germinators which is primary targets of Zidua. 1/2" rain works good. Deep germinators are best controlled with post emerge. Cocklebur, sunflower would be common deep germinators. Hard to control with pre emerge program. 3-4" of rain will make Callisto disappear rather than make it active. Callisto is highly water soluable.
