A sports-turf manager uses a site-specific action threshold of 8 grubs per square foot.

Using treated acres = field acres x band width / row spacing, what is the largest legal product amount for the next application?
Correct answer: D - 1.5 gallons

Two labeled herbicides provide equivalent control near a shallow well. Product X is highly water-soluble, weakly adsorbed, and persistent.
