Select your product, application type, and sprayer size. Get the exact amount of concentrate to measure — with step-by-step mixing instructions. All rates are based on published EPA-registered labels.
Pesticide labels give a rate like "0.5 fl oz per gallon." Here's what that actually means and how to scale it up for any tank size:
| EC | Emulsifiable Concentrate — liquid, mixes with water to form milky emulsion |
| SC / CS | Suspension Concentrate / Capsule Suspension — tiny particles suspended in liquid |
| WP | Wettable Powder — dry powder that mixes with water; often sold in pre-measured packets |
| WDG / WG | Water-Dispersible Granule — granules that dissolve when added to water |
| RTU | Ready to Use — pre-diluted, do not add water |
| REI | Re-Entry Interval — minimum time before people/pets can re-enter treated area |
| PHI | Pre-Harvest Interval — days between application and harvest (agricultural) |
All rates below are from published EPA-registered labels. Rates reflect general/perimeter applications unless noted. Always consult your specific product label — rates vary by site, pest, and formulation lot.
