## Description

Study National Core concepts with 240 original questions, a synthetic label decision lab, calibration and mix tools, and date-stamped primary sources.

Build pesticide-applicator knowledge and practice the decisions that matter before an application.

Pesticide Applicator Field Lab includes:

- 240 original questions across 12 National Core study domains
- Original explanations and source keys for every question
- 50-question readiness checks with a clearly labeled internal 80% study target
- Weak-area repair and bookmarks
- Treated-area, product-rate, tank-coverage and unit-conversion tools
- A boom-sprayer calibration calculator using the 5,940 formula
- A clearly fictional label-decision lab for REI, PHI, wind, buffer, PPE, rate and retreatment practice
- Date-stamped links to EPA and current federal regulatory sources
- Private on-device progress and offline study after installation

The free download includes two questions in each domain, one readiness check, all calculation tools and verified source links. One non-consumable purchase unlocks the full question bank, unlimited readiness checks, weak-area repair, bookmarks and the complete synthetic label lab. There is no subscription.

This independent educational tool does not issue a pesticide credential, replace product labeling or provide state-specific legal advice. Certification and application requirements vary by state, territory, tribe and federal program. The real product label and current requirements always control. The fictional training label is visibly marked not for real application.

Questions and explanations are original and are not copied from restricted EPA or state exam item banks. The app is not affiliated with, endorsed by or approved by EPA or any certifying authority, and it does not guarantee exam success.

No account, advertising, tracking, analytics SDK or cloud profile is used.
