The Problem Isn't You. It's How It Was Explained to You.

You're at the edge of a client's pond with a rake full of green growth, and the first question is simple: what group is this? Algae, floating, submersed or emergent.

The manual covers the four groups in page after page of paragraphs, one after the other. Read back to back, they blur together, and the group is what decides the rate line, the product and the timing.

Algae, floating, submersed, emergent: one pond, one question, four groups.

In this book it's one page: one pond, drawn with the four groups in their place. Algae in the water, floating plants on the surface, submersed plants below it, emergents along the shoreline. One question, four answers.

Same with hydrilla vs elodea vs egeria, acre-feet, the 2.7 rule, contact vs systemic herbicides and water-use restrictions: each one has its own page.

You see the group, you know which way to treat it, and you get on with the job without going back to the manual.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line after line
  • Acre-feet and ppm explained only in words
  • You walk into the exam second-guessing yourself
To determine the quantity of herbicide required for an in-water application, the applicator must first establish the surface area of the water body, expressed in acres, and its mean depth, derived from a series of soundings taken at regular intervals. The product of these two values yields the volume in acre-feet. Since one acre-foot of water weighs approximately 2.72 million pounds, a concentration of one part per million corresponds to approximately 2.7 pounds of active ingredient per acre-foot; this figure must then be multiplied by the target concentration and converted into a product quantity in accordance with the label.
FOR THIS
  • The pond drawn with its area and average depth
  • Acre-feet and the 2.7 rule in one box
  • You see it and you get it
Sun → algae and plants → zooplankton and insects → fish: plants are habitat and oxygen.

One Page, One Topic, All Clear

Think of it this way:

A client calls: the pond is choked with a submersed weed and you need to know how much product goes in. First you need the volume in acre-feet, and it has to be right.

In the book you open the acre-feet page and see the pond drawn with its surface area, its average depth and the multiplication between them: area × average depth, in the same order every time.

Floating and emergent weeds: per surface acre. Submersed weeds and algae: ppm in acre-feet.

Same with the four plant groups, hydrilla vs elodea vs egeria, the 2.7 rule, contact vs systemic herbicides and treating in sections: each one on its own page.

Aquatic Pest Control Illustrated is 9 parts and 64 topics, all drawn, and at the end you get the look-alikes and every pond formula on one page, three practice problems solved step by step and a before-you-treat checklist.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I already work on ponds and need the aquatic category on my license?

Yes. It's written for applicators who already do the field work, under supervision or adding the aquatic category to their license. It isn't a beginner's book: it covers surface-acre vs ppm rates, ppb, flowing water, sprayer calibration and treating in sections. It follows the content common to state aquatic category manuals, which are built on the EPA standards (40 CFR Part 171). Category numbers and some rules change from state to state, so check your own state's manual for its category number and any state-specific requirements.

Where does the content come from?

From the EPA applicator certification standards (40 CFR Part 171), the aquatic category study manuals used by state lead agencies and Cooperative Extension, FIFRA label language and the NPDES Pesticide General Permit.

Is it official material?

No. It's an independent illustrated study book. It isn't issued or endorsed by the EPA, any state agency or any manufacturer, and it doesn't give you a license, a certificate or continuing education credits: those come only from your state's exam and approved courses.

Does it replace the official manual or the required training?

No. It helps you study and review what's in them, with drawings. Every dose calculation shows each step with its units, so you can check it line by line, and it uses the standard conversions from Extension aquatic manuals (1 acre-foot = 43,560 cubic feet; 1 ppm in 1 acre-foot ≈ 2.7 lb). They are study exercises: in the field, your state's rules and the product label always come first. The label is the law.

Are the practice questions the ones on the exam?

No. They're written for this book, exam-style, with the answer explained. They are not official questions from any exam.

When and how do I get it?

The book and the 2 bonus books come as a PDF by email, to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment. No subscription.

Can I have it on paper?

Yes. The PDF is printable: print the whole book or just the pages you want to keep in the truck or the boat.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
