Setting a Rate as a Concentration

An aquatic Target concentration rule states the rate the way the label does: so many parts per billion or parts per million of the water being treated. The treatment plan multiplies treated acres by average depth to get acre-feet, then sizes the jug from that.

How to attach shipped defaults, and what Ready to attach means, live in Dosing Rules and Application Rates. Why 90 ppb and 1 ppm are the shipped numbers lives in Why Aquatic Application Rates Are Set This Way.

Inventory is included on Crew and up. Concentration rules apply to aquatic accounts.

How to Enter a Concentration Rate

Open the product under Inventory and tick Application Rate. Everything below is the concentration path; Per acre (linear) keeps the multiplier, example acres, and depth anchors exactly as before.

1. 1

   Pick the rule type

   Rule type offers Per acre (linear) and Target concentration. On a new product whose name we recognise, the shipped rule is attached on its own and the form says the default rate follows the stock unit until you change the formula. When the formula is unticked on a recognised product, or an existing product has no rule, the form offers Use the default rate (…) with the shipped rule in words; clicking it fills every field below. An existing product that already carries a rule is left alone.

   A Flumigard, Clipper, or flumioxazin name ships two rules, so the form says This looks like Flumigard Herbicide, which ships more than one rule — pick the one your label states. and offers Use a shipped rule with Flumigard Herbicide · 12 oz per acre and Flumioxazin (submersed) · 200 ppb of active ingredient (label 200–400 ppb).

2. 2

   Enter the target

   Target takes the number, and the ppb | ppm toggle beside it says how the label reads it. Switching the toggle restates what you typed rather than reinterpreting it: 90 ppb becomes 0.09 ppm, and the stored rule is unchanged. Copper sulfate and dye labels read in ppm, fluridone and flumioxazin in ppb.

3. 3

   Say what the label counts

   Label states the target as is Active ingredient (Sonar, Clipper) or Product (copper sulfate crystals, dye). Active ingredient needs the product's strength, and the stock unit decides which field appears: Liquid — lb active per gal on a volume unit (Sonar A.S. is 4), Dry — % active on a weight unit (the Clipper and Flumigard granule is 51). A product stocked in plain oz shows both; fill the one the jug is, and when both are filled the dry one is used. A product label needs no strength; the rate follows from the weight of water alone.

4. 4

   Enter the band

   Label min, Label max, and Lake ceiling read in the toggle's unit; the lake ceiling is optional and only applies on Lake Treatment visits. Saving a target outside the band is refused, on the form and again on the server, with the same sentence: The target of 200 ppb is outside the label band of 45–90 ppb (lakes to 150). A minimum above the maximum is refused too. A lake ceiling above the label maximum widens the band: a target between the two, say 120 ppb on the shipped fluridone rule, saves, is applied as stated on a Lake Treatment visit, and is sized at 90 with the caution on a pond.

5. 5

   Check the rate

   The form shows the number the plan will use: Derived rate: 0.087 fl oz per ppb per acre-ft. (copper: 2.72 lb per ppm per acre-ft). It re-derives whenever the strength or the stock unit changes. For a label that states its rate by volume rather than by strength, such as dye, click Enter from label instead and type it into Rate from label (gal per ppm per acre-ft); Aquashade is 0.25. While a rate is typed the strength field is set aside; Use the derived rate (…) brings the strength back.

6. 6

   Read the preview and save

   Example acres and Example avg depth (ft) drive one line that reads the way the plan will: 0.5 ac × 4 ft = 2 acre-ft → 15.66 fl oz at 90 ppb. A blank example depth reads 4 ft (assumed), and a target the ceiling cut down ends (label ceiling).

   The server recomputes the derived rate from the strength you entered, never from the number the form showed, keeps a typed rate as typed, checks the target against the band again, and stores the rule. Attaching a default never rewrites a rule you built by hand.

Symptom-Specific Formulas work the same way: every row has its own Rule type and, for a concentration row, the same controls. + Add Symptom-Specific Formula starts the row from the default rule's type and copies its concentration fields.

Verify it worked

1. Open the product under Inventory. Application Rate is ticked, Rule type is Target concentration, and Derived rate matches the label.
2. Open SettingsTreatment Protocols. Under Application Rates, the product reads Has rule, with the target in words (for example 90 ppb of active ingredient).
3. On the next pond visit, the treatment plan line shows the water it sized for, such as 90 ppb over 8 acre-ft (2 ac × 4 ft).
