Each card covers one product on one crop. The big number is the extra yield per acre it produced against an untreated strip. Wins and losses both count. Open a card to see the trials behind it.
One card per trial. Without it is the untreated strip. With it is the treated strip. Same field, same season.
APSA-80 goes into the tank with a spray. The comparison is that same spray on its own. No untreated field appears in these numbers. Say it that way to a grower.

Irrigation Research Foundation trials, 1997 to 2024. Every figure in here comes off a sheet you can hand the grower.
Counted across every result with an untreated strip to compare against. Tank-mix results answer a different question and are counted on their own tab.
Product sheets from the manufacturer. The yield figures here are the company's own averages across its own trials. They are not the trial results in the other tabs, which all trace to a sheet you can hand over.
