Herbicides on forest land: SILLER BROS. INC.
Every gallon and pound of herbicide reported on forestry use reports, year by year, totalled from the county agricultural commissioners’ own records. Amounts are of the product as sold, not of active ingredient, and gallons and pounds are kept apart because they cannot honestly be added.

How these totals are made
- Only published forestry applications, and only what use reports say was applied. Notices of intent are plans, not use, and are left out.
- The same record sent in several formats is counted once.
- A product with two active ingredients is counted once, under the mix, so the chemicals add up to the yearly total.
- Rodent baits are not herbicides and are not counted. Tank additives are totalled separately.
- Ounces are read as fluid or weight ounces from the product’s formulation; anything that still can’t be converted is shown as “+ amount unit” rather than dropped.
- Totals grow as more counties answer records requests, so a low number can mean a county has not sent its records yet.
