WHAT’S A FORMULATION? How the pesticide is packaged. One pesticide = many forms. COMMON EXAMPLE LIQUID POWDERED - DRY BATH GEL

COMMONLY USE DRY FORMULATIONS WP – Wettable powder WSB or WSP – Water Dispersable Bag or Water Soluble Packet P or G – Pellets or Granule

Wettable Powders (WP) Finely ground dry material like talc and clay are the “carriers” Mixed with water - the i.e. is released into the solution Examples: Sevin 50 W insecticide Kerb 50 W herbicide Sniper 50 W insecticide

ADVANTAGES Easy to store & transport. Smaller packaging. Won’t freeze. Lower toxicity to plants than liquid formulations. Why? WETTABLE POWDERS (WP) The inert ingredients, clay or talc, are generally harmless to plants DISADVANTAGES  Inhalation hazard when pouring and mixing. It’s dry!  Needs vigorous & constant agitation in the spray tank.  Abrasive to many pumps and nozzles.

WATER SOLUBLE PACKETS OR BAGS Examples: Ammo WSP insecticide Thiodan WSB insecticide Some 2,4-D products Pre-weighted amounts of dry active formulation. Usually pellets Packaged in water-soluble plastic bags that dissolve in water.

WATER SOLUBLE PACKETS OR BAGS ADVANTAGES Reduce handling hazards associated with highly toxic pesticides. Plastic-like covering of bag acts as a barrier. DISADVANTAGES  Packets dissolve when exposed to water  Bags or packets are usually premixed at a specific rate.

GRANULES (G) OR PELLETS (P) Examples Spike 20 P Counter 15G Phostoxin (a fumigant in pellet or tablet form) Most often used for soil applications. Active ingredient (a.i.) is absorbed into large, coarse particles such as clay pellets or granules.

GRANULES (G) OR PELLETS (P) ADVANTAGES Ready to Use (RTU); no mixing In most cases, don’t need to mix with water first. DISADVANTAGES  May need to be incorporated into the soil.  Easy to over apply

Store pesticides in a locked and posted facility to keep out children or other untrained people. Lock all entrances to the storage area. Hang signs stating: "Danger — Pesticides, Keep Out!!"

Keep your storage area neat and clean!

Store pesticides only in the original container with the label plainly visible. Never store pesticides in anything used as a food, feed or drink containers, even for a short time. +=

Damaged containers? Transfer its contents to a container that held the same product. Contact the manufacturer and ask for an empty container. Attach a new label ASAP. Unlabeled pesticides are worthless and dangerous. Contact your local Montana Department of Agriculture Field Office for proper ways to use and dispose of surplus or questionable pesticides. All labels should be intact!

Keep clean water and soap close to, BUT NOT IN, the storage area. Note the disposable towels! A shovel, dustpan, broom, and proper type of fire extinguisher are other essential items.
