Which liquid pesticide formulation may approach 100 percent active ingredient?

• A. ULV
• B. EC
• C. WP
• D. SP

Answer: (A)

Ultra-Low Volume formulations are designed to be extremely concentrated, delivering very little liquid while providing a high amount of active ingredient. Because there’s barely any carrier solvent, the active ingredient can constitute nearly all of the product, often approaching 100 percent by weight. The other liquid types include solvents and carriers (emulsified in water or oil), so their active ingredient is only a fraction of the total formulation. Wettable powders and soluble powders are not liquids themselves and contain substantial inert material or require dissolution, so they do not approach pure active ingredient like ULV can. So ULV is the liquid formulation most likely to approach full strength of active ingredient.
