What liquid pesticide formulation may approach 100 percent active ingredient?

The formulation that may approach 100 percent active ingredient is ultra-low volume (ULV) pesticide. ULV formulations are designed to deliver a very small volume of liquid, which means that a high concentration of the active ingredient can be achieved within that limited volume. This allows for greater efficiency and effectiveness in application while reducing the amount of carrier or inert ingredients that typically dilute the active ingredient in other formulations.

In practical terms, using ULV formulations allows pest control applicators to target pests with a potent dose, which can be particularly effective in situations where achieving thorough coverage is critical, yet the total volume applied needs to be minimal. This characteristic makes ULV a preferred choice for certain applications, especially in aerial spraying or when applying pesticides in large open areas.

Other formulations, like emulsifiable concentrates, ready-to-use solutions, and suspensions, typically contain a significant portion of non-active ingredients, which means they do not reach the same concentration levels of active ingredients as ULV formulations do.
