Which characteristic is false regarding microencapsulated pesticides?

Microencapsulated pesticides are formulated using a technology that encases the active ingredients within a protective coating. This method is specifically designed to control the release of the active substance over time. Consequently, the characteristic that they provide immediate release of active ingredients is false. In fact, microencapsulation serves to provide a delayed or sustained release, which enhances the effectiveness of the pesticide by allowing it to be available to control pests over an extended period rather than all at once.

The other characteristics are accurate representations of microencapsulation. They can prolong effectiveness by slowly releasing the pesticide, thus maintaining its activity over a longer duration. Additionally, because the active ingredients are contained within a capsule, there is a potential reduction in exposure risks to humans and non-target organisms, as the pesticide is less likely to volatilize or drift. This also aligns with the use of microencapsulated pesticides for sustained pest control, as the gradual release allows for a more controlled management strategy, leading to better pest suppression over time.
