What type of pesticide formulation allows for better adhesion on hard surfaces?

Microencapsulates are a pesticide formulation designed to improve adhesion on hard surfaces. This formulation involves encapsulating pesticide particles within a polymer or coating, which allows for a controlled release and better sticking properties when applied. The encapsulation increases the residence time of the pesticide on the surface it is applied to, which can enhance effectiveness and reduce the likelihood of runoff or loss due to environmental factors. This characteristic is particularly beneficial when targeting pests on hard, smooth surfaces, where other formulations may struggle to adhere effectively.

In contrast, dusts are generally less effective on hard surfaces due to their lightweight and powdery nature, making them susceptible to dispersal by wind or water. Wettable powders, while designed to be mixed with water for application, might not adhere as well to non-porous surfaces due to their reliance on liquid to create a suspension. Emulsions, which are mixtures of oil and water, can provide good coverage but may not possess the same level of adherence as microencapsulates when it comes to challenging surfaces.
