What is a significant disadvantage of ultra-low volume (ULV) formulations?

1. Low drift risk

2. Specialized equipment required

3. Easy to handle

4. Little residue

The correct answer is: Specialized equipment required

The selection of specialized equipment required for ultra-low volume (ULV) formulations is indeed a significant disadvantage because ULV applications involve delivering pesticides in very small droplet sizes. This necessitates the use of specific application devices that are capable of producing these fine droplet patterns effectively. As a result, applicators must invest in and maintain this specialized technology, which may not be accessible or economical for all operators. This requirement can also limit the flexibility and efficiency of pesticide application, as not every applicator has easy access to ULV equipment. Furthermore, improper use of non-specialized equipment can lead to ineffective pest control or increased risks to non-target organisms due to inappropriate application methods. In contrast, the other options do not accurately capture the challenges associated with ULV formulations: low drift risk suggests a containment of product rather than the need for specialized devices; easy handling may apply to certain formulations but does not address the complexity of ULV usage; and little residue refers to the management of pesticide residues rather than the application process itself.
