Which broadcasting method must specify crop species on the label?

The broadcasting method that must specify crop species on the label is the low-volume spray. This method involves the application of pesticides in smaller quantities, which can be particularly sensitive to specific crop types. When using a low-volume spray, the potential for non-target effects increases, and it is essential to provide clear guidelines on which crop species can safely receive the treatment without experiencing adverse effects.

Knowing the specific crop species helps ensure that the pesticide is effective and minimizes risks to other plants, local ecosystems, and beneficial organisms. This level of specificity is crucial for maintaining compliance with safety regulations and achieving desired pest control outcomes while safeguarding crop health.

In contrast, the other methods may not require specifying crop species in the same detailed manner due to differing application techniques or volumes that might reduce the likelihood of misapplication.
