Which characteristic is true regarding dusts (D)?

DUSTS (D) are formulations that are applied in a dry form and consist of fine particles. One of the key characteristics of dusts is that they can pose severe inhalation hazards, particularly during the mixing and loading processes. This is due to the fact that dust can easily become airborne and be inhaled by the applicator if appropriate precautions are not taken. The fine particles can remain suspended in the air, increasing the risk of respiratory exposure, which is why it's crucial to handle these materials with care.

Understanding this characteristic is essential for ensuring safety in handling and using pesticides. This is particularly important for applicators and workers who may be near the areas where dust is being mixed or loaded, as adequate protective measures must be in place to minimize inhalation risks.

On the other hand, while dusts may not leave a visible residue like some liquid formulations, they can still be harmful through inhalation. They generally do require agitation prior to application to ensure uniform distribution of the active ingredient, and while they might present lower inhalation hazards during application compared to mixing/loading, the mixing and loading phase is where the most significant exposure risk occurs.
