Pesticides with high adsorption are likely to move from the application site by dusts.

Explanation:
High adsorption means the pesticide sticks tightly to soil particles, so it doesn’t readily move with water or through the air. Because it’s bound to those particles, the most likely way it travels away from the application site is when soil becomes airborne as dust; wind can lift and transport the dust, carrying the pesticide with it. It won’t move much by leaching or runoff since it’s not easily dissolved or carried by water, and it isn’t prone to evaporating because it's bound to soil particles and often has low volatility. So dust transport is the best explanation for how highly adsorbed pesticides can move away from the site.
