2,4-DP (Dichlorprop)

Applied in cereal grains, pastures, turf/ornamentals, and for brush control; it can move with runoff and breaks down over days to weeks in the environment [2][1].

Skin contact or breathing spray drift during/after applications; touching treated grass; eating residues on crops; drinking contaminated private well water near treated areas [1][3].

Short-term exposure can irritate eyes/skin and cause nausea, vomiting, and weakness; very high doses have caused muscle and nerve effects. Long-term high-dose animal studies show liver and kidney changes; regulators set limits to reduce risk [1][3][2].

Pesticide applicators/mixers, farm and lawn-care workers, children and pets on recently treated areas, and people living near treated fields or using shallow wells [1][3].

Follow label and posted reentry times; keep kids/pets off until dry; close windows and bring items indoors during spraying; remove shoes and wash hands after outdoor play; rinse/peel produce; private wells near treated land—consider testing and appropriate filtration; workers—use PPE and wash up after use [1][3][2].
