The environmental behavior of five organophospate insecticides in Florida citrus are reported. Parathion disappearance rate from fruit, leaf, and soil surfaces was the same. Potential worker exposure to parathion was leaf surface, soil surface, fruit surface, and a minor component in air. Disappearance of parathion surface residues was accurately represented with a first-order solar radiation, rainfall, temperature, and dew model. Dialifor, malathion, oxydemetonmethyl, and dioxathion fruit and leaf surface residues exhibited different disappearance rates. The disappearance rate, however, was the same on fruit and leaf surfaces for individual compounds. Based on rates of disappearance uner different environmental conditions, environmental sensitivity was oxydemetonmethyl malathion dioxathion dialifor. These data suggest that fruit data could be eliminated from worker safety reentry registration requirements for organophosphate insecticides. Two surface residue techniques were compared. Vacuum and dislodgeable residue techniques differed in the amount of particulate matter and pesticide residue recovered. Vacuum, dislodgeable and air particulate numbers and sizes were relatively comparable. The dislodgeable residue technique for worker reentry data appeared superior to the vacuum technique.
