Abstract |
The persistence and disappearance (washoff or dryfall) of methoxychlor from mature soybean (Glycine max) foliage was investigated in a small field plot study under natural rainfall conditions in 1977 and 1978. Residue analyses were conducted using whole plant samples. Methoxychlor washoff rate was 8 + or - 4% of the amount on plants (prior to rain) per centimeter of rainfall, regardless of time after application. Total seasonal washoff for 1978 accounted for 33.5% of the applied pesticide; however, 30.5% of the total loss was removed by washoff on the second day after application. Such algorithms are necessary for estimating runoff losses of insecticides to water bodies. |
