The effect of moisture level on the persistence of mancozeb and propineb in sandy clay soil was studied over a period of 60 days. The soil moisture levels were maintained at 20, 50, 80% of the field capacity. The residues of mancozeb and propineb dissipated with half-life of 8.7–9.5 and 6.5–7.3 days, respectively. Although the dissipation rate increased with the increase in the moisture level of the soil, the effect was not much prominent.
