Dissipation and Residues of Myclobutanil in Tobacco and Soil Under Field Conditions

Bulletin of Environmental Contamination and Toxicology Aims and scope Submit manuscript


Field experiments were conducted in two different locations to determine the dissipation pattern and residue levels of myclobutanil in tobacco leaves and soil. Myclobutanil 12.5 % microemulsion (ME) formulation was sprayed once at 3.0 mL/ha, and the residues in green tobacco leaves dissipated to more than 50 % of the initial deposits 5 days after application and up to above 90 % after 21 days. The dissipation rate of myclobutanil in soil was lower than that in green tobacco leaves. The residues dissipated above 50 % of the initial deposits 7 days after treatment and dissipated about 90 % after 42 days. The calculated half-life values (T 1/2) were found to be 4.89–6.77 days in green tobacco leaves and 12.88–19.20 days in soil, respectively. The ultimate residues of myclobutanil in flue-cured tobacco leaves and soil were determined after the third and fourth applications at levels of 2.0 and 3.0 mL/ha. Myclobutanil residues in cured tobacco leaves 21 days after the last treatment ranged from 0.85 to 3.27 mg/kg. Meanwhile, the residues detected in soil reached below 0.045 mg/kg 21 days after the last treatment.
