Improvement of Control Efficacy of Mancozeb Wettable Powder against Citrus Melanose by Mixing with Paraffin Oil
This study was carried out to determine the effect of mixing with paraffin oil on rainfastness of mancozeb on citrus fruits and assay the improvement of control effect of mancozeb against citrus melanose by mixing with paraffin oil. In artificial rainfall condition (7.2 mm/hr), the attached conten...

This study was carried out to determine the effect of mixing with paraffin oil on rainfastness of mancozeb
on citrus fruits and assay the improvement of control effect of mancozeb against citrus melanose by mixing
with paraffin oil. In artificial rainfall condition (7.2 mm/hr), the attached contents of mancozeb on detached
fruits were the most in treatment of mancozeb 0.2% + paraffin oil 0.1% as the contents was 7.43 μg/cm2 after
treatment of rainfall for 10 hr. In open field condition, the contents of attached mancozeb on fruits were significantly
more in treatment of mancozeb 0.2% + paraffin oil 0.1% or 0.25% than the other treatments 1,
15 and 25 days after treatment 2009 and 2010 seasons. The disease incidence was significantly lower in
treatment of mancozeb 0.2% + paraffin oil 0.1% or 0.25% than treatment of mancozeb 0.2% only 2009, 2010
and 2011 seasons. Based on this study, it was suggested that the control effect of mancozeb against citrus
melanose can be improved by mixing with paraffin oil. |
