A season study (December 2008 to march 2009) was undertaken with potato crop and was found that propineb residue degraded faster in potato under field condition when applied at 1400 and 2800 g a.i ha-1. However, the propineb was noticed in soil on the day of propineb spray. Degradation was faster at lower dose of than higher dose of application with the half-life values of 2.3 and 2.5 days. The safe waiting period of 3.3 and 4.3 days was recommended for potato when applied at 1400 and 2800 g a.i ha-1 of propineb.

Abstract


A season study (December 2008 to march 2009) was undertaken with potato crop and was found that propineb residue degraded faster in potato under field condition when applied at 1400 and 2800 g a.i ha-1. However, the propineb was noticed in soil on the day of propineb spray. Degradation was faster at lower dose of than higher dose of application with the half-life values of 2.3 and 2.5 days. The safe waiting period of 3.3 and 4.3 days was recommended for potato when applied at 1400 and 2800 g a.i ha-1 of propineb.
