- Executive summary:
A study has been carried out to determine the rate of degradation of MCPP-P 2-EHE in sandy loam soil under aerobic conditions at 5 °C for 56 days. The compound was applied to the soil as a commercial formulation ( MYLONE POWER Gel ) also containing ioxynil octanoate at the maximum recommended application rate. The moisture content of the soil was maintained at 75 % of moisture holding capacity at 1/3 bar.
The half-life of MCPP-P 2-EHE was calculated as 8.3 days and the major degradation product was MCPP-P acid.
