Degradation of guanidated amine acetates

摘要

AbstractThe active ingredient of the fungicide ‘Panoctine’ is a standardised mixture of guanidated amine acetates (GTA). This mixture was degraded in German standard soils with half‐lives of 400–600 days. GTA dressed on to wheat seed at 0.75 g kg−had a half‐life of 20 days when seed was incubated in Petri dishes at 25°C and of 80 days on seed sown in pots of soil stored outside. These results demonstrate a substantial influence of the test system on the degradation times of guanidated am
