Effect of baygon (2-isopropoxyphenyl N-methylcarbamate) on some soil biological processes and its degradation by a Pseudomonas sp.

Summary Baygon (2-isopropoxyphenyl-N-methylcarbamate) inhibited nitrification for 4 weeks at 25 and for 16 weeks at 1250 ppm. Ammonification of peptone was stimulated by baygon. Oxidation of ammonium formed from peptone was not complete in 16 weeks at 1250 ppm. of baygon. Solubilization of tricalcium phosphate was not affected by baygon. CO₂ production from soil was depressed for 10 days. Glucose addition caused the higher depression of CO₂ production after a week. A Pseudomonas sp. degraded baygon to 2-isopropoxyphenol. re]19730507
