The persistence of the methylcarbamate pesticide carbaryl was studied in four soils under flooded conditions. A substantial portion of the pesticide was recovered from all soils even after 15 days of its application, with the recovery ranging from 37% in an alluvial soil to 73% in an acid sulfate soil. The degradation of carbaryl was more rapid under flooded conditions than under nonflooded conditions. A bacterium, Pseudomonas cepacia, isolated from a flooded soil amended with a related methylcarbamate pesticide carbofuran, degraded carbaryl in a mineral medium supplemented with yeast extract.
在淹水条件下，对四种土壤中氨基甲酸甲酯类农药西维因的持久性进行了研究。即使在施用该农药15天后，所有土壤中仍能回收相当一部分农药，回收率从冲积土中的37%到酸性硫酸盐土中的73%不等。与非淹水条件相比，西维因在淹水条件下的降解更快。从添加了相关氨基甲酸甲酯类农药克百威的淹水土壤中分离出的洋葱伯克霍尔德菌，在添加酵母提取物的矿物培养基中能降解西维因。
