Pesticide contamination can be long-term and have a significant impact on decomposition processes and nutrient cycling. Therefore, their degradation can be expensive and difficult.
The most commonly used fungi for helping in the degradation of such substances are white rot fungi, which, thanks to their extracellular ligninolytic enzymes like laccase and manganese peroxidase, are able to degrade high quantity of such components. Examples includes the insecticide endosulfan, imazalil, thiophanate methyl, ortho-phenylphenol, diphenylamine, chlorpyrifos in wastewater, and atrazine in clay-loamy soils.
