TI  - The enhanced biodegradation of fenamiphos in soils from previously treated sites 
      and the effect of soil fumigants.
PG  - 2099-107
AB  - The application of fenamiphos either alone or in combination with soil fumigants 
      is a common practice in greenhouses and potato-cultivation areas in Greece. 
      However, repeated applications of fenamiphos in the same field for a number of 
      years can lead to the development of enhanced biodegradation of the nematicide. 
      Studies in previously treated greenhouse sites and potato field sites in Greece 
      were employed in order to investigate the development of enhanced biodegradation 
      of fenamiphos and the respective effect of soil fumigants on the development of 
      the phenomenon. Enhanced biodegradation of fenamiphos in a soil from a previously 
      treated greenhouse site from the area of Aggelohori in Northern Greece was 
      observed using both incubation and bioassay studies with nematodes. Fumigation of 
      the enhanced soil with methyl bromide (MeBr) only temporarily inhibited 
      degradation of fenamiphos unlike metham sodium (MS) whose application 
      significantly reduced microbial degradation of fenamiphos. Similarly, enhanced 
      biodegradation of fenamiphos was evident in soil from potato fields that had a 
      history of previous exposure to fenamiphos. The slow rates of fenamiphos 
      degradation observed in soils from the previously treated sites after 
      sterilization with broad-spectrum antibiotics and also in soils from previously 
      untreated sites suggested that soil microorganisms were responsible for its rapid 
      degradation. The inhibition of enhanced biodegradation of fenamiphos in soil from 
      the previously treated greenhouse site caused by the antibiotic penicillin 
      probably indicates that Gram+ or other bacteria sensitive to penicillin are 
      responsible for the rapid degradation of fenamiphos in this soil. No 
      cross-adaptation was observed between fenamiphos and other nematicides registered 
      in Greece for the control of root-knot and potato cyst nematodes, including 
      cadusafos, ethoprophos, and oxamyl. According to our results, applications of MS 
      followed by fenamiphos or in rotation with other registered nematicides are the 
      most promising means for minimizing the risk of development of enhanced 
      biodegradation of fenamiphos in soils.
