Disease relevance of ethoprop

• Inoculation of a soil freshly treated with cadusafos or ethoprophos (10 mg l(-1)) with high inoculum densities (4.3 x 10(8) cells g(-1)) of Sphingomonas paucimobilis resulted in the rapid degradation of both nematicides [1].
• Pseudomonas putida epI was capable of degrading ethoprophos when only 60 cells ml(-1) were used as initial inoculum [2].

High impact information on ethoprop

• The hydrolytic half lives of ethoprophos in distilled, river, brackish and open sea water were 25, 133, 65 and 81 days, respectively [3].
• A 145-acre potato field adjacent to Dorris, California, was treated with ethoprop (Mocap) to control nematodes [4].
• PRZM, PELMO, PESTLA and LEACHP all showed similar mean leaching depth to each other, whereas VARLEACH predicted lower ethoprophos mobility and PLM and MACRO predicted greater mobility [5].
• Although all twelve chemical pesticides were effective in reducing the population of A fragariae in the soil 45 days after treatment (DAT), only diazinon 475 g liter-1 EC, trichlorfon 800 g kg-1 SP, ethoprophos 100 g kg-1 GR, oxamyl 100 g kg-1 GR and ZeroTol caused over 70% reduction in nematode population compared with the control [6].
• Ethoprop, with an acute oral LD50 near 5 mg/kg and an acute dermal LD50 of approximately 3 mg/kg, was the most toxic compound tested and could not be fully evaluated for its potential to cause OPIDN [7].
