| Fate | Soil and groundwater: Hydramethylnon is of low persistence in the soil environment; soil half-lives of 7 to 28 days have been reported [11,154]. A representative value is estimated to be 10 days [11,154]. However, a soil half-life of 18 hours has been reported, with breakdown probably due to decomposition by light and the rapid foraging of ants [11,154]. Because hydramethylnon is only slightly soluble in water and is very strongly sorbed by soil organic matter and clay particles, it is not appreciably mobile in most soils [11,154]. These properties, along with its low persistence, make it unlikely to contaminate groundwater [11,154]. When Amdro, a granular bait formulation, was applied to an aged soil column under laboratory conditions, 72% of the applied material remained in the treated soil after 45 days [8]. Less than 0.2% was recovered in leachate. This evidence supports the conclusion that neither Amdro nor its metabolites leach [8]. Breakdown in water: The reported hydro |
| Plant Metabolism Residues |
Over a 90-day rotation interval, hydramethylnon did not accumulate in crop plants [154]. In another study, residues in grass 4 months after treatment were less than 0.01 ppm. Negligible residues were found in radishes, barley, and French beans planted 3 m |
