“…of diazin on and stored at 4°C for 19 months; the results were highly variable since there was a total loss of this insecticide in the extractives fortified with one p.p.m. and only 25 per cent loss in the sampies fortified with the higher concentration (GUNTHER 1969). However, chloroform extractives of broccoli, cabbage, and cauliflower fortified with one and two p.p.rn.…”

“…In one study, GUNTHER (1969) reported that methylene chloride extractives of oranges fortified with two levels of dimethoate and stored at 4°C for four months had insecticide losses ranging between one and 22 percent. However, in a later similar study, GUNTHER and WES'ILAKE (1972) reported no losses of dimethoate residues from citrus extractives solutions stored also at 4°C for four months.…”

Deposition and persistence of carbofuran in vegetation and grasshoppers of two prairie pastures were measured after single aerial applications at 134 g a.i per hectare in 1987 and 1988. Mean depositions on horizontal filter paper samplers were 43 1 and 64 9% of the nominal rate in the two applications Variability of deposits, measured as C V.s, were 76 4% and 86 9% Carbofuran residues in vegetation and grasshoppers were less variable than those in deposit samplers, with C V s of 40 6 and 70 6% in vegetation and 58 6 and 32 5% in grasshoppers for 1987 and 1988, respectively. Residues declined by 50% in 24 h both years from initial concentrations (3 h postspray) in vegetation of 13 3 and 10 8 μg/g Initial residues in grasshoppers averaged 2 2 μg/g in 1987 and 3.9 μg/g in 1988; the mean for both years was 2.5 μg/g Grasshoppers contained the same concentration of carbofuran 3 h after spraying, whether collected live or dead Maximum residues of 5 7 μg/g were found in grasshoppers from two of the 40 sites sampled in both years A model fitted to the data indicated that there may have been about a 24 to 44% loss of residues from vegetation, probably due to volatilization and other processes, before samples were collected at 3 h There was a decline in residues per grasshopper of 30% in 24 h both years, which was not evident when expressed as micrograms per gram because of desiccation of the dead insects The concentrations of carbofuran in the vegetation and grasshoppers were typical of aerial spraying, hence, they may be used as baseline values for estimating exposure of herbivores and msectivores to insecticide deposits from similar spray events by adjusting for rate of application Deposits measured on filter papers were positively related to concentrations in vegetation and grasshoppers Calculations of the potential effects on wildlife of ingesting sprayed grasshoppers, combined with other routes of exposure, indicated a relatively low hazard for herbivorous rodents but a relatively high hazard for insectivorous adult passerines and their young Monitoring passerines in a related field study did, however, not reveal any effects on survival within 3 d of spraying carbofuran.
