“…Initial residue levels found in the two matrices generally correlated with the deposit density at ground level ( Ruhr et al (1974). However, our findings differ from those of Johnson and Stansbury (1965), who reported DT50 values of 8 to 9 d. Detectable levels of carbaryl were found in soil up to 9 d postspray whereas in litter, it persisted to measurable levels (0.06 ppm) beyond the 10 d sampling period. The extended persistence of carbamate insecticide In litter was observed for aminocarb (Sundaram and Szeto, 1984).…”

An oil-based formulation of carbaryl (1-naphthyl N-methylcarbamate) (Sevin-2-Oil) was applied twice by a fixed-wing aircraft at a dosage rate of 280 g of A.I./ha/application to a coniferous forest near Allardville, New Brunswick. The highest concentrations of the chemical in fir foliage, litter and forest soil 1 h after application were respectively 4.20, 1.21 and 0.59 ppm (fresh weight).The residues dissipated rapidly and the DT50 values

“…Perhaps, the pulse of mois-ture reduced the efficacy of Sevin. Moreover, the product's efficacy might be reduced inside BTPD burrows characterized by high humidity (Wilcomb 1954); further, carbaryl exhibits a half-life of only *40 days in soil ( Johnson andStansbury 1965, Laveglia andDahm 1977).…”

Plague, a flea-borne disease, hampers efforts to restore populations of black-footed ferrets (Mustela nigripes), which occupy colonies of prairie dogs (Cynomys spp.) in North America. Plague is managed by infusing prairie dog burrows with DeltaDust Ò 0.05% deltamethrin, a pulicide that kills fleas. Experiments are needed to identify pulicides that can be used in rotation with DeltaDust for integrated plague management. In South Dakota, USA, we tested the efficacy of four pulicide dusts when applied at a rate of 8 g per burrow on colonies of black-tailed prairie dogs (Cynomys ludovicianus): Sevin Ò 5% carbaryl; Dusta-cide Ò 6% malathion; Alpine Ò 0.25% dinotefuran with 95% diatomaceous earth; and Tri-Die Ò 1% pyrethrum with 40% amorphous silica and 10% piperonyl butoxide. We also tested systemic 0.005% fipronil, which was distributed as ½ cup of laced grain per burrow. We sampled prairie dogs on 3294 occasions and detected 10,041 fleas. Sevin and Dusta-cide suppressed fleas but only for 1 month. Neither Alpine nor Tri-Die had any noticeable, consistent effect on fleas. Fipronil suppressed fleas by 97-100% for 3 months. The residual effect of fipronil persisted for *12 months. Efficacy of fipronil seems comparable with DeltaDust, which exhibited a residual effect for *10 months in prior studies. Continued research is needed to optimize fipronil treatments for plague management on prairie dog colonies.

“…Experiments conducted on Norfolk sandy loam soil in North Carolina, U.S.A., showed that carbaryl incorporated into the top 6 in. of soil at 3, 9 and 27 pounds/acre was completely degraded within 40 days, and the half-life of carbaryl was demonstrated to be approximately 8 days at all concentrations studied (Johnson & Stansbury, 1965)-Experiments were conducted at the I.R.R.I. farm (on Maahas clay soil, pH = 6 -5 , O.M.…”

Effects of Lindane and Carbaryl on Insects, Soil and Plant Nitrogen, and Grain Yield of Rice

1967

Experiments were conducted during three crop seasons to determine the effects of lindane and carbaryl, applied to the irrigation water or incorporated in the soil, on the control of insects, on the nitrogen status of the soil and plant, and on grain yield of lowland rice. In two crop seasons the highest grain yield was obtained from three applications of lindane to the irrigation water and carbaryl sprays at 7-to 10-day intervals, and in the third season from 20 kg/ha, carbaryl incorporated in the soil without any lindane treatment or carbaryl spray. In two seasons, soilincorporated carbaryl at 20 kg/ha, active ingredient gave a significantly higher yield than the no-insecticide control, and in one season the increase in grain yield was just below the significant level. Most of the grain yield increase with 20 kg/ha, carbaryl incorporated into the soil was caused by better control of stem borer and leafhopper and a significant reduction in virus infection.
