“…Previous experiments with pyrethroids have reported that a large proportion (>60%) of these insecticides may remain sorbed onto the glassware walls of the tubes used for batch assays and centrifugation (Zhou et al, 1997;Ali and Baugh, 2003). The use of Teflon tubes (data not shown) also resulted in pesticide sorption on the walls, in agreement with previous results (( House and Ou, 1992;Koskinen et al, 2006).…”

“…The use of Teflon tubes (data not shown) also resulted in pesticide sorption on the walls, in agreement with previous results (( House and Ou, 1992;Koskinen et al, 2006). We then examined a possible relationship between the relative amount of pesticide sorbed on the glassware and the composition of the background solution, because some reports had indicated that the extent of sorbed pesticide on the laboratory glassware was independent of pH, ionic strength and DOC (Zhou et al, 1997;Ali and Baugh, 2003).…”

“…However, for highly hydrophobic compounds, such as organochlorine or pyrethroid pesticides, sorption on glassware walls could occur (House and Ou, 1992;Zhou et al, 1997).…”

“…Sarkar et al (1997) studied the contamination of organochlorine pesticides in marine and estuarine sediments along the west coast of India and reported the concentration of various pesticides like t-HCH, aldrin, dieldrin, endrin, and t-DDT among which the most predominant metabolites were found to be p, p-DDE and α-HCH in sediments from the mouth of different estuaries along the coast. Zhou et al (1997) studied the deabsorption of the tefluthrin insecticide from soil in simulated rainfall runoff systems kinetic studies and modeling and reported that about 95% of tefluthrin was sorbed onto soil particles, and a very small amount, about 3%, was left in the water. The partition coefficients (k p , k oc ) are lower than those previously determined for tefluthrin and λ-cyhalothrin due to the relatively high concentration of soil used in slurries.…”

In recent years, various environmental issues have aroused a concern on the pollution of pesticides in rivers and in their various intercompartments. Multiple residues of pesticides discharged from industries or as a result of extensive use of agrochemicals in agriculture have been monitored. These pesticide residues contaminate the river ecosystem and its intercompartments such as sediments, and aquatic biota, and make it harmful to humans when they contaminate food and drinking water. The pesticide contamination in water, sediments, and aquatic biota has been reported to be beyond the acceptable range. The most commonly found pesticides are organochlorine, namely, dichlorodiphenyltrichloroethane, hexachlorocyclohexane, endosulfan, heptachlor, lindane, dieldrin, aldrin, endrin, and others. The paper discusses the general description, classification, and toxicity of pesticides; it also aims to create public awareness among people and appraise them with various alternate methods to combat the problem of pesticide contamination. An attempt has also been made to elucidate the findings of various works on pesticides in aquatic system and to highlight the challenging aspects of pesticide contamination, which have not attracted the attention of investigators yet.

“…Insecticide wash-off also has important environmental and public safety implications (Pimentel et al 1992). Research to date on the impact of precipitation on insecticides has primarily targeted older chemistries, such as organophosphates and carbamates, or is in the context of cotton and Þeld crops (McDowell et al 1984;Willis et al 1992Willis et al , 1994Willis et al , 1996Zhou et al 1997). Thus, the information available for grape farmers about reapplication of insecticides after rainfall comes from either this limited research or "conventional wisdom.…”

Rainfastness and Residual Activity of Insecticides to Control Japanese Beetle (Coleoptera: Scarabaeidae) in Grapes

et al. 2011

Field-based bioassays and residue profile analysis were used to determine the relative toxicity, rainfastness, and field degradation over time of five insecticides from five insecticide classes on adult Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae), in grapes, Vitis labrusca L. Bioassays assessed Japanese beetle condition as alive, knockdown, or immobile when exposed for 24 h or 7-d field-aged residues of phosmet, carbaryl, bifenthrin, thiamethoxam, or indoxacarb after 0, 12.7, or 25.4 mm of rain had been simulated. We found that the two most toxic insecticides to Japanese beetle were phosmet and carbaryl, followed by bifenthrin, thiamethoxam, and then indoxacarb. The efficacy of phosmet decreased because of rainfall, but not because of field aging. The efficacy of carbaryl decreased because of rainfall and field aging. The efficacies of bifenthrin and thiamethoxam were not affected by rainfall but decreased because of field aging. The efficacy of indoxacarb was not affected by rainfall or field aging. This study will help vineyard managers make informed decisions on when reapplications of insecticides are needed with the aim of improving integrated pest management programs.
