“…Bromilov stated that with moderate rainfall the major loss of the chemical in the upper 10 cm of his sandy loam soil was caused by degradation but Bull et al (1970) suggested that residues of these highly water soluble substances dissipate because of leaching or because volatilization of aldicarb equivalents increases with greater moisture. Coppedge et al, (1970) found more movement in coarse sand than in clay or loam while in muck samples the aldicarb equivalents were distributed equally in all five layers examined.…”

“…Therefore the degradation rate of pesticides would be expected to be reduced in low-moisture soils (Bull et al, 1970;Jones & Norris, 1998). reported that the oxidation and hydrolysis rate of aldicarb in sandy loam soils containing 5% water was lower than the rate in soils containing 10% and 15% water.…”

“…reported that the oxidation and hydrolysis rate of aldicarb in sandy loam soils containing 5% water was lower than the rate in soils containing 10% and 15% water. In completely dry conditions, aldicarb or its toxic derivatives were relatively resistant to chemical decomposition (Bull et al, 1970). However, such a situation would probably never occur in the field.…”

Accelerated microbial degradation (AMD) of organophosphate and carbamate nematicides is a phenomenon whereby biodegradation in the soil is increased, leading to a dramatically shortened persistence of nematicides. More intensified agriculture practices in South Africa in response to the future demand for food may lead to increased pest and disease pressure, which in turn will lead to more frequent pesticide application. The same principle applies to plant-parasitic nematode control practices, and the overuse and misuse will have a pronounced effect on the enhancement of AMD. With limited management options available, the responsible use of nematicides becomes more pertinent. Producers should be aware of the problems associated with multiple soil applications of organophosphates and carbamates against plant-parasitic nematodes. This article reviews factors contributing to the AMD of carbamate and organophosphate nematicides in soil and makes practical recommendations to avoid the occurrence of AMD in vineyard and orchards.

“…At pH 7.5 or less, and tempera tures between 5°C and 15°C, the sulfoxide has half-lives of 1-2.2 years and the sulfone has half-lives of 0.3-2.5 years; degradation is more rapid with increasing pH (29). Aldicarb sulfoxide and aldicarb sulfone hydrolysis products are nontoxic compounds (30)(31)(32).…”

EPA began to emphasize work on ground water contamination by pesticides in 1979. Much monitoring has been done in this area since 1979, mostly by state agencies and, to a lesser extent, pesticide registrants, university scientists, and EPA.To date, as a result of agricultural use, a total of 12 different pesticides have been found in the ground water of 18 different states. The 12 chemicals represent seven different chemical classes.Despite significant limitations in the laboratory and field data, some generalizations about the key environmental fate parameters and field conditions are made which aid in predicting which compounds will leach to ground water. Use of pesticides in the production of U.S. agricultural commodities is widespread; 370,455 metric tons of active ingredients, which corresponds to 70.3% of the total poundage of pesticide active ingredients used in the U.S., were applied to agricultural land in 1982 (1). With the worldwide increase in need for food and fiber (2), use of pesticides is expected to increase (3). Since nearly half of the U.S. population relies on ground water as their source of drinking water (4), potential for contamination of ground water due to pesticide use must be considered in the registration process.In this paper, the environmental fate characteristics of those pesticides found to date in ground water as a result of agricultural use are summarized. Monitoring data are also summarized. From those summaries, and information on the sites of ground water contamination, it can be concluded which combination of pesticide chemical characteristics and use sites represent a high potential for ground water contamination.Other aspects of assessing potential for ground water contamination, such as study design and modeling, as well as interpretations of sorption, volatility, and photolysis data are also discussed.This chapter not subject to U.S.
