“…Actinomycetes have also been reported as being capable of enhancing the degradation of carbofuran (Felsot et al, 1982) and of aldicarb (Kuseske et al, 1974) after repeated use. Actinomycetes ('ray fungi') are defined as a group of morphologically diverse, but usually filamentous, grampositive bacteria that sometimes have been classified as mitosporic fungi (Hawksworth et al, 1995).…”

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.

“…The inhibition of autotrophic, but not heterotrophic, nitrification in the presence of pesticides is well documented (Kuseske et al 1974, Smith & Weeraratna 1974, Gowda et al 1977. The present study showed that carbaryl and 1- naphthol inhibited both autotrophic and heterotrophic nitrification in bacterial cultures, but that the inhibition of autotrophic nitrification was more pronounced.…”

“…Here we examine the effects of the pesticide Aldicarb on the Ncycle within the framework of a multidisciplinary ecotoxicological study, which combines botanical, faunal, and microbiological investigations (Weidemann et al, 1985, 1 9 8 8 ) . The influences of Aldicarb on ammonifying and nitrifying microorganisms (Makawi et al, 1 9 7 9 ) , nitrogenase activity (Vlassak, 1 9 7 5 ) and nitrification (Sommer, 1970;Kuseske, 1974) have been documented by laboratory experiments. But nothing can be said about the consequences of these changes on the ecosystem level.…”

The N‐cycle of an Aldicarb‐contaminated [2.5 g · m−2 (a.i.)] soil cover of a newly graded rubble dump was investigated in order to judge the alterations of microbial nitrogen transformations at the ecosystem level. The pesticide reduced the kinetic parameters of nitrification (maximum activity and division rate) markedly, indicating severe damage to the nitrifying population of the soil during the first 16 weeks after its application. The degree of nitrification varied depending on the incubation conditions. Incubations in the field and under laboratory conditions without substrate addition showed negligible effects, whereas incubation with the addition of (NH4)2SO4 led to an intolerable reduction in nitrification. The consequences of these experimental results on the NO3 ‐N and NH4+‐N content of the soil solution were analyzed by simulating the N‐cycle using different sets of parameters (climatic factors, initial conditions). The results indicate that combining field and laboratory studies of microbial populations with a computer simulation model of the N‐cycle improves ecotoxicological risk assessment.
