Nematode fauna of paddy field flooded all year round
The rice paddy fields in Asia are being recognized as biodiversity hotspots. We have reported the seasonal dynamics of nematode communities in a conventional type of paddy field (CPF) in Japan, which
Non-target effects of herbicides on soil nematode assemblages.
The increase in bacterivore and decrease in fungivore abundance suggest that bacterivores are more tolerant and both fungivores and predators more sensitive to herbicide applications, and the decrease in predator abundance suggests that herbicide application disturbs soil food webs.
Non‐target effects of entomopathogenic nematodes on the soil nematode community
The results are the first to indicate selective suppression of plant-parasitic nematodes by entomopathogenic Nematodes, H .
The effects of glyphosate, glufosinate, paraquat and paraquat-diquat on soil microbial activity and bacterial, archaeal and nematode diversity
High-throughput phylogenetic marker gene sequencing revealed that none of the herbicides significantly influenced the richness, evenness and composition of bacterial and archaeal communities, and the ability of soil organisms to utilise 15 substrates was generally unaffected by herbicide application.
Impacts of Agricultural Pesticides on Terrestrial Ecosystems
Pesticides are toxic chemicals used to control pests, weeds and pathogens. Three quarters of all pesticides are employed in agricultural production, particularly in developed countries, in an effort
Effects of Pesticide Use on the Distributions of Grey Herons (Ardea cinerea) and Great Egrets (Ardea alba) in Rice Fields of the Republic of Korea
It is found that both grey herons and great egrets preferentially used transplanted fields and pesticide use in conventional rice fields directly suppresses the abundance of loaches, which frees the tadpole population from predation pressures and indirectly boosts their abundance in conventional Rice fields.
Effects of Pesticide use in Rice Fields on Birds
Understanding of the use and consequences to birds of pesticide applications in rice habitats is summarized and management practices that address adverse effects of pesticide use in rice fields include increased adoption of Integrated Pest Management principles and less toxic products.


The immediate and long-term effects of the herbicide MCPA on soil arthropods
Plots on arable land in southern England that had received an annual application of MCPA herbicide for 10 out of 13 years between 1951 and 1963, and similar untreated plots, were sampled to see
Plant and soil nematode population changes in wheat grown continuously in ploughed and in unploughed soil.
SUMMARY In general, more migratory plant-parasitic nematodes are found in soil under cereals drilled after ploughing than in unploughed land drilled after being sprayed with weed-killer; but some
The interaction of paraquat with soil : adsorption by an expanding lattice clay mineral.
Summary. Some characteristics of the interaction of paraquat with a dioctahedral montmorillonite have been studied by a combination of adsorption, radioisotope exchange, and X-ray diffraction
Pesticide Residues in Soil and Water
Large amounts of pesticides reach the soil, either as direct applications, from fall-out from aerial spraying, in rain or dust or from plant or animal remains which become incorporated with the soil.
Consequences of Periodic Applications of Copper Sulfate and Simazine for Phytoplankton Control in Catfish Ponds
Abstract Treatment of channel catfish (Ictalurus punctatus) production ponds with biweekly applications of 0.84 kg/hectare copper sulfate was ineffective in reducing phytoplankton density. Three
Measurement of Diversity
THE ‘characteristic’ defined by Yule1 and the ‘index of diversity’ defined by Fisher2 are two measures of the degree of concentration or diversity achieved when the individuals of a population are
