Effect of agrochemicals and bio-control productions on soil nematode community dynamics

Abstract

Abstract: Dynamics of soil nematode communities amended with agrochemicals and bio control preparations were investigated in a soybean field. The results showed that the frequency of plant non parasitic nematodes were obviously higher in soil amended with bio control preparations (Doufeng 1) than with urea and herbicide, however, that of plant parasitic nematodes exhibited an inverse trend.

Key words: Agrochemical, Bio-control production, Soil nematode, Community dynamics, photosynthetic gas exchange, rain-fed semi-arid area, chlorophyll fluorescence parameter, whole field soil-plastic mulching and bunch sowing, spring wheat, water use efficiency.
