The influence of different doses of copper and organic substances on the genus composition and intensity of the occurrence entomopathogenic fungi in the soil

The aim of the study was to determine effect copper application in combination with organic materials on genus composition and intensification occurrence entomopathogenic fungi soil. three-year pot experiment carried out greenhouse conditions. set up a completely random design, taking into account two factors: dose fertilization. Soil samples for tests were collected third year experiment, spring (before beginning vegetation) autumn (after harvesting last crop). experimental plant cocksfoot, Amera cultivar. Entomopathogenic from individual research objects isolated by sowing selective substrate. results expressed as number CFUs each fungus 1 g presence Beauveria, Metarhizium, Cordyceps Lecanicillium found soils sites, where dominant Metarhizium spp. In period conducting research, level affected CFU different way, while at 200 mg/kg soil that did not show any toxic effects, even stimulated growth fungal colonies relation 100 mg/kg.
