ORIGINAL PAPER
Effect of fluid flow through control valve in sprayer instalation on viability of entomopathogenic nematodes
Journal of Research and Applications in Agricultural Engineering 2011;56(1):19-25
KEYWORDS
ABSTRACT
A flow of liquid containing entomopathogenic nematodes through gap of control valves in sprayer installation can cause death of apart of these living organisms. The range ofthose damages were assessed using a relative nematode viability Experiments were carried out with multiple flow of nematodes through valve gap when the liquid pressures were equal to 0,50; 1,05 and 1,60 MPa. The least fall of viability was observed when the value of pressure was 0,50 MPa and the liquid flow was equal to 0,33 dm3-s-1. Generally there was observed that higher values of the liquid pressures and smaller values of liquid flow ranges caused an appreciable decreasing of relative nematode viability.
