The effect of liquid filtering parameters on insecticidal nematodes survival (viability) – biological plant protection product
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 3
Abstract
The described research dealt with the viability of insecticidal nematodes contained in the spray liquid flowing through filters used in spraying machines. Steinernema feltiae entomopathogenic nematodes were used in the research. The liquid was filtered using two filters mounted in spraying machines with 50 and 100 mesh number. Concentration of nematodes in the liquid was: 1 million and 2 million in 1 dm3 water. The liquid flowed at three pressure values: 1x105, 2×10 5 and 4×10 5 Pa. Significance of nematodes loss with the following liquid flow was observed: through 50 mesh filter (at pressure 4×10 5 Pa) and through 100 mesh filter (at all flow pressure values).
