The Effect of Different Dripper Properties on Entomopathogenic Nematode Application in Drip Irrigation
Abstract
There are many types of drippers with different
flow path length, flow path shape, filtration surface. EPN delivery performance
of the most commonly used four different types of drippers (in-line short path,
in-line long path, in-line cylindrical and on-line button) was examined with a
drip irrigation system in laboratory conditions. Under four different pressures
(0.5, 1, 1.5, 2 bar), EPNs were applied to 1-liter beakers with irrigation
system and discharged nematodes were counted under a stereomicroscope. The
effect of pressure on application and EPN mortality were also determined. The
results showed that there were significant differences between the discharge
ratio of EPNs from drippers. Among the four drippers, on-line button dripper sustained
the highest and fastest discharge ratio. Pressure alone had no significant
effect on delivering EPNs. However, it should be considered that long pressure
exposure may harm EPNs. Regarding our results, different irrigation drippers
have significantly different effects on EPN discharge ratio. Therefore,
optimizing drip irrigation systems for EPN applications may increase their
performance.
