Hidrolik Memelerin İlaç Uygulama Performansını Etkileyen Faktörler

Abstract

In the agricultural production, widely used method against disease and harmful factors is chemical control method.
The achievement of chemical control is dependent sufficiently on transportation of pesticide active ingredient to the
target and deposition on the target surface. Spray units having different design properties are developed for improving
spray application performance. At the present, the most preferred spray units are hydraulic nozzles used on conventional
sprayers. But when the operational parameters like spray height, spray pressure, travel speed on spraying are
inappropriate, application performances of spray nozzles are decreased. These cases cause to decrease biological
activities, increase pesticide losses and environment pollution. Spray application performance is under the influence of
internal and external factors. Internal factors have controllable or changeable properties and compromise constructive and
operational properties of spray units. External factors are uncontrollable properties and include meteorological conditions
and vegetable properties. Spray application is more difficult and complex, because the interactions between these
properties are important. Therefore, spray application technique must be investigated extensively. In this study, some
factors effecting spray application performance of hydraulic nozzles are compiled in the light of the literature.
