Abstract

Conditions inside the gr eenhouse are different from open field. So, the conventional sprayers, such as the self-propelled or tractor mounted boom sprayers, are not suitable for the greenhouse conditions, due to their big sizes. A disc sprayer (ultra low volume) was developed, and its performance was investigated and compared to a conventional disc sprayer and different pesticide applicator types, motorized knapsack sprayer and Hydraulic sprayer (gun). The experiments were carried out at El-Gemmieza Research Station during 2007/2008 season. The results showed that the proper unit to execute the spraying operation under greenhouse conditions is the disc sprayer after development. It has given the lowest values of volume median diameter VMD (65µm), percent of plant damage (1.26%) and highest values of number of droplets/cm² (295) and fungicide efficiency (86.33%)
