Abstract

In Bam city Ommatissus binotatus is the most dangerous insect that attacks the date palm trees and the date growers suffer from the losses it forces to the yield every year. The ground and air spraying methods are not effective and each has their own weaknesses. The proposed method is spaying the tree from a height of one meter over the crown by a small sprayer on the tree. The sprayer is triggered by a remote control system. The sprayer was made and tested during this research. The sprayer was tested for droplet size and spraying pattern by two micro jet nozzles. The data were collected for three pressure levels and three distances from the sprayer at three replications. The droplet size distribution was measured by water sensitive papers. The data were analyzed by Image 1.38 X , Minitab and SAS software. The results showed that the sprayer equipped with the mini sprinkler micro jet nozzle produces a uniform spring pattern and uniform droplet size at all pressure levels. The sprayer is a promising devise for a sensor networking program.
