Spray Deposition on Citrus Canopies under Different Meteorological Conditions

Abstract

This article explored the effects on spray deposition of air temperature, relative humidity, wind velocity, wind direction, and leaf surface wetness (a function of temperature and relative humidity) commonly occurring during a 24-h period. The interaction of different spray volumes (470; 1 890; 4 700 L/ha) with the above meteorological parameters was studied. Samples were taken from citrus canopies from six radial locations at each of three heights.
