Control: Spray Application

Plant Pathogens and their Control in Horticulture

Abstract

Spraying is the predominant method by which chemicals are used to control plant pathogens (section 6.4). This chapter describes, in nonengineering terms, the major components of a sprayer and some factors that affect their effectiveness. Basically a sprayer is a mechanical device whereby the manufacturer’s product is diluted by mixing with water or other fluid in a reservoir vessel and then forced by hydraulic or air pressure through one or more nozzles. These break up the liquid into droplets which are impelled to a target crop. Choice of sprayer depends on the total volume of spray to be applied, the area of crop to be covered, the habit of the crop—some sprayers are suited to low-growing vegetable crops rather than to trees or bushes—and crop location, that is, whether the crop is grown under protection or in the open field.
