Guidelines on nozzle selection for conventional sprayers

Nozzle selection aims to maintain the balance between biological efficacy, human and environmental safety with particular respect to spray drift. This paper reports the development of a guide, for use in cereal crops, which a ims to assist farmers in their selection of nozzle type for use on conventi onal boom sprayers. The guide summarises nozzle type recommendations based on the information that was available in early 1999 from a review of releva nt literature and consultations with representatives of independent researc h organizations, nozzle manufacturers and agrochemical companies, both in t he UK and in Europe. As further information becomes available, particularly on the classification and efficacy of air-induction nozzles, the guide wil l need to be updated.
