Sprayer periodic inspection is an important tool to improve pesticide application technology. The objective of this work was to evaluate the working conditions of boom sprayers in the region of Uberlândia - MG, and the inspection methodology for Brazilian conditions. The evaluations were done in farm properties randomly visited and consisted of a questionnaire filled out by the equipment operator and by the inspection team during the in loco visits. The items evaluated were: presence of leakage, hoses and connections, filters, anti-dripping gauges, spray nozzles, protection of mobile parts, guidance by track and environmental conditions monitoring. The results indicated the need to implement a frequent evaluation program for this equipment, since boom maintenance is being done incorrectly. The method used was adequate to evaluate the working conditions of the agricultural boom sprayers.
