THE IMPROVING PESTICIDE SPRAY NOZZLE FOR REDUCING THE LIKELIHOOD OF CHEMICAL EXPOSURES: A CASE STUDY OF A FARMER GROUP IN NAKHON PATHOM PROVINCE

Abstract

          The aim of the research is to improve the pesticide spray nozzle effectiveness. Analyze the decrease in the probability of chemical exposure when using pesticides both before and after the chemical sprayer is improved. This includes comparing the duration of time spent spraying, the volume of chemicals utilized, and the degree of exposure to chemicals (dose x time). In addition, find out how satisfied users are with the modified pesticide spray nozzle. To compare the pre- and post-experiment states, a single group quasi-experimental study was carried out. The example group was fifteen lemongrass producers utilized a form and a questionnaire to record the volume of liquid and time spent spraying pesticides with both the new (4 nozzle) and old (1 nozzle) spray guns. The study's findings showed that there was a significant statistical decrease (p < 0.05) in the average time and exposure dose and time when spraying with the new spray wand (4 nozzles) compared to the traditional spray wand (1 nozzle). There was also a decrease in the average amount of chemicals used when spraying with the new spray wand (4 nozzles) compared to the old spray wand (1 nozzle), but no statistical significance was found. After using the new injection tool, the majority report very high levels of satisfaction. To decrease the likelihood of additional chemical exposure, farmers should be advised to utilize the updated spray nozzle.
