Compliance with the “4 right” principle in pesticide using of decorative tree planters in Nam Phong village, Nam Dinh province, Viet Nam

The objective of the study is to describe the real situation of appliance with the “4 right” principle of planters and to study the impact of this compliance on safety and effectiveness. A cross-sectional study was designed in order to satisfy the aims of the study. Subjects are planters who have committed to use pesticides at least 5 times in the past 3 months. By choosing 1 person in each household, the total of 220 respondents participated in the questionnaire survey designed on the Likert scale. Results of the study reveal that the level of compliance with the principle “4 right” of the subjects is in the average level with a score from 3.68-3.91/5. The criterion of using the right pesticide in the principle of “Correct pesticide” was most violated (36.8% of respondents rarely declared and occasionally complied). There is a positive relationship between compliance with “principle 4 right” and safety and effectiveness in pesticide using through people’s self-assessment. In conclusion, there was a widespread violation of the “4 right” principle of pesticide using. Communication and consultation programs on the use of pesticide for people should be maintained
