The quasai study was performed in study group of klongtabak village, ladbuakao subdistrict in Sekhiew
district and control group of ta-ngoy village, Chanthuek subdistrict, Pakchong district in Nakhonratchasima
province. Chinese kale vegetable was purposively studied from cultivated farms and measured for pesticide
residues before and after intervention. 62 Chinese kale samples were collected, 31 each, from the study and
control farms, 1 sample from each vegetable plantation. About 80% of household volunteers (40 farmers) in
study group, were knowledge-educated and laboratory technology transferred of innovative test kits. The test
kit was used to screen 4 groups pesticide. % cholinesterase inhibition assay using spectrophotometer was
measured in all samples. Unsafe samples or suspected to be unsafe, were sent to test 4 groups pesticide
residues at central laboratory using gas liquid and high performance liquid chromatography. In addition to
laboratory test by researchers, technology transfer of self test laboratory in study farms obtained by training
agriculturists for safety monitoring by community. Regarding their laboratory competency, Proficiency test
samples were prepared and analyzed by researchers and also tested by farmers for inter-laboratory
comparison of innovative test kit. Small farm land pesticide safety was educated to agriculturists for safe farm
production with less toxic chemical use and awareness of proper cultivation practice and safety for consumers.
