We assessed the situation of endosulfan residues in cotton fields after the endosulfan ban came into effect and the current knowledge,attitude,and practice(KAP)of cotton farmers on the phase-out of endosulfan and the application of alternative technologies.Topsoil samples(n=91)of cotton fields were collected from the major cotton-producing areas in China,namely the north-west inland cotton region,and the endosulfan residues were analyzed.A KAP survey was carried out for cotton farmers,and 291 questionnaires were distributed.The influences of gender,age,education background,cotton planting years,publicity and training,income sources,and other factors on cotton farmers'KAP were analyzed.The results showed that endosulfan sulfate was the main endosulfan residue in the soil,followed by β-endosulfan and a-endosulfan,the average residual contents were 0.569,0.139,and 0.060 μg/kg,respectively.The results of the KAP study showed that cotton farmers scored low on knowledge about the phase-out of endosulfan and the application of alternative technologies but high on attitude and practice.The number of family members,years of cotton planting,age,and the cotton-planting area had different degrees of influence on KAP scores.The training could significantly improve the KAP scores of cotton fanners;training should be more targeted and designed reasonably for key groups,such as men and the population under 30,followed by training them to use pesticides safely.For large-scale cotton growers,training should focus on green prevention and control technologies.
