AREVALO C, Aracelly; BACCA, Tito  and  SOTO G, Alberto. DIAGNOSTICS OF PESTICIDES USE AND MANAGEMENT IN PRODUCTIVE GREEN ONION Allium fistulosum FARMS IN THE MUNICIPALITY OF PASTO. Luna Azul [online]. 2014, n.38, pp.132-145. ISSN 1909-2474.

Pests and diseases control in green onion cultivation in the department of Nariño is characterized by the use of chemical control. Therefore, the objective of the investigation was to identify the use and management conditions of pesticides on this crop in the small township of Buesaquillo, municipality of Pasto. To determine the type of products used, an empty agrochemical containers collection was carried out during six months. Two hundred surveys, with 38 questions related to socio-economic aspects, crop management, pesticide use and management and its potential risks, were carried out in the study zone. The data were submitted to multiple correspondence analyses. A total of 4710 empty containers were recollected, of which 46.3% corresponded to fungicides, 12.4% to fertilizers, and 9.3% to insecticides. The main criterion of application was the one recommended by the agrochemicals warehouse sale (72%); frequency of application depends on environmental conditions ranging between 8 and 15 days, and the grace period in 80% of the surveys is 15 days prior to the harvest. 74% of farmers exposed to pesticides are men and most of them (85.5%) have completed their primary school studies; 53.5% do not understand the product's label, some of them (19%) claim to have suffered intoxication symptoms and most producers (70%) burn the pesticide containers. Under the conditions of this study it can be concluded that the use of pesticides is similar among the surveyed farmers, and is characterized by inadequate management, which puts farmers' health at risk and threatens this agro ecosystem equilibrium.
