• Fungi,straminipila,bacteria,virus: attackbefore/afterharvest.• Nutritional/commercialvalue may bedisminished.Objetives• To detect diseases on farm productspostharvest• To do presumptive/symptomaticsymptomatic diagnosis• To find out possible pathogens associated

Materials And Methods• Samples collected at super/minimarket,trucksand individual street sellers (2009-2010) 2010) in Sto.Dgo.• Produces came from different producing regions• Diagnosis based on typical symptoms/signssigns• Samples with unknown / atypical symptomstaken to lab.

Discusion• field attacks of pathogens continue at postharvest along with weak/opportunist microorganisms•Produces less attractive•Market/nutritional value is reduced•Insect / mechanical damages, unsuitable store conditions might riseboth attacks of pathogens and physiological deterioration of products.
