With the objective of identifying the causal agent of the main fungous illnesses in Tomato (Lycopersicon esculentum) in San Martín county and to evaluate the effect of the food poisoned with different fungicides in the development of the pathogens, it was carried out the present investigation work, in the laboratory of Vegetable Sanity of the National University of San Martin; likewise for the test of the poison food it put on in mixture the following fungicides: Mancozeb, Benomil, Kresoxin metil, Tebuconazole, Tiofanate metil, Tiofanate metil + thiram, Triflumizole, Compropanil, Tolylfluanid, Plocloraz, Mancozeb + Benomil, Mancozeb + Metalaxil (48 - 10%) and Mancozeb + Metalaxil (64 - 8%). The mushrooms identified in the tomate cultivation were Fusarium oxysporum, Sclerotíum rolfsii, Altemate altemata, Cercospora solaní, Stemphylíum sotaní, Botrytis cínerea, Curvularia sp., Colletotrichum sp., Fu/va fu/vía and Verticillium sp. The fungicides that controlled better to the identified pathogens were Mancozeb, Kresoxin metil Mancozeb + Benomil and Mancozeb + Metalaxil which you/they didn't show growth sorne in the badges. Another of the fungicides that showed a good control was Triflumizole, only not controlling Fusarium oxysporum obtaining a growth of 1 O mm. Compropanil was the fungicide that controlled hardly to the identified pathogens, it only showed an effective control to Cercospora sotaní and it would A/temate solani.
