The disease is "Burnt rice" caused by Pyricularia grisea is the most important incident in the cultivation of the species Oryza sativa, variety "Capirona" in the Alto Mayo, The present study was conducted in the Estate EPARSA, sector Shica of San Juan de Tangumi, district of Causeway. Province of Moyobamba and Department of San Martin, considering the following objectives: to determine the fungicidal effect of the extract of liver in the control of P. grisea in rice (O. sativa) variety "Capirona", to perform the cost/benefit analysis of the treatments, help with techniques for ecological control of diseases for agriculture to be sustainable and to encourage the participation of the farmer in the execution of the project. The extracts were obtained from the following species Pilotrichella directed, Plagiochila porel/oides, Entodon beyrichii, Apometzgeria pubescen extracted from the sector San Mateo — Province of Moyobamba, with concentrations of (0,00%); (0,05%); (Or, 15%), And (0,25%). We used the experimental design of Blocks Completely Randomized with four repetitions. Were 13 applications after transplantation and 4 in a state of panicle, from November 2002 to march 2003. In the data analysis we used Analysis of Variance (ANVA), the benchmark multiple of DUNCAN in the cases that require it, and also the non-parametric test of Friedman when it is not possible to use analysis of variance, encbntró that the concentration of extract of liver; treatment T2 (Or, 15%) controlled the P. grisea, between the tenth to the fourteenth evaluation of data hojdplanta/treatment, which constitutes a control technique in the development of a sustainable agriculture; the treatments TO, Tl and T3 which received the highest degree of severity at the seventh evaluation (stem growth); in comparison with the treatment T2 (0.15%) of that obtained the greatest degree of severity in the first (seedling or transplant), and seventh assessment (macollamiento); the higher yield of rice is achieved in treatment T2 with 5132,64 Kg./ha and the lowest was Obtained in treatment TO with 4731,94 Kg./has. of paddy rice at 14 % moisture; the cost / benefit analysis indicates to us that in order to get greatest benefits is that to lower production costs (cost of the extract of liver).
