In order to finding a new altemative for the preventive control of the Pyricularia grisea in cultivation of rice Capirona variety. it was carried out a comparative rehearsal with mixture of fertilizers leaves, (Microsul sulfur + Quelatos Zinc; Top Cop + Quelatos Zinc; Releaf + Stabilizer; X - Press + lgnite), with a chemical witness {Edifenfos 500 EC + Propineb 70% PM) and an absolute witness in the First floor May Region San Martín. The experiment was carried out in a soil {frank - clayly) lightly alkaline. Under the design of blocks completely at random {D.B.C.A) with 6 treatments and 4 repetitions. The fertilizers were applied in mixture and in different vegetativa period of the cultivation. The first two treatments (T1 and T2) they were applied in two stages of development of the plant, trillar and to the beginning of the cotton point; the T3 and T 4 were applied in three moments: triller, beginning of the cotton point and first heat, and the T5 were applied: trillar, to the beginning of the cotton point and the beginning of the spikelet. The best treatment for the control of Pyricularia was the T 4 (Microsul sulfur + Quelatos Zinc to 3,0 Lt/Ha + 0,6 Kg/Ha respectively) that controlled Pírycularia grisea satisfactorily. The best yields were obtained of the T4 Microsul sulfur + Quelatos Zinc to dose of 3,0 Lt/Ha + 0,6 Kg/Ha) with 7918,50 Kg/Ha of rice paddy when confronting with the witness (T6) that 7257,00 Kg/Ha obtained.
