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: t...
