Effectiveness of the application of mineral composts and biofertilizers for the control of Damping off (mal de talluelo) post-emergency, leaf blight and bacteriosis in pine caribe (Pinus caribaea)

Abstract

The fungus complex knows as damping off which causes the diseases known as ‘Mal de Talluelo’, Leaf Blight and Bacteriosis are presently the main phytosanitary problems of the genus Pinus in the Nicaraguan forestry sector. In this experimental investigation five treatments and the register of phytosanitary and phonological variables were used to study the control and effect in the development of the plant. The mineral composts and biofertilizers and the mixture of them studied in this investigation reduce the effect of these diseases for the plantula in condition of post emergency. The most effective is the application of a mixture of calcium, sulfocalcium and biofertilizers.
