Contribución al control de Botrytis cinerea pers. en statice (Limonium sinuatum mill) variedad Midnigth blue

This work was outlined under the need of controlling the looses of statice (Limonium sinuatum) caused by patogend fungi, with emphasis to Botrytis cinerea. In soil samples, monitoring and affected plants, were obtained the fungi Botrytis cinerea, Fusarium sp, Alternaria sp and Cladospotium sp, causative of symptoms in stems, roots, leaves and flowers. Upon evaluating "in vitro" the antagonistic capacity of T. hamatum with the fungi, was observed growth inhibition ofthe patogens. The eficiency tests of the (fungicides) Iprodione (Rovral) and Captan (Orthocide), on the patogens and the antagonist, determined the lethal dose of these (1 gmllt) evaluated in the chemical and integrated treatments. In field was accomplished the assembly of the treatments (biological, chemical and integrated), to find the most effective in the control of the patogens. The efficiency was evaluated taking into account the production of export branches (550-560 gr.); national branches (twisted stems (decoloratedj); and branches lost by disease; the integrated treatment was the best, with a production of 1.8 branches/plant, followed of the Chemical trealment, with 1.62 branches/plant. The branches lost by disease were of 0.14 branches/plant in the integrated treatment and 0.26 branches/plant in the Chemical treatments-Biological and Chemical-Cultural. Treatment with smaller productivity was the Chemical-Cultural with 1.42 branches/plant.
