To am elevations from 20 m snm. It´s cultivate with banana of the variety clon Great Cavendish, it had as objectives: 1. Value the efficacy of biologics products and neem in the population regulation of R. similis in banana, 2. Relate the nematodes control with the rent and quality of the fruit and 3. Realize the economic analysis of the treatment by hectare. The nematodes control population Radopholus similis it realized by means of the application of commercials products formulates with emtomopatogens fungus: T1 BioAct (Paecilomyces lilacinus) 4 kg/ha; T2 Bio Act +Biotac (Paecilomyces + Trichoderma) 4 + 2 kg/ha, T3 Nemater (Myrothecium) 10 kg/ha. T4 Nematerr + Biobact (Myrothecium spp + Trichoderma sp) 10 + 2 kg/ha, T5 Nematron (Hidroxipropenal – Azadirachtina) 2 l/ha; T6 Nematron + Biobact (Hidroxipropenal– Azadirachtina + Trichoderma sp) 2 l + 22 kg/ha. T7 Absolute witness. It evaluated the initial population, and to the 30, 90 and 150 days after of application, growing index, raceme weight, pants numbers, calibration and maturation grade. The nematodes population has determined trough the analysis of the samples de roots to following the extraction for sieved continue method of Cobb; for establishing the initial population. It´s samples four plans for each experimental plot that which it shaped a sample. For the growing index has realize the calculation it took the values of the results from initial and finales population. The nematicides product is applied in plots of 20 x 25 m; to adding up 28, a cording the recommending quantity with pumping engine bag in semicircle form already of son, in three application cycles with intervals of eight weeks. The roots samples has took to 10 cm parallels between the son of succession that was more from elevation 1 m and the plant mother flowering recently; for this it excavated a hole of 20 cm wide by 20 long and 30 depth, it in taking all the roots inside this volume. In the test to realized the cultural works that correspond to technologic handling of cultivation. Once that it´s execute the physiological maturity of the experimental unites to proceed to your harvest. The results obtaining of the initial and finally population of the nematodes and subjecting to analysis of variant with transformation to log X. It didn´t give significant results for all the variables analysis for it that didn´t obtain evidences firms of that the fluctuation population has to the biologic action of the fungus entomopatogens or the neem. The variables raceme weight on the contrary has experiment an increase in all the treatments with respect to Absolute witness just as that it varied between 5 to 11 pounds for raceme; the same that maintenance in the future will compensate the phytosanitary control costs. |
