Lisää tagi | Yhteenveto: | The tomato (Solanum lycopersicum) belonging to the Solanaceae family is one of the main products in the Ecuadorian diet, the area sown in Ecuador is 2609 ha, with a production of 50,552 tons per year. In order to minimize the use of chemical insecticides and in turn contribute to the control of insects-pests, the need arises to look for products of natural origin that have insecticidal effects and that are not harmful to both the environment and the human being. Under this context, the study of evaluating different doses of pyrolenoid acid for the control of the bold (P. longifila) in the tomato crop (S. lycopersicum) in response to yield was proposed. Since its first report, in 1986, it has been considered an entomological problem of care, for which the following objectives were raised: Check the dose and effectiveness of pirolenoid acid in the repellency and control of the bold in the tomato crop, evaluate the agronomic behavior and yield of the tomato crop and determine the treatment with the best economic response in the crop. This research was carried out at the “La María” Experimental Campus Farm, located in the Mocache canton, kilometer 7 1/2 of the Quevedo - El Empalme road, Los Ríos Province. For its realization, tomato plants were used which were treated with the doses of 1, 2 and 3 lt of pyrolene acid, compared to a commercial control and an absolute control made up of water. After the analysis and tabulation of the data obtained, it was given as evidence that the application of pyroliginous acid in dosages of 3 lt / ha registered a percentage of 2.25% of aggressiveness of bold in flowers and fruits. The same treatment of 3 lt / ha presented the highest yield in the first crop with 8.35 tn / ha and the second best yield in the two following crops. In conclusion, the pyrolenoid acid treatment made up of 3 lt / ha remarkably exerted repellency towards the pest. Keywords: Pyroliginous acid, Tomato, Bold |
