Efecto del quelato de cobre más agua ozonizada en el control de caracol manzana (Pomacea canaliculata) en el cultivo arroz de la zona de Salitre.

Abstract

The project was done at the site “La Victoria” located at km 38 of the Guayaquil - Salitre route, province of Guayas between November and December 2017. The purpose of this project was to evaluated the mortality of the apple snail (Pomacea canaliculata) under the effect of cooper chelate and ozonated water in the transplant stage of the rice crop. The test was made using a completely randomized block design with 4 treatments and 4 repetitions, where T1 corresponded to 1 liter of copper chelate in 200 liters of water, T2 corresponded to 2 liters of copper chelate in 200 liters of water, T3 to 1 liter of copper chelate plus ozonated water and T4 corresponded to 2 liters of copper chelate plus ozonated water. The comparisons between the treatments were made by means of Fisher's statistical significance test F at 5% probability. Finally, it was demonstrated that treatment 3 and 4 had a better result in the control of the apple snail with respect to treatment 1 and 2, it should be emphasized that the T4 treatment obtained the highest number of dead snails in each repetition.
