Esta plaga ha reducido significativamente la productividad del arroz en todo el mundo. El presente trabajo se realizó en vía Salitre-Baba, en el km 38 en la provincia del Guayas, Ecuador 2020. Fue un ensayo experimental a nivel de campo donde se aplicaron diferentes dosis (un litro de quelato de cobre + agua ozonizada/hectárea) y (dos litros de quelato de cobre + agua ozonizada/hectárea). Para lo cual se utilizó un diseño de bloque completo al azar (DBCA) y 4 tratamientos, 1 testigo y 4 repeticiones. Una vez cosechado el arroz, los datos estadísticos relacionados con el rendimiento fueron recolectados. Los resultados demuestran que el rendimiento no se ve afectado por la aplicación de quelato de cobre y ozono y aunque no hubo diferencia significativa entre todos los tratamientos se observó que el mejor tratamiento fue el T4, que corresponde a la dosis de 2 L ha-1 de quelato de cobre mezclado con agua ozonizada con 2 ppm de concentración donde el rendimiento fue de 3 827.5 ±877.8 kg ha-1, mayor comparado con el T5 (testigo) que reflejo un rendimiento de 1 488.7 ±596.4 kg ha-1 significativamente inferior por la presencia y efectos del caracol. Se concluyó que el quelato de cobre con el agua ozonizada puede controlar el caracol manzana en el cultivo del arroz, además se observó un aumento de rendimiento en el grano.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The golden apple snail (Pomacea canaliculata) (Lamarck) is the pest that has caused the most problems in recent years in rice crops. This pest has significantly reduced the productivity of rice worldwide. The present work was carried out on the Salitre-Baba highway, at km 38 in the province of Guayas, Ecuador 2020. It was an experimental trial at the field level, where different doses were applied (one liter of copper chelate + ozonated water/hectare) and (two liters of copper chelate + ozonated water/hectare). For this, a randomized complete block design (RCBD) and 4 treatments, 1 control, and 4 repetitions were used. Once the rice was harvested, statistical data related to yield were collected. The results show that the yield is not affected by the application of copper chelate and ozone and although there was no significant difference between all treatments, it was observed that the best treatment was T4, which corresponds to the dose of 2 L ha-1 of copper chelate mixed with ozonated water with 2 ppm concentration, where the yield was 3 827.5 ±877.8 kg ha-1, higher compared to T5 (control), which reflected a yield of 1 488.7 ±596.4 kg ha-1 significantly lower due to the presence and effects of the snail. It was concluded that copper chelate with ozonated water can control the golden apple snail in rice crops, and an increase in grain yield was observed.]]></p></abstract>
