Manejo del herbicida pretilachlor en el cultivo de arroz (Oryza sativa

Rice (Oryza sativa) is one of the most important foods worldwide since the majority of the population consumes it daily, which is why pretilachlor is a selective herbicide used mainly in rice cultivation to control a variety of weeds. It belongs to the group of chloroacetamides and is applied pre-emergence or early post-emergence. This research aims to describe the management of the herbicide pretilachlor in rice cultivation. This work was developed as a non-experimental bibliographic research using the analysis technique, magazines, current texts, articles, synthesis and summary of the collected data. The results obtained in the research show that the weeds controlled by pretilachlor are annual grasses, sedges and some dicotyledons. For the application of pretilachlor, various equipment is used, such as backpack sprayers, tractor-mounted sprayers and irrigation systems, ensuring uniform coverage. The effectiveness of pretilachlor in rice has been widely demonstrated in its mode of action which involves inhibiting the synthesis of essential fatty acids in weeds, thereby stopping their growth. It is essential to follow the dosage and application recommendations to avoid phytotoxicity in rice and minimize weed resistance with the appropriate equipment according to the size of the field and specific conditions since it is essential to maintain the effectiveness of pretilachlor and the sustainability of the crop. of rice.

El arroz (Oryza sativa) es uno de los alimentos más importantes a nivel mundial ya que la mayoria de la población lo consume a diario lo cual el herbicida pretilachlor es selectivo usado principalmente en el cultivo de arroz para controlar una variedad de malezas. Pertenece al grupo de las cloro-acetamidas y se aplica en preemergencia o postemergencia temprana. Esta investigación tiene como objetivo Describir el manejo del herbicida pretilachlor en el cultivo del arroz. Este trabajo se desarrolló como una investigación bibliográfica no experimental utilizando la técnica de análisis, revistas, textos actuales, artículos síntesis y resumen de los datos recopilados. Los resultados obtenidos en la investigación demuestran que las malezas que controla el pretilachlor se encuentran gramíneas anuales, ciperáceas y algunas dicotiledóneas. Para la aplicación del pretilachlor, se utilizan varios equipos, como pulverizadores de mochila, pulverizadores montados en tractor y sistemas de riego, garantizando una cobertura uniforme. La eficacia del pretilachlor en el arroz se ha demostrado ampliamente en su modo de acción que implica la inhibición de la síntesis de ácidos grasos esenciales en las malezas, lo que detiene su crecimiento. Es fundamental seguir las recomendaciones de dosificación y aplicación para evitar fitotoxicidad en el arroz y minimizar la resistencia de las malezas con los equipos adecuados según el tamaño del campo y las condiciones específicas ya que es esencial para mantener la eficacia del pretilachlor y la sostenibilidad del cultivo de arroz.
