    Conocimiento sobre los métodos de control de plagas agrícolas de los productores de maíz en los cantones Quito y Patate: una comparación
    (2024-02) Lesano Yaguar, Kevin Javier; Vásquez Freytez, Carlos Luis
    Maize crop (Zea mays L.) has spread rapidly throughout the world and has become one of the main cereal crops worldwide. As in other important crops, the use of agrochemicals is the main method of pest control, however, little is known about the level of farmers' knowledge about the risk of this type of strategy. In this sense, this research aimed to diagnose the knowledge of agricultural pest control methods of corn farmers in the Quito and Patate cantons. A structured survey was applied to a sample of 40 respondents in each study area. Among the main pests in both areas represented by the fall armyworm (Spodoptera frugperda), cutworm (Agrotis spp.), slugs and aphids, chemical control being used as the main pest management method. According to the results, producers in both areas are unaware of or do not give importance to the risks associated with the excessive use of pesticides, such as problems to human, animal, soil and water health. In relation to the factors that determine this behavior, it is included that farmers consider that they are effective products for pest control and that, for Patate producers, they show a rapid effect in control. Finally, the almost total lack of knowledge on the part of farmers about the potential benefit of other strategies such as biological control, use of resistant varieties, among others, was confirmed. The design of training and awareness campaigns for corn producers is recommended to avoid damage to health and the environment. Keywords: pest control, sustainable strategies, corn, Patate, Quito

    Valoración del conocimiento de los productores de hortalizas sobre el manejo sustentable de plagas agrícolas en la parroquia Izamba
    (2023-03) Quiña Telenchana, Jessica Gabriela; Vásquez Freytez, Carlos Luis
    Agricultural production constantly faces phytosanitary problems, such as pest attacks, which put crop productivity at risk. Therefore, one of the most commonly used practices for pest management is the use of chemical pesticides despite the well-known negative effects on human health and the ecosystem. In the present study, an attempt to assess the knowledge of vegetable producers about the management of agricultural pests was made in the Izamba parish. For the study, a structured survey with open and closed questions was applied to the producers. A high percentage of farmers considered that, although there are benefits derived from the use of chemical pesticides, they also pointed out negative aspects such as the need for training for their management and that they are also potentially dangerous when handling them and harmful to the environment. Also, it was evidenced that farmers know about other control alternatives, since 71% of the respondents said they applied some other pest management alternative, among which they indicated the use of cultural practices, biological control practices and/or traps with pheromones, as well as the use of homemade botanical extracts. Given the importance of evaluating the level of knowledge of farmers about the risks of the use of chemical products in the management of agricultural pests, it is suggested to develop similar investigations in different agricultural items in the province of Tungurahua in order to develop strategies of education on the best use of this strategy.

    Diagnóstico del nivel de conocimiento de los productores de especies frutales sobre las alternativas convencionales para el manejo de plagas agrícolas en el cantón Patate
    (2023-03) Barrera Punguil, Bryan Steven; Vásquez Freytez, Carlos Luis
    The continuous crop production is frequently threatened by the presence of pests that can cause severe damage to agriculture with important economic consequences. Thus, the use of pest management tactics that are respectful of the environment and the health of both the farmer and the consumer is required. In this sense, in the present investigation a diagnosis was made on the level of knowledge of the producers of fruit species about the conventional alternatives for the management of agricultural pests in canton Patate. This research was carried out under a non-experimental, cross section through the application of a structured survey. Most of the farmers consider that there is not a high risk of the use of pesticides on the health of the people involved directly or indirectly with the agricultural production process. In the same way, most farmers do not perceive the risk of pesticides on the quality of environmental elements and natural enemies, health of domestic animals and wildlife. Concomitantly with the previous findings, it was found that most of the interviewees (71%) did not know and/or used other pest management practices other than chemical control during their last crop. Of the 26% that did apply an alternative method of pest management, they mainly used cultural practices, biological control, and the use of pheromone traps. The low level of knowledge that farmers have about alternative pest management strategies requires the implementation of training plans to show the benefits of biological control and other methods by demonstrating the proper use of these techniques.

    Diagnóstico del manejo sustentable de plagas agrícolas por los agricultores de la comunidad Manguihua Cochapamba Katitawa de la parroquia Salasaka
    (2022-09) Chango Sailema, Sandra Verónica; Vásquez Freytez, Carlos Luis
    The agricultural tradition of the Salasaka community is characterized by its ancestral heritage, closely linked to its natural environment, which is maintained from generation to generation for its economic development. However, agricultural production is based on the indiscriminate use of chemical inputs, agricultural mechanization and the intensification of monoculture, which reduce the productive capacity of agricultural land, and together produce soil degradation and water pollution. In this study, perception of farmers from Salasaka (province of Tungurahua) in relation to the use of chemical pesticides was evaluated, as well as their knowledge about the strategies of sustainable management of agricultural pests. For this, a cross-sectional study was carried out through the application of a structured questionnaire applied to agricultural producers of the Manguihua Cochapamba Katitawa Community, Salasaka. Among the results, 60% of the farmers considered that pesticides are effective for the control of pests and diseases, quickly, and also increase productivity and stimulate plant growth. However, farmers also perceive negative aspects such as high cost (73.3%), potential damage when handling them (46.7%) and causing damage to the environment (73.3%). Although a high proportion of farmers stated that they knew about sustainable pest control alternatives, a very low percentage said they had used this type of strategy. This highlights the need for the development and implementation of training that shows the potential of these sustainable practices in order to achieve environmentally friendly agriculture.
