Summary of Controle de pragas no milho com uso de inimigos naturais - Rio Grande Rural

00:00:00 - 00:05:00

In the YouTube video "Controle de pragas no milho com uso de inimigos naturais - Rio Grande Rural," the speaker highlights the adoption of integrated pest management practices using natural enemies for pest control in agriculture, specifically in the production of trigo (wheat) in Minas Gerais, Brazil. This approach contributes to environmental sustainability and cost reduction by reducing the use of agrotoxins and promoting healthier crops. The Brazilian Agricultural Research Corporation (Embrapa) showcases the use of beneficial insects like ladybugs and parasitic wasps, such as Trichogramma, which act during the critical stages of pest development and exclusively feed on a mixture of corn and wheat flour. Farmers can produce Trichogramma on a large scale using bioreactors, making it an efficient and profitable solution for pest control. The use of natural enemies for pest control not only benefits the environment but also preserves the health of farmers and applicators by reducing chemical exposure. The speaker emphasizes the importance of preserving habitats for beneficial insects and monitoring pest populations to effectively control infestations.

• 00:00:00 In this section of the YouTube video titled "Controle de pragas no milho com uso de inimigos naturais - Rio Grande Rural," the adoption of good practices for pest control contributes to environmental sustainability and cost reduction in agriculture. The integrated pest management concept, developed over many years, aims to produce healthier and more environmentally-friendly crops. The Brazilian Agricultural Research Corporation (Embrapa) showcases this practice on properties in Minas Gerais, emphasizing that applying pesticides is not the only solution. Instead, Embrapa has technologies to reduce agrotoxin use and ensure sustainable agricultural production. The benefits of integrated pest management extend beyond the environment, as these methods are efficient and profitable for farmers. The foundation of integrated pest management includes four elements: exploiting natural pest control, monitoring populations, and understanding the biology and ecology of crops and their pests. The concept of biological control, a crucial aspect of integrated pest management, has gained significant traction in the last few decades, particularly with the advancement of knowledge about the parasitic wasp Trichogramma. This wasp, which occurs worldwide, is produced in laboratories from a mixture of corn and wheat flour. By creating a bioreactor, farmers can produce the wasp on a large scale at a reduced cost. The demand for biological control methods, including Trichogramma, is increasing globally, making it a valuable market opportunity for Brazil. Trichogramma, which originated from a bioreactor, acts during the most critical stages of pest development, such as the egg stage, and it exclusively feeds on the mixture of corn and wheat flour. Therefore, using Trichogramma in the field ensures that pest damage is prevented, and it is particularly effective against Lepidopteran pests, such as the corn earworm. This method can be applied to various crops, including corn, soybean, cotton, and tomato. In Brazil, a farmer can independently build a bioreactor for Trichogramma production with minimal effort.

The Minas Gerais Association of Algodão (cotton) Producers, which is a cooperative of farmers, is preparing to produce wheat for this purpose in a culture known for high pest infestations and heavy chemical application. The benefits of biological pest control include maintaining the health of farmers and applicators, as well as reducing environmental issues such as residues. The speaker emphasizes the importance of preserving habitats for beneficial insects, such as flowers that offer nectar and pollen, and the need for farmers to monitor the presence of the corn earworm and control it using natural enemies like the ladybug known as the "tesourinha" and parasitic wasps. These natural enemies act during the early stages of pest development, preventing significant damage to the plant.
