Abstract

Agriculture is important in the food production sector and, to meet all the food demand of the population, the agricultural sector has modernized, using chemical control in agriculture to control pests, diseases and weeds. The objective of this work was to carry out a literature review on the problems of chemical control in agriculture from an agricultural perspective, in order to demonstrate how chemical control affects the agricultural sector. The present study was developed based on the review of literature and relevant research based on data from the years between 2015 to 2021, using articles and data in Portuguese on academic google, using chemical control problems and the perspective of agriculture with agrochemicals as keywords. To ensure the production of crops, crop management must be carried out correctly, and the control of pests, diseases and weeds that affect crops, for this, one of the methods used today is chemical control. With the use of chemical control, it made it possible for agriculture to achieve large productions with the benefits provided by its use in the control of pests, diseases and weeds, but it brought with it some problems in its use, whether in the social, environmental and social spheres. Due to the problems caused by the large use of agrochemicals and the search for sustainable rural development, other alternative methods are adopted in agriculture, such as biological and cultural control, which has brought many benefits, one of which is the reduction of the use of chemical control. In agriculture, reducing costs and helping to maintain the sustainability of the entire agricultural production sector. In this way, the inadequate use of chemical control has brought and brings problems, such as contamination and intoxication in the environment and to human beings, in addition to problems related to resistance to pests, diseases and weeds, making their control more expensive, requiring the adoption of other methods. control methods, such as cultural control and biological control, which have in themselves more sustainable characteristics, thus reducing the use of agrochemicals in agriculture and reducing the problems caused by their use.
