Phytosanitary compliance has returned to the center of concerns for the Brazilian soybean chain after recent episodes of retention and return of shipments destined for China. In response to this scenario, the Brazilian Association of Soybean Producers (Aprosoja Brasil) launched this Tuesday (02) a guide aimed at identifying and managing quarantine pests, organisms considered to be of high economic risk to national agriculture.<\/p>\n
The material brings together technical guidelines for rural producers and reinforces the adoption of autumn management as a preventive tool to reduce the incidence of these pests in crops. During the launch, training sessions on good agricultural practices and an awareness campaign on the economic and commercial impacts associated with the topic were also promoted.<\/p>\n
Risk to production and exports.<\/b><\/b><\/h4>\n![](\"https:\/\/i0.wp.com\/opresenterural.com.br\/wp-content\/uploads\/2026\/06\/Cartilha-traz-exemplos-de-plantas-daninhas-consideradas-quarentenarias.jpg?resize=325%2C170&ssl=1\")
<\/p>\nThe booklet provides examples of weeds considered to be quarantine plants.<\/p>\n<\/div>\n
According to the Ministry of Agriculture and Livestock (Mapa), quarantine pests are organisms such as insects, fungi, bacteria, viruses, or weeds that can cause significant damage to agricultural production and compromise international trade. For this reason, they are subject to official prevention, control, or eradication measures.<\/p>\n
Mauro Ant\u00f4nio Rizzardi, an agronomist with a doctorate in Weed Science and a professor at the University of Passo Fundo, explains that these pests are classified into three categories: absent quarantine pests, present quarantine pests, and regulated non-quarantine pests. Each requires specific monitoring and control protocols.<\/p>\n
Concerns have intensified in recent months after approximately 20 ships carrying Brazilian grain were returned or detained by Chinese authorities due to the detection of weed seeds and traces of pests not present in that country.<\/p>\n
The financial impact of these occurrences is significant. In addition to the logistical costs for redirecting or reprocessing cargo, which can reach approximately 69,000 tons per vessel, the sector also faces contractual penalties, canceled deals, and reduced export premiums.<\/p>\n
There are also repercussions for the country's international reputation. Since approximately 801% of Brazil's exported soybeans are destined for China, phytosanitary incidents can result in more stringent inspections, delays in cargo unloading, and a loss of competitiveness compared to other global suppliers.<\/p>\n
Autumn management gains relevance.<\/b><\/b><\/p>\n![](\"https:\/\/i0.wp.com\/opresenterural.com.br\/wp-content\/uploads\/2026\/06\/Lancada-nesta-terca-feira-02-cartilha-traz-informacoes-sobre-pragas-quarentenarias.jpg?resize=224%2C300&ssl=1\")
<\/p>\nReleased this Tuesday (02), the booklet provides information about quarantine pests.<\/p>\n<\/div>\n
The guide highlights autumn management as one of the main strategies to reduce the presence of quarantine pests. This practice consists of adopting phytosanitary measures during the off-season, between the harvest of summer crops and the beginning of the next production cycle.<\/p>\n
The goal is to eliminate weeds, volunteer plants, and other host plants that serve as shelter for pests and diseases. This reduces the seed bank of invasive plants and interrupts the reproductive cycle of organisms that can compromise grain quality and future productivity. \u201cThe introduction of new plant species into a country's production system is a matter of national sovereignty. Any plant part, pollen, seed, or propagule that can survive and reproduce in the environment is a potential harm to both the local production system and the export process of agricultural production,\u201d states Rizzardi.<\/p>\n
The concern is even greater given the projections for the next harvest. Brazil estimates harvesting more than 350 million tons of grains in the 2026\/27 cycle. In this context, losses between 10% and 15% associated with inadequate pest management could represent losses in the billions for the sector.<\/p>\n
Commitment to the reputation of Brazilian soybeans<\/h4>\n
According to Fabr\u00edcio Morais Rosa, executive director of Aprosoja Brasil, recent incidents involving exported cargo demonstrate that attention to phytosanitary requirements has become a strategic requirement for maintaining buyer markets. "With this guide, Aprosoja Brasil will continue its commitment to alerting producers about the misidentification of quarantine pests in order to maintain the high reputation of Brazilian soybeans among foreign buyers," he emphasizes.<\/p>\n
Monitored pests<\/b><\/b><\/h4>\n
Among the pests classified by the Ministry of Agriculture as quarantine pests are the Hindustani Mite, the Mango Seed Borer, Citrus Canker, Grapevine Canker, European Canker of Pome Fruits, Citrus Greening, the Carambola Fruit Fly, Moko Disease of Bananas, Witches' Broom of Cassava, and amaranth species considered difficult to control and with high invasive potential.<\/p>\n
Monitoring these occurrences is considered essential to preserve crop productivity and ensure the continuity of Brazilian exports in a market that is increasingly stringent in terms of sanitary requirements.<\/p>\n<\/div>\n
