Compatibility between bioinputs and chemical products has become a more prominent topic in agriculture as farmers seek greater efficiency in spraying. According to Fernando Souza, founder of Ag4study, compatibility cannot be generalized because chemical formulations may differ even with the same active ingredient, while biological inputs also depend on the specific strain of each microorganism. He says a mixture should only be considered compatible when the biological input maintains its development in the presence of all products in the tank mix. He also warns that compatibility tables may not reflect real application conditions. (Ag4study)

State of Rio Grande do Sul’s Agricultural Defense Authority has launched a task force to prevent the entry of giant pigweed (Amaranthus spp.) into the State after a confirmed occurrence of the weed was identified on a farm in Campo Erê, in the western region of the State of Santa Catarina, about 100 km from the border with Rio Grande do Sul. According to the authorities, the response includes a phytosanitary alert, farm visits, inspection of agricultural machinery, guidance on certified seeds, quarantine and eradication measures at the affected site, surveys in neighboring areas and outreach to farmers for the immediate reporting of suspected cases. Considered highly aggressive and difficult to control, the weed can grow up to four centimeters per day, produce between 100 thousand and 1 million seeds per plant, and cause significant losses in crops such as soybean and corn.

Bioinputs still have low adoption in the south region of the State of Rio Grande do Sul, despite their potential to reduce costs and emissions in agriculture. According to researcher Maria Laura Turino Mattos, the technology is already well established in other regions of the country, but still faces cultural resistance among farmers in the State, even with scientific backing and official registrations. (Embrapa)

A research concluded that the silverleaf whitefly Bemisia tabaci MEAM1 can complete its life cycle on eucalyptus genotypes under controlled laboratory conditions. Development was faster and viability was higher on soybean, while Eucalyptus camaldulensis showed intermediate performance and the hybrid Eucalyptus urophylla × Eucalyptus grandis had a longer cycle and lower survival. The authors note the findings are still preliminary, but they indicate that eucalyptus may serve as a host in forest and agroforestry systems. (Esalq; Agricultural and Forest Entomology)

Terra Agro Holding has announced changes in its corporate governance and executive structure as part of its 2026 expansion plan.

Delays in pesticide registration continue to drive lawsuits in Brazil, according to an analysis by AllierBrasil. Although in 2025 there was a record number of approvals, reaching 912 products, the average approval time for formulated and technical chemical products remained above five years, pushing companies to seek lawsuits to speed up regulatory assessments. According to Flavio Hirata, partner at the consulting firm, lawsuits are no longer an isolated practice and have become part of the regulatory strategy of the sector amid low predictability and slow processing times. “As of April 22nd, 2026, Anvisa approved 47 toxicological evaluations of pesticides in accordance with court decisions. Data from Ibama are not yet available”. (AllierBrasil)



Latin America

According to Roberto Muñoz, member of AgroCare, geopolitical pressure and changes in the global market have once again raised agrochemical costs and increased pressure across the sector’s value chain. According to him, higher energy, logistics, and input costs, combined with Asia’s strong weight in global supply, already require earlier purchasing and greater strategic adaptation in Latin America. (AgroCare)

Syngenta obtained in Argentina the first commercial approval for the herbicide metproxybicyclone, a new active ingredient aimed at controlling resistant grass weeds in soybean and cotton. The molecule was developed to target weeds resistant to widely used herbicides such as glyphosate and clethodim. (Syngenta)

In Argentina, rising prices of fertilizers are already putting pressure on wheat ahead of planting for the next crop. Urea prices have nearly doubled since late February, reaching around US$ 1,000 per tonne, prompting farmers to reconsider fertilizer use and, in some cases, shift toward alternative crops such as barley or oats. The Rosario Board of Trade said the country harvested a record 29.5 million tonnes of wheat in the last season, but higher urea costs could weigh on the production outlook for the new crop. (Rosario Board of Trade)

Authorities from 19  provinces in Argentina met in Paraná, the capital city of Entre Ríos province, for the Third Working Meeting on phytosanitary packaging recycling under National Law No. 27279. The event, promoted by the civil association Campo Limpio, discussed challenges to consolidate the circular economy model, focusing on traceability, interjurisdictional movement of recovered plastic and cultural change in the proper handling of containers. According to participants, adapting the system to different territorial realities and strengthening shared responsibility between the public and private sectors will be key to expanding the system across the country. (Campo Limpio)

In Mexico, the global fertilizer crisis is already pushing prices higher and increasing risks for food production. According to Juan Carlos Anaya Castellanos of the Agricultural Markets Consulting Group, between February 20th and March 27th, urea prices rose 25.8%, diammonium phosphate 26.4% and monoammonium phosphate 28.7%. Mexico consumes more than 5.5 million tonnes of fertilizers per year and relies heavily on imports, which heightens its exposure to the war in Iran, rising oil prices and tighter global supply.
