The launch occurs as the 2025/26 cycle continues two consecutive seasons with favorable climatic conditions, following the 2024/25 harvest—among Brazil’s largest volumes historically. However, grain prices declined sharply over twelve months, directly impacting planting area decisions, technology investments, and management strategies.
“Among the principal diseases affecting Brazilian rice, blast stands out for damage potential,” said Matheus Scherer, BASF Rice Crops Marketing Manager. “Caused by the fungus Pyricularia grisea, the disease can compromise practically all production when inadequately managed. In extreme situations, losses can reach levels near 100%, depending on varietal susceptibility, climatic conditions, and absence of efficient chemical control.”

Brown spot, caused by Bipolaris oryzae, shows more regional distribution, while maintaining economic relevance. In inadequately managed fields, losses range between 20% and 30%, affecting leaves and grains, impacting productivity and industrial quality.
Sheath blight, caused by Rhizoctonia solani, has gained attention in recent cycles, showing greater incidence in specific producing regions, including western Rio Grande do Sul frontier areas. The disease interferes with grain filling and reduces plant productive potential.
Climate-Disease Relationship Defines Management Strategies
The climate-disease relationship determines management strategy definitions. Regions with greater rainfall frequency, including the Santa Catarina coastal production areas, face elevated foliar disease pressures. In Tocantins, a more tropical climate with high temperatures associated with humidity, demands more intense management programs with greater fungicide application numbers throughout the cycle. In Rio Grande do Sul, beyond heat and humidity, frequent cloud cover acts as an additional risk element.
Preventive management assumes a central role, beginning with cultivar selection showing genetic resistance levels, especially to blast. Programs continue with seed treatment and preventive vegetative stage applications. The most critical period concentrates in the reproductive phase between floral differentiation and full flowering, when the absence of intervention significantly elevates economic loss risks.
Kilymos Combines Proven and Novel Active Ingredients
“The product was developed exclusively for rice cultivation, from formulation conception through agronomic positioning definition,” Scherer stated. “The fungicide combines two active ingredients with distinct action modes: tricyclazole, recognized for efficient blast control; and Revysol, BASF’s exclusive triazole, targeting broad-spectrum foliar spot control.”
Tricyclazole presents a consolidated blast management history with preventive and curative action, directly addressing the culture’s principal target. Revysol represents innovation within the triazole group, offering high efficiency against different spot-causing pathogens, plus physicochemical characteristics amplifying safety and flexible uses.
The combination confers differentiated positioning within management programs, acting on rice’s principal disease, while expanding brown spot and sheath blight control—a complete label for Brazilian rice cultivation.
Superior Foliar Absorption and Residual Activity
Among Kilymos technical differentiators, the elevated foliar absorption rate stands out. Internal studies indicate Revysol can present absorption significantly superior to other fungicides. After penetration, the active ingredient distributes and maintains storage in plant tissues, contributing to prolonged residual effects.
This characteristic confers greater product tolerance to climatic adversities. Post-application rainfall and intense heat periods exert lesser influence on control efficiency. The fungicide maintains elevated performance, even under adverse conditions common in irrigated rice-producing regions.
Another technical aspect involves Power Flex technology. The molecule presents structural flexibility, permitting better fit at the fungal action site. This characteristic amplifies active ingredient binding powers and hinders pathogen resistance development. Even facing mutations, the molecule maintains an action capacity, prolonging field technology useful life.
