Brazilian sugarcane producers now have one more alternative for the control of nematodes - one of the main "headaches" affecting this crop, which can generate losses of 25% in production. This is the Pontiac 350 SC, from the chemical group Methyl carbamate oxime, which makes it the first thiodicarb registered in the sugarcane market in Brazil.
Applied to the furrow of the plant, nematicide acts to reduce the infestation of major soil worms affecting this crop, such as Meloidogyne javanica and Pratylenchus zeae. According to the manufacturer, Rotam do Brasil, the product "increases the vigor of the cane field and, consequently, increases the index of the leaf area and the development of the tiller".
"The polymers of the product protect the molecule under various conditions of use. In addition, Pontiac 350SC is endowed with sunscreen in its formulation, which avoids photolysis, which is the decomposition of chemicals, through solar action. The components present in its formulation also provide excellent stability, homogenization and compatibility in the application mix and, thus, increase operational efficiency, "explained Carlos Guarnieri, senior technician at the Experimental Station, Arthur Nogueira-SP.
Data from a demonstration field research in the area of a supplier of sugarcane in the region of Piracicaba (São Paulo) revealed that the control produced 55 tillers every 10 meters, and the plant with the product, 76 tillers, that is, 38% more. Production also increased by 13%, with Pontiac 350 SC - 81.1 tons of sugarcane per hectare, compared to 70.5 tons of sugarcane. "The production with the application of nematicide was more than one ton of sugar per hectare. That is, more money in the producer's pocket," said Guarnieri.
In addition to more sugarcane, the product interferes directly with the promoter's hormones, mainly responsible for the development of roots and growth of the primary stem. It helps in anticipating the formation of roots, benefiting sprouting and thus increasing efficiency and resistance to different environmental conditions. This further growth, provided by the application of stimulant substances, such as the Pontiac 350 SC, is known as a phytotoxic effect.
