Rootshopper, increasingly dangerous insect for sugarcane plantations

The presence of sucking insects, such as the root leafhopper, has increased in sugarcane fields, demanding more attention from Brazilian farmers and causing significant damage. Proof of this is that, in 2022, pesticide applications against this pest increased, according to the National Union of Plant Defense Products Industry (Sindiveg).

Mahanarva fimbriolata, the scientific name of this insect measuring only 12 millimeters, feeds on the sap present in the roots of sugarcane, which impairs the absorption of water and nutrients essential for the health of the plant and – consequently – its good development. of culture, historically one of the most important in agribusiness in Brazil.

Feeding the leafhopper can also cause the cane roots to rot and die. Estimates indicate that the pest has the potential to lose up to 80% of the crop if not treated properly.

Based on data from the National Supply Company (Conab), which estimated the national production of sugarcane in the 2021/2022 harvest at more than 585 million tons, the financial impact of the pest could reach R$ 48.6 billion – remembering that the Basic Value of Sugarcane Production estimated for 2022 is R$ 95 billion.

These numbers show the urgency of effectively combating Mahanarva fimbriolata. Acetamiprid and bifenthrin are molecules developed and with effectiveness already proven by science that have contributed to the decimation of the root spittlebug. Together, they represent the best insect control strategy, with prolonged action and protection of the cane fields.

Acetamiprid, a neonicotinoid, is celebrating 50 years of excellent results in the field. This active ingredient acts directly on the leafhopper's nervous system, as does bifenthrin. The association of these insecticidal functions enhances the control of the pest, causing its death and minimizing the negative effects on sugarcane.

This union of active ingredients stops the damage immediately. With this management option, it is possible to increase sugarcane production safely and sustainably, benefiting food production, such as sugar, and the alcohol, energy and biomass market, in addition to the Brazilian economy as a whole. It is science at the service of productivity in the field.
