Brazil is the largest producer of sugarcane in the world, with almost 9 million hectares of planted area. The crop protection market generates around US $ 1.4 billion. Part of this value is in the use of pesticides to combat the sugarcane borer (diatraea saccharalis), one of the main challenges in Brazilian sugarcane fields.

The caterpillar has a direct effect on the quality of the raw material. Studies show that with only 1% of infestation in the cane field, damage to productivity can reach 35 kilos of sugar and 30 liters of ethanol per hectare. It is estimated that the pest is responsible for a loss of R $ 5 billion per year to the sector.

One of the biggest difficulties is to fight the pest before the egg hatches. A new crop protection product, Revolux, launched by Corteva Agriscience, promises to control the drill throughout the cycle, including ovicidal action. “We believe that we can contribute to the development of this market, bringing innovative solutions and facilitating the farmer’s daily life. Our expectation is to contribute to the sustainable growth of the sugar cane sector with the solutions that Corteva has in its portfolio ”, comments Mariana Castanho, commercial leader of sugarcane at Corteva.

The insecticide gathers new active ingredients in the market, such as spinetor and methoxyfenozide, which act with a differentiated mode of action for a prolonged protection of the cane against the drill. “There are two chemical groups that today do not exist within the culture and make it able to deliver a high efficiency in controlling the entire cycle of this main pest. It is a product that manages to control from the egg because it has an ovicidal action and brings speed to the control with a long residual, ”says Rodrigo Takagawa, leader of the sugarcane portfolio at Corteva.

The product is selective to natural enemies, allowing to rotate chemical and biological controls and expand the capacity of integrated pest management. “We know that using the same insecticide in the same culture ends up selecting resistant individuals in that chemical group, causing it to increase the frequency of this population of resistant insects and, consequently, the loss of insecticide. So Revolux is a tool
which brings speed of control and manages to reduce the initial population and with a low dose per hectare, from 100 to 200 milligrams, due to the high insecticidal power of this product ”, he points out.

It was ten years of research and the tests show that when observing an area with 8% infestation, in seven days after the first application of the product, the index was reduced to 1%. “Precisely because of the speed of control, linked to ovicidal action. With the long resistance and the long residual, this control continued for 60 days ”, he added.
