When crop productivity drops, with visible flaws in the development of plants, causing large “bounces”, the farmer soon imagines that it was caused by nematodes, a pest with a serious history in Brazil. However, a new torment may be added to the soybean production chain: Scutigerella immaculata. This insect, which attacks silently, causes serious damage to plant roots and, consequently, to the producer's profitability.

“A Scutigerella It is a centipede with an underground habit. It is whitish in color and can move vertically to deeper layers of the soil, depending on temperature and humidity. The presence of this pest is not widespread and everything indicates that it is present in several regions of the country”, explains Suellen Drumond, Seed Treatment Manager at Sumitomo Chemical.

The arthropod measures 2 mm to 10 mm, has agile movements and easily passes through cracks and soil galleries, migrating up to one meter deep.

According to Drumond, one of the most visible problems in crops is the reduction in the density of soybean crops, with slow vegetation development, causing large disturbances in the field and, thus, reduced productivity. This happens due to attacks on plant roots.

How to identify the pest in your crop

The incidence of Scutigerella is still not widespread, so it is not on the Brazilian farmer's radar. Therefore, it is essential to carry out identification tests in all agricultural regions of the country.

Sumitomo Chemical's Market Development agronomist, Isaias Bertanha, highlights that the test is simple and can be carried out by the farmer himself. “Make an opening in the soil, with your hand or a shovel, of 10 cm to 20 cm or until you find moisture. After that, take a potato and cut it in half, placing it at the bottom of the opening, with the cut surface of the potato in the soil,” he explains.

Then, reinforce Bertanha, cover the potato with soil and demarcate the area. After two to three days, check the baits to confirm the presence of the centipede. In soils with high humidity, see within two days, before the potato rots. It is worth using a dark surface, for example, a black canvas, for better identification.
