The bionematicide, Nematus, was launched in June and has an antibiotic and antimicrobial effect. Produced by Vectorcontrol and distributed by Santa Clara Agrociência, the biological pesticide is composed by Bacillus amyloliquefaciens, Bacillus licheniformis, and Bacillus subtilis.
According to agronomist Weber Agostinho da Silva from VectorControl, Nematus beneficially alters the root exudates. Therefore, the product “confuses” the nematodes, and ensures the pathogen does not end up finding the protected plant, explained the expert.
Besides the direct benefit of root protection, the company pointed out that Nematus has indirect benefits of favoring plant growth. This is because the product brings nutrients, vegetable growth hormones and amino acids, which induce the resistance of the vegetable to plagues and diseases.
Another indirect effect is the “biological correction of the soil” because of the higher availability of nutrients such as phosphorus through the solubilization of phosphates, silicates, and zinc. According to the maker, the bionematicide decomposes the essential organic material for the growth of the plant, regenerates exhausted soils, maximizes the absorption of chemical fertilizers and reduces water consumption for improving the absorption and soil retention.
The technical recommendation of the application is 200 mill per 100 kilos of seeds (inoculation), or soil application in the case of vegetables of 2 to 4 liters per hectare. Nematus can also be applied through the soil in perennial crops at the measure of 1 to 2 liters per hectare.
