Abstract
spp., RKN) penetrate the roots of plants, blocking the flow of water and nutrients, preventing plant development, and causing losses of up to 68% in production. Its management is limited by the low availability of genetically resistant materials, the inefficient use of biological controllers, and the high risk of environmental contamination from the application of pesticides. The aim of this study was to contribute to the integrated management of (RKN) through the use of chitosan. A completely randomized experimental design was used in a factorial arrangement with two applications (foliar or edaphic), two cherry tomato genotypes (IAC1687 and LA2076), and eight treatments (three concentrations of chitosan (1.5-2.0-2.5 mg/mL), commercial controls and absolute controls). The yield and nematode population components were evaluated. The cherry tomato (IAC1687) obtained the greatest yield, with 33.517.1 kg/ha and an 85% reduction in the nematode population with the application of 2.5 mg/mL of chitosan to the soil. Chitosan improved the yield components of the evaluated cultivars and reduced nematode populations, suggesting that it can be a sustainable alternative in commercial production systems, as it can help reduce the use of chemical pesticides and improve health and crop productivity. As a limitation of this study, the use of acetic acid as a solvent for chitosan potentially interfered with the results associated with the nematode population, increasing bias and imprecision as there was no blockage due to light, temperature, or irrigation. Therefore, we suggest that future research explores alternative solvents to elucidate the mechanism of action or response of chitosan.
