Efficacy of biological products in an integrated pest and disease management system for tomato

Tomato (Solanum lycopersicum L.) is one of the most important vegetable crops; however, its productivity under open-field conditions is significantly constrained by a complex of fungal, bacterial, and viral diseases, as well as insect pests. The aim of this study was to develop and evaluate the effectiveness of an integrated tomato protection system based on the application of protective-stimulating formulations for seed treatment under the agroecological conditions of southeastern Kazakhstan. Laboratory experiments included seed phytosanitary assessment and evaluation of the effects of protective-stimulating formulations on seed sowing quality and contamination with phytopathogens. Under field conditions, the biological and agronomic efficacy of integrated protection schemes against the major tomato diseases and pests was investigated.The results demonstrated that tomato seeds represented a significant source of bacterial infection. Application of the protective-stimulating formulation PSF No. ۳ resulted in complete suppression of bacterial infection and a marked improvement in seed sowing quality. The integrated protection schemes effectively reduced the development of root rot and early blight (Alternaria spp.), with the highest yield obtained under protection scheme No. ۲. The findings confirm the high potential of an integrated tomato protection system based on biological methods as a sustainable alternative to conventional chemical control strategies.
