The Biostimulation Activity of Two Novel Benzothiadiazole Derivatives in the Tomato Cultivation
Biostimulants are gaining more and more attention in modern agriculture. As follows from the definition, their role is aimed at influencing the plant’s metabolism, which results in increasing the quantitative and qualitative parameters describing the yield. Significant attention should be paid to biostimulants increasing the content of health-promoting substances contained in plants. Treatments with biostimulants should be properly incorporated into existing plant protection schemes, which, of course, requires detailed research in this area. However, reliable research on active substances contained in biostimulants should be made first, and the activity of a given biostimulant must be proven. This work presents the results of a field experiment in tomato cultivation for two new active substances belonging to the group of benzothiadiazoles. The results indicate a positive effect on plant yield and, above all, on the lycopene content in tomato fruits. Increasing the lycopene content in fruit is of key significance, as it opens up opportunities for these active substances to be incorporated into new plant protection programs.
