Improper or excessive use of fertilizers can even contaminate the aquifer through the phenomenon of leaching, so the optimal alternative for agriculture is the use of foliar fertilizers. The agricultural sector must not be a source of environmental pollution, which is why we need innovative products with low toxicity that are environmentally friendly. The objective of this paper was to test an ASFAC BCO-4 biostimulator, MESSIS BOR fertilizer and EFUSIO adjuvant on 3 tomato varieties: Crystal, Oxheart, and Bacuni. The results showed that in all the variants tested, the products used did not have a significant impact on the size of the leaf mass, but had an impact on the inflorescences in all cases analyzed.
