| The Rare Earth Elements (REEs) is a group of 17 chemical elements, where 15 belong to the group of lanthanides, and the other two are scandium and yttrium. The largest mineral deposits of REEs are in China, which dominates over 95% of the world market. Research on crops with the use of compounds based on REEs – performed mostly in China – showed an increase in productivity, plant growth, disease control and other beneficial effects, usually when they are applied in low concentrations. The reasons for these effects are not sufficiently understood, but recently, physiological interactions with calcium, effects on the structure and function of the cytoplasmic membranes, changes in photosynthesis, hormone metabolism, enzyme activity, and increased... |

| Medicinal plants have active compounds in their composition produced from secondary metabolism, which can have fungistatic and /or fungitoxic action on the development of phytopathogens. The objective of this work was to study the effect of aqueous extracts of Ocimum basilicum, Baccharis trimera and Cnicus benedictus on mycelial growth of plant pathogens. The experimental design had three medicinal plants, six concentrations of each aqueous extract (1%, 5%, 10%, 15%, 20%, 25% and 50%), five fungus - Alternaria alternata, Colletotrichum graminicola, Phytophthora sp., Rhizoctonia solani and Sclerotinia rolfsii, and four repetitions for each treatment. The variables analyzed were: inhibition of mycelial growth, mycelial growth and area under the curve of... |

| Various methods are been used to control post-harvest diseases of tomato fruits. With the increasing restrictions on the use of fungicides, due the food safety and environmental impacts, the use of alternative methods and biological control of postharvest diseases have been stimulated. The aim of this work was to investigate the effect of alternative products in post-harvest treatment of tomato “Delta” and “Debora” produced under two cropping systems: intermediate (IS) and conventional system (CS). The components evaluated were the reduction of fresh mass, pH, soluble solids (SS), titratable acidity (TA) and the pathogens incidence after being treated by immersion with acibenzolar-S-methyl (ASM), Azadirachta indica crude extract, citric biomass extract and... |
