“…Trichoderma fungus is considered a free-living soil microorganism, which survives in tropical and temperate regions, being three species (T. harzianum, T. virens and T. viride) the most used in biological control of diseases and on growth promotion of several crops (Hoffmann et al, 2015). Many studies point out the use of Trichoderma to promote initial growth of many commercial crops, such as tomatoes and beans (Chacón et al, 2007;Guimarães et al, 2014), as well as an increase in grain yield and leaf crops (Azevedo Filho et al, 2011;Carvalho et al, 2015a).…”

The aim of this study was to evaluate four strains of Trichoderma spp. (T. harzianum IBLF 006 WP, T. harzianum IBLF 006 SC, T. harzianum ESALQ 1306 and T. asperellum URM 5911) for seedling growth promotion in laboratory and head lettuce yield in field conditions. The experiment was carried out in a completely randomized design with four treatments (strains): IBLF 006 WP, IBLF 006 SC, ESALQ 1306 and URM 5911 and a non-inoculated (without Trichoderma) control. Each treatment consisted of 200 seeds, arranged in four replicates. Lettuce seeds cv. Astra were treated with 2 mL Trichoderma suspension (2.5 x 108 conidia mL-1 per each 100 g seeds) and submitted to growth assay in laboratory up to 7 days after sowing. For field experiment, we opened furrows, which were manually sprayed with 5 x 107 conidia mL-1. Afterwards, seedlings were transplanted (4 to 6 leaves of head lettuce cv. Mauren) and harvested 40 days later. Each treatment consisted of four replicates (1.2 x 1.2 m, 16 plants per plot) arranged in randomized blocks. In both experiments, a control without Trichoderma application was included, and we evaluated shoot length, root and total length, shoot, root and total fresh mass and shoot, root and total dry mass, shoot mass ratio, root mass ratio and shoot/root ratio. The germination (%) was evaluated by laboratory tests, whereas in field experiment, height, stem diameter, head diameter, number of leaves and yield were evaluated. The T. harzianum strain ESALQ 1306 provided the best head lettuce growth rate in laboratory test, which was confirmed in field experiment, in which the productivity (50.2 t ha-1) was superior when compared to the other strains (41.38 to 44.23 t ha-1) and the control (30.18 t ha-1).

Essential oils are secondary metabolites whose biological properties have been studied with emphasis on antimicrobial activity. Hyptis carpinifolia Benth (Rosmaninho) is used in folk medicine in the fight against colds and rheumatism. The objective of this study was to evaluate the antimicrobial activity of the essential oil from H. carpinifolia. The essential oil was extracted by hydrodistillation using a modified Clevenger apparatus. The biological activity was determined using the Agar Cavity Diffusion technique to evaluate the effect of concentrations of 500, 250, 125, 62.5, 31.25, 15.62, 7.81 and 3.9

“…These values were higher than those found by Fantinel et al (2018), who evaluated the antagonistic potential of different isolates of Trichoderma and Baciulus thuringiensis against Colletotrichum siamense and found maximum MGIP of 32 % and 44.2 % on the 6 th and 12 th days, respectively. Hoffmann et al (2015) found that 3 of the 15 evaluated isolates had MGIP of 38.8 %, 44.4 %, and 48.9 % on the 7 th day of pairing, and 12 isolates showed high antagonistic potential, completely inhibiting the development of Fusarium sp., with growth inhibition percentages between 81.2 % and 94.4 %.…”

Tomato crops have great economic importance in Brazil and worldwide; however, its economic return is dependent on the control of several diseases, including Fusarium wilt, caused by Fusarium oxysporum f. sp. lycopersici. The control of this disease is usually based on biological products, which are commonly manufactured with antagonist isolates of Trichoderma sp. Therefore, the antagonistic potential of Trichoderma sp. should be better studied against other phytopathogens, thus expanding the biofungicide options on the market. The objective of the present work was to evaluate the antagonistic potential of different isolates of Trichoderma against the in vitro mycelial growth of F. oxysporum f. sp. lycopersici. Four isolates of Trichoderma spp. were tested, three collected in litterfall and one commercial isolate (T. asperellum). The Trichoderma spp. isolates were evaluated for antagonistic potential against F. oxysporum f. sp. lycopersici using the culture pairing technique. The variables evaluated were: mean colony size (MCS), mycelial growth inhibition percentage (MGIP), mycelial growth rate index (MGRI) of phytopathogen, and antagonism of isolates of Trichoderma spp. through a scale of grades. All isolates of Trichoderma spp. tested reduced the in vitro mycelial growth of F. oxysporum f. sp. lycopersici.
