“…These studies also provide valuable information for future evaluations of the application of plant extracts in the field [ 7 , 70 , 71 ]. In this study, B. subtilis and T. asperellum were selected for their history of promoting plant growth, other benefits, and their biological plasticity [ 72 , 73 ]. No symptoms of toxicity were apparent on tomato leaves or the beneficial organisms evaluated after treatment with the 12% ( w / v ) aqueous extract of C. chichenensis roots, which is compatible for its possible combination and application with the biocontrol agents Trichoderma and Bacillus [ 74 , 75 ].…”

Plant extracts are a valuable alternative to control pathogens of horticultural crops. In the present study, four species of pathogenic fungi were isolated from leaf spots on Solanum lycopersicum and identified by traditional and molecular techniques as Alternaria alternata ITC24, Corynespora cassiicola ITC23, Curvularia lunata ITC22, and Fusarium equiseti ITC32. When 11 aqueous extracts from eight native plants of the Yucatan Peninsula were tested against the four fungi in vitro, the extract from Croton chichenensis roots was most active, inhibiting mycelial growth (79–100%), sporulation (100%), and conidial germination (71–100%) at 3% (w/v). A logarithmic–diagrammatic scale of the pathosystem C. cassiicola–S. lycopersicum was established and used to assess disease severity on inoculated tomato plants in a greenhouse after treatment with the aqueous extract from C. chichenensis roots at 12% (w/v). After 21 days, the disease severity was 57% lower than on the control without extract applied. This dose of the extract was not phytotoxic to tomato leaves and was compatible with the beneficial organisms Bacillus subtilis CBCK47 and Trichodema asperellum Ta13-17. The antifungal efficacy of C. chichenensis is highly promising for incorporation into integrated disease management of tomato crops.

“…All treatments were arranged in a completely randomized design. The data of percent inhibition of mycelial growth were transformed with the arcsine: √ percent inhibition/100 [ 25 ]. Analysis of variance ( p ≤ 0.05) and Tukey’s test ( p ≤ 0.05) were performed using the SAS statistical package (V. 9.0., SAS Inst.…”

Three pathogenic fungi of blueberry (Vaccinium spp.) responsible for dieback disease, identified as Pestalotiopsis clavispora, Colletotrichum gloeosporioides and Lasiodiplodia pseudotheobromae, were isolated in the northwestern region of the state of Michoacán, Mexico. The mycelial growth in vitro of these fungi was inhibited by extracts from Lantana hirta, Argemone ochroleuca and Adenophyllum porophyllum, medicinal plants collected in Sahuayo, Michoacán, Mexico. The extracts showed different degrees of inhibition; the most effective were: M5L extract from L. hirta and M6LFr extract from A. ochroleuca, both of which inhibited 100% of the mycelial growth of P. clavispora and C. gloeosporioides; and M4LS extract from A. porophyllum, which inhibited 100% of the mycelial growth of the three pathogens. The extracts were fractionated by thin layer and column chromatography, and the most active fractions were analyzed by gas chromatography-mass spectrometry. The major compounds identified in L. hirta extract were Phytol and α-Sitosterol. The compounds identified in A. ochroleuca were Toluene and Benzene, 1,3-bis(3-phenoxyphenoxy)-. In A. porophyllum, the compound identified was Hexanedioic acid, bis(2-ethylhexyl) ester. These results show the potential of L. hirta, A. ochroleuca and A. porophyllum as a source of antifungal compounds.

El trabajo de investigación se realizó en el laboratorio de la Universidad Nacional Agraria La Molina, Perú, como una alternativa al control químico se efectuaron ensayos In vitro para determinar el efecto de los microorganismos Trichoderma harzianum (T), Bacillus subtilis (B) y fertilizante proteinato de cobre (P) para el control de Lasiodioplodia theobromae y Fusarium verticillioides asociados a semillas de palto. Técnicas de cultivos duales, triples y cuádruples se realizaron en medio papa dextrosa agar entre los patógenos y tratamientos (T, B, P, T+B, T+P, B+P y T+B+P) bajo un diseño completo al azar con arreglo factorial de 2 (patógenos) x 7 (tratamientos) con cuatro repeticiones. Todos los tratamientos tuvieron efecto en el control de ambos patógenos con valores de inhibición micelial mayor del 60%. La interacción entre T. harzianum + Proteinato de cobre fue el tratamiento con mayor efecto en la inhibición micelial de los patógenos con 91.23 % seguido del fertilizante proteinato de cobre con 87.67 % y T. harzianum con 81.84 % de inhibición, en comparación a Bacillus subtilis. que tuvo menor efecto en el control de estos patógenos fungosos.
