“…The highest inhibitory activity was observed for both DC (MIC E1/E2 = 50/50 μg dry matter mL −1 , F. verticillioides , F. graminearum sensu stricto and F. subglutinans ; MIC E1/E2 = 25/25 μg dry matter mL −1 , F. proliferatum and F. meridionale ) and Vendaval thi‐carb fv (MIC E1/E2 = 100/100 μg dry matter mL −1 on all the Fusarium species, except for F. subglutinans ). The lignan NDGA was also assayed as reference of antifungal effect because it is the major antifungal principle found in the alcoholic extract of the creosote bush ( Larrea tridentata ) which is currently used as a botanical fungicide on vegetable crops (Vogt et al, ; Merino‐Ramos et al, ). NDGA showed the same antifungal activity or 2‐fold less inhibitory activity than DC and was 8–16‐ and 4–8‐fold more active than TZP and HF, respectively.…”

The ethanolic leaf extract (TZP) of Zuccagnia punctata, its ethereal fraction (Eet), 2 ′ ,4 ′ -dihydroxychalcone (DC), 2 ′ ,4 ′ -dihydroxy-3 ′ -methoxychalcone (DMC) and 7-hydroxy-3 ′ ,4 ′ -dimethoxyflavone (HF) were evaluated as fungicide seed protectants on corn. Microdilution assays on a set of Fusarium strains showed minimum inhibitory concentrations (MICs) of 400-800 g mL −1 (TZP), 50-100 g mL −1 (Eet), 25-50 g mL −1 (DC), 50-100 g mL −1 (DMC) and 200-400 g mL −1 (HF), with minimum fungicidal concentration (MFC)/MIC = 1. Suspensions of TZP, Eet, DC and DMC at MIC × 20 incorporated to the grains at rates of 1920, 240, 120 and 240 mg dry matter kg −1 of grain, respectively, increased the elongation of the primary roots (24-44%) and the number of seminal roots (44-50%). TZP also increased the number of secondary roots. HF was phytotoxic. Suspensions of TZP, Eet, DC and DMC suppressed the endogenous grain mycoflora at levels similar to those recorded for a thiram + carbendazim-based fungicide. Grains treated with TZP (1920 mg kg −1 ), Eet (240 mg kg −1 ), DC (120 mg kg −1 ) and DMC (240 mg kg −1 ) stimulated the growth of the seedling root system both because of fungal suppression and hormetic effects in greenhouse curative and preventive assays against Fusarium verticillioides on a sand/soil substrate. Eet and its chalcones also reduced the severity of seedling blight more than the thiram + carbendazim-based fungicide in preventive assays and led to the same disease severity observed for the fungicide treatment in the curative assays. Our results show that Eet and its chalcones not only were effective seed protectants against F. verticillioides and other seedborne fungi, but also improved the early performance of maize seedlings.

“…Results of the in vitro evaluation indicate that the chloroform extract was active against all the fungi tested, and F. graminearum and M. phaseolina were the most sensitive species. The n-hexane extract was inactive against the fungi tested and methanol extract inhibited M. phaseolina only (Vogt et al 2013).…”

“…Many studies have reported the fungitoxic activity of various plant extracts. For instance, Vogt et al (2012), while studying the effects of the extract of a medicinal plant from Argentina, Larrea divaricata, corroborated its empirical use in the treatment of some plant diseases and showed high rate of antifungal activity, making it a potential natural source for biological control. Fiori et al (2000) reported that the extracts from the leaves of 567 Evaluation of the fungitoxic… FERREIRA, T. P. S. et al Eucalyptus citriodora inhibited the mycelial growth of the pathogenic fungus Didymella bryoniae, while the plant extract of Achillea millefolium inhibited the germination of spores of the same fungus.…”
