“…Previously, this activity was reported for Heliotropium floridum (Reyna et al, 1997), Cordia curassavica (Hernández et al, 2007), Ipomoea batatas (Stange et al, 2001) and I. carnea , whose latex possesses a quitinase (Patel et al, 2010). Whereas, examples of plants belonging to Euphorbiaceae (Niño et al, 2012; Ascacio-Valdés et al, 2013), Asteraceae and Verbenaceae (Hernández et al, 2008; Díaz-Dellavalle et al, 2011; Pupo-Blanco et al, 2011) with toxic activity on phytopathogens fungi are more common, particularly those from the Asteraceae family (Gamboa-Angulo et al, 2008; Nogueira et al, 2010; Carvalho et al, 2011). …”

The antimicrobial activity of 12 plant extracts was tested against the phytopathogens Alternaria alternata and Fusarium solani. In addition, the compatibility of the extracts toward Bacillus liqueniformis, a biofertilizer and a non-target microorganism, was assessed. Plants tested belong to the Euphorbiaceae, Asteraceae, Crassulaceae, Rubiaceae, Convolvulaceae, Verbenaceae, Orchidaceae, Nyctaginaceae, Boraginaceae, and Tiliaceae families and were collected in the State of Oaxaca. The antifungal activity of the plant extracts (50–100 mg/mL) against A. alternata and F. solani, was determined by measuring the mycelium radial growth and obtaining the minimum inhibitory concentration (MIC) of fungal growth. In addition, with the aim of finding plant extracts which are compatible with a B. licheniformis biofertilizer strain and to test the non-toxic nature of the treatments, the toxicity of the extracts toward this strain was evaluated using the agar diffusion method. Azoxystrobin (12 μg) and chloramphenicol (30 μg) were used as positive controls for the pathogens and for the non-target bacteria, respectively. Plant extracts inhibited fungal growth in the ranges of 0.76–56.17% against F. solani and 2.02–69.07% against A. alternata. The extracts of Acalypha subviscida, Ipomoea murucoides, Tournefortia densiflora and Lantana achyranthifolia showed MIC values between 5.77–12.5 mg/mL for at least one of the fungal species. The best treatment, Adenophyllum aurantium, exhibited a maximum inhibition for both F. solani (56.17%, MIC = 7.78 mg/mL) and A. alternata (68.64% MIC = 7.78 mg/mL), and resulted innocuous toward B. licheniformis. Therefore, this plant has an outstanding potential for the agroecological control of fungal phytopathogens in industrial crops.

Various pathogenic microorganisms affect plants. However, most diseases are caused by fungi, which have an enormous reproductive capacity and possess metabolic mechanisms capable to develop resistance to commercial fungicides. Fungi produce mycotoxins on crops and this represents a considerable risk to human and animal health. The most important genera of phytopathogenic fungi of the American continent are: Aspergillus, Alternaria, Botrytis, Colletotrichum, Fusarium, Phytophthora, Penicillium and Pythium, among others. Different strategies have been used for phytopatogenic fungi control, mainly by using synthetic fungicides. Currently, a great deal of attention has been paid towards exploitation of higher plant products as an innovative alternative in crops protection. The use of plant derived natural products has many advantages, such as little or no harmful side effects, rare cases of resistance, long-term control and completely or substantially eliminates the use of synthetic fungicides. Several plants belonging to the Anacardiaceae, Asteraceae, Caprifoliaceae, Lamiaceae, Liliaceae, Papilionacea, Poaceae, Verbenaceae, families, have showed fungicide potential. Therefore, this review addresses occurrence of the most important phytopatogenic fungi and the current state of research regarding the potential of vegetable biodiversity in the development of plant derived natural products for the management of these pathogens in the American continent.
