Bio-guided isolation of aromatic abietane diterpenoids from Salvia canariensis as biopesticides in the control of phytopathogenic fungi.

Background: Biofungicides arise as a promising alternative to the indiscriminate use of harmful synthetic fungicides in crop management.

Results: The present study reports the bio-guided fractionation of an endemic plant from the Canary Islands, Salvia canariensis against the phytopathogens, Alternaria alternata, Botrytis cinerea, and Fusarium oxysporum. This procedure allowed identifying a series of diterpenoids with an abietane skeleton (1-5), which exhibited remarkable activity against the phytopathogenic fungi assayed.

Antifungal Potential of Canarian Plant Extracts against High-Risk Phytopathogens.

Phytopathogens are responsible for great losses in agriculture. In particular, Fusarium, Alternaria and Botrytis are fungal diseases that affect crops worldwide. In the search for eco-friendly solutions to pest control, plants and their chemo-biodiversity are promising sources of biopesticides for integrated pest management.

Fungi as Endophytes in : Juxtaposed Elements of Diversity and Phylogeny.

is a plant genus highly studied for its medicinal applications. The studies on the associated fungal endophytes are scarce. Ten plants specimens of from Tenerife and La Palma were sampled to isolate the endophytic fungi.
