A method for controlling conidial germination and mycelial growth in fungi comprising contacting a fungal cell with anti-fungal small molecules in an amount effective to reduce or inhibit conidial germination and mycelial growth. A method for controlling bark beetle infestations of pine trees comprising contacting one or more fungal cells with anti-fungal small molecules in an amount effective to reduce or inhibit conidial germination and mycelial growth. The anti-fungal small molecules are 5-(p-Bromobenzylidine)-&#x3b1;-isopropyl-4-oxo-2-thioxo-3-thiozolidineacetic acid, 2-[5-(4-chlorobenzylidene)-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]-3-methylbutanoic acid, 2-[5-(4-hydroxybenzylidene)-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]pentanoic acid, [5-(4-isopropylbenzylidene)-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]acetic acid or 2-[5-(2-chlorobenzylidene)-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]pentanoic acid. The species of the fungal cell is selected from a group that has an obligate symbiosis with the mountain pine beetle () and the western pine beetle ().

Method for inhibiting conidial germination and mycelial growth of fungi symbiotically associated with bark beetles

A method for controlling conidial germination and mycelial growth in fungi comprising contacting a fungal cell with an anti-fungal small molecule in an amount effective to reduce or inhibit conidial germination and mycelial growth. A method for controlling bark beetle infestations of pine trees comprising contacting one or more fungal cells with an anti-fungal small molecule in an amount effective to reduce or inhibit conidial germination and mycelial growth. The anti-fungal small molecule is 5-(p-Bromobenzylidine)-&#x3b1;-isopropyl-4-oxo-2-thioxo-3-thiozolidineacetic acid. The species of the fungal cell is selected from a group that has an obligate symbiosis with the mountain pine beetle () and the western pine beetle ().

A method for controlling yeast-to-filamentous growth transition in fungi comprising contacting a fungal cell with an anti-fungal small molecule in an amount effective to reduce or inhibit the yeast-to-filamentous growth transition, wherein the anti-fungal small molecule is 5-(p-Bromobenzylidine)-&#x3b1;-isopropyl-4-oxo-2-thioxo-3-thiozolidineacetic acid or an analog thereof. A method for treating fungal infections comprising contacting one or more fungal cells with an anti-fungal small molecule in an amount effective to control the fungal infection, wherein the anti-fungal small molecule is 5-(p-Bromobenzylidine)-&#x3b1;-isopropyl-4-oxo-2-thioxo-3-thiozolidineactic acid or an analog thereof.
