What are two examples of biological control products used in turf?

• A. Beauveria bassiana (insect-pathogenic fungus) and Bacillus thuringiensis (Bt) for caterpillars
• B. Nimot and Abamectin
• C. Glyphosate and 2,4-D
• D. Chlorpyrifos and Imidacloprid

Answer: (A)

Biological control products use living organisms or their products to suppress pests, offering a targeted, environmentally friendly option in turf IPM. Beauveria bassiana is an insect-pathogenic fungus that infects and kills a range of turf pests, while Bacillus thuringiensis (Bt) is a bacterium that produces toxins specific to caterpillars. Together they illustrate two common types of turf biocontrols: a fungal pathogen and a bacterial toxin producer, used to reduce insect damage with usually lower non-target impact. The other options mix herbicides or conventional insecticides, which are not biological control products. Nimot isn’t a recognized biocontrol agent; glyphosate and 2,4-D are herbicides; chlorpyrifos and imidacloprid are synthetic insecticides. Abamectin comes from a natural product but is generally classified as a chemical insecticide rather than a biocontrol product.
