Which of the Following is a Microbial Product Used to Reduce

Question

Which of the following is a microbial product used to reduce crop damage?
A) Bt toxin
B) saxitoxin
C) ice-minus
D) both Bt toxin and ice-minus
E) both Bt toxin and saxitoxin

Accepted Answer

Bt toxin and ice-minus are both microbial products used in agriculture. Bt toxin, derived from Bacillus thuringiensis, is used as a biopesticide to control insect pests. Ice-minus is a genetically modified bacterium used to inhibit the formation of ice on plants, reducing frost damage. Saxitoxin, on the other hand, is a neurotoxin produced by certain species of marine dinoflagellates and is not used to reduce crop damage.
