Question: 1 / 400

Which chemical is known to be highly toxic to insects and decay fungi?

Sodium

Boron

Boron is recognized for its effectiveness as a pesticide due to its high toxicity to a range of insects and decay fungi. It works by disrupting the metabolic processes of these organisms, ultimately leading to their death. Boron compounds are frequently used in wood preservation because they not only protect against insect infestations but also combat the growth of decay fungi that can compromise the integrity of wooden structures.

This makes boron a popular choice in residential applications where environmentally friendly and less hazardous solutions are preferred for managing wood-destroying organisms. Its low toxicity towards humans and pets, combined with its potent effectiveness against pests, positions it as a favored chemical in home inspections and pest management.

Other chemicals listed may have various applications but do not possess the same level of specificity or effectiveness against insects and decay fungi as boron does.
