What type of chemical composition is made up of oxygen and boron?

The type of chemical composition made up of oxygen and boron is borates. Borates are a group of chemical compounds that contain boron and oxygen, typically combined with other elements. They are commonly used in various applications, including pest control, due to their effectiveness against wood-destroying insects like termites. The reason borates are particularly useful in termite treatment is that they act as a stomach poison to insects when ingested, disrupting their ability to digest food.

In the context of pest control, borates are often used as a preventive measure in wood preservation, helping to safeguard structures from termites and other wood-boring pests. Their unique chemical makeup not only contributes to their insecticidal properties but also makes them effective in various environmental applications.

Other options like insecticides, herbicides, and fungicides do not specifically reference the combination of oxygen and boron in their chemical structure. Insecticides target insects, herbicides target unwanted plants, and fungicides target fungi, but none of these categories specifically involve the composition of boron and oxygen as borates do.
