The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient. The AI is usually formulated with other materials (adjuvents and co-formulants) and this is the product as sold, but ...

Its use in the control of malaria-transmitting mosquitos is under investigation. [2] As an insecticide, the spores are sprayed on affected crops as an emulsified suspension or wettable powder or applied to mosquito nets as a mosquito control agent. As a species, B. bassiana parasitizes a very wide range of arthropod hosts.
Bacillus thuringiensis (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide.

They are substantially more resistant to degradation by light and air, thus making them suitable for use in agriculture, but they have significantly higher mammalian toxicities. Over the subsequent decades these derivatives were followed with other proprietary compounds such as fenvalerate , lambda-cyhalothrin and beta- cyfluthrin .
