Usage

Uses

Fluorescent (optical) brighteners are known for their characteristics of protecting baculoviruses against deactivation by UV light and enhancing the activity of these agents as microbial insecticides on hosts and semipermissive hosts. Fluorescent brighteners improve the bioinsecticidal activity of Anticarsia gemmatalis nucleopolyhedrovirus.
