For the microbial insecticides having a peroral mode of action (bacteria, viruses, and microsporidia), both phagostimulants and UV protectants can be used to increase efficacy and residual activity. Commercial adjuvants such as molasses. Coax and Gustol acted as phagostimulants and UV protectants to Bt (7, 11) (Table 2). The use of the pregelatinized cornstarch Mirasperse , mixed with powdered sugar as an additive, improved rainfastness and residual activity 12).

Caprylic acid is effective against bacteria and fungi, optimum pH range < 6. Due to its limited water solubility it may be insufficiently active to protect the water phase of emulsion systems against microbial proliferation. A main application field for caprylic acid is the incorporation into cheese wrappers as an antimicrobial active ingredient. Caprylic acid may also be used as a flavouring adiuvant (Doores, 1993). Worthy on note is that caprylic acid exhibits insecticidal activity, too.
