Beauveria bassiana is an entomopathogenic fungus that causes white muscadine disease in a range of insects including whiteflies, aphids, thrips, grasshoppers and certain types of beetles. Once the host insect is infected, the fungus rapidly grows inside of the insect, feeding on the nutrients present in the host's body and producing toxins in the process. When the host dies, the B. bassiana covers the carcass in a layer of white mold that produces more infective spores.

What pesticide you may use in your garden will totally vary on who you are as a person where you are located, and the threats you may encounter. Each pesticide distinctly carries little cons through scientific and natural means, but there are always methods to find out more about what type of insects may invade your specific garden, and what pesticide would best suit your needs for that.
It would be nearly impossible to determine which is the best without knowing what the potential threat could be to your crops. Overall, organic pesticides are important to consider when having a garden, and anything that can make your crops grow with no troubles is always the most rewarding, so research what goes into your food, and make your own decision on what would be best to pick up or garden with.
