Pesticides seem to have a lot of bad reputation in our newly enlightened world.

This is why we have compiled a list of the best in organic pesticides to keep you enlightened as well as help anyone to look into potential farming and wanting to know the best in the business.

The concept and practice of utilizing microorganisms and other chemicals to control insect pests isn't a new idea. Pest control strategies in prehistoric times are mentioned in the writings of ancient Egyptian and Chinese scholars. Some scripts relate the practice of gardeners in several Egyptian pharaohs maintaining bacterial collections for use against insects that attacked and ravaged the gardens surrounding their houses and tomb chapels.

Some harmful pesticides are still used today, so this is why we have compiled some of the best in the organic field to help you be away of what you put in your body.

Organic Pest Spray

Pesticides are substances or chemicals that are used on plants and crops to keep away bugs and pests.

There are also different types of pesticides.

Some of the most common being glyphosate, which is usually used on
genetically modified soy, corn, canola, and cotton, as well as in home gardens and parks, atrazine, which is usually used on weeds, Chlorpyrifos, which is usually used in home gardens and is even known to give health benefits, Metolachlor, which is a herbicide, and Metan Sodium, which is a widely used fumigant that is usually put on potatoes.

2. Are They Harmful?

Organic pesticides usually elude both harmless and unaltered crops so that it serves its purpose without doing anything bad to your body.

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.

Final Thoughts

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.
