This is an oversimplification. It is true that organic farmers are permitted to use certain chemicals on their crops, but the allowed substances are very different in terms of ecological impact compared to conventional chemical treatments (conventional chemicals and their breakdown products generally persist in the environment much longer).
Organic farmers are also required to try to manage pests without chemicals first, steering the organic industry towards “integrated pest management” where very small amounts of pesticides are used in a highly targeted manner.
Here is an excerpt from another source summarizing the requirement for integrated pest management:
"These plans address three levels of pest management. Level A is based on the expectation that a well-designed and healthy organic system will naturally have fewer pest problems. It focuses on pest and disease outbreak prevention practices such as cover crops, crop rotation and providing habitat for ladybugs and other beneficial insects.
If Level A practices are not sufficient, Level B focuses on the introduction of insect predators and parasites, mulching, grazing, mowing, solarization and other mechanical and physical practices.
If additional pest management is needed, Level C includes the use of natural and synthetic pesticides on the National List."

I don’t see anything backing up your alternative insect control claims, but it really is just a different batch of pesticides on wide use.

Also, the list you have linked is so so much less bad than the list of allowed chemicals for conventional farmers, which I can’t even find online… Best way I have found to view it is here: https://ordspub.epa.gov/ords/pesticides/f?p=CHEMICALSEARCH%3A46::::
Bottom line is that conventional pesticide use is much less transparent and less tightly regulated.
