Environmental Impacts: Organic vs Non-Organic Pesticides

The biggest difference between organic vs non-organic pesticide use is their environmental impact.

Ecological impact of non-organic pesticides

The globally-used Ivermectin, a non-organic substance orally given to animals that suffer from parasites, has severe side effects on other organisms. When excreted, the chemical bonds of the substance are still intact, and that results in the death of a large numbers of animals living off animal excrements, such as flies and beetles--sometimes even bees and butterflies.1

In contrast to conventional pesticides, synthetic organic-certified pesticides are highly selective, meaning they only target a specific pest—not multiple ones. How?

Are organic pesticides any different?

Scientists identify a unique enzyme in an organism and create a chemical substance that only hinders this one enzyme from working correctly and thus killing the organism, the chemicals might disturb the excitation transfer of the synapses–meaning, it causes severe damage to the nervous system or hampers the growth. For our environment, that means minimised impact compared to other pesticides! This fact has gotten a lot of attention over the past years, and rightly so. If you compare organic pesticides to that of the non-organic pesticides, you will already notice that the ecological casualties are much lower.

Biopesticides also should not have negative effects on native plants and, ideally, dissipate before coming in contact with the groundwater to hinder it from spreading to other areas.

All pesticides have active substances that take action against ‘pests’ or unwanted plants. And, all active substances that are being used in the EU for a plant protection product must be approved by the European Commission to make sure that they are safe before they reach the market in a product. Substances have to be safe for human and animal health and the environment. Biopesticides simply take it a huge step further in all of these points.
