Over the years, crop protection products have become increasingly specialized in order to target specific pests and weeds. Farmers also have to guard against resistance, which can occur if the same product is over-used. Therefore, a variety of crop protection products is available to control the same pests, weeds and diseases. As a result, a combination of crop protection products can be present in either the environment or as “multiple residues” in the food. Consumers are concerned about these combinations and want to know what this means for the environment and human health.
We include below some frequently asked questions that you may find interesting as well:
"Mixture toxicity" describes the effect that occurs when the toxicity of a combination of different chemicals is higher than the toxicity of each of the individual substances. However, this is not commonly the case.
"Mixture toxicity" occurs when chemicals have a common toxicity. In these cases, toxicity levels can add up or even - in very rare occasions - combine to have a so-called synergistic effect.
Crop protection products can only be approved when a comprehensive set of studies shows that they can be used safely for the farmer, the consumers and the environment.
Regulatory authorities carefully evaluate such studies before they approve a product to be marketed.
As part of the standard pesticide assessment, mixture toxicity is evaluated in our crop protection products that contain more than one active ingredient.
