Bumblebees and pesticides

Pesticides or chemical crop protection and bumblebees do not always go hand in hand. Chemical crop protection products can have a negative impact on the bumblebee population or even kill it completely. That is why it is important to be well informed about the influence of chemical crop protection on the biology present within the crop.

Non-selective and selective agents

Pesticides and bumblebeesThere are many different types of pesticides. Some of them are non-selective all killing agents; others are selective. The non-selective killing agents not only kill the pest to be controlled, but also eliminate the bumblebees present in the crop. In contrast, selective agents only kill the pest and are not harmful to bumblebees. If, despite the use of biology, you still have to make use of pesticides, then take the following points into account:
  • Selective pesticides have little or no negative effect on bumblebees. If possible, choose a selective pesticide. 
  • If the use of selective pesticides is not possible, choose a selective application (e.g. pouring or dripping) and a crop protection product with a short after-effect. Our crop protection specialists can advise you on this. 
  • Bumblebees can be temporarily removed from the crop when you start using chemical crop protection. Place the bumblebee hives in a room of 18 - 20 degrees Celsius for a maximum of 2 - 3 days (a longer period will cause a shortage of pollen, which will have a negative influence on the bumblebee colony).
  • Before using chemical crop protection, also check how long a pesticide is harmful to the biology of your crop. Many pesticides can have negative effects on bumblebees for a (long) time after they have been applied. How long a pesticide is harmful is stated on the label. If there is nothing on the label, the side effects are unknown.

Insight into side-effects of chemical crop protection products

It is important that you have insight into the side effects of a pesticide before you apply it in the crop. But how do you know what kind of product you are dealing with and what the possible side effects of this product are? This information can be found on the label of the chemical crop protection product, but you can also easily find this information via the Agrobío Effects app, which is available on Android. The app offers the possibility to search by active ingredient, trade name, crop or product type, after which you will see the side effects of the product.
