How do you choose the correct absorption enhancer?

Author: Jan-Paul de Wit| Latest update: 10-03-2020

Absorption enhancers ensure that crop protection agents are better absorbed into the plant. This can lead to a strong improvement in efficacy. They are often additives based on vegetable oil or plant oil esters. These additives give a visible emulsion when you add them to water. There are also absorption enhancers that are naturally soluble in water. But how do you choose the correct absorption enhancer for your crop? In this article, our specialist explains. 

Absorption enhancers based on vegetable oil (including esters)

In some crops, these oily substances can cause a crop reaction that can lead to plant damage. Usually this is caused by too high an uptake of a highly active substance for the crop. The oil itself can sometimes even cause a reaction on sensitive tissue. In order to prevent this, sometimes it is preferable to use another type of absorption enhancer,on sensitive crops; for instance, polyglycol. 

Without previous exposure

If you want to apply an oil based adjuvant for absorption enhancement to a crop, always try this first on a small trial patch of crop. Thus, a possible crop reaction will not have a major impact on production. Also, be well informed about the use of absorption enhancers.
