Stem-shortening growth regulators inhibit the growth of grain stems, reducing the risk of crop lodging. We work to ensure that the use of chemicals in cultivation is sustainable, to minimize environmental and health-related risks.
Growth regulators are used to inhibit the growth of grain stems, reducing the risk of crop lodging which leads to difficulty harvesting and harvests of lower quality. In Sweden, stem-shortening growth regulators have previously only been allowed to use on rye, which has longer stems than other grain types. Legislation has been less restrictive in the rest of the EU. Since 2011, use of stem-shortening growth regulators on wheat, barley and oats is permitted in Sweden as well.
There is an ongoing discussion in the industry and in media about traces of pesticides in foods as well as other environmental and health aspects related to pesticides. When it comes to grain, the discussion is primarily focused on the use of stem-shortening growth regulators, since they are basically the only chemicals sometimes found in detectable levels. In Sweden the National Food Agency tests for traces of pesticides in vegetable and animal-based foods annually, to ensure they don’t contain amounts that are harmful or too high. These tests show measurable levels of growth regulators in certain cases, mainly in rye products. However, the levels are way below current limits for foods.
Lantmännen handles large amounts of grain and therefore needs to ensure clear standpoints and responsible handling with regards to growth regulators in different grain flows.
