Windsar 250 EC is a universal regulator for plant growth and development in agricultural cultivation and is offered as a concentrate for preparing a water emulsion. The product can be used in winter and summer wheat, summer barley, as well as other cereals and special crops. The active ingredient is characterized by a wide BBCH application range and a long application period. Windsar 250 EC supports root system development, increases yields, facilitates harvesting, and prevents lodging of the crop. It contains Trinexapac-Ethyl at a concentration of 250 g/l. The product acts systemically and is quickly absorbed through leaves and stems, strengthening and shortening the stems without negatively affecting the plant mass. Optimal application conditions are temperatures of 10–15°C with intense sunlight. ☀️🌾

⚙️ How does Windsar 250 EC work? ⚙️
Windsar 250 EC acts systemically. After application, the product is absorbed very quickly mainly through leaves and stems and then transported to the meristematic tissues. It prevents excessive elongation of the internodes. Neither plant mass nor root length is reduced. The shortening and stiffening of cereal stems prevents lodging of the crop stand. 🌾
The intensity of the effect depends on the developmental stage of the crop, the variety, the location, and weather conditions. The internodes that stretch intensively during the application period are shortened the most. Genetically tall varieties respond with a stronger shortening of the internodes.
The product prevents lodging of plants in intensive cultivation systems with high nitrogen fertilization. 🌱
