Also in cereals Crop Fuel® has been thoroughly tested. On cereals, Crop Fuel® is sprayed 3 – 4 times at a rate of 2.5 L/ha during the growing season. Cereals such as winter wheat have an average yield increase of 1000 kg/ha. When the Crop Fuel® is sprayed early, the plant produces more stems and heads. Crop Fuel® also increases the number of kernels.
