Foliar feeding of winter cereals at the start of heading
Flag leaf formation to the start of heading is one of the most important stages in forming cereal yield. In effect, it is the period for protecting crop quality. Weather conditions at this time are favorable for the development of leaf diseases and for pests that feed on plant sap.
Leaves damaged by pests and diseases cope worse with their main task: assimilating carbon in photosynthesis and forming reserve substances, which in turn lowers yield potential. Therefore it is important to ensure maximum photosynthetic productivity by protecting the upper leaves and especially the flag leaf from diseases and pest damage. And creating conditions for balanced plant nutrition with macro- and microelements will be an additional factor in raising yield and improving its quality indicators.
According to the results of our many years of field trials in different natural and climatic conditions of Ukraine, the most effective foliar feeding scheme for winter cereals at the flag leaf formation to start of heading stage is a combination in a tank mixture of a microelement complex with phosphorus in the form of phosphite: ECOLINE Cereal (Chelates) 1.0–1.5 l/ha + ECOLINE Phosphite (K) 1.0 l/ha.
