A sharp rise in air temperature at the end of March and the start of April to extreme values provokes fast reproduction of pests and the spread of diseases. Sharp temperature swings cause stress and change physiological processes in plants.
Therefore it is very important not to waste time and to apply all possible measures to fight pests and diseases, reduce the manifestation of stress and optimize nutrition for the intensive build-up of rapeseed vegetative mass.
At present a mass spread of the cabbage seed weevil is observed, which can significantly reduce the crop yield, so appropriate insecticides must be applied to protect the crops.
- At the stem elongation stage lateral shoots and generative organs are formed. Later the plants actively grow in height, so it is advisable to feed with critically needed elements.
To prevent stem cracking and to ensure the elasticity of cell walls, boron is especially important in the period of active growth. Therefore we recommend applying 1.0–1.5 l/ha ECOLINE Boron (Premium) to supply this element and to reduce stress with the L-α-amino acids contained in the fertilizer.
It will also be appropriate to add ECOLINE Phosphite (K) 1.0 l/ha to the tank mix to supply readily available phosphorus and potassium.
To stimulate root system growth and improve the work of fungicides. During intensive stem growth a complex of micronutrients ECOLINE Oilseed (Chelates) 1.5 l/ha will be needed. The fertilizer allows plants to be supplied with a wide range of elements: N, K, S, Mg, Mn, Zn, Fe, B, Cu.
