Managing winter rapeseed crops in September 2022
Winter rapeseed is a profitable crop, and therefore, despite certain difficulties in growing it, it does not lose its position in our country's farming. Autumn is a particularly responsible period because plants are preparing to lay down the yield components of the future harvest and for successful overwintering. On the way to these tasks there are several main problems: protecting plants from damage by pests and diseases, supplying boron and growth regulation.
Observations of rapeseed crops in early September showed that at this time there is a real danger of seedling damage by pests. Among the most dangerous are Lepidoptera (cutworms, diamondback moth, cabbage white butterfly, rapeseed sawfly) and Coleoptera (cruciferous flea beetles, bugs and the cabbage seed weevil, which colonizes crops in autumn but causes damage only in spring).
In our opinion, insecticide protection of winter rapeseed plants should be combined with foliar feeding with «ECOORGANIC» fertilizers. For the first feeding it is appropriate to apply ECOLINE Boron (Organic) at a dose of 0.5–1.0 l/ha to supply boron.
Given the sharp change in weather and the drop in temperature, to improve phosphorus nutrition, feeding the crops with ECOLINE Phosphite (K) 1.0 l/ha must be a mandatory measure. Such an agronomic practice will normalize the pH of the tank solution within 6.0–6.5, improve root system growth and provide a fungistatic effect for young rapeseed plants.
