FEEDING WINTER RAPESEED CROPS AT THE START OF FLOWERING
This spring's weather is not very favorable for growing winter crops. As a result of a cold, prolonged period, winter rapeseed plants in most regions are under stress, which may adversely affect the size of the future yield.
High prices for nitrogen fertilizers have forced producers to reduce nitrogen doses, which is already showing negatively on some areas. In particular, because of a lack of nitrogen and often of moisture, plants lag in growth and show visual signs of nitrogen shortage in the form of paler, deformed leaves. The stems show cracking of the epidermis, which will let disease agents such as gray mold and phoma into the plants.
As temperatures rise, pests will become more active, so insecticides and fungicides will have to be used to preserve the yield.
What does ECOORGANIC recommend in this period? Based on the conditions that have developed and on the results of successful long-term trials in our partners' fields, we recommend not forgetting to strengthen plant nutrition with boron and with phosphorus in the form of phosphite at the same time as applying crop protection products. The optimal combination is ECOLINE Boron (Organic) or ECOLINE Boron (Premium) 0.5 l/ha + ECOLINE Phosphite (K) 1.0 l/ha.
