Description
The experience of the past years shows that even with the proper application of C-complex plant conditioner, all dangerous fungal pests of sugar beet can be effectively controlled. The damage caused by physiological diseases is significantly reduced, while at the same time sugar yields can be increased by using smaller amounts of fertiliser. To disinfect sugar beet soil, accelerate initial development and promote root formation, we recommend applying 10 l/ha as a starter using a liquid soil disinfectant adapter. May be applied in combination with insecticidal soil disinfectants. The first foliar application is recommended from the time of first disease onset, mid-June. The choice of the appropriate time should take into account the actual risk of infestation and the fact that the active substances of the product are both contact and adsorbent from a plant protection point of view. However, for plant nutrition reasons, it is advisable to approach the stage of full leaf cover. The recommended dosage is 10 l/ha depending on nutrient availability and vulnerability. Taking into account the nutrient requirements of sugar beet, it is recommended to add 4-6 kg/ha N active ingredient to the spray. A second spray is recommended from mid-July onwards, also at 10 l/ha, in case of irrigated production or rainy weather. In case of wet weather or irrigation, no N supplementation is necessary, but in case of drought (dry cultivation), a dose of 5-10 kg N/ha is also effective in combination with this spray. The individual treatments can be combined with other crop protection measures (e.g. aphid control). The combined application of C-complex at 25-30 l/ha eliminates the need for other fungicides and other microelements (boron, magnesium). At the same time, the rate of N fertilizers applied before sowing can be reduced by 35-40 kg/ha N active ingredient. In the case of heavy mildew infestation, a combination of low-cost sulphur-containing products will give good results.
