Variety traits

Herbicide resistance of chicory

Cichorium intybus L.

Chicory does not possess genetically determined varietal resistance to herbicides. The crop's response is determined by species-specific selective tolerance to active ingredients, where the safety of application depends on strict adherence to dosages and plant growth stages.

In the reference 9 varieties crop Chicory, where this is mentioned in the description.

In chicory breeding, the trait of genetic resistance to herbicides is absent; therefore, the assessment of the crop's response is based on studying the selective toxicity of specific products. The primary method for determining the suitability of crop protection products is evaluating the level of phytotoxicity, which manifests as burns, chlorosis, or necrosis of the leaf blade, as well as analyzing the crop's capacity for regeneration after treatment.

The criterion for the acceptability of herbicide use in crops is the absence of a significant reduction in root yield and the maintenance of raw material quality indicators, specifically inulin concentration. Due to the lack of varietal resistance, the crop's agronomy is limited by strict application regulations and the mandatory combination of chemical protection methods with mechanical inter-row cultivation.
