Syngenta’s solutions The potential of cultural practices to reduce crop losses due to Club Root are limited and chemical treatments to control the fungus are either banned, due to environmental regulations, or are not cost-effective. The best way to combat Club Root is through the breeding of resistant varieties. Syngenta has succeeded, after many years of breeding, to introduce a high level of resistance in varieties of cabbage (Chinese, White & Green), Brussels sprouts, broccoli and cauliflower.

Syngenta will, over the coming years, be introducing this resistance across the Brassica range.

We currently have the following varieties with Club Root resistance:

White storage Brussels Cauliflower cabbage sprouts Club Root (Plasmodiophora Brassicae) is a serious disease affecting Brassica. An Clapton Kilaton Crispus estimated 10% of the total cultured area Clarify Kilazol Cryptus worldwide contract the disease. Syngenta has invested years of breeding to offer a Clarina high level of resistance in their Brassica varieties.

Club Root symptoms Club Root is a soil borne fungal disease which attacks the roots of Brassica crops. It is considered as one of the most economically important diseases of cultivated crucifers. Roots affected by Club Root are swollen and distorted. The damage caused to the roots causes crops to be stunted and, in most cases, there is a reduction in yield. The pathogen survives in the soil for up to 15 years in the form of resting spores released from decayed galls. 3 ABACUS* CRISPUS

All resistances quoted refer only to races or pathotypes indicated at the varieties. Other pathogen races or pest biotypes capable of overcoming the resistance may exist or emerge. Syngenta Seeds Vegetables uses highly elaborate analytical methods to verify specific variety resistances. Specificity of pests or pathogens may vary over time and depends on environmental factors. In order to maximise the efficiency of a resistance, it is highly recommended to mix different ways of control such as growing conditions, plant protection products and genetic resistance as part of an integrated crop management. All data in this brochure is intended for general guidance only and the user should apply it in accordance with their own knowledge and experience of local conditions. In case of doubt we recommend that a small scale trial production be carried out to determine how local conditions may affect the variety. Syngenta Seeds cannot accept any liability in connection with this brochure. Resistance against Club Root is effective against the predominant strains but not against infrequent strains that may occur in some fields in Europe and that may break the resistance. At present very sparse information is available on the type of strains and their occurrence. Separation and identification of the different strains is also technically difficult. For Club Root control we recommend culture measures such as liming, drainage and calcium fertilisation. It is advised to first execute small trials before starting commercial production. Use plant protection products safely. Always read the label and product information before use.
