Cruciferous crops are attacked by many diseases caused by viruses, bacteria and fungi. Of economic importance are the causal agents of mosaic, bacteriosis, damping-off in seedlings, clubroot, downy mildew, powdery mildew, black leaf spot and Sclerotinia (white) rot in cabbage.

Agrotechnical and organizational practices in seedling production

- Growing seedlings far from seed production and other cruciferous crops;

- Growing in a pathogen-free substrate;

- Disinfected pots, trays, etc.;

- Optimal soil moisture;

- Optimal seedling density; 

- Removal of the first diseased plants and their destruction far from the seedbeds;

- Treatment with plant protection products when necessary.

Agrotechnical and organizational practices after transplanting

- Transplanting healthy seedlings;

- Optimal crop density;

- Weed and volunteer control;

- Strict phytosanitary regime;

- Optimal soil moisture regime and optimal agrotechnics;

- Balanced fertilization;

- Monitoring for the occurrence and spread of pests;

- Introduction of crop rotations;

- Mechanical collection of severely affected plant parts with disease spots and their destruction;

- Treatment with plant protection products. Alternation of plant protection products with different functional groups to prevent resistance;

- Application of plant protection products with a short pre-harvest interval during the harvesting period.

 

The pest control system for cruciferous crops is published in issue 6/2018 of the journal “Plant Protection”.
