A complex of measures for white head cabbage (Brassica oleracea convar. capitata var. alba L.) protection against weed vegetation, diseases and pests for seedling and non-seedling methods of crop growing is developed including pre-planting seed treatment and taking care after seedlings ,main phytophages, phytopathogens and weed plants number monitoring during vegetation, successive carrying out of protective measures for their harmfulness restriction, phytoregulators application for plant resistance raising to unfavourable weather conditions, what has allowed to decrease crops and plantings weed infestation for 87-92%, decrease phytophage population density for 84-94%, decrease leaf apparatus diseases development for 43%,decrease a degree of bacteriosis plant infection for 40-52%. As a result of successive plant protection means application against pests, diseases and weeds against a background of carrying out the recommended agrotechnical measures, 38,6 t/ha of standard production has been obtained while cabbage growing by seedling technology and 41,0 t/ha – by non-seedling technology; profitability - 75,7and 167% , accordingly.
