The evaluation of ecologically safe methods of table carrot protection against pests and diseases allowing to maintain the yield up to 34-42 c/ha and get 7% of standard ecologically pure production is done. It is experimentally established, that processing of carrot seeds with fitoprotektin (40 ml/kg) and mikolin (200 ml/kg) raise field germination in relation to the control on 8 and 6% accordingly, reduces seed contamination with a complex of phytopathogenes in 2,3-3,7 times. Spraying of crops with batsiturin at 2-fold application provides decrease damage of carrot crops by leaf hopper on 89% and till the end of vegetation constrains number of phytophage below level of an economic threshold of injuriousness. The spent complex of protective actions against pests and diseases of carrots makes positive impact on crop formation. Thus the exit standard ecologically a net production makes 75%
