Protection of garden carrots in the phytosanitary technology of cultivation of the Southern Urals

The purpose of the research was to study varieties and hybrids of garden carrots and protect them when cultivated using phytosanitary technology in the Southern Urals. The objects of research were varieties and hybrids of garden carrots, harmful organisms and plant protection products. When studying varieties and hybrids of the Nantskaya variety type, the standard Nantskaya 4 variety significantly exceeded the total yield by (32.6 t/ha), the Zhar Ptitsa variety by 3.8 t/ha, the Turkish Delight variety by 10.2 t/ha, the Krasnaya Zvezda F1 hybrid by 4.1 t/ha and the Semenovna F1 hybrid by 5.5 t/ha. The standard Shantene 2461 variety produced a total yield of 32.3 t/ha and marketability was 80.8%. The standard Vitamin 6 variety significantly exceeded its yield by 39.9 t/ha, Sentyabrina by 37.7 t/ha, and the Sankin hybrid lyubov F1 by 34.7 t/ha. According to the results of the plant protection experiment, the total yield for the Shantene 2461 variety in the control was 28.7 t/ha, the use of protective agents ensured an increase in yield according to scheme No. 1 - 12.8 t/ha, according to scheme No. 2 - 10.3 t/ha, the use of biological agents according to scheme No. 3 ensured the safety of the harvest of 3.9 t/ha. On the Sankin lyubov F1 hybrid, the yield in the control was 25.1 t/ha. Plant protection with modern preparations provided an increase in total yield from 11.7 t/ha according to scheme No. 3 to 18 t/ha according to protection scheme No.1. In the protection options, the yield of commercial root crops significantly increased.
