Carrot (Daucus carota L.) of the plant Alternaria disease (review)

Abstract

Nowadays, fungi-related illnesses are widespread in all nations that cultivate vegetables, which lowers output. Carrots are harmed by pathogenic fungus both during the growing season and while they are in storage, which reduces both the amount and quality of the crop. From this perspective, it is critical to investigate the bioecological characteristics of the fungus that cause illnesses in carrots and to carry out research on the creation of effective and ecologically friendly countermeasures. Alternaria diseases Daucus carota L. is one of the most common diseases of the carrot plant and often has a significant impact on the yield of carrots. Carrot Alternaria several fungi belonging to the genus are harmful and the symptoms of the disease are manifested in the form of leaf spotting, black crown and black rot of roots. Protecting carrots from these diseases is one of the main tasks facing field experts. Therefore, this research intends to make a summary of literature data on Alternaria leaf spotting, root rot and black rot of young seedlings caused by Alternaria fungi. The results showed that the most stable yielding carrot hybrid was F1 Santa Cruz taken as the control variant, which showed the highest yield, accounted for 113.7, however, its resistance to alternariosis was slightly lower, which was 2.3. In this regard, it is recommended to continue research on other new hybrids.
