Abstract

One of the primary crops grown in the Republic of Uzbekistan is cotton. Root rot and gommosis, two cotton sprout diseases, seriously harm cotton cultivation. Some illnesses were shown to have significantly increased in some years. Cotton seeds coated with fungicides are sowed in Uzbekistan. Yet, outbreaks of cotton root rot and blight were frequently seen under production-related circumstances. The gums that protrude from the surface of the cotton plant's damaged organs gave gommosis its name. Many aspects of cotton's growth, including the cotyledons, leaves, stems, bracts, bolls, and fiber, are impacted by gommosis. Among the common diseases that cause significant damage to cotton are diseases of seedlings - this is gommosis and root rot. The article is devoted to the study of the action of preparations: Cruise Extra Cotton 362 g/l, Record 34% against pathogens of cotton seedlings, and iminogommosis and root rot. On the basis of the conducted studies, it was found that the studied preparations have an effective effect on the susceptibility of cotton seedlings to root rot and gommosis. The biological effectiveness of the preparation Record 34% against root rot and gummosis was 86.4% and 93%, and the preparation Cruise Extra Cotton 86.1 and 77%.
