Abstract

The article offers a comprehensive exploration of the geographical distribution of wheat fusarium, focusing on both central and select southern regions within Uzbekistan. The study delves into the symptoms of fusarium disease and elucidates the extent of its impact on crop productivity. Furthermore, it investigates the spread of this disease across diverse soil and climatic conditions within Uzbekistan, spanning the period from 2021 to 2023. The research outcomes underscore critical findings related to fusarium-infected plants. Notably, infected plants exhibit an absence of a budding phase, suggesting a disruption in their growth cycle. Experimental evidence confirms the formation of only one spike from a single plant, emphasizing the negative effects of the disease on plant reproductive structures. The article additionally examines the quantitative aspects of wheat production in relation to fusarium. Findings reveal that fields plagued by the prevalence of fusarium exhibit a lower spike formation rate, with approximately 250-300 spikes forming per square meter. This figure contrasts with healthier plants, which yield a more substantial output, exceeding 400 spikes per square meter. By offering insights into the geographical spread, symptomology, and productivity repercussions of wheat fusarium, this article advances our understanding of the disease’s impact on agricultural systems. The presented results provide valuable information for practitioners seeking effective management strategies against fusarium, ultimately contributing to the maintenance of healthy wheat crops and sustained agricultural productivity.
