Effect of Application with Fungicide Fortin Pro 25 WP on Nutrients Content in Okra Fruits

Abstract

Okra fruit systemicity and fungicide residues from Fortin Pro25WP were the focus of a field study done by the College of Agriculture at the University of Kufa in the years 2021 and 2022 AD. Treatment effects on okra fruit levels of the fungicides’ active ingredients were statistically significant (P0.05) for both propamocarb hydrochloride (ug/g) and metalaxyl (ug/g). The highest levels of the pesticide were found in the pesticide-only treatment, the next highest levels were found in the fungicide Fortin Pro + the bacteria A. chroococcum that contains the substance, and the lowest average levels were found in the bacteria A. chroococcum + Fortin Pro + R. solani treatment. The highest concentration occurred within the first hour after application, whereas the lowest occurred nine days later, at a concentration of 2.73 ug/g. On day nine of A. chroococcum + Fortin Pro + R. solani treatment, the pesticide residue content was the lowest. When applied to a plant that had not been inoculated with the pathogenic fungus, the fungicide Fortin Pro 25WP significantly increased the nitrogen content of the fruits. However, when applied to a plant that had been inoculated with the fungus, the fungicide significantly decreased the percentage of nitrogen (1.91%) in the fruits. In the fungicide treatment alone (without the pathogen), the fruit recorded the highest rate of phosphorus and potassium content, which was also significantly different from the fruit of the other treatments. Also, in the presence of Azotobacter chroococcum, the interaction treatment of Fortin Pro + R. solani yielded a fruit potassium percentage that was much lower than the control.
