Effect of Some Biological and Chemical Treatments in Controlling Date Palm Fruit Rot Disease

Abstract

Abstract The College of Agriculture, University of Basra/Department of Plant Protection performed the 2021-2022 research. with the goal of testing biological and chemical therapies for date palm fruit rot in Sayer and Khadrawi cultivars. Bioagents included bread yeast Saccharomyces cervesiae, Cheatomium globsum, and chitosan nanoparticles. Chemical treatments included silver nanoparticles. Cheatomium globsum + silver nanoparticles had the lowest average infection rate of 4.82%, compared to 36.62% for the control treatment. Neither variety differed significantly. The statistical analysis of the interaction between the study treatments variety showed significant differences between them, as the treatment of cheatomium globosum + silver nanoparticles reduced the average percentage of disease infection to 3.83% and 5.80% compared to the control treatment, which had an average infection rate of 36.23% and 37.00% for Al-Sayer and Khadrawi, respectively. The Control treatment had the highest average latent infection rate of 81.67%, while the cheatomium globsum and silver nanoparticles treatment reduced it to 12.83%. Khadrawi had 38.525 latent infected rats of date palm fruit rot, whereas Syer had 33.71. The other cultivar had the lowest latent incidence of palm fruit rot disease at 33.71%. The average was 38.52%. Experimental treatments did not interact significantly.
