Abstract
The study was carried out during the 2022 agricultural season in the greenhouses belonging to the - College of Agricultural - Al-Ramadi, the study aimed to investigate the efficacy of alcoholic extract of Solanum eleaegnifolium, potassium silicate and ungicide Previcur Energy in normal and nano formula to control downy mildew disease on cucumber crops caused by the fungus Pseudoperonospora cubensis. The results showed that the normal potassium silicate treatment completely prevented the disease during the length of the season, with an infection severity rate of 0.00%, compared to infection with artificial contamination of 45.90%, followed by the treatment of nano fungicide 4.60%. While the treatments of alcoholic extract and nano of nightshade wild gave an infection severity of 7.12% and 8.67%, respectively, then the treatment of nano potassium silicate was 10.48%. In general, we find that the field experiment results have involved all treatments in increasing some growth characteristics such as plant height, fresh and dry weight, and the number of leaves.
