THE EFFECT OF INSECT PATHOGENIC FUNGI Beauveria bassiana AND Paecilomyces lilacinus IN THE CONTROL OF SEEDLING DAMPING OFF DISEASE IN OKRA

The insect pathogenic fungi possess different mechanisms in eliminating the pathogenic fungi of the plant, and these fungi may have a double effect on the different pests that infect the plant. Two types of the insect pathogenic fungi Beauveria bassiana and Paecilomyces lilacinus were used in this research to control the pathogenic fungi of okra roots and tested them led to a decrease in the germination percentage in okra seeds as the germination percentage reached 61.33, 55.89, 45.33% for M. phaseolina, R. solani and fungi. F. Solani, with a significant difference, from the control treatment, which amounted to 90.54%.. The pathogen R.solani, F. solani and M. phaseolina caused a significant decrease in the death of okra seedlings, and the most effective fungi were M. phaseolina, where the percentage of seedlings dying before emergence was 40.42 and after emergence of 36.78. The results of the experiment of measuring the height of plants showed that the height of the plants was longer in the soils treated with biological fungi, as the height of the plants reached 20 cm after three weeks of the emergence of the seedlings compared to the soils treated with pathogenic fungi, which showed clear significant differences. The causes of root diseases that affect the okra plant because it contains enzymes, antibiotics and chemicals that have a great effect in the inhibition process. The concentrations were used in this experiment 10%, 20% and 30%.
