| Abstract | ||
| The aim of the present study was to test the effect of supernatant concentration of trichoderma harzyanum Fungus on best control. The result showed that the concentration 20 ml/liter of dist .water was the most effective on Mortality percent of larval stages (3rd , 4th , and 5th ) of Khabra insect and it was 7.8% while the other concentrations (10 and 1s )ml /liter did not show any effect . The third larval Stage was the more sensitive. since the mortality rate reached 12.8% while the fifth larval stage was less sensitive (1.7 %) . The effect of treatment period on mortality rate reached the maximum after 6 days of treatment (18.9% )while it was 2.2% after the first and the second day . the interaction between the stages and period gave the 11th larval stage and the 6th day gave higher mortality rate (26.7%). | ||
