| Abstract | ||
| Laboratory study was conducted to study the effect of some inorganic salts (MgSO4, CaCO3, Boric acid) in the effectiveness of biopesticide Belitherol (B. thuringiensis var kurstak). Results of this study showed that all the inorganic salts which were added to biocide bacterial Belitherol were compatible with the bacteria B. thuringiensis var kurstak, and they caused activation and increase in the number of colonies of bacteria, the highest increase for the colonies by MgSO4 effect that caused five fold increase Comparison with the control, and reached three folds by Boric acid effect, while, CaCO3 was least activation for bacteria, the percentage increase in the number of colonies were twice fold of the control. The salts of inorganic caused increasing in the effectiveness of Belitherol on the third instar larvae of the beetle Akhabra, the highest activation percentage for mixture (Belitherol + MgSO4) was amounted to 73.75% (16.87% potentiation + 56.88 synergism), followed by the mixture (Belitherol + Boric acid) with activation percentage was 67.58% (34.72% potentiation+ 32.86 synergism), while the least activation by mixture (Belitherol + CaCO3) was 60.24 (22.71% potentiation+ 37.53 synergism). | ||
