The objective of the study was to evaluate the effectiveness of Pseudomonas fluorescens and some of the Inducers agents  in the control of fusarium wilt disease on melon plants caused by   Fusarium oxysporum f.sp.melonis. The study also tested the pathogenicity of pathogenic fungi isolates and compared the efficacy of bacteria and induction agents using  Beltanol agents to control this disease. The results of the Fusarium oxysporum f.sp.melonis test showed that FOM8 isolates were the most isolated  using the seeds of the cabbage. The rate of seed germination rate was reduced to 0.00% compared to the control treatment with a germination rate of 100%. Pure isolation of Pseudomonas fluorescens was obtained. The test of the antibiotic susceptibility of these bacteria showed that it has a high resistance against pathogenic fungi. Pseudomonas fluorescens inhibited the growth of Fusarium oxysporum f.sp.melonis on the PSA by 92%. While the results of the antibiotic test EM1 and  herbal extraction Ascophyllum nodosum against the isolation of fungus Fusarium oxysporum f. sp. Melonis in the PSA has achieved an inhibition rate of 88% and 82%, respectively. When Fusarium oxysporum f.sp.melonis was performed under the field conditions, Results also showed that Pseudomonas fluorescens and induction factors reduced the severity of the disease to 6% compared to the treatment of pathogenic fungi only, which reached 44% severity, and showed a significant increase in the rate of soft weight and total length The length of the plant was 45.3 cm after 45 days compared to the control treatment (pathogen only) which was 18.6 while the soft weight of the vegetative and root group was 12.8 g compared with the treatment of the pathogen only, which amounted to 5.3 g.

The study was conducted to evaluate the quality of samples of different types of local honey produced from different sampling from the Middle Euphrates and imported areas at Karbala University for the period from 1 / 12-1 / 9/2017. The sample included 11 samples. The results showed variation in the percentage of humidity, (16.3% - 19.8%). It was noted that the ash content ranged from 0.2211-0.5433%. The pH values ​​of the honey samples were different, with the highest pH value in model 9 being 3.9, the lowest pH was 2.2 for Fig. 5, and the total pH scores were 22.8 mg kg for Model 9, The results showed a significant difference in the values ​​of efficacy. The results obtained from the sugars estimate showed a difference in total sucrose and glucose, with the highest value of 73.9% for model 11 while the lowest value for total sugars was 64.3% for Fig. 9. For the models given the highest values For the sample 2 was 38.9 mg  g and the lowest value of the sample No. 9 was 22.4 mg  g. The results of the detection of the enzyme calcoside oxidase showed a clear difference in the effectiveness of the enzyme was 0.99 mmol  mol  min, 11 was less effective for the enzyme in model 2 amounted to 0.22 mmol  mol  min. The results of the study within the limits of the Iraqi standard. The results show that the majority of the local models of the Iraqi standard for ash, which are not more than 0.3%, are identical to the sample 11 and 10, which are imported honey samples. The ash is below the limit permitted in the Iraqi standard, The results of the study showed that the total acidity ratio of all samples was consistent with the Iraqi standard. The results of the estimate of total sugars within the limits of the Iraqi specifications and the Constitution of the Food,
