This study was conducted to detect the pathogenic fungi that associated with watermelon seeds and assess their pathogencity, Evaluating the efficiency of plant shoots clove powder Syzygium aromaticum [L.] in suppression the activity of two pathogenic fungus Alternaria alternata , Fusarium oxysporum Were also demonstrated agreat effection in some growth parameters that have been measured.

The results showed hat Alternaria alternata, Fusarium oxysporum had a significant impact in the percentage of seed germination using the Using filter blotter technique in laboratory 56.25, 55.75, respectively, compared with 90.25 control treatment, fungal extraction were also a significant impaction in reduction the seedling length ( 5, 4.6) cm Compared with 6.6 cm the control and treatment.

Results were showed a great effection of both fungus in seed germination percentage 56, 55, compared with 90 in control treatment, as a in growth parameters (seedling length 14.5, 13.75 cm compared with 19 cm in the of control treatment, the dry weight 0.10, 0.09 grams, compared with 0.16 grams in control treatment) and the percentage of the severity of infection 56.25, 60.75.

The dividen fungicide has a significant impact inhibition the growth of fungus tested 95.50,95.25 clove powder has also a significant impact to inhibition the growth of fungus tested in the laboratory following food poisoning technique based on the percentage redial growth (66, 60.75), compared with 0 control treatment, the test of glass house clove powder show significant impact to both fungus tested in curbing the activity has increased the proportion of Germination percentage of 62, 60.5, 16.75 lengths plants, dry weight 16.25 cm 0.14, 0.14 percentage of the severity of infection 27.75, 31.
