Abstract

The efficiency of the dispensation was tested for local bacterial isolation, on slices of the variety Alison A8، G6، B4، AP1 about Rhizoctonia solani, Isolate (RS 7) was the most virulent; the control showed a typical growth of Rhizoctonia solani after four days of experience. Without significant differences between the isolation A8، G6، B4 following Bacillus, where these insulations did not allow fungi growth while fungi were 1.4 cm in the treatment of AP1 isolation from the rastic/ branching bacteria the impact of both isolation A8, B4, AP1 is limited to inhibition the growth of fungi as the G6 isolation affected potato slices, with tissue analysis and slice mold within 48 hours of the experiment. studied in the half field experience single and shared partnership for bacterial isolation A8, AP1with a concentration of 109 CFU/tuber and rizolex pesticide with 0.025 ppm effective material and the concentration of 2000 ppm is an effective substance in curbing the pathogenic mature During cropping season 2020 device of tubers before agriculture for 30 minutes by bacterial or pesticide. The results indicated that there are no significant differences between bacterial and control transactions except for treatment of 0.025 ppm effective substance where the average disease in the treatment of 3 according to hexagonal measure while the disease has not exceeded the treatment of isolation A8 0.33, as well as its high ability to inhibition the fungus of virulent, and she worked as a vital catalyst for the grow the of potato seeding compared with the healthy control plants, where was average wet weight in the treatment of isolation Bacillus A8 4.87 gram and medium-length plant length 29.60cm while wet weight was in  healthy control plants studies 1.76 gram and medium length 28.60 cm .

Key words: Rhizoctonia solani, potato slices, Rizolex, inhibition, Bacillus.
