Abstract:
Under laboratory conditions the bactericide action of certain
biological products proceeded from three stems cultures of Bacilus subtilis
were studied. The toxicity of antagonistic stem cultures against pathogenic
bacteria Agrobacterium tumefaciens, Pseudomonassyringae pv,tomato of
agriculture plants were tested in vitro. The action of the three stems using the
culture medium inclusion method showed that the inhibitory action
percentage and calculation limit concentration and corelation coefficient.
The results of our studies it is recommended the use of the following biopreparation: bactericide product ICC F84 + ICCF 284 – isolated of
couchgrass and dried cereals; ICC F84 + ICCF 382 – isolated of couchgrass
and barley; ICC F84 +ICCF 285 - isolated of grass and medicinal. Limit
concentration 50% situated a value 2%. Biological products has been
experiments in control crown galls by Momordica cultivated in greenhouse,
through application seed treatments.
