Effect of insecticide Alpha Super on phytopathogenic bacteria Рseudomonas syringae of agrophytocenosis of wheat

Abstract

The purpose. To study of effect of insecticide Alpha Super on morphological dissociation of phytopathogenic bacteria Pseudomonas syringae pv. Atrofaciens (McCulloch 1920) Young, Dye and Wilkie 1978, causal organisms of bacterioses of cereal crops. Methods. Classical microbiological and biochemical methods, ability to form a biofilm is studied at growth of P. Syringae pv. atrofaciens in polypropylene trays. Results. It is fixed that insecticide Alpha Super is characterized by negligible toxicity to phytopathogenic bacteria P. syringae pv. atrofaciens. It is shown that at action of the specimen Alpha Super amount of R-forms of P. syringae pv. atrofaciens increases. Properties of the induced by insecticide Alpha Super R-forms of P. Syringae pv. atrofaciens UKM V-1011 are also studied. Conclusions. Insecticide Alpha Super causes morphological dissociation of phytopathogenic bacteria P. syringae pv. atrofaciens. R-forms of P. syringae pv. atrofaciens, induced by insecticide Alpha Super are characterized by greater resistance and form biofilms better, that increases surviving of these phytopathogenic bacteria in agrophytocenosis.
