BACTERIOSIS OF ELM TREES IN AGRO-FOREST-RECLAMATION STANDS OF LOWER VOLGA AND CONTROL OF IT

The work covers the elm stands of Astrakhan, Volgograd regions and Kalmikia. The aim is to study the bacteriosis of elm trees in the agro-forest-reclamation stands of Lower Volga and to develop the protection measures from disease. The evaluation of influencing different parameters of the wind-breaks and forestry cares on the damage of elm trees by a bacteriosis has been performed, the disease agents have been distinguished and determined, the bacteriosis transmission procedures in the agro-forest-reclamation stands have been studied. The disease diagnosis has been developed, the new principle of ordering trees damaged by bacteriosis for the felling has been proposed, the measure system on the disease protection has been developed. The measure system on the protection of elm tree for the agro-forest-reclamation stands of Lower Volga has been introducedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
