tailieunhanh - Pests and pathogens of trees and shrubs spreading in the north-eastern part of the greater caucasus (Azerbaijan)

İn 2015-2017 years has been studied influence of various pests and pathogens in the conditions of in situ and ex situ to the trees and shrubs spreaded in the studied area, identified their species composition and morphological characteristics. It was determined that some widely spread pests are damaging many types of plant. Such pests was relates silkworm (Ocneria dispar L.), maple mealybug (Phenacoccus aceris Sign.), false acacia (Parthenolecanium corni Bouche.), Oyster-shell scale (Quadraspidiotus ostreaeformis Curt.), San Jose scale (Quadraspidiotus perniciosus Comst.). Chionaspis salicis L., Quadraspidiotus pyri Licht., Operophthera brumata L. includes to the pests that most widely spread on the studied plants. The same pest that spreads on the many species of plants is affected by varying degrees, ühich becomes it more dangerous for some plants. As a result of the observations, became clear that, Phyllaphis fagi L., Cryptococcus fagisuga Lndgr. spread on the eastern pistachio, Unaspis evonymi Comst. spread on the European guelder rose are damaged only the species of one genus. During research was found widely spread pathogenic fungi on the studied trees and shrub plants. Pathogenic fungi such as Fomes fomentarius Gill., İnonotus obliquus (Pers.) Pil., Oxyporus populinus (Fr.) Donk. causes disease in many plant species. These pathogenic microorganisms causes white, brown, and velvety decay on the studies trees and shrubs. The results of the researchers was show that the pests in the conditions of in situ on plants meets more. In the condition of in situ plants more undergo to the diseases of pathogenic fungi. This difference can be correlated with environmental factors and lack of agrotechnical service in the conditions of in situ. | Pests and pathogens of trees and shrubs spreading in the north-eastern part of the greater caucasus (Azerbaijan)
