Role of chelated fertilizers` and nano-particles application for formation of elements of productivity аt artificial infected with phytoplasmas and virus
Abstract
Aim. Investigation of the role of chelated fertilizer and nanoparticles in the formation of elements of productivity for artificial infection of phytoplasmas and wheat streak mosaic virus. Methods. Microbiological, serological, biophysical, biometric, statistical. Results. In the field conditions, the effect of leaf treatment of wheat plants with chelated fertilizers and nanoparticles of copper and silver for artificial infection of phytoplasmas and WSMV on the magnitude of the quantum efficiency of photosystem II for controlling replication of the virus by the method of immunoassay analysis and the study of the influence of nanoparticles on the development of phytoplasmas, as well as the weight of 1000 grains of wheat was investigated. Conclusions. Foliar treatment with chelated fertilizer can activate the plant’s phytoimmunity of wheat plants, thus preventing the active replication of the virus in the plant organism, thereby reducing somewhat the loss of productivity for the damage to the WSMV. The use of foliar treatment of wheat plants with 1% solution nanoparticles of silver and copper citrates can stop the development of phytoplasma infection, which allows maintaining a level of productivity close to the intact plants.
