AbstractErwinia amylovora is the causative agent of apple and pear blight disease .fireblight is one of the most dangerous disease of seeded fruit in many regions ofthe world which causes necrosis of the host tissues and the loss of crop .they canbe mentioned as apple pear beech and hawthorn as the most importanthosts.Currently, the main way to control this disease is to use spraying withcopper poisons. Although copper poisons are not highly toxic to humans, theircontinuous use can lead to the accumulation of copper in the ecosystem and thecreation of various types of poisoning and resistance in different organisms.One of the new methods in controlling plant pathogens is the use ofnanoparticles. Nanoparticles may not only have an inhibitory effect on the target56bacteria, but they can improve or prolong their effect when mixed andformulated with common toxins. The use of different nanoparticles in thecontrol of some plant pathogens has already been reported; But most of theseresearches have been done using nanoparticles prepared in the chemicalindustry.In the present research, first in the spring of 1400, trees with anthraxsymptoms were visited in East Azarbaijan region, Tabriz city, and samples ofinfected tissues were prepared. After isolation, the causative bacterium wasmolecularly identified using the specific primer of the pel region. Citrus fruitswere used to prepare green synthesis copper nanoparticles. For this purpose,copper nanoparticles were synthesized in the laboratory using lime extract and5% sulfate. Pomegranate skin was also used to prepare nano sulfur by greensynthesis .Prepared nanoparticles inconcentrations of 100-300-1000microliters/liter were prepared and mixed and formulated with Copper Bordofixpoison. The effect of these treatments on the growth of the bacterial populationin the NAS culture medium was investigated in laboratory conditions and thechanges in the bacterial population were measured using an ELISA reader at awavelength of 650 nm. The experiment was conducted in a completelyrandomized design in threereplications.Bacteria population changes were measured at 0, 6, 12, 24, 48 hours.Theobtained results showed that in the use of copper nanoparticle, the coppertoxin of Berdofix alone can control bacteria by 83.7% after 48 hours, but thisvalue increased to 96.9% with the addition of copper nanoparticle. In the use ofsulfur nanoparticle, the results showed that the Copper Bordofix poisoncontrolled 84.75% after 48 hours, but this value increased to 94.4% with theaddition of sulfur nanoparticle and reduced the bacterial population by 94.4%.
