Attack pathogens and increasing abundance of some insect pests were favored by the climate changes, culture technologies practiced and increasing of cultivated areas with soybeans. The aim of this paper was to evaluate the attack of pathogens in soybean crop and to monitor some pest Lepidoptera species in order to identify technological measures to ensure their control by methods with minimal impact on the environment. The experiment was performed at the Research and Development Station for Agriculture Turda during 2018-2020 period. The best technological option is plowing, balanced fertilization and fungicides application, either alone, or in combination with an insecticide.

"In order to protect agroecosystems and to optimize soybean crop yield from the Transylvanian Plain, the adoption of complex methods of sustainable management with minimal impact on the environment has now become a challenge. Therefore, an experiment was conducted at the Agricultural Research-Development Station Turda in 2018, to provide the best methods for the development of an Integrated Management System (IMS) for phytosanitary soybean crop risks. The field factorial experiment was based on a subdivided parcel design with two replications. Experimental models for soybean crop protection have been developed. Field research was carried out for analyzing the technological (agricultural practices), biological (diseases, insects, pests) and environmental (climate change, methods of improving soil fertility with phytosanitary risk by applying environmentally friendly products) factors affecting soybean crop yield and quality. An entomological sampling strategy (pheromone traps, plant surveys) was used for evaluating the IMS environmental risk and methods for increasing plant resistance to biotic and abiotic stress factors were also studied. The obtained data was correlated with the production values for the 3 experimental factors: the tillage system, fertilization and treatments. The following pests were recorded, soil pests Coleoptera, Agriotes larvae, Opatrum, dipterans Delia platura and D. florilega, vectors of viruses and phytoplasmoses, cicadas, aphids, trips and the common red spider Tetranychus urticae, defoliating omissions Vanessa cardui, owls Autographa gamma, Mamestra suasa, M. oleracea, Agrotis segetum) etc. In the climatic conditions of 2018, most frequent pathogens were downy mildew (Peronospora manshurica and bacterial blight Pseudomonas glycinae."
