Abstract
"Soybean is an important economical crop used for human consumption, animal feed and industrial raw material. Also, soybean is succesfully used in crop roatations with the main cereal crops because it’s biological nitrogen-fixing capabilities. A great diversity of pests and diseases including nematodes, insects and phytopathogenic fungi are known to affect soybean crop. From plant emergence to grain maturity, pests Tetranychus urticae and Etiella zinckenella, pseudofungi Peronospora manshurica and fungi Fusarium sp. and Botrytis cinerea can cause economic damage. In this study was evaluated the influence of tillage systems, different types of fertilizers and pesticide treatments on the most economical important diseases and pests of soybean crop in a field experiment at Agricultural Research and Development Station (ARDS Turda) in the climatic conditions of 2020. Teo TD, an early maturing soybean variety created at ARDS Turda, was used for the experiment. Based on the assessments made, soil tillage system, fertilization and control of pests and diseases have differently influenced the downy mildew and T. urticae attack. To reduce the attack of pathogens in soybean crop, the best technological option is plowing, balanced fertilization and application of fungicides, either without or in combination with an insecticide. The T. urticae populations developed on mineral, organic and green fertilized plants. Integrated control methods must combine agro-technical measures with the application of chemical treatments in accordance with the warning of the appearance of the first adults. "
