Abstract: Reduction in the use of insecticides and their combined application with different products, including mineraloils in order to reduce their negative impact on the environment is an environmentally friendly approach inconventional farming conditions. The experiment was carried out during the period 2014-2015 in IFC-Pleven and aimed to study the effect of application of mineral oil Akarzine (400 ml/da), alone and in combination with reduced doses (0.03 and 0.01%) synthetic insecticide (Eforia 045 ZC) on the productivity and quality of alfalfa forage. The results showed an increased crude protein content (3.4-9.5%) and decreased crude fibre content (1.4 - 7.9%) in the biomass obtained, as well as a higher productivity (13.8-38.7%) of the plants. The combined application of Akarzin with Eforia 045 ZC allowed a reduction in the insecticide dose to 0.03 and 0.01%, while at the same time the effect on productivity exceeded this one of Ephoria 045 ZC applied alone at the highest recommended dose (0.05%).
