Effectiveness of Some Insecticides Against Potato Aphids

The research indicates the result of a study on the use of some new insecticides from various chemical classes to evaluate the effectiveness of some insecticides from various chemical classes on potato against potato aphids which was conducted in 20th, may 2025, in Research farm, green house and laboratory of Peoples Friendship University of Russia (RUDN) in the conditions of the weather zone of Moscow oblast on potato crops and in conditions of mass development of potato aphids in Moscow city. Potato aphids are a serious problem in the world and especially in Russian Federation. The main aim of research was to evaluate the Effectiveness of four new insecticides against potato aphids. The area of one plot was 100 m2 the insecticides were repeated two times on Potato aphids, the location of the plots were randomized. The result of the study showed that the most effective drug against potato aphids was Flupyradifurone at a consumption rate of -1000 g/ha and the least effective was Pymetrozine at a consumption rates of – 300 g/ha. Insecticides from different chemical classes showed against potato aphids, the highest value of the preserved crop over the study period was noted with the drug Flupyradifurone with a consumption rate of 1000 g/ha and amounted to 20,6 c/ha. Flupyradifurone indicated the highest efficiency against potato aphids on the 3rd day of application - 78%, and reached maximum efficiency on the 7th accounting period - 95.6%. In second place in terms of efficiency was the Dinotefuran at the level of 73% and 90% of phytophage death on the 3th and 7th day of accounting, respectively.
