Against the hop aphid

, : Against the hop aphid. Zashchita Rastenii Moskva (3): 37

Field trials carried out against the hop aphid on hops in the Zhitomir region of the USSR showed that the pest had developed resistance to phosphamide but was susceptible to Sumicidin However, because of environmental effects, fenvalerate should be used only in areas with a deep water level, and a waiting time of 30 days should be observed.
