Soybeans
Volume 64 Number 4 Date 05/23/2019 SOYBEAN APHID - Aphid colonization of emerging soybeans will likely be delayed until the second week of June this season, considering only 12% of the state's intended soybean crop has been planted so far. During the last decade, the first recorded aphid observations have ranged from as early as May 24 in 2007 to as late as June 9 in 2009. In most years, aphids are detectable by the time soybeans reach the V1 stage. BEAN LEAF BEETLE - Overwintered adults were found in two of 40 alfalfa fields sampled in the past week. The beetles were collected in Grant and Vernon counties. Populations of this soybean pest were probably reduced to some extent by the polar vortex in late January and early-season defoliation problems are not anticipated. -- Krista Hamilton, DATCP Entomologist
