It may be a heck of an aphid year! Here’s an update:

• Populations are low
• Aphids are present in most fields
• Aphids are easily found on the top trifoliates
• Aphids like warm, dry weather
• This is very early for soybean aphids, yet does not mean that we will have high populations
• Don’t treat if aphids are below the threshold of 250 aphids/plant
• If we treat too early, we may need to treat again later
• There are many sources of mortality for aphids, such as lady beetles and fungal diseases
