With delayed planting, slower crop emergence and frequent rain events, early season pests get a longer period of time to feed on the seed and seedlings. There are a number of pests causing problems right now. Seedcorn maggots are causing injury in both corn and soybean fields. Although higher risk fields include those that have […]
When springs are cool and wet, it results in two things. 1) Difficulty with getting good weed control in before planting and 2) Pushing planting into cooler soils that may cause the seed to sit for a while. Both of these can increase the risk for early season pest issues. Here are some of the […]
The weather is certainly warming up and it looks like the forecast is for more of the same. Things are getting busy and I’ve got a few things to talk about this week. The first is the start of the Western Bean Cutworm Trapping network. Traps should be set up this week and the data […]
When grubs hit hard, forage supplies dwindle fast! Stand loss in hay fields and pastures due to grub damage is becoming more common. Warm open falls and warm springs are ideal for grub feeding activity. (Figure 1) The result is a thin, weedy stand with low yields , and poor resistance to drought. Grubs prefer […]
Despite all this rain, pests are still doing quite well out there, as long as they have something to eat. We had a lot of snow cover this winter which has helped insulate any insects that overwinter and the cool wet soils are helping these soil pests remain active. Some are just waiting for their […]
What a spring so far. Things are happening fast. Given the warm start to the season, we should expect an early start for many of our early season insect pests too. Consider scouting at least 2 weeks earlier than norm. Alfalfa weevils should be active shortly if they are not already (anyone find any yet?). […]
