Field Crop News
The interest in rye for distilleries continues to grow and so our research work will continue to develop to help producers and processors with improved information.
As summer progresses and the soybean crop nears maturity insect issues become less consequential while other late-season yield robbers take center stage.
Warm and wet weather expected through September.
Zach Larson joined Penn State Extension in early August as the Field and Forage Crops Educator for Blair, Huntingdon, and Fulton counties. Zach is housed in Martinsburg, Blair County.
We toured Southeastern PA on Monday this week looking at the progression of Palmer amaranth and waterhemp in Pennsylvania. We identified some positive and not so positive progress.
With the dry weather encompassing most of Pennsylvania this summer, a close eye should be kept on corn silage moisture and maturity so the proper harvest time can be achieved to produce quality silage.
As we receive more much-needed rain, reports continue to indicate very mild insect pressure and little disease. Grasshoppers and Japanese beetles are still the primary defoliators, but populations remain below the economic threshold (15-20% defoliation). We expect these results to represent the majority of soybean fields in PA, but scout your fields to find out for yourself.
A critical component of soil management is to plant cover crops as soon as possible after harvest of the previous crop.
The welcome rains have refreshed our crops but made the soil moist just prior to corn silage harvest. The soil compaction threat therefore has increased significantly.

Showers this week will bring some relief to a very dry Pennsylvania.
As we hover around the R3 stage in many of our soybean fields, you may be considering a fungicide application.
PPO resistant pigweeds are increasingly more common in the cornbelt as we rely more on these herbicides for weed management in soybean. Using integrated weed management tactics that include effective cultural and mechanical control measures are more important than ever.
The Pennsylvania Department of Agriculture has launched a new Palmer amaranth and waterhemp website that has management information and includes a short survey for these two problem pigweeds in Pennsylvania.
Hot dry summers can be the worst enemy of high quality productive pastures. Dry weather often results in over grazing, and before you know it, grass and broadleaf weeds have replaced desired species.
We could see some rain this week on drought stressed forages and this could set up for nitrate accumulation silo gas and wetter forage next week. This article shares a few ideas for managing that situation.
Reports continue to indicate mild insect pressure and little disease. Grasshoppers and bean leaf beetle appear to be the populations that are causing most significant defoliation with some fields approaching by not yet exceeding the economic threshold (15-20% defoliation).
