Field Crop News
Our reports continue to indicate very mild disease and insect pressure.
The PA Soybean Board through the Penn State Field and Forage Crops Team sponsors an extensive network of on-farm, field scale research projects. Periodically, participating farms are highlighted in Field Crop News and the PA Soybean Board website.
This summer, some interesting differences show up between tillage and no-tillage treatments in our long-term tillage studies in Centre and Lancaster Counties. Tillage practices have been in place for 38 years in Centre County and for 12 years in Lancaster County.
Rainfall during the next two days will help with current drought conditions, but long-term relief is still uncertain.
Potassium (K) deficiency symptoms are appearing in corn fields around the state. Their cause may not be simple lack of Potash.
Perilla mint contains ketones that cause acute respiratory distress syndrome in cattle (ARDS), also called panting disease, which is often fatal.
Summer Heat and Drought are revealing differences in drought stress within and between fields. Many growers are now seeing the benefits of good soil management practices and strategies. What practices and factors affect a field’s water supplying capacity?
Insect and disease pressure remain low across most soybean fields in Pennsylvania. Grasshopper and Japanese beetle feeding damage being the two most prevalent insect pests found, with a low level of Soybean Aphids detected in a few fields. Little to no diseases of consequence were observed.
Get a chance on July 21st to see how eleven different soybean herbicide programs perform on-farm.
It will feel sticky around here the next few days, but reprieve is on the way.
Weed-free start and appropriate glyphostate/(ALS) -resistant marestail/horseweed are critical concerns for double crop soybeans in some areas of the state.
Choices for post-grass herbicides and the correct rates to control volunteer corn depend on the height of the corn.
Grasshoppers, Japanese Beetles and Aphids are showing up now but pressure from diseases appears low thus far.
Organized, widespread precipitation is not anticipated for the next 7-day period.
Two migratory pests that are relevant for field and forage production have arrived again in Pennsylvania.
At noon eastern time on June 30th we will get the more frequent "stocks" report along with the highly anticipated annual "acres" report.
Current report: Our reports indicate very mild insect pressure, though grasshopper populations seem to be growing with the warmer temperatures. Slug activity has slowed down a lot as dry conditions have spread. Very little disease has been reported. Our scouting efforts indicate that insects, slugs, and pathogens are not posing a great threat to our sentinel soybean fields, and I would expect this to be the case the great majority of fields in PA; thus, insecticides and fungicides are likely not necessary, but scout your fields to find out for yourself.
