Back in 2013, there was a burst of interest in a new exotic soybean pest that was approaching Pennsylvania, commonly referred to as kudzu bug. Just last week, entomologists announced that they found kudzu bug adults and egg masses on soybeans in Beltsville, Maryland

Now is the time to scout for Palmer amaranth and waterhemp and remove or destroy it to prevent seed production and spread.

Pasture managers and hay producers have a window of opportunity in the late summer and early fall to improve existing or establish new stands through seeding.

Timeliness is extremely important to reap cover crop benefits. Several species have to be planted in August or early September to make sure goals such as nitrogen fixation, nitrate pumping from the subsoil, compaction alleviation, or forage provision can be met.

Our initial trials with Industrial Hemp are providing some guidance on best production practices for this crop in the future. The crop will be featured at Ag Progress Days.

Reports this week from across the state indicate low pest populations in the soybean fields we are scouting. Our reports from this week identify Japanese beetles, and grasshoppers as the primary defoliators, but aphids and brown marmorated stink bugs are present in some fields. Remember that vegetative stages soybeans can tolerate up to 25% defoliation without dropping yield and reproductive stage beans can tolerate 15%. So do not overreact if you find some feeding damage in your fields. For diseases, reports of Septoria brown spot and frogeye leaf spot are present in some fields, but pest pressure is low.

After some soaking rains late last week, some very seasonal late summer weather will ensue through the end of this week followed by a brief cool down.

August 2, 2017

Preparing for fall and winter on livestock operations is something that producers need to think about long before those seasons arrive. Managing pastures for fall and winter grazing should be done as summer draws to an end.

August 2, 2017

Reports continue to indicate very mild insect pressure and little disease as soybeans across the state continue to bloom and are starting to form pods. Japanese beetles and bean leaf beetles are 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.
