As your canopies close and humidity levels rise, you can bet the fungi that cause crop diseases are getting happy. Scouting right now is going to be your best bet for making good fungicide decisions for your fields.

Corn and soybeans have survived a rough spring with weather and pest concerns, but weather and yield prospects have been improving during the last two weeks.

July 12, 2017

Most soybean fields appear to be growing well and are starting to experience some minor defoliation. Our reports from this week identify bean leaf beetles, Japanese beetles, and grasshoppers as the primary culprits. Remember that vegetative stages soybeans can tolerate up to 25% defoliation without dropping yield, so do not overreact if you find some feeding damage in your fields. For diseases, reports of Septoria brown spot and frogeye leaf spot appeared this week, but populations seem low.

As you make hay this year, pull a couple of your best bales and store them in a dry spot so that when Ag Progress Days rolls around you can enter them into the annual hay show and judging contest.

Commercial and private pesticide applicators looking to obtain PA pesticide continuing education credits can now register for the Agronomic Pesticide Applicator’s School at Rock Springs on August 30th, 2017.

Planting green is a practice where growers delay cover crop termination until cash crop planting. Instead of killing the cover crop 1-2 weeks ahead of cash crop planting, the cover is allowed to grow longer into the spring, which can extend soil conservation and health benefits provided by the cover crop.

Enjoy the cooler weather... Showers, heat and humidity return for the weekend.

With better growing conditions, most soybean fields seem to be growing well and have left slug damage behind (with few or no exceptions, I hope). From the reports we have this week pest populations remain low, bean leaf beetles, silver spotted skipper caterpillars, and leafhoppers are active, but we have not encountered meaningful populations. Remember that vegetative stages soybeans can tolerate up to 25% defoliation without dropping yield so do not overreact if you find some feeding damage in your fields. For diseases, one report of bacterial wilt and perhaps some anthracnose came in this week, so when scouting your fields, look out for these and others that might becoming active.

While slugs are fresh in our minds it may be beneficial to discuss some longer-term slug-management options that might help decrease future slug challenges.

Just a day or two away is one of the more unusual USDA crop reporting dates. At noon eastern time on June 30th we will get the regular “stocks” report along with the highly anticipated annual “acres” report. This acres report will be the first official indication on how many spring crop acres the U.S. planted in 2017. As this report approaches, we can expect to be subjected to the usual amount of noise as market pundits guess what the report says and where prices will go next.

Tractors are the primary source of work-related injuries on farms; nationally, nearly one-third of all farm work fatalities are tractor related. In recent years, June and July have been the months when most tractor accidents have happened.

At the end of June, we will be losing an integral member of the Penn State Extension Crops team. Dr. Doug Beegle will be retiring after thirty-eight years of service to the College of Agricultural Sciences.

Much of western PA has observed between two and four inches of rain since last week, while much of eastern PA has seen between one-half to one inch of rain during the same period. Because of the wet late Spring/early summer, all of the state has been lifted from abnormally dry or moderate drought status, according to the US Drought Monitor. The best chance for widespread, organized precipitation over the next week will come late this week and into the weekend.

As we proceed through the growing season, there are a few issues surrounding weed control and herbicide use. Below are some items to consider.

June 21, 2017

We have heard that many folks are considering replanting corn and/or soybean following heavy slug damage this spring. Particularly for corn, we thought it would be prudent to remind folks to pay attention to the various genetic, insect-resistant traits and seed-applied treatments that are available because all that is offered is not always necessary.

June 21, 2017

Soybean fields in our program continue to put on new growth and appear to be leaving slug damage behind. From the reports we have this week pest populations remain low, bean leaf beetles are active, but nothing concerning yet. Keep in mind that in their vegetative stages soybeans can tolerate up to 25% defoliation without dropping yield, so do not overreact if you find some feeding damage in your fields. For diseases, none have been reported this week. From last week, the field that may have had the beginnings of Septoria brown spot was a false alarm.

Save the dates for these summer field day events which will provide on-farm research updates and farmer tips for soil health, grazing, and cover crops.

This spring has brought a lot of rain, some of which came down in heavy downpours. The rain is a blessing but can be a curse too.
