Use management objectives to determine rye cover crop seeding rates.
While western parts of the state have seen upwards of 2-3 inches of rain over the past week, much of eastern PA has remained relatively dry since last Wednesday. The upcoming week will be relatively dry and seasonal as meteorological fall begins on Thursday.
Now is the time to think about controlling summer annual weeds, prior to seed set, in certain cropping systems.
Producers and crop scouts are reporting note-worthy worm infestations in field and sweet corn crops across the state that are most likely corn earworm, but another worm pest is possibly expanding its range in the northeast US which requires that we take a second look at these situations to confirm what we are seeing.
Corn silage dry down is hastening across the state, causing the need for farmers to monitor moisture levels so the optimum dry matter is achieved for ensiling and helping to ensure optimum forage quality.
A three-year NESARE-funded on-farm project demonstrates improved forage inventories and soil quality on two Pennsylvania farms.
Plant pathologists from all the major corn-growing regions of North America have joined forces to bring you some new resources!
Combines are one mechanism for the spread of herbicide-resistant seeds from one field to another; thorough cleaning and knowledge of the combine’s prior use can prevent the introduction of new herbicide-resistant weeds to your fields.
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.
