Several wheat fields in Kentucky are now at the anthesis stage (Feekes 10.51, “flowering”) or fast approaching it. Anthesis is a critical time, as wheat becomes susceptible to infection by Fusarium graminearum, the primary causal agent of Fusarium head blight

The growing season is usually defined as the days from the last freeze (32°F) in the spring to the first freeze (32°F) in the fall. Since climate change is increasing air temperature, the growing season is getting longer.

Across Kentucky almost all of the wheat crop has jointed (Feekes 6) and much of it has developed at least two nodes (Feekes 7). When temperatures dropped into the teens and low 20’s (°F) overnight March 19 (Table 1), we once again find ourselves asking the question: Will the low temperatures a couple of nights ago damage this year’s wheat crop?

Several aphid species are key pests in small grains (wheat, barley, and cereal rye) in Kentucky for their role as vectors of the Barley Yellow Dwarf Virus (BYDV). Among them, the Bird cherry-oat and English grain aphids overwinter as nymphs or adults, and they can start feeding and potentially transmit viruses when temperatures are above 45º F.

This is the time of the year when contest-winning corn and soybean yields are announced. Some of the winners set records for the highest yield ever – yields that can be as much as 3 or 4 times the average U.S. yield. Yields that high bring to mind the silver bullet syndrome…

Both corn and soybean finished strong across Kentucky despite lower total rainfall amounts across most of the state. The 2023 Kentucky corn crop is estimated by the Kentucky Office of the United States Department of Agriculture National Agricultural Statistics Service (USDA-NASS) at 183 bushels per acre, up 17% from 2022, making the second largest corn crop on record.

Biodiesel and renewable diesel made from vegetable oils can replace petroleum diesel in long-haul trucks and shipping. Biodiesel blended with petroleum diesel and renewable diesel are ‘drop-in fuels’ that can be used without modifications of diesel engines.

One basic soil health concept is that of plant diversity – a diversity of plant species grown in your fields will benefit soil health. Crop rotation is a well applied example of that soil health concept.
