Which wheat fields are most likely to be infested with Hessian fly in the fall? It depends on residue management, variety, planting date, the presence of nearby volunteer wheat, the use of insecticide seed treatments, and crop rotation. Continue reading “Factors That Influence Hessian Fly Fall Infestations”
Coming into spring is a good time to evaluate and perform maintenance on terraces if fields are in wheat stubble, especially since it has been dry lately this year. In Kansas, over 9 million acres of land is protected by more than 290,000 miles of terraces, making Kansas No. 2 in the U.S. for this soil and water conservation practice. To accomplish their purpose for erosion control and water savings, terraces must have adequate capacity, ridge height and channel width. Continue reading “Terraces Evaluations”
Where volunteer wheat has emerged, producers should consider beginning control measures soon, if possible, rather than waiting until closer to wheat planting time. This is especially important on fields where wheat was hailed out and volunteer wheat emerged at the time of harvest, or shortly afterward. Continue reading “Mid-Summer Control of Volunteer Wheat”
The severe problems wheat producers had with wheat streak mosaic virus this year can be traced back in most cases to a lack of control of volunteer wheat – especially the volunteer wheat that got started early after widespread hail damage to wheat just before harvest in 2016. It is important to keep that from happening again. Where wheat has been hailed out this year, volunteer wheat control should start immediately. Continue reading “Wheat Streak Mosaic”
The 2017 In-Depth Kansas State Diagnostic Wheat School, will occur in the Experiment Field in Hutchinson on May 10-11.
This will help you in depth in all aspects of weed control, soil fertility, disease management, insects and summer cover crops. Registration is NOT needed.
Note: This is a 1.5 day event where CCA/CEU credits will be available. Continue reading “2017 In-Depth Wheat Diagnostic School Speaker Schedule”
Temperatures over the weekend of April 22-23 dropped below freezing and into the lower 30’s for most of the state. In a few specific locations in southwest Kansas, temperatures were in the upper 20’s in the early morning of April 23, and were well below 32F for as long as 7.3 hours. In low areas of the fields, temperatures will typically be lower than the officially recorded temperatures.
The effects of a freeze event to the wheat crop will depend on Continue reading “Wheat Freeze Update”
The wheat crop continues to develop at a fast pace across the state. The most advanced fields in far southeast corner of the state are between boot and flowering, and the majority of the region is already at or past flag leaf emergence. Parts of south central Kansas and the northern-most counties in southeast Kansas are mostly now at flag leaf emergence or at boot. Wheat in central Kansas and in fields that emerged last fall in southwest Kansas are past the second node and approaching flag leaf emergence. Northern Kansas and northwest Kansas have the majority of the fields now at jointing growth, or just past it.
The major issues being faced across Kansas in the current wheat crop involve viral diseases (mostly wheat streak mosaic in western Kansas and barley yellow dwarf in central Kansas), stripe rust, and nitrogen and sulfur deficiencies which are still showing up in many Kansas wheat fields.
