Wheat Grower Update 3.3.22
Our growing wheat crop should be jointing now or in the next 7 days.
Two points to consider:
- If you are splitting your nitrogen applications as discussed in our High Yield Wheat Management Considerations, you are approaching the target deadline to get your last application out, just before jointing.
- A recap of Nitrogen and Sulfur applications below:
- Apply for the wheat crop year a total of 100 to 120 lbs. of nitrogen per acre plus a total of 20 lbs. of sulfur per acre.
- Three applications are best but less will work:
- 25 to 45 lbs. of nitrogen per acre at planting (behind cotton 40 to 45 lbs. of nitrogen)
- 50 to 70 lbs. of nitrogen per acre 15 to 30 days prior to jointing (approx. Jan 15th to Feb 10th)
- 30 to 40 lbs. of nitrogen per acre at first joint stage (approx. March 1st-20th)
- This recommended application is for planting behind peanuts. High residue crops like cotton/corn may require more nitrogen. Some varieties may also need less nitrogen to make the same yields, so please do not over apply N.
- This warmer weather usually brings on concerns for spikes in aphid population so fields should be scouted to minimize occurrences of Barley Yellow Dwarf. Current UGA treatment threshold for this stage of wheat is 6ft/row. If the treatment threshold is met, you may want to consider a separate foliar application as outlined below.
A well-timed insecticide application of a persistent pyrethroid insecticide such as lambda cyhalothrin (Warrior, Karate, Lambda, Silencer, others) will kill aphids and reduce the occurrence of BYD and in turn increase yields.
*More Info about Flag leaf fungicide application to follow.
*More information about FHB Control and Timing of application will be published once we get closer to that point in the growing season*
