How Much To Pay For Cow/Heifer?

We had a great meeting and heard great presentations at the Thomas County Beef Cattle Update on Thursday by UGA Extension Specialist Dr. Jacob Segers and Dr. Curt Lacy.

I wanted to share the UGA Replacement Female Calculator link from Dr. Lacy’s presentation. You can find it on the Southeast Cattle Advisor’s website, then click on “Decision Aids.” That takes you to the UGA Econ page, then scroll down to” UGA Replacement Female Calculator.”


Beef Cattle Summary from Dr. Lacy:

  • Expect less beef and more meat production in 2015
  • Higher prices
  • Higher profits
  • More heifer retention

Barley Yellow Dwarf Virus?


In our forage crops, we started with bad stands from dry weather at planting . Cold weather in early November and after Christmas has not helped in growth rate. Barley Yellow Dwarf Virus is vectored by aphids and could also be causing some of our issues. UGA Extension Forage Scientist Dr. Dennis Hancock says reports of BYD are coming in from South GA.

In some oats, I noticed an abundance of aphids last week. We’re used to counting aphids for grain crops, but we have to also think about forage crop management too. BYDV can severely damage wheat and barley, but oats are more susceptible. UGA Extension Grain Entomologist Dr. David Buntin says, “The best treatment time usually is at full-tiller stage in early to mid-February. But, scout fields for aphids at 25 – 35 days after planting and during warm periods in January.” Especially if these fields were planted earlier, which Dr. Buntin says is more likely to get BYD. Could we may be seeing issues with BYDV earlier than normal? Something we need to keep in mind.

Also, oats are also more susceptible to cold, and nutrient symptoms may look similar to BYD. When we have cooler temperatures, this slows P movement into the root and we’ll see a purplish color which is textbook phosphorus deficiency. Plant roots have to be in direct contact with P for uptake. This is called “root interception.” Cold temperatures slow the growth of roots and we see this deficiency.  Nutrient take up is different in nitrogen, called “mass flow”.  This is because N is mostly taken up as nitrate in water.

BYD Management

The virus is present in most fields throughout the winter and once we get it, there is nothing that can be done. Here is an excerpt from Dr. Buntin about management of BYD:

“Systemic seed treatments, imidacloprid, thiamethoxam, and clothianidin, are available for controlling aphids in the fall and winter and may reduce infection rates of BYD. These seed treatments are more effective in the northern half of the seed treatments have been inconsistent in control and are not recommended for routine use. A single, well-timed insecticide application of the insecticide lambda cyhalothrin, or gamma cyhalothrin also can control aphids, reduce the incidence of BYD and increase yields… A lambda cyhalothrin or gamma cyhalothrin treatment at full tiller can be applied with top-dress nitrogen. OP insecticides, such as dimethoate and methyl parathion, also will control aphids but are not effective in preventing barley yellow dwarf infection.

Planting date is the single most important management practice, with early plantings generally have greater aphid numbers and greater BYD incidence than late plantings.”

Generic Base

Seminole Crop E News

There has been a lot of confusion surrounding the new farm bill and Generic Base (Old Cotton Base).  Early County Agent, Brian Creswell, has some advice that may clear this up some.

All crops that will be planted in 2015 will be assigned to generic base first. You do not get to designate what you want on your generic base. It will assigned by taking the total number of acres you plant of each crop and dividing that by the total numbers of acres you planted to give you a percentage of that crop. That percentage will be multiplied by your generic base acres and that many acres of the crop will be applied to generic base. Know that it’s clear as mud the following example may clear things up.

In this example it shows the total number of acres planted in a covered commodity which is 175 and…
