California Alfalfa Hit With Stem Nematodes
by Fae Holin
Managing Editor, Hay & Forage Grower

It wasn't a pleasure trip from his Idaho base to California last week, says Don Miller, forage breeder with Producer's Choice Seed. Miller spent several days inspecting alfalfa stem nematode damage in alfalfa fields. Some fields have lost half their crop, he believes.

But the damage, found in the Sacramento and San Joaquin Valleys, usually affects first-cutting alfalfa only, says Dan Putnam, University of California Extension forage specialist. “We've seen fields that looked absolutely devastated and dead, but they actually do come back in the second cutting. However, some fields this year are so badly affected, they may not come back very well.”

“It's a question of number of plants. If there were enough plants that were killed, then you would consider some other options, like overseeding with grass or plowing the crop under. But if you still have a halfway decent stand that produces maybe not 100% of yield but 80% or 90%, most of you will want to keep it in,” he says.

Yet the stem nematode problem appears to be increasing in the state. “Is this something that is just two bad years out of 10 or 20 or is it something that we're going to see more of as time goes on? My thought is, it may be the latter,” Putnam says.

“That nematode is as bad as I've ever seen,” agrees Miller. “Part of the problem down here is that they reuse irrigation water, and nematodes live in the water or on the equipment.” Growers who run tailwater from one field to another, or move a windrower or swather from field to field, help spread the pest.

Few chemical control options are available, and planting stem nematode-resistant alfalfa varieties gives the best control, Miller says. Yet resistant lines now available may not be resistant enough. For more of Miller's and Putnam's comments on the stem nematode outbreak, and what Putnam thinks alfalfa breeding companies should do about it, read “Stem Nematodes Strike California Alfalfa – Again.”

Wisconsin Dairy Hay Supply Tight
Prices for top-quality dairy hay have been pushing up steadily throughout the winter at the twice-monthly quality-tested hay auctions conducted by the Dodge County Forage Council (DCFC) in Beaver Dam, WI.

“Quality hay is almost impossible to find right now, not just in Wisconsin but in neighboring states as well,” says Dan Ritger, auctioneer at the Beaver Dam Auction Market where the DCFC sales are held. “There just wasn’t a lot of good-quality hay made last summer.”

Two lots of 3 x 3 x 8’ alfalfa square bales, RFV of 116, brought a price of $200/ton at the sale last Tuesday, March 16. At the two previous DCFC sales, the same kind of hay, brought in by the same Canadian supplier, sold for $150-180/ton. “We’re seeing 30-40 buyers at each sale,” says Ritger. “There’s a lot of interest. People need the hay.”

The final DCFC auction of the season will take place on April 6, starting at 1 p.m. For more information, contact Ritger at 414-333-8625 or Dodge County Extension soils and crop agent Matt Hanson at 920-386-3790. See previous sale results.




Assess Spring Planting Risk
There’s still plenty of time to plant hay or pasture crops this spring. But extended periods of wet weather and the potential for flooding may make it worthwhile for some growers to wait until late summer to put their crops into the ground, says Iowa State University Extension forage specialist Steve Barnhart.

In most of Iowa, forage stands can successfully be planted into the first 10-14 days of May, Barnhart notes. “The increasingly dry and hot soil surfaces in late May and June increase the risk that the small forage seedlings do not establish. If conditions turn normal or hotter and drier than normal, the risk of late-planted forage seeding failures increases. If late May and early June conditions remain cooler and wetter than normal, then later-than-desired spring forage seedings may survive very well.”

He adds that delaying planting can also increase vulnerability to erosion and weed competition. “Keep cereal companion-crop planting rates to half of a full seeding rate or less, and mow or clip new seedings several times during the early seedling development months to allow light to reach small developing legume and grass seedlings.”

If you opt to wait on planting until late summer, you’ll want to provide seedlings an establishment period of six to eight weeks before the first killing freeze of fall. Existing soil moisture and the prospect for average or better rainfall will influence success rates. “The risk of stand failure is high if seed is planted in dry soil, and rainfall patterns for the remainder of the fall season are erratic,” says Barnhart.

You’ll also want to keep in mind that seed is perishable. “Germination declines over extended storage time and declines faster if seed storage conditions are warm and in high humidity,” he says. “Certainly try to store carry-over seed in a cool, dry place. Even better, try to arrange for storage in a more desirable seed storage facility.”

If you have concerns about the viability of carry-over forage seed, he advises having a germination test done before planting and adjusting sowing rates to compensate for any germination percentage losses.

Get The Most From Samples
Going to all the trouble of sending forage samples to a reputable lab won’t do you a lot of good if you’re not sampling correctly to start with, says University of California Extension forage specialist Dan Putnam. Here’s his checklist of good sampling practices:

  • Use a very sharp coring device with a 3/8-3/4” diameter to cut through the hay.
  • Insert the device into the butt ends of bales between the ties, not the sides.
  • Gather random samples. Every fourth or fifth bale is fine, but sample the entire stack.
  • Get at least 20 cores and mix them.
  • Gather a half-pound sample.
  • Do not leave samples on the truck dashboard in the hot sun.
  • Only use a certified lab.
  • Ask the lab to grind the entire sample.
  • Make sure you can certify the hay sample using a free online test.
The National Forage Testing Association offers a list of certified labs and more information.

“Unfortunately, most people who are critical of alfalfa look only at water consumption and are clueless when it comes to other benefits.” – Aaron Kiess, executive director of the California Alfalfa & Forage Association, responding to a recent column in a California daily newspaper “slamming” the amount of water used in alfalfa production. Source: Western Farm Press.

“While I understand that certain thresholds must be set by the Farm Service Agency (FSA) and met by the producers, I am concerned that valuation calculations set on hay and forage are too high.” – U.S. Sen. Chuck Grassley (R-IA) in a letter to Ag Secretary Tom Vilsack. Grassley wants USDA to adjust Supplemental Revenue Assistance Payments (SURE) “to more equitably treat producers with hay and forage.” See “Disaster Program Unfair For Iowa Hay, Forage Growers?”

“The government has an obligation to protect farmers from the interruption of markets and, by so doing, protect the economic interests of all Canadians.” – Maureen Bostock, spokesperson for Canada’s National Farmers Union, expressing support for a bill now being considered by the Canadian Parliament. The measure would require an analysis of potential harm to export markets before the sale of any new genetically engineered seeds is permitted in the country. Source: New Democratic Party of Canada.

“Whether it’s the dairy industry, the general economy or the international economy, I really see more opportunity in the next 10 years than there has been in the past 30 years. But there’s also going to be more opportunity for failure.” – Ag economist David Kohl speaking at the annual meeting of the Professional Dairy Producers of Wisconsin last week in Madison. More than 1,300 people attended the two-day meeting.

State Reports: Kentucky, Texas
Kentucky
Spring has been a little slow in arriving throughout the state, says University of Kentucky Extension hay marketing specialist Tom Keene. “It’s one of the worst winters we’ve had in 30 years. Everybody has had enough of the cold, snow and mud.”

Typically, at this time of year, grass has greened up to the point where livestock producers can turn stock out on pastures. “We’re getting there,” says Keene. “But we’re probably still a week to 10 days behind.”

On the upside for hay growers, the harsh winter has played a role in nibbling away at overall hay supplies. “We’ll still have some carryover, but it won’t be anywhere near as much as we thought we were going to have heading into winter. We fed a lot of hay this winter.”

One result: Hay prices bounced back slightly in the last several months. “At the start of the season, prices were 30-50% lower than they had been a year earlier,” says Keene. “They’ve now recovered some, but they’re certainly not back to the levels we saw last winter.”

Keene can be reached at 859-257-3144 or tom.keene@uky.edu.

Texas
The hay cupboards are bare in East Texas, reports Aaron Low, Texas A&M AgriLife Extension agent in Cherokee County. “There’s absolutely no hay to be found anywhere. People are down to the point where they’re feeding four-year-old hay that has been sitting outside. It’s stuff that probably should have been burned a long time ago.”

A long, cold winter that caught many livestock producers off guard played a major role in the supply shortfall. “We had a dry summer,” he says. “We didn’t get much rain from mid-April through mid-July. On the other hand, many people were able to put up good first and third crops. A lot of the surplus was sold down in South Texas where they had a severe drought. The way the winter turned out, a lot of people probably regret doing that now.”

On the upside, Low says, a near-term forecast for warm weather over the next few weeks should take pressure off hay supplies. “Pastures are just starting to green up. I think we’ve seen the worst of it.”

Looking into the season, Low expects many growers will leave hay acres in production in 2010. “With the hay supply as low as it is, I think a lot of people will be cutting as much hay as they can this year. Fertilizer prices have come down quite a ways, too. That will be enticing to some people as well.”
