8th International Hazelnut Conference - Temuco, Chile

For those of you who wonder what a Research Associate does... one noteworthy activity I engaged in this early spring was to attend the Eighth International Hazelnut Conference in Temuco, Chile.  In addition to making and renewing contacts in the world of hazelnuts, I presented a poster on the preliminary results of my research on vegetative propagation.  (You can see the full poster at the end of this posting.) Interestingly, once I got there I found they had tagged on the words "europeo Avellano" to the conference publicity.  This was indicative of the focus of the majority of the presentations. With this blog I hope to share some of the interesting bits of information I gleaned from the proceedings.

Why Chile for a hazelnut conference you might be asking.... (this blog will be the first of a number...)

• Chilean aspirations  Chilean growers are intending to become major growers of European hazel and surpass Oregon, Spain, and Italy in production.  Currently they have about 15,000Ha (37,000A) in cultivation and they are adding about 1,000 Ha annually. Most of these plantations are not yet bearing fruit. They do not have Easten Filbert Blight in Chile and feel they are geographically protected from its introduction.  Consistent with this - they are planting large acreages of EFB-susceptible clones such as 'Barcelona' and 'Tonda di Giffoni'.  Some of the newer Oregon State University introductions are also being planted on a smaller scale - thanks to a Chilean tissue culture industry.  These cultivars have major gene resistance to EFB.

A stumbling block or two are being encountered along the way...

• Chilean challenge  A beetle of the cucurlio type (Aegorhinus superciliosus), commonly found in Chilean Nothofagus forests, has found the non-native hazelnut bushes to its liking.  The insect larvae feed below the bark on the crown tissue.  As the larvae grows to 2cm in length it does serious, often lethal, damage to the vascular tissues. 

• Some innovative work is being done to isolate soil fungi that have been found to be effective controls of the insect in laboratory tests.  In order for this to work effectively, however, the beetle needs to be precisely identified (there are some look-alikes) and the complex life history carefully attended to to actually deliver the fungi to the insects in field situations.  Unlike systemically translocated chemical insecticides (e.g., Marathon, etc.), the fungal spores or hyphal suspensions need to actually contact the insects.  Thus, knowing what time of day and under what temperature and light conditions the beetles exit the plant are critical.  Some poor grad student is probably camped out in a hazel orchard right now with a flash light!

For August 18: Field Day Poem

Actual details coming in the next couple of days, but here's your first reminder that our annual field day is on August 18. In poetic form, by our secretary Sara West:

You're invited to the Annual Badgersett Field Day
A chance to come learn and play
With friends old and new
And bring the family too!

There will be tours of the farm
That will cause little harm
We'll have plants available
Have lunch at a picnic table

So come one and come all
To the kickoff event of the fall
We know it's a bit early
But we need to beat the squirrelly's

Finally, a catalog update!

If you're on our catalog email list, you should already have seen this little note from orders@badgersett.com. If you want us to add you to the list, just send an email to that address! And, so you don't have to go looking any further, here is a link to the YouTube full preview of the 2011 Short Course introductory talk.

Hello Folks,

For the first time in six years, we've updated our plant catalog! And in addition, we once again offer other products for order on the web. This includes the 2011 SHORT COURSE DVD-ROM, which I know many of you have been waiting for. This crazy weather may be too hot and dry for some of you to plant, but now is a great time to get your order in for 2013 so you can be close to the front of the shipping queue come next May. If you're in a place where it is less extreme, or you have no problem getting enough water on, we do have quite a few plants available– the availability notices on the catalog pages are now current.

Our chestnuts are the most cold-and-dry adapted available. Now includes SELECT PARENT chestnuts so you can be choosier, as well as JUST PLAIN CHESTNUTS so you don't have to choose at all.

HICKORIES: Now available as regular standard tubelings. http://badgersett.com/plants/orderhickories.html

Exteme conditions-

A few more points on keeping newly planted tubelings alive in extreme conditions.

Our regular planting instructions strive to be complete; but the reality is, the current record-breaking heat and drought are outside anything you could call "normal".  We do have some additional experience that can help you in this situation.

A.  Water deeply.  If you are only able to supply enough water to get the ground wet down 2-3"; you might be better off not watering at all.  Because: hazels normally grow roots very near, or even "in" the ground surface.  Particularly when newly planted, they have limited resources to work with; if you are only watering shallowly, they will be encouraged to grow mostly shallow roots- following where the water is.  They may not have energy enough to also grow deep roots.  So- when it gets dry again- they will be stressed, again.

Try to deliver enough water so that the ground becomes wet at least 6" deep; 8" is better.  This will encourage deep root growth- and down below 8" there will still likely be water available in the soil; and the roots will continue growing deeper.

B.  DO NOT PULL WEEDS near your newly planted tubelings.  Their roots are intertwined, and you will destroy some of the roots of the tubeling; it may not be able to recover in this extreme situation.  You can cut the weeds off; but don't pull them.

C.  NEVER HOE around new tubelings- the damage to their roots can be drastic.

D.  DO NOT suddenly remove all weed cover, if the tubeling has been buried- it will burn up.  If weed cover has become extensive, we cut off all weeds to the NE of the tubeling, leaving most of the weed shade to the south, west, and overhead.  A little shade won't slow the tubeling down at all; and a little protection from drying winds and sun may actually help.

E.  DO NOT let the tubelings remain totally buried in weeds - not only will total shade slow them; but the deep cover greatly encourages insects, which are safe from birds there.  In particular, young hazels may be skeletonized by grasshopper nymphs - if buried in grass.  Opening up just the NE side will drastically decrease grasshopper attacks.

F.  If you feel you cannot keep up with watering in these drastic conditions; consider a) covering the tubelings with a hay/straw "hat", just during the extremes, quickly removed when the weather breaks; or even b) abandoning some of the planting, and concentrating on saving a portion of it- whatever you can actually deliver enough water to.

Even in the worst conditions- there are tactics that should prevent total loss.

G.  CALL US - if you need advice.  We'll try to help; and there are a few more tricks in our bag.

HEAT = WATER ?

We're spending a great deal of time right now watering - but only hazels (or other) that were planted THIS year.  Anything planted last year, for us, is not stressed - yet.  Though it might be.  Anything planted 2 years ago; we consider safe and not in need of supplemental water except perhaps in extreme circumstances (or on sandy soils, maybe).

But; yes; this kind of extreme heat and dry weather can kill tubelings planted this year; they're still tiny. Get them watered if you have ANY doubts about it.

Meanwhile:

Our friend Hank Roberts made this comment on the last post:

"I know you're too busy to be blogging these days, just thinking about y'all while watching the weather. I know a tiny bit about heat stress on corn and soy (both the limits during critical periods and the overall degree days, I think?), but nothing at all about what factors combine to affect success with your woody crops."

Yah, busy, but it takes a while for the pickup water tank to fill; 450 gallons-

We're expecting this to be a year when the hazel crop really shines- so far, the hazel crop is in no danger at all; not even stressed; while the prices of corn and soybeans go up every day it doesn't rain-

Take a look here to get an excellent idea of how heat and drought affect the corn crop: and note that's from August of last year.  The corn this year; having been planted earlier, may actually be more at risk.

Very quickly; the hazels share almost none of those risks.  The crop pollinated and the nuts were set in March and April.  Currently they are sizing, and filling.  Yes, it's known that some hazels may suffer decreased size, or even abort the embryo, if exposed to high heat at the wrong time.  But- our hybrids include genetics that appear to be immune to those problems.  So far.  Hazels are C3 plants, not C4 like corn- which we can and do argue is a great advantage (twice the Growing Degree Days in the same locations); but precise effects of heat are not well studied.

What is known about heat stress in hazels is only on a cultivar by cultivar basis- and our populations of diverse hybrids confound the desire to make broad sweeping statements.

One thing for growers to do- keep an eye on your hazels!  Those that come through this summer with good solid crops- are going to be important for future of food, as the climate warms.
