My experience has been that the yellow sticky traps work
fairly well to collect whiteflies, but cabbage looper moth
populations are not controlled by sticky traps. The best
solution to cabbage moth caterpillars that I have used is
Bt. After a brief outbreak last year, I have not had a
significant resurgence of the moths after a brief period of
application with Bt. True, I had to do several
applications, but the moths are now essentially gone from
the greenhouse- I see 1 or 2 caterpillars now and then, but
they are swiftly removed by hand, or spot sprayed with Bt.
No big deal.

Howdy.
Any one out there ever used Actinovate products in the greenhouse?
Ken, this might help address your yellow leaf problem. That and keeping
your water well oxygenated at all times and your beds (and thus your roots)
not too water logged
Folks from Idaho State University isolated a strain of Streptomyces lydicus
(var. WYEC 108). The folks at Natural Industries now markets a product they
call Actinovate, which is the microbe in question- an actinomycetes critter
with "siderophores", an enzyme produced by S. lydicus which they claim is
responsible for chelating minerals and making them available to our plants.
I know that S. lydicus is not unique in possessing siderophores- these folks
just happen to like this critter because it also seems to impart plant
protection from soil borne pathogens and other problems.....This may go
toward explaining our aquaponic plants' uptake of iron and other nutrient
availability issues that we can see in aquaponic systems (or soil systems
for that matter) even at pH ranges that are outside the "theoretically
optimum" range for the plants. Siderophores and humic acids are the little
extracellular polyelectrolytes that shuttle nutrients from one species of
soil dwelling organism to another, it would seem.
Check them out at http://www.naturalindustries.com.
Let me know what y'all think. I have not tried this myself. Just curious.
Ted.

Subject: what to grow in Costa Rica?
From: Jose Pelleya
Date: Sat, 08 May 1999 09:38:58 -0600
Hi:
Thanks for the advice.
I'd certainly like to make choices that are market driven and logical.
There are advantages to growing here: good growing weather year-round, lots
of water 7-8 months out of the year (and readily available the rest), cheap
labor, and variety.
I like the idea of different products, nothing that's now being exported
from here, perhaps value-added or gourmet, like sun-dried tomatoes, smoked
vegetables, fruit preserves or dried fruit, maybe baby vegetables, unusual
salad items.
The local market is fed by local farmers, the only niche for expensive or
unusual products would be the tourist hotels, cruise ships, and the small
market of wealthy people and foreigners.
Costa Rica has a fairly small population, somewhere around 3.5 million, and
about 800,000 tourists a year, some of which are surfers and backpackers
who never reach the big hotels. Of the permanent population, maybe 10% can
afford arugula or chard or anything like that. The majority eat what grows
traditionally: onions, green peppers, tomatoes, lots of roots and gourds,
lots of fruit.
There is a market for offseason vegetables, like tomatoes in the summer and
fall here go up. Now, there's tomatoes everywhere at 100 Colones the kilo
(2.5 pounds for 30 cents), but prices double or triple when the rains
start, because tomatoes can't take water on their foliage, hence a hydro
operation under roof can fill that gap.
There's a market here for Tilapia fingerlings, since there's a big move to
help the small farmer dedicate some land to small-scale fish production,
and the experimentasl spations which supply the fingerlings can't keep up
with the demand. Fingerlings here sell for about 10-15 cents, after 30 day
sex reversal process is finished.
Any advice from out there?
Jose

V:
How about trading them for veggies?
Or make a nice smoker and smoke them suckers.
I always had trouble rolling them up in the paper to smoke them.
Re integrated farming: is that the same as permaculture?? Which by the way,
is what small farmers have been doing for years.
I find it amusing and interesting that the more we learn about new things,
the more we find out that what people were doing 400 years ago is now seen
as the "new wave": organic farming, multi-crop versus mono-crop, natural
pesticides, integrated pest management.

driana:
You're hired, when can you start?
I, too, worry about the mortgage. That's why I'd rather have private
capital as partners/investors.
What would be the highest and best use of that greenhouse?
I favor a diversified crop (flowers, culinary herbs, medicinal plants,
unusual vegetables and fruits, aquaponics) rather than a mono-crop, and
make it interesting enough for visitors to pay to see it, and maybe stay
overnight, give short courses, etc.
What do you think? I may be going to FL for a visit in the next couple of
months, and I believe you're in Sarasota, no? Maybe I'll drop by and see
what you've got there.

Jose,
I hear that the US flower market is quite saturated with low-cost
product from Colombia and Ecuador. If you have good cruise ship
traffic, check with them for interest in salad mix, tomatoes and herbs
is a good possibility because you can charge $US. One other area to
look into is the market for root stock for roses. The root stock would
be sold to rose farmers.
Send me an e-mail when you get your travel plans together and I'd be
happy to show you my set-up.
Ciao, Adriana

Ah yes, James, thanks for the reminder. That is why I specifically
mentioned that certain species of Streptomycetes are something to control
with high water quality maintenance- for the sake of preventing off flavors
in the fish crop- in my draft organic aquaculture standards.
Hmm.. I wonder, though......just as all blue green algae do not produce
geosimin- a compound produced by a few species of blue green algae which is
responsible for off flavor in fish- similarly I would think that not all
actinomycetes would create off flavor in fish- especially if they are not
the only microorganisms present in the biofilter. Furthermore, the species
of blue greens that produce geosimin may not exude it all the time, but only
under certain growth conditions related to nutrients or water quality.....
Since there are so many species of Actinomycetes naturally occuring in the
soil- this is a broad group of organisms, by the way, perhaps only a few can
cause this problem in aquaculture.....This species of S. lydicus might or
might not produce off flavor compounds, but I just don't know the answer to
that question. Just curious to know if anyone has dabbled with it. Sounds
like a small scale pilot project should be attempted before this bug is
liberally broadcast about the aquaponics greenhouse, though, eh?
Ted.

Ted, Rather than micromanage microorganisms, there should just be a purge
precedure at every aquaponic facility to assure high quality. A 3 to 4-day
dip in fresh water should do it. The golden rule of aquaculture is DO NOT
SELL BAD TASTING FISH. We did this once and it wasn't very pretty. Being
overexuberant with the size of our aquaponic tilapia, we invited the guy
from the fish market to view them and then decided to give him about 40 lbs.
of free fish for a sales trial. They sold all right, but the next day he was
greeted with angry customers demanding their money back. So rather than
receiving heaps of gratitude from the fish guy, we were cussed out. Jim R.

Oh boy. Uwe had to ask. Gee, let me think here. Was it Anabaena
flos-aquae? My brain is fried right now from struggling in the heat of the
day to put the shade cloth back up on the green house. Next time
around...automated, computer controlled robotics for the shade cloth!
O.K......Geosmin is the compound which causes the earthy, musty flavor that
catfish can sometimes pick up in ponds with this blue green alga in it.
(Sorry Mr. Jim Searcy..not just catfish, but any other critter, I reckon...)
Another compound that is produced by some of the blue greens is.....O.K. I
am pulling this out of the sludge pit of old biochemistry memories...is it
Bornane?..IsoBornane?...Boron?....Borneo?...Ernest
Borgnine?...Nope...Sorry....Nevermind..... It's hopelessly lost or the brain
file got corrupted......Anyway, these are not good for fish sales as Jim R
pointed out.
You youngin's can go look it up on the Internet. Gotta run.
