Whitefly
While exercising at the Centro de Deportes I came across a Hybiscus plant infested with White (Isuspect Bemisia spp). White fly causes estensive crop
damage around the world and is difficult to control.
Whitefly usually feeds on the undersides of leaves. The white filamentous material is from the Whitefly.

White fly also don't seem to show a preference for certain plants. Once they show, they seem to be everywhere and are a b-tch to even remotely
control. I have them all through my citrus, besides about every other plant we have.

Our hybicus looks like that. We couldn't get rid of the white fly. Mike finally cut the plant all the way back . It came back beautiful but........
It's back with a vengence. How do you get rid of it.k

Try ladybugs.. very effective.. and since a youngster have always like them
Have had very good success with them.. most effective chemical means no longer exists due to the other problems which were found associated with
them...
The ladybugs can be purchased over the counter in the States... and I would imagine that some of the growers down here must use them.. as I have seen
"green houses" over by Primo Tapia.. IPM, (Integrated Pest Mangement) should be in operation down in Mexico too..
http://books.google.com/books?id=tMRtkcTWA1QC&pg=PA275&a...
hope it helps.. they are "pesky" critters...
Just saw corn, posted the same.. will the post as it has a little additional information about the concept and that it is used by large grows too, in
Mexico
But, you absolutely correct Mexicorn.. and was not sure if Home Depot carried them here ... good information... thanks
Also, so really good shots of the little devils.. and they do drive one nuts.. must keep an eye out... every day.. for pest.. another tool .. sticky
cards.. get to see who is out visiting your plants.. id them and develop treatment if necessary... a light soap mix can work also.. just use regular
dish soap and wash the plants well daily.. it can work too.. but prefer the lady bugs.. they just eat them alive...

That is actually the "Super White Fly" of I think Mexican origin that got into the states around 15 years ago...nasty stuff. when I was put in charge
of the greenhouse at the Fort Worth Botanic Garden the place was infested with it. The former greenhouse person had tried biologicals (ie ladybugs)
with little success apparently. Neem Oil didn't do squat, but the dishsoap as wesson mentioned helped a lot---I used it with a hose end sprayer (about
a tblsp/gal) so the bugs would be covered with product AND be physically removed off the plant. However, you must be dutiful---there is no residual
effect with dishsoap so it must be used often! What finally did work for the long haul and was relatively innocuous was a neonicotinoid called
Safari---its a systemic derivative related to nicotine (a wondrous organic insecticide BTW, that's been used for a century under the moniker Black
Leaf 40)---it came in a pellet form so no spraying--just a spoonful for each plant...great stuff! BTW you can make your own "Black leaf 40" by taking
an old cigar and crushing it up into a gallon of water---let it sit overnight and voila! Very effective but no residual effect and DONT use it on any
solanaceaous (tomato family) plants---it can occasionally harbor tobacco mosaic virus.

I was hesitant in calling it Bemisia because of the color. We have alot of the Whitefly in Imperial County and I believe they are Bemisia. At any
rate they are difficult insects to control regardless.

Been a number of years since I worked in the field.. can only guess on how effective current registered pesticides are on these little guy and
others.. critters were hard to hold, even with the heavy duty stuff ... that was used way back in the day of DDT, Lindane etc .. and then the OP's and
other materials.. which were then lost due to other reasons.. not sure how much is left out there for growers.. or are they using "wooden blocks" to
kill them now..

I'm no entomolgist but in working in the Imperial Valley for many years it seems to me that they become a problem for a season or so and then
disappear or at least become less of a problem. It could be that predator insects build up during heavy Whitefly infestation and the predator insects
control them. Eventually the Whitefly returns. As Mexitron mentioned, there are some insecticides that help.

Mexitron is correct. It appears to be Giant Whitefly originally described in Mexico.

Good info wessongroup. Biologicals are definitely a prefered method of control...and they work fine in many situations (eg--conservatories) where
the plants don't have to be perfect looking, or for agricultural situations where the foliage can be less than perfect as long as the fruit is
unaffected. The main problem is that once the predators have eaten the prey there's nothing left so the population eventually falls back into a
typical predator/ prey balance (consider the number of predators of Wildebeest versus the Wildebeest population---they don't make much of a dent). I
guess you can continually re-release biologicals to keep the population high but I don't know how this affects cost. And there's also the dreaded
decollate snail problem--they're great at controlling snails but when the snails are gone they go after the plants Any more thoughts/experience you have on this would be great.

Worked in Ag for 20 plus years, started with Cal Department of Food and Ag.. Pesticide enforcement in 1974 and was concurrently on contract with the
EPA Region IX ... then moved into Financial Industry... in 1992, as I was starving.. Ag does not pay one anything.. it's a trade off they count on...
folks like working in Ag.. and with the issues which develop in producing food and fiber...
Always love working in Ag work.. in the field.. can't say "sweeping fields" in El Centro was a fav... or some of the other.. but over all, just loved
driving around out there after a "cut" of alfalfa ... early in the morning.. working with the aerial applicators and all the others in the Industry..
which is quite large.. still ... helped in the set up of IPM with others in this period, along with the Environmental Monitoring Unit, Worker Health
and Safety, Registration .. and ended working mostly on special projects.. hated to leave .. but the "politics" became just to much to deal with.. for
me, and thought if by going to work for the Ag Chem Industry perhaps could effect greater change.. wrong..
Used to spend time in El Centro.. long ago knew Claude Finnel the old Ag Commissioner and if Steve Birdsall is still alive as Commissioner .. we used
to go pound a few down at the "Buick" .. if that is still there.. also one of the best places I ever had a steak dinner was the old Adobe in Brawley,
which burnt down ... use to stay at the Barbara Worth Country Club when in down
Remember it all fondly... a really great time in my life.. working in Ag.. my favorite job of all I ever worked.. except one .. Air traffic Control,
but that was for totally different reasons.. you for sure were not outside ... always dark, smoky,crowed and really noisy... but, never a dull
moment, except mid shift...
It's all good.. but, really did like the ag work.. was a PCA .. knew a lot of folks from working with the State in all the Counties and State.. from
the Fed side ... and then in working in private industry... which was Regional and National in scope.. not field work.. sad to say.. moved from being
where it was grown to where it was decided how it would be grown...
Used know a lot of folks in the nursery industry too.. Don't know if he is still alive, but the guy that used to take care of all of Heinz Nursery
George Guzman .. we went to school together and took ent together .. along with working on some special projects ... with Hinze and the whole
industries problems which they faced on production in side
Greenhouse production of plants was difficult as the Registrants (Dow, Mobay et al) would not put as much work on small speciality crops as they would
the big money crops ... we were always trying to get Sect. 18's for the folks ... they were being ham strung all the time for effective products in
controlling pests.. plus dealing with Worker Safety issues too
Again it brings back good memories.. of a lot of good people and working on the development of evolving; laws and regulations to address many issues
associated with using hazardous materials in the production for Food and Fiber within the Untied States. while protecting the environment and public
health and safety industries

Wesson--Interesting career! I've threatened to go Ag a couple times but have stayed with landscaping as my bread and butter...better that way, my
artistic side needs the outlet. Got my B.S. at Cal Poly SLO in Botany/Horticulture...took Crop Management with Dr. Hallet, VP of testing at Dow (but
he was still nice enough to teach us about the newly emerging IPM!). Relearned some of the basics when I moved to Texas four years ago and worked at
the botanic garden...was fun but city jobs weren't for me so now I'm back to landscape design/install, which, uh, really sucks in the summer
here...putrid hot! I told my wife I'm working out west next summer, no more of this...let's hope.

Wesson-------the "Buick" is long gone in El Centro, I spent a lot of time there also----but I too ate at the restaurants you mention----and Camachos
out in the country----'The Hacienda' by the airport in Imperial (now in El Centro)------and countless fine restaurants in Mexicali. Lived in El
Centro from 1973 thru 1986, and unlike many, really liked the place, and the Imperial Valley in general----very exciting, and it is the Ag business
that made it that way. I had several friends in the Ag business there, mostly hay. Lots of neat old Farming Families (names I can't seem to bring to
mind) Menville Brothers was one. Danny Robertson was another. Still have friends there that we visit with occasionally------all retired from BLM,
and just stayed. Winters are gorgeous---summers not so much.

Wessongroup-Steve Birdsall recently retired and the new Commissioner is Connie Valenzuela. I also worked in PUE for the County of Imperial and
retired 4+ years ago. I was their Bard/Winterhaven inspector and in fact still work part time for the County inspecting and signing Phytosanitary
Certifications for foreign exports and issuing Certificate of Origin.
I went to Cal Poly ,SLO studying Soil Science under Dr. Logan Carter and went on to the U. of Nevada and continued my studies of Soil Science-obtained
an M.S. in 1969.
I worked for a couple of pesticides mfgs. for about 13 years before I realized I liked govt. work.
My wife and I have a house in Ensenada and Yuma, Az. I like Yuma alot more than Imperial Valley. But, I like Ensenada alot more than either Yuma or
Imperial Valley.

Mexiton.. one group used to work with.. which I liked a lot.. Golf Course Superintends Association..
http://www.gcsaa.org/
To bad I don't know anyone anymore.. think it was 1991 was asked to give a speech at their convention in New Orleans.. quite a treat.. and an
experience.. got all these invites to see all these really cool golf courses all over the United States..
They have a really strong organization for their people, plus I have just love Golf Courses.. they are so beautiful, with all that green grass,
putting greens. and all the rest..
A pretty hard job to get.. and comes with one hell of a lot of pressure..
Have see grown men cry over infestations of "fairy ring" on their greens .... and others things you could not believe just to get things
"looking"good ...
Off topic of off topic..
Once had an experience up in Merced County with "Gallow Farms"
Had one worker die and a whole bunch get sick..
The guy that was running the "grapes" for the ranch was the son-in-law for Mr Gallow.. he was a fashion design major from San Francisco, who had
married into the family... they gave him a job.. take care of the "grapes"...
This guy did not have a clue..
Well, what happened ... he got an infestation of "sphinx moth" and it got away from him.. so he told some works to grab some stuff to spray on the
infestation.. only problem.. wrong product, no instructions to the workers, no safety gear and they were to harvest in three days..
One of the applicators died, right in the yard after coming back from doing the application (the used Phosdrin) .. the other to the hospital (were
able to save him) and then the crop could not be harvested as it carried illegal pesticide residues.. Gallow couldn't lay it down for raisins, could
go for juice and it certainly was not going for table grapes...
We (County Ag Commissioner office) filed with the DA in the County .. and it worked it's way thought the courts.. they guy did not get jail time ..
which in my opinion was not right.. but, politics being what they are ... and Mr Gallow being who he was ... it was not a big surprise ... things like
that happen.. just do..
The fashion designer and the daughter moved back to San Francisco and lived "happily ever after" I guess ... it was after all just one in many
investigations
But, it was always interesting on that job... very interesting.. all the time.. we also worked with Air, Water, Highway Patrol, Fish and Game, OSHA
and spent a lot of time with Fire folks and Highway Patrol... as they were the ones who would have to respond to fires and accidents .. that was
before things had really gotten set up on Placards for storage and trasportation..
Think those poor guys down in Texas that walked up to put that fire out at a trailer, which just happened to have boxes of dynamite inside and were
killed.. seems like 12 or 14 guys got killed.. that really put the pressure on to get things so one could ID them when approaching quickly ... just
had to.. some of that stuff was and still is pretty damn bad.. off topic, but when I saw the responders on 9/11 I had great concern for their exposure
... again.. fire and emergency folks are trained to do one thing... go in.. and help.. very sad for them and there families... really sad.. another
group that don't get enough pay for what they do.. yeah, I know the choose it... but, someone has too.. just that they do it.. and some do it for 30
years.. (and retire.. good for them, even if they drink a bit.. so what.. they deserve it... think I will have one for them this afternoon..)
Thanks for letting me share some of my old war stories.. it was a long time ago.. but still pretty fresh in the brain pan..
Good day to all.. and have a great weekend... but, keep thinking.. and stay alert, one can do both.. I've seen it.. I've done ... would like to do
something right now.. but, can't.. that's just the way it is... they as good as it gets and it ain't bad..
Oh, the other thing.. from that job... man diid I get to know some of the best: coffee shops, restaurants, and some of the best bars in a lot of
places ... woohoo
And Barry we were in the same area at the same time.. left the State in 1986, started in 1974 full time.. worked part time in the summers doning field
work of exclusion and detection.. for a couple of years while in college..

Might have missed it, didn't check all the links.
But the guys around here use WORM CASTINGS....to kill and controll the white fly.

I have had luck using a combination of Ivory liquid and sticky traps. I painted plastic disposable plates yellow and covered them with Tanglefoot to
make the traps.
