Those are some really great photos of one very ugly infestation!

Wessongroup, sounds like you were working in the Imperial Valley about the time John was doing his Geography Master's Thesis on the Salton Sea area----one of the things he talks in the thesis is all of the empty nasty insecticide containers that the farmers around there used to just throw into those "pristine"rivers---the New and the Alamo. :biggrin:

Again, those are just really good photos-----now I hope the next ones will be of that beautiful flower with nice green leaves!

Yes, I have seen many growers using yellow tape around production agricultural fields to control white fly, I have also heard of using detergent but it is expensive and does not last long. That kind of treatment is best used in small areas-gardens.
There are some pesticides that work. I remember Admire (Bayer Ag.) being used but I believe it is tough on bees. Bee Colony Collapse that has been discussed widely is thought, in part, to be caused by pesticides.
We had a horrible problem years ago with White Fly (Bemisia) in Imperial County but to my knowledge it is under control.
One thing for certain the battle will contiue!!

DianaT... a really funny one... was invited to a BBQ... Santa Maria style ... with tri-tip, fresh corn sweet corn (also BBQed) with super beans, rice and salad, home made tortilla's made on the spot ... and of course refreshments..

But, the funny thing.. the guys that were BBQing the meat were using old pesticide 55's which had been cut in have... the drums still had labels on them ... they had held Phosdrin...

Mentioned to the guys, maybe they should maybe not use them to cook food.. "hell we use the Phosdrin to start fires... the product had a xylene carrier.. xylene would keep from burning the "plant" while keeping the AI in suspension for application.. and would "burn off" quickly once applied.. and did work for a fire starter... I ate it... didn't die and I'm still alive.. so, guess they were maybe correct..... "hell, there ain't going to be anything to hurt you left".. not the kind of scientific studies I would like to bet the ranch on... but, with 40-50 folks and there kids eating too.. who am I to say "stop"..

Farmers in that period of time were just a real treat to try and get to recognize that many of their practices "using agricultural chemicals" where in fact not a really good idea...

Farmers are the salt of the earth.. but, can present some degree of problems in trying to get them to do things different.. and when your trying on THEIR property.. oh boy... all good people .... just really did not understand how something they had been doing for a long while and which had not killed them, could possibly, kill anyone... as it had not killed them.. and they had been working with the materials themselves ..... in some cases all their lives.. so to try and get them to see any reason to change was a very hard one...

And for a new young guy just out of college.. with ideas like "protect the environmental and public health" well we were a a long ways apart... except on things like food and booze... and being resonable in getting them to understand the need to change. as these folks did not, do not ... want to do something wrong.. they are and were good people.. working hard to produce food and fiber for all of us.. even all over the world..

As a lot of grain, was inspected and classified right there in "Imperial" by the State of California and the USDA for export to all over the world.. used to go by rail to San Diego.. until that little rain they had that washed out the rail going to SD.. my wife was down in El Centro when that storm came through.. there was three feet of water in down town El Centro.. plus those drums ... were floating all over, and the tons and tons of fertilizer on the ground and in bags on pallets were lost also.. it was a real mess... lucky she got a second floor room.. and kept her feet dry..

But, being open to their problems and working with them to insure to make sure they could continue to "grow" and still make a "buck" help a lot...

Totally enjoyed this work... the only thing I did not like.. working for the State of California and the Federal EPA.... the politics were just terrible.. as there was money involved... so Agency's were all trying to get in on the "regulation" of this area.. health and environment.. and then throw in Cesar Chavez and it was an interesting groups of people and issues one "bumped" into ...

And you are spot on with the "rivers" ..... it was a problem.. along with the "burying of drums" it was a registered way to dispose .. "bury" we all used to joke that the Alamo River was Mexico's thank for what "we" had done to them over the years on various issue.. is was even way back then.. a really bad situation, as even as bad as "our" growers and industry was... on the other side of the border ... it was at that time .. even worse...

Just recalled that most of the Phosdrin... put up for the western United States was "put up" right by the "track" in Calipatria .... at a facility of Shell's, before they bailed on BK, and sold all their facilities and liability to J. R. Simplot, PureGrow and Western Farm Service...

Would be interested in learning about what your husband found about the area.. it truly was and most likely still is.. a very interesting place.. with a very unique history.. going back many, many years.. and to have been part of the Gulf of California/Sea of Cortez is quite a thought...

Had family (mothers side) that tried to get into farming of Alfalfa in Brawley in the 1920, but lost the farm in the depression..

And I enjoy your pictures from that area... used to stop over by Bombay.. when heading down and jut pull off and turn the engine off .... just to hear "nothing"... really liked that ... have seen some of your shots where you do much the same ... down here in Baja.:):)

White flies love my hybiscus also. They also enjoy attacking my Plumeria and Rose of Sharon leaves.

We still have some 'old stuff' left that wipes them out. My neighbor across the street has a whole row of hybiscus that was seriously infected with them last year. He purchased four bags of lady bugs and that took care of it. He blamed me for chasing my white flies over to his house!

I started to work for the Imperial County Agricultural Commissioner' Office in 1988 when Cal. EPA was being established. Authority for pesticide enfocement was transferred from Calif. Dept of Food and Agricultural to Cal. EPA. Since that time more strict enforcement of pesticide use has been in effect. Pesticide container disposal is one of the areas of concern. It is strictly regulated. Prior to my retirement I was involved in some investgations and enforcement action. Hopefully things have improved since the "good ole' days"

Again, those are just really good photos-----now I hope the next ones will be of that beautiful flower with nice green leaves!

To this day in the Imperial County Garage on State street is an old herbacide Tok drum used for trash. Rohm and Haas discontinued the product back in the mid 70's due to toxicity concerns

We still have a copy of his Thesis book back in the states that we need to dig out. The IID also has a copy---a part of the deal for using their library.

Farmers---having lived in the Imperial Valley and the Central Valley, I would agree that farmers are the salt of the earth people, and often not quick to change. What we have seen cause problems for some is when their own kids go off to college, major in ag studies, and then come back and try to tell dad what all he is doing wrong. That can be fun. :yes::yes:

I have not checked recently, but I wonder if the New River Committee in Calexico is still talking about covering the river like they did in Mexicali---out of sight, out of mind. :biggrin:

And I wonder if ladybugs can be bought down here---we have only seen a couple around and tried to talk them into staying. So far, lucky----no white flies, but we have seen those monsters in town!
