I have read the publication for citrus greening action in Louisiana. I read that the citrus to be moved must be drenched a minimum of 30 days before movement. It also must undergo a foilular spray every two weeks prior to movement. They list the cemical with the active ingredient to use for the drench and the spray. They do not tell you that one can not find these chemicals anywhere. Same with the fire ant program...they require that you treat plants that are moved in dirt with Dursban...but dursban has been off the market for some time here. What is one to do......

Can anyone put me in touch with or direct me to a website with current information as to what Louisiana and the USDA expect us to do to abide by the rules governing the movement of citrus in order to control ACP and greening?????I have studied the information and made some calls but I am no closer to being able to drench and spray within their parameters than I was two months ago......HELP...............................David

Dursban, once a very excellent and commonly used insecticide for home, industry and agricultural, an insecticide that did an outstanding job, was taken out of use by (you guessed it) EPA = (Eliminating Productivity in America)

I am probably one of those people responsible for the removal of Dursban from the market. I published a paper on a human poision cases involving Dursban and found that it was probably 10 times more toxic to humans than to rats since humans metabolize it to a form that is probably more toxic while rats do not.

I also know of a case where it was used inside a home around floors and baseboards and probably resulted in the death of a toddler.

There are newer pesticides on the market like synthetic pyrethroids that are very effective on insects but much less toxic to humans and mammals.

But can they kill earwigs?!?! Very Happy I've got so many pesticides surrounding my house that I think I'm starting to see a glow. One of which is made from pyretrin, but I don't believe is synthetic.

On a side note, does anyone know how is pyretrin extracted from the Pyrethrum plant? I planted some from seed, but don't know if the plant itself will repel pests without being extracted.

An insecticide is found to be actually poisonous, can you imagine that? Synthetic pyrethroids are OK with EPA, only because in relation with what actually works, and actually does an excellent job, synthetic pyrethroids are a very poor substitute. Natural pyrethrums require 4- 7 sprays to obtain good field control, even the better (stronger) synthetic pyrethroids still require 2 or 3 sprays to obtain control. Pyrethrums might be good enough for an aphid on a garden rose, but worthless in commercial agriculture. EPA believes in the ridiculous phrase --- "If it saves only one life, wouldn't it be worth it" ---NO---NO---- NO--- By reducing the USA speed limit to 10 miles per hour, if it would save only one life, wouldn't it be worth it ?????????? If EPA out lawed everything that killed a toddler, we would be farming with fly swatters. Is EPA coming to nannyism?

Look at the poor ladder, there is not a spot left any where on a ladder to place yet one more safety sticker.

Not to mention how many people have died from malaria since they banned DDT.

Philip I read somewhere the number of people believed to have died, and continue to die to this day, from malaria after DDt was banned, but now I cannot remember, but it is a HUGE HUGE number. But Philip, if banning DDT will save only one bird egg, wouldn't it be Worth it? - Millet (1,364-)

I remember reading that DDT is still used in some places for specific reasons. If I remember correctly it is used in the walls of dwellings. That way it was contained and not released into the environment as readily.

But I may be wrong

In Africa, the American firms still sale DDT and HCH. It is forbidden in Europe and America but who cares for these black savages?

If you hate America so much, why do you post on American based sites? I am sure the chinese are making much worse toxins in africa.

Because of a lack of time, I haven't read this entire thread carefully, but I am not sure the original question remains unanswered. Here is a link the USDA regulation that now applies:

http://www.aphis.usda.gov/plant_health/plant_pest_info/citrus_greening/downloads/pdf_files/DA-2009-06.pdf

Here are some the pertinent sections:

Treatment:

"i. Regulated articles not intended for consumption must be treated with a drench containing imidacloprid as the active ingredient within 30 days prior to shipping and also be treated with a foliar spray with a product containing either acetamiprid, chlorpyrifos, or fenpropathrin as the active ingredient within 10 days prior to movement."

Required labeling:

"Limited permit: USDA-APHIS-PPQ. Not for distribution in AZ, American Samoa, Northern Mariana Islands and the Virgin Islands of the United States or those portions of CA and SC not quarantined due to the presence of ACP"

Plants being shipped must be inspected by persons authorized by the state, and accompanied by the necessary paperwork. This info should be available through your state Department of Plant Industry (or equivalent).

I believe chlorpyrifos (active ingredient in Dursban) is available in South Carolina (and Louisiana) but restricted to certified applicators. As you can see, there are other contact insecticides listed.

Hope this helps. It is, of course, all subject to change.

From my understanding about the with draw of chlorpyrifos (Dursban), which was a Dow product, the EPA made Dow stop manufacturing the product, but allowed Dow, and Dow's distributors, to continue the selling of Dursban until all of the current inventory was depleted, then that would be the end. As far as obtaining a certified applicators license, the procedure is very simple, and very easy. In Colorado, and I presume it is the same all over the USA, we attend a 1/2 day seminar, in which the test booklet is passed out to each attendee. The test is open book, and the instructor starts with question #1 gives approximately a 4 or 5 minute discussion on the the first question, in which he actually gives the answer, and all of the attendees fill in the answer. Then the instructor goes to question #2, and gives another short talk and answers # 2, and so on, through the entire test. Therefore, 100 percent of the attendees always pass. In my region, the test is given once a year, where new people obtain their license , and also people who need to renew their old licenses. With the license, one can purchase just about anything available that one needs, including insecticides, herbicides and etc. I believe anyone can obtain an applicators license to purchase restricted chemicals, whether they are in a related business, or just a home owner. There is really noting much to it. - Millet (1,364-)

I think most people care a little more about their toddlers than you do. Based on the human poision case I published, it appears Dursban is about as toxic to humans as parathion--the chemical the Germans developed for killing people--it just happened to work on insects as well.

Personally, I think spraying a field 3 times is a minor inconvenience compared to the loss of human life.

In my limited experience analyzing human remains for pesticide residues, I saw about a dozen deaths caused by organophosphate pesticides, including a 9 yr old and a 16 yr old. I'm sure there were many more as I only saw cases from one state for about 5 years. I guess to you they were just the dumb ones that didn't deserve to have their environment protected.
