As you may have seen in the news clip below, the new study claims that exposure to certain organophosphate pesticides—specifically found on frozen blueberries, fresh strawberries and celery—appears to boost the chances that children will be diagnosed with attention deficit hyperactivity disorder. To read more about what is being reported in the popular press go to the following link: http://today.msnbc.msn.com/id/37156010/ns/health-kids_and_parenting/#ixzz0oDafw65a. The study is published in the journal Pediatrics. The study has been picked up by over 400 national and local media outlets, including the national morning news shows. For those interested, USApple analyzed the study and found: Apples or apple products are not mentioned in the study’s full report or any popular press articles. No data in the study directly links cause and effect, just an association. The study itself says “prospective studies are needed to establish whether this association is causal.” Research methods used were questionable – one-time urine sample and telephone interview. · A single urinalysis which detected OP metabolites was used to determine correlation with long-term disorder (ADHD). · The study’s subjects – children – were determined to have ADHD based on telephone interviews with caregivers, not a doctor’s diagnosis or extensive medical check. The researchers did not consider the children’s overall diet or other possible sources of exposure to OP’s. Information on the use of pesticides in this study does not reflect the significant decline in OP use over the past decade. If exposure to OP pesticides were significant in effecting the diagnosis of ADHD, then there would be a corresponding drop in ADHD diagnosis.

Re: Apple-Crop: Pesticide Rates and Tree Row Volume
Rick: I've been waiting for you to add to the discussion, after our experience with codling moth sprays, etc. Sorry, but no F AND G Notes today. Hope to see you at the Fruit Schools.. Chris -Original Message- From: Richard Weinzierl weinz...@uiuc.edu To: Apple-Crop apple-crop@virtualorchard.net Sent: Tue, Jan 19, 2010 9:45 am Subject: Apple-Crop: Pesticide Rates and Tree Row Volume Hello all. A little context before the main idea about how new insecticides (and other pesticides) are tested in tree fruit crops ... This thread started with a report that Avaunt performed poorly for apple maggot control when used in a spray program that relied on tree-row volume calculations. As a few others have pointed out, this seems to have been a banner year for apple maggot in many areas, so pest pressure likely helped to exaggerate anything less than a very high percentage of control. In addition, the Midwest Fruit Workers (and I think others) rate Avaunt as only Fair for apple maggot control, and several other compounds are rated Excellent or Good. My point ... any weaknesses, even small ones, in the effectiveness of tree-row volume modifications were probably multiplied by pest pressure and a less-than-ideal insecticide for this pest. That said, perhaps something more important in the overall discussion of tree-row volume calculations seems to me to center on the nature of data that support labels and recommendations for newer insecticides. Over the last15 years when I have tested insecticides, the trees that I use are characteristic of modern orchards -- small and well pruned. I determine the amount of water required to give thorough coverage, and that's the spray volume I use (often 100 gallons or less per acre). I determine the portion of an acre represented by the trees in each treatment, and I apply the amount of insecticide on the label (or in the experimental protocol) -- on a per acre basis. I have no illusions that work done in Illinois (not exactly the king of fruit production) determines or dramatically alters national and international labels, but I think most other entomologists test products in a similar fashion -- and pretty much always on small, well pruned trees. One might argue that this means that the per-acre rates on labels for newer insecticides have already been adjusted for (based on) the reduced tree-row volume of small trees. This is entirely different from adjusting the amounts of Guthion or Imidan or other older compounds whose labels may have originated with data from larger trees in older production systems. Those amounts could logically be reduced with the transition to smaller trees over the last few decades, but labels for newer materials such as Avaunt, the neonicotinoids, Delegate, Rimon, Altacor, etc. already reflect the necessary amounts for effective control on today's smaller trees. I realize that there remains a lot of difference in tree sizes in modern production systems, and adjusting spray volume and pesticide rates over those different tree sizes makes sense. Still, as we consider all the expert comments offered on this site over the last several days, it might be wise to also take into account the research basis for the per-acre rates expressed on labels for newer products.

However, I really doubt if anyone has calculated the trade-offs, and it would probably be nearly impossible to do so. We are all so interconnected that it is often very difficult to predict how changes in one arena can totally upset the balances half a world away. (Besides, the world would rapidly run out of food if we abandoned all arid-land agriculture or if we abandoned all pesticides not approved for organic use!)? ? To illustrate the complexities of our interconnectedness: A recent article in Science magazine discussed decisions by an agency in California that decided industries should not receive carbon-related credits for using biofuels because the data collected by this agency indicated that biofuels as currently produced provide no net benefit to the environment. The problem is that the huge amounts of the US corn crop consumed for biofuel production resulted, at least initially, in rising food prices worldwide. That caused farmers in tropical and subtropical climates to remove/burn more forest land so as to convert it to farming. The loss of forest land was calculated to negate the carbon-saving benefits of biofuels. The final comment in that article was from a scientist who noted that we could produce enough crops for both biofuels and human food if everyone became a vegetarian because it takes only 1/10th as much land to support humans on vegetarian diets as on meat-based diets.? ? After reading that comment, I thought it would be interesting to know what would happen if North Americans were told that they could either become vegetarian and continue driving their cars/trucks, or they could give up their vehicles and driver's licenses and continue to eat meat. However, our recent discussion on organic farming has added a new twist: If everyone opted to become vegetarian so that they could continue to drive their cars, we would end up with a world-wide shortage of manure for organic farmers (despite all the BS that comes out of Washington DC!). Given this conundrum, I suppose the ecological choices would be to either become a non-organic vegetarian with a car or an omnivore (organic optional) with no car.? ? Saving the planet gets awfully complicated. And what is the point in eating organic foods to stay healthy (which seems to be the under-lying driver for most organic foodies) if by doing so you end up being the last healthy organism on the planet?? ?

I woke up this morning (about 5 am) thinking of the freeze out in southern Indiana, and the huge pruning job facing my brother, David, at Applacres in 2007-2008. It occurred to me that there are a few things that might make sense with a complete freeze out in 2007 where vigors tree growth will likely be a huge problem in 2008 (close plantings, vigors rootstocks, no crop or very little). In one experiment some years ago, we used 6 reduced rate Apogee (63ppm) +Ethephon (135ppm) + NH3S04 + Choice (a surfactant /penetrant) applications starting at petal fall about 3 week apart . Tree growth (as shoot length of the longest shoots) was reduced to less than 60% of the Controls. Although we did not measure effects on shorting shoots, shoot length and shoot weights were likely much greater. The research paper has been going from editor to editor for over 2 years now and I really do not know the status of it. Publishing is not now on my short list of things to do. The Ethephon reduces the cost of the plant growth regulator combination , and the ethephon has a longer lasting effect on reducing shoot growth than Apogee, but it increases flowering and will cause thinning of fruit above the 135 ppm level with some cultivars. Higher rates of ethephon will have a dramatic effect on shoot growth at increasing rates so if thinning is not an issue (due to the loss of crop) 270 ppm or higher rates might be used in this combination. To further reduce the cost Ethephon might be used alone . The reduced crop trees will flower heavily next year anyway, but Ethephon will further increase flowering so early fruit thinning will be a must in 2008. (Gibberellins can not overcome the increased flowering and will increase shoot growth so that approach will not work, in my opinion in a low crop situation). I have some photographs of the retarding effect of Ethephon + Apogee and will try to post them later.

I see damage to some king bloom of earlier cultivars, but at this point would say there is still the potential for a full crop of apples on our trees. The peaches still have enough live flowers to make a full crop, but I will reserve judgment on them because I think the miserable pollination/ fruit set conditions might be as much of a factor as the freeze in final fruit set in our situation. Yesterday we visited an orchard in central Virginia, south of Charlottesville, which also has the potential for a full crop in spite of cold and windburn on petals of open bloom and flower cluster leaves. Reports from farther south in Virginia are generally less optimistic, with colder temperatures and more advanced bud stage than we had in the Winchester area.
