Art,


Once the fruit is infested, cold storage for 3 days at 33F will kill the 
majority of larva in the fruit, retaining the integrity of fruit at the time of 
harvest from further injury.

  *   If the fruit are clean (uninfested) at the time of application AND the 
material has a high degree of efficacy in reducing SWD egg laying, the fruit 
will remain clean.

  *   If the fruit has been newly infested with one or more eggs you may get 
some efficacy from the application to reduce larval activity, with protection 
from further infestation  in the field depending on insecticide efficacy. Its 
likely they will remain infested with larval activity increasing in storage 
unless cold treated.

  *   Sound stone fruit are much less likely to be infested. We have only 
reared a singly fly from sound peach. We have seen oviposition on plum with no 
fly emergence. Blueberry have shown to be much less attractive to SWD then 
raspberry and blackberry. A 7 day schedule for blueberry using the best 
materials has been shown to be effective at managing the pest on many farms 
with consistent pest management programming. In the Hudson Valley a 3d program 
is required in raspberry and blackberry for commercial quality fruit.

If you apply a 3 day PHI spray for SWD will it continue to protect the fruit in

Re: [apple-crop] Apples From China?

2014-08-15 Thread Peter J. Jentsch
China is the world’s largest consumer of fruits and vegetables, with a growing 
appetite for high-quality produce. China is also an expanding import market 
(mostly fresh fruits and, to a lesser extent, processed products). The value of 
China’s produce imports increased sevenfold between 1992 and 2001, making it 
one of the world’s fastest growing import markets. (Global Trade Patterns in 
Fruits and Vegetables Economic Research Service/USDA).

Yet China is producing almost half of world total apple production, increasing 
from 33,263,000; 35,985,000 and 37,000,000 metric tonnes from 2010, 2011 and 
2012 respectively while increasing world exports by 10% between 2000 to 2006. 
(Source: World Markets and Trade, US Department of Agriculture, Foreign 
Agricultural Service, May 2007). However, 10%; volume in terms of of world 
export is only 3% of their China's total production!!!

The US has been increasing their shipments of high volume fresh apple to China. 
We will likely continue increase of apple exports until China has ramped up 
their volume and quality of production. Its been my understanding that even the 
Chinese people prefer US apple due to food safety concerns.

Western US apple trade to China and world markets may be well for Eastern 
growers as it will likely reduce the shipments of Washington State apples to 
eastern markets and increase supply for locally grown fruit?

I would favor increased tree fruit trade with China under competitive trade 
conditions based on standardized production practices. As it now stands, the 
regulations do not require the use of production practice guidelines to the 
standards which U.S growers need to abide, creating a competitive disadvantage 
for the US tree fruit producer. Pest management practices, worker protection 
standards and child labor laws shouldnbsp; be instituted within the guidelines 
of production practices, certified by US inspection of farms and facilities, 
just as we have here in the US. Its likely that MRL standards will need to be 
assessed and met, yet there's no mention of MRL's in the regulation. The 
emphasis in the bill on phytosanitation for oriental fruit moth is outdated and 
concerns for newer invasive species should receive a hard review (too late for 
BMSB and SWD invasion over the pst 15 years, having caused millions of $$ in 
production and research loss).


That said, China has not been known for their recent history of protecting 
human rights, product quality or safety standards and should be pressured into 
compliance by world markets to 'come clean'.

[apple-crop] Stone fruit SWD injury

2013-07-14 Thread Peter J. Jentsch
We sampled a range of peach varieties maturing at different dates  throughout 
the season last year. Although we did see one sample with a single adult SWD 
emerge from incubated sound fruit held for two weeks, we didn't see what we 
would consider to be economic injury, again the caveat being, 'of sound fruit'. 
However, damaged fruit from suture splits, bird pecks, insect damage from 
earwigs or Japanese beetle to create openings in the skin are a different 
matter. In these cases SWD will infest fruit as do other Drosophlia sp. A few 
of our growers thought the fly was causing increased brown rot in peaches but 
we didn't find SWD emergence evidence to support the claim. Certainly that 
could be the case in late cherry with reduced fungicide use. We did see late 
cherry varieties in the lower HV with significant egg laying injury this year 
in a site where SWD was captured in low numbers. One monitored site in Dutchess 
County in early July suffered 100% ovipositional injury.  A second site in 
Orange County experienced 70% ovipositional injury during the first week of 
July. However, we have yet to rear out adults from these samples.

This year in the Hudson Valley, as in most monitored sites throughout the 
region, we did capture flies earlier then in 2012, possibly because of the 
addition of yeast/sugar combination floating in apple cider vinegar (ACV) or 
simply because we were looking more intensely. We'll need to again collect 
stone fruit and grape varieties as the season progresses to determine varietial 
susceptibility to SWD. No injury was observed in plums, pear or apple last 
season but by September you could capture them in any fruit growing site in the 
Northeast. Chris Meier even caught flies at the NY, Canada New England Fruit 
Workers meeting in a remote wooded location in Burlington !!

Re: [apple-crop] Stone fruit SWD injury

2013-07-14 Thread Peter J. Jentsch
Dean,

A Penn State Extension Article on SWD Natural History summaries and references 
studies on basic biology of the insect found at  
http://pubs.cas.psu.edu/freepubs/pdfs/xj0046.pdf. Here's a quote from the 
article that discusses aspects of temperature on insect biology.

SWD prefers environments with moderate temperatures and high humidity. Adults 
are most active at temperatures around
70°F, and their activity is greatly decreased when temperatures are only 15 
degrees colder or warmer. Adults need shelter when temperatures drop below 
about 50°F and begin hibernation at 40°F. Female adults exposed to cold 
temperatures lay very few eggs, and the eggs and larvae are killed by several 
days of exposure to temperatures just above freezing. Thus, seasonal 
populations are likely to start out extremely low in each spring, increase as 
temperatures warm, decline during hot spells, and then increase very rapidly 
during early fall when temperatures become more ideal. Regardless of whether 
SWD can overwinter in a region, it can be readily reintroduced in fruit that is 
shipped from warmer regions.

The stripping of trees of fruit by squirrels this season has been dramatic.

The losses early in the spring from freeze of food sources may have some

Hello.

I had a report from a NY grower near Whitehall NY, virtually astride

causing significant fruit loss due to feeding.  He reports never

I then had a call from an AP reporter asking about this and other
situations in VT.

Trapping is out of the question, as are rodenticides as fruit is on
the trees presently, customers are in the orchard, and non-target
species would be greatly at risk. For much the same reason, shot guns
and/or squirrel guns have very limited utility.

I am speculating that normal food stocks  of these critters has been
negatively effected by drought conditions in June, July, and early
August, and perhaps also, that several mild winters and earlier
springs has allowed greater survival and reproductive numbers.

(I understand that black bears are also seeking alternate food
sources as customary wild foods were severely impaired due to weather
conditions.)

While such population surges likely cyclically normal, this grower
reports never having seen such squirrel numbers - and damage; warming
climatic conditions are likely amplifying the cyclical potential .

Perhaps others can offer effective control methods and a more
accurate assessment of what may be going on.

Re: [apple-crop] definitions question: first, second, third cover

2011-04-11 Thread Peter J. Jentsch

Greetings Rye,

I believe this term is a carry over from a time when pest management 
applications would 'cover' the commodity in a blanket of spray 
following the critical petal fall application. This PF event 
typically occurs at roughly 80% of the petals falling from a variety 
such as Mcintosh in apple. At this point in time the flowers loose 
their attractiveness to bees allowing for insecticide pest management 
to occur.


In New York's Hudson Valley, this application of insecticide will 
control European apple sawfly, plum curculio, the overwintering stage 
of obliquebanded leafroller, tarnish plant bug, rosy apple aphid, and 
others, depending on the insecticide used.


Typically insecticide applications follow a 10 to 14 day interval 
called cover sprays or covers for short, depending of course on 
insecticide longevity and the weather (OP's longer, Bt's shorter). 
The residual of the previous application carrying over for this 
interval based on its residual to withstand weathering or hydrolysis, 
its U.V. stability and so on.


These applications then target the same insect (PC for the 1st and 
possibly 2nd cover), or a different insect species or complex of 
insects (such as codling moth at 2nd, SJS at 3rd cover; summer 
generation of OBLR at 4th cover; apple maggot  SJS at 5th -7th 
cover) at different periods relative to their timing after petal 
fall. All of which depends on pest management strategies, weather, 
population density to name but a few of the variables that increase 
or decreasing the timing interval.


Regards,

Peter


Hello all,

I'm looking over pesticide information and I see a lot of references

first cover spray, second cover spray and third cover spray.  All 
references seem to expect the reader to know what that is.

4-6 weeks after petal fall.  Another reference seemed to refer to 
the number of wet days to get to second cover and that didn't make 
any sense to me at all.


I guess I'm really unclear on what cover means in this context. 
What does the term refer to?  What is being covered at these stages 
and/or what is doing the covering?  Or what observation do you make 
and say ah!  we are reached second cover today!  (same question 
for first and third.)


Also, what is the relationship between second cover and second 
cover spray? (same question for first and third)  I think I would 
understand once I understand what second cover is, but my general 
confusion on the topic leaves me with little confidence in that.


I have found references for definitions of some stages such as green 
tip, pre-pink, pink.  But these cover stages elude me.


Thanks for sharing your expertise!

Apple-Crop: Apple growers thank Congressional leaders

Apple growers thank Congressional leaders
Posted by Debra J. Groom/The Post-Standard May 20, 2009 2:37PM
This news just in from the New York Apple Association in Fishers, NY

The New York Apple Association Wednesday thanked members of the 
state's Congressional delegation for support of Agricultural Job 
Opportunity, Benefits and Security Act of 2009 (AgJOBS).

The bill was introduced in Congress last week.

The bill proposes to create a program to allow migrant laborers to 
continue to work on farms. The legislation also restructures and 
reforms the current H-2A temporary agricultural worker program by 
substantially streamlining the program's administrative procedures.


Despite the high unemployment rate, our industry still does not have 
a reliable workforce and will not until the AgJOBS bill is passed, 
said Jim Allen, president of the New York Apple Association.


Sen. Charles Schumer, a longtime supporter of New York agriculture, 
signed onto the Senate version of the bill (S.1038) which was 
introduced by Sen. Dianne Feinstein (D-Calif.).


In the House, Reps. Louise Slaughter (D-28), Christopher Lee (R-26), 
Eric Massa (D-29), John McHugh (R-23), Dan Maffei (D-25) and Michael 
Arcuri (D-24) all signed on in support of the House version 
(H.R.2414), which was introduced by Reps. Howard L. Berman (D-Calif) 
and Adam Putnam (R-FLA).


Over the past three years, immigration raids throughout western New 
York left apple growers scrambling to harvest crops.


Apple growers wholly depend on a migrant labor force coming to the 
state to pick apples in the fall. Every apple --- usually more than 3 
billion per season --- is picked by hand by skilled migrant laborers.


There is no viable source of local labor to draw from since few 
people have an interest in crop-picking work on a farm, even in a 
recession economy, Allen said.


The AgJOBS legislation will ensure labor-intensive agriculture has 
access to a stable, legal and predictable supply of skilled labor.


The bill also proposes to eliminate the cumbersome labor 
certification process, streamline the process for admission of H-2A 
aliens and allows aliens not currently eligible to participate in the 
H-2A program to acquire H-2A status.


New York ranks second in apple production nationwide with nearly 700 
orchards and more than 25 million bushels harvested last fall.

Re: Apple-Crop: Pollinating bees

2007-03-29 Thread Peter J. Jentsch
The CCD (Colony Collapse Disorder ) working group recently published 
a report of their finding entitled 'Fall Dwindle Disease: A 
preliminary report December 15, 2006'. It can be found at:


http://maarec.cas.psu.edu/pressReleases/FallDwindleUpdate0107.pdf

Although the group is looking into the sub-lethal effects of 
insecticide and insecticide / fungicide interactions through 
pesticide residue analysis, they have found at least some indication 
that viral and or fungal presence may be at least in part associated 
with the collapse.


Peter

Has there been any comment among apple growers in the US on the 
continuing sharp decline in bee numbers?
I read the following recently, and believe that a few parts of 
Europe are beginning to see localised colony collapses also.


Since last November, the US has seen a decline in bee populations so 
dramatic that it eclipses all previous incidences of mass mortality. 
Beekeepers on the east coast of the United States complain that they 
have lost more than 70 percent of their stock since late last year, 
while the west coast has seen a decline of up to 60 percent. In an 
article in its business section in late February, the New York Times 
calculated the damage US agriculture would suffer if bees died out. 
Experts at Cornell University in upstate New York have estimated the 
value bees generate -- by pollinating fruit and vegetable plants, 
almond trees and animal feed like clover -- at more than $14 billion.


Scientists call the mysterious phenomenon Colony Collapse Disorder 
(CCD), and it is fast turning into a national catastrophe of sorts. 
A number of universities and government agencies have formed a CCD 
Working Group to search for the causes of the calamity, but have so 
far come up empty-handed. But, like Dennis vanEngelsdorp, an 
apiarist with the Pennsylvania Department of Agriculture, they are 
already referring to the problem as a potential AIDS for the bee 
industry.


One thing is certain: Millions of bees have simply vanished. In most 
cases, all that's left in the hives are the doomed offspring. But 
dead bees are nowhere to be found -- neither in nor anywhere close 
to the hives. Diana Cox-Foster, a member of the CCD Working Group, 
told The Independent that researchers were extremely alarmed, 
adding that the crisis has the potential to devastate the US 
beekeeping industry. It is particularly worrisome, she said, that 
the bees' death is accompanied by a set of symptoms which does not 
seem to match anything in the literature.


In many cases, scientists have found evidence of almost all known 
bee viruses in the few surviving bees found in the hives after most 
have disappeared. Some had five or six infections at the same time 
and were infested with fungi -- a sign, experts say, that the 
insects' immune system may have collapsed. The scientists are also 
surprised that bees and other insects usually leave the abandoned 
hives untouched.


Nearby bee populations or parasites would normally raid the honey 
and pollen stores of colonies that have died for other reasons, such 
as excessive winter cold. This suggests that there is something 
toxic in the colony itself which is repelling them, says Cox-Foster.
