We are located on the Illinois/Wisconsin state line just south of Lake Geneva, WI and have missed all of the hail. I use Weather Underground to track storms and almost all of the storms have either tracked south or north of us. Weather Underground provides storm cell information that includes the potential for hail within the storm cell. We have had several tornadoes with heavy hail over the past 2 weeks, but all have missed us. We keep kidding around and saying that God has put a bubble over the orchard to protect us from hail damage. Last week there was hail to the north, south, east and west of us with a tornado to the northeast and southeast of us and yet nothing but rain here.

But all of this rain has created the worst apple scab we have seen in years. We even have scab on some of our resistant varieties like Red Free and Jonafree. I use Specware's Disease Models and we have sprayed regularly with Dithane, Nova, Captan, Flint and Pristine and still have some scab throughout the orchard. We have had over 200 wet hours since April 1 and due to the rain were unable to get our copper spray finished on 3/4 of the orchard. By the time it dried out enough to get through the orchard, the trees were already past 1/4" green. We made sure we got our fungicides on in a timely manner and mixed either Dithane or Captan with our SI or Strobilurin sprays. So, we have either had heavy washoff from rain or our scab is now fungicide resistant. I have samples at Purdue for resistance testing and am also getting our resistant apple varieties tested. So far there has only been very minor scab damage to apples, not enough to cause economic impact. I used Pristine in our last spray as an antisporulant to head off the active lesions, and we have finally gotten four days in a row without rain and temps in the high 70s and low 80's so I think the worst is finally over, but it has been a challenge. Any one else had the same issue with scab?

Subject: Re: Apple-Crop: Hail in the Great Lakes area


I heard a report today on an Albany, NY radio station that up to 1/3 of the NY apple crop may have been impacted (particularly western New York) and that they are actively seeking federal disaster assistance? (But that is the media, although it was public radio, :-)) I know at least two significant orchards in the upper Connecticut River valley of Massachusetts saw some hail damage from the same set of storms that crossed NY earlier this week, and one orchard in eastern Mass. had hail the day after. Could be along summer if the weather pattern holds...

Greetings,

Just saw a report on hail in the Great Lakes Area. Could any of our friends update us as to how bad it was ?

Hopefully the orchards were spared....
