In
the spring of 2002, a week of summer-like weather in early April caused
rapid growth in Michigan's fruit crops and they were several weeks ahead
of their normal development.
On April 22 and
23, a cold air mass from the Arctic moved across Michigan and the rest
of eastern North America and created havoc for fruit growers with colder
than normal temperatures. Widespread frosts resulted in significant
losses to fruit crops in Southwest Michigan and to tart cherries in
Northwest Michigan. The weeks following the frost were generally cool,
wet and windy -- very poor pollination weather. This period of cold
weather ended in mid-May with another series of frosts and freezes from
May 17 to May 21 that severely impacted all the fruit growing regions
of Michigan.
By early June, the
impact of the multiple severe spring frosts and poor pollination was
apparent. Tart cherries and plums suffered 90% damage statewide. Juice
grapes, peaches, pears and apples were severely affected with only 50%
of a crop statewide, and many growers and regions suffering near total
losses. Blueberries and wine grapes suffered less than 50% losses, but
many growers still lost most of their crop.
At a MSU Fruit Area
of Expertise meeting on April 26, it was decided to focus on helping
growers cope with the loss of income in 2002 and their need to maintain
the health of their plants, protecting them from insect and disease
damage and maintain the potential for good 2003 crops. Another focus
would be building awareness in the public and state and federal government
of the scope of the disaster in hopes of gaining an agricultural disaster
declaration and funding to help growers weather the disastrous 2002
crop year.
A concerned effort
was made to get information out to growers quickly. Two special Frost
issues of the Fruit CAT Alert Newsletter were published on April
30 and May 8. |
