Early Bloom Brings High Risk Of Freeze Losses
A leading Cornell University researcher says early bloom can bring a huge risk of spring frost-induced crop loss, which means growers should be prepared.
Mild weather weather conditions can have a significant effect on tree fruit, according to Cornell University researcher Terence Robinson.
In the latest issue of Cornell’s “Scaffolds” Newsletter, Robinson says the physiology of trees during dormancy is a highly complex phenomenon. The tree’s internal growth inhibitors affect dormancy timing, and early warm temperatures followed by a cold spell can dramatically affect this timing.

Thank you for this information. It is really needed this year in these rising temperatures across the eastern half of the nation. One question - a dormant oil spray was applied this past Sunday 3/18/12 on my apple trees. When can I put the first fungicide on? If it is to be when 1/2" green is showing, it's probably tomorrow, but that's not giving the 10 day span of time needed between the above two applications. Please advise. Thanks.
