(set up traps at silver tip)

Tree stage for McIntosh (Greenville area)
4/5/04 – Silver tip
4/13/04 – Green tip
4/18/04 – Half inch green
4/26/04 – Tight cluster
5/1/04 – Pink
5/2/04 – King bloom
5/5/04 – Full bloom
5/12/04 – Petal fall

5/12/04 – Saw many leafminers on leaves, laying eggs. Even in blocks with relatively low levels of leafminer adults could face more leafminers than anticipated. There has been PLENTY of good weather for egg laying. I expect to see many mines!
Saw eggs hatched as well.
