1 See cautions under 1/4-1/2 inch green spray, p. 50.

2 Excellent powdery mildew control is expected when the Rally or Rubigan is used on a 7-10 day interval for scab control. Bayleton should give similar mildew control when applied on a 7-10 day schedule. See also comments about disease management on pages 40 and 62. Do not combine sulfur with oil or apply within 14 days of an oil spray.

Do not combine sulfur with oil or apply within 14 days of an oil spray.

1 Where ERM eggs are abundant, Stethorus punctum adults will continue to move into trees. Begin regular monitoring of Stethorus punctum at this time.

2 Early detection of GFW is important. Tap tree limbs over sheet beginning at prepink. GFW larvae will curl up (grub-like) when dislodged from tree.

3 Adult leafminers may be controlled at tight cluster, or larvae controlled at pre-pink or at petal fall.

4 Pyrethorids (e.g. Ambush, Asana XL, Battalion, Baythroid, Danitol, Decis, Lambda Cy, Mustang Max, PermUP, Pounce, Proaxis, SilencerTombstone, Warrior) are highly toxic to predators. Do not use if Stethorus punctum have appeared in orchard.

5 See note (7) 1/4 - 1.2 inch green spray.

6 See note (8) 1/4 - 1.2 inch green spray.
