Degree Day (DD) Accumulation Application Notes
610 Products with adulticidal/contact activity (kills adult moths) can be applied after average first moth emergence but before first egg hatch (610-955 DD) if population is above threshold as indicated by trap captures.
815 Products with ovicidal activity (kills eggs) can be applied between first egg laid and first egg hatch (815-955 DD)
955 Products with larvicidal activity only (kills larvae/worms) should be applied just prior to first egg hatch (955 DD)
1188 Peak moth emergence should be reflected in peak trap captures.
1393 Consider reapplying ovicidal/larvicidal products if recommended by label (may be necessary for soft or highly selective materials)
1533 Some larvae will already be in nuts and cannot be managed by this time.
