Codling moth.
Control is necessary in orchards
where the pheromone trap capture exceeds 5 moths/trap/week.
Protracted first generation flight in recent years may require
management through third cover. a. Spray timing for
optimal codling moth control, based on DD accumulations from
biofix (base 50°F), will differ
according to the material used. Insect Growth Regulators (IGR)
(e.g. Intrepid, Esteem, Rimon) and neonicotinoids (Assail,
Belay) should be applied just before egg-hatch starts, whereas
other recommended materials should be applied soon after
egg-hatch has begun. Sprays for first brood control should be initiated as
follows: Rimon at 50-150 DD,
then after about 2 weeks, with the exception of Minecto Pro,
if needed, at 400 DD.
Assail, Belay, Esteem, or Intrepid at 150 DD, then after about 2
weeks, if needed, at 450 DD.
For all others apply at 250
DD, then again at 550
DD, if needed. For second brood, initiate
control with Rimon at 1050-1150
DD, then after about 2 weeks if needed, at 1450 DD. Assail,
Belay, Esteem or Intrepid at 1150,
then at 1450-1500 DD,
if needed. For all others, apply at 1250 DD after spring
biofix, then at 1550-1600 DD,
if needed. For third brood
control, control should be initiated if the pheromone trap
capture threshold (see above) is exceeded.
Tufted apple
budmoth. Intrepid, Proclaim, Altacor, Delegate,
Exirel, Voliam Flexi, or Besiege will provide the best control
in most situations.For first brood control, these
products should be applied as a complete spray at 585-640
DD from biofix (base 45ºF, Table 22), or as two
alternate-row-middle applications 7 days apart beginning at 530
DD.An additional application may be needed (in 14 days
for complete, in 7 and 14 days for alternate-row-middle) in
high pressure situations. For all other materials, control
first brood with two complete applications at 530-585 DD
and 805-855 DD. Alternate-row-middle
applications should commence 50-75 DD earlier and be repeated
every 7 days for a total of up to four applications, depending
upon insect pressure.For second brood control, apply
Intrepid, Proclaim, Altacor,
Delegate, Voliam flexi, or Besiege
as two complete
sprays at 2355-2435 DD and 2665-2740 DD, or as four
alternate-row-middle applications, 7 days apart, beginning at
2280 DD after spring brood biofix. For all other
materials, control second brood with two complete applications
at 2280-2355 DD and 2665-2740 DD, or four alternate-row-middle
applications at 7-day intervals, beginning 50-75 DD earlier.
Oriental
fruit moth.
Peach - First brood: Intrepid or Assail at 70-100
DD, then at 250-275 DD, if needed.
Organophosphates, carbamates, pyrethroids, Altacor, Delegate, Voliam Flexi, or Besiege
at 170-195 DD, then at 350-375 DD, if needed.
Second brood:
Intrepid or Assail at 1050-1100 DD, then at 1350-1400
DD, if needed. Organophosphates, carbamates,
pyrethroids, Delegate, Voliam Flexi, or Besiege
at 1150-1200 DD, then at 1450-1500, if needed. Third brood: Organophosphates,
carbamates, pyrethroids, Altacor, Delegate, Voliam Flexi,
or Besiege
at 2100-2200 DD,
then at 2450-2500 DD, if needed.
Apple - First brood: Rimon at 200-250 DD.
Intrepid, Belay, and Assail at 250-275 DD.
Organophosphates, carbamates, pyrethoids, Delegate, Avaunt, or Voliam flexi at 350-375 DD. Second brood: Rimon at 1300-1350 DD. Intrepid, Belay,
or Assail at 1350-1400 DD.
Organophosphates, carbamates, pyrethoids, Delegate, Altacor,
Avaunt, or Voliam flexi at 1450-1500 DD. Third brood: Rimon at 2300-2350 DD. Intrepid, and Assail at 2350-2400
DD, then at 2800-2900 DD, if needed.
Organophosphates, carbamates, pyrethoids, Delegate, Altacor or Avaunt, Belt, Voliam Flexi
or Besiege
at 2450-2500 DD,
then at 2900-3000 DD, if needed. Control of the fourth
and fifth broods should be maintained in orchards where the
pheromone trap threshold is exceeded.
