Sparganothis Fruitworm Degree-Day Update: as of July 02, 2018

Based on our degree-day (DD) model for Sparganothis fruitworm, first eggs hatched at about 900 DD (see chart). As of July 02, Sparganothis

has accumulated 1,212 DD (using April15 as biofix). This indicates that most eggs should have hatched by now and fruit is susceptible to infestation. Most beds should soon be out of bloom. Thus, if trap counts have been high, then a post-bloom application might be necessary. Growers should consider treatment in the next few days (as soon as bees are removed) to prevent damage to berries. Your best post-bloom options are Diazinon, Altacor, or Delegate.

Fruit IPM for 6/26/18

Peach:

Oriental Fruit Moth (OFM): Second generation adults are flying in southern and northern counties. Degree day spray timing predictions are updated since last week and are shown below. The second brood often causes the most damage on peaches, since larvae can enter both growing tips and young fruit. Particular attention should be paid to non-bearing orchards that may not be receiving regular insecticide applications. OFM can build up in non-bearing blocks and create pressure for production blocks. The timing for second brood OFM applications is NOW in southern counties where mating disruption is not being used. Growers in northern counties should plan of targeting OFM by the middle of next week.

Based on our degree-day (DD) model for Sparganothis fruitworm, peak flight is expected at around 884 DD and first eggs hatched expected at 895 DD (see chart). As of June 21, Sparganothis has accumulated 951 DD (using April 15 as biofix). This indicates that we have passed peak flight and eggs have just started to hatch. I will keep you updated as the season progresses.
