Cucurbit downy mildew has been reported on cucumber in southern New Jersey (Salem County). This is the first report of CDM this growing season in the state. All cucumber growers are encouraged to scout fields on a daily basis and begin preventative fungicide programs if already not initiated.

IPM Update 7/03/19
Sweet Corn
A few European corn borer (ECB) moths were captured this past week, but numbers are very low, and no map will appear in this edition. It is unclear at this stage if these individuals represent the onset of a second flight. Catches over the upcoming week will clarify the situation with this pest. No new feeding should occur until the second flight arrives.
Growers should continue to scout whorl and pre-tassel stage plantings weekly and consider treating when infested plants exceed 12% in a 50 plant sample. As plantings proceed to the pre-tassel stage, ECB larvae may be found in emerging tassels. It is a good idea to treat individual plantings as they move into the full tassel/first silk stage one time. This eliminates any ECB larvae that have emerged with the tassels as they begin to move down the stalk to re-enter near developing ears.
Useful insecticides for this particular application include synthetic pyrethroids (IRAC Grp 3), spinosyns (including OMRI approved Entrust) IRAC Grp 5), and diamides such as Coragen (IRAC Grp 28) or materials such as Besiege which include the active ingredient in Coragen. Synthetic pyrethroids alone should NOT be used for corn earworm (CEW) protection on silking corn. Control with these materials is very inconsistent.
The highest nightly trap catches of ECB for the week ending 7/03/19 are as follows:
| Denville 1 |
| Flanders 1 |
| Milltown 1 |
| Monroeville 1 |
Fruit IPM For 07/03/19
Peach:
Oriental Fruit Moth: Second generation timings are updated below. Second flight adults are still flying statewide. Treatments for the second generation have just finished in statewide. Applications for OFM should now be made only if trap captures exceed and average of 6 moths/trap. [Read more…]

Post-bloom Insect Pest Control Recommendations
As we approach the end of bloom, growers should consider the need for any post-bloom applications. The main pest targets for these applications are mainly Sparganothis fruitworm and spotted fireworm.
Sparganothis fruitworm (SPARG) – If your farm has high pheromone trap counts, you should consider managing this pest as soon as bees are removed. The timing for this 1st post-pollination spray is at 2 weeks after peak pheromone trap catches, which usually coincides with this time of the year.
Spotted fireworm (SFW) – SFW is one of the most important pests in New Jersey. Male SFW moth catches typically peak in the second through third week in June. Although trap catches give an indication of population size, these numbers not always correlate with numbers of egg masses. This insect becomes a problem in “weedy” beds because female moths lay their eggs predominantly on weeds. Thus, growers need to monitor for the presence of SFW egg masses on weeds (broadleaf species and grasses). Keeping beds clean from weeds will keep this insect under control. Egg masses should be hatching by now. SFW larvae from this generation feed on foliage as well as fruit.
Control Options – Insect Growth Regulators (IGRs) (e.g. Intrepid and Confirm) are effective against SPARG. Alternatively, if you have used IGRs intensively (e.g. last year and this year as a pre-bloom or bloom spray), and would like to rotate with other chemistries, you may want to use Altacor, Delegate, Exirel, or the broad-spectrum insecticides Diazinon or Lorsban. Broad-spectrum insecticides are also a choice if you have high blunt-nosed leafhopper populations because Intrepid, Delegate, and Altacor will have no effect against this insect. If you are an Ocean Spray (OS) grower please check restrictions on the use of these insecticides. Lorsban in particular can’t be used by OS growers after bloom due to MRLs for exporting cranberries. If you are an OS grower and want to use a post-bloom application to control SPARG then Delegate, Altacor, or Diazinon (no aerial application allowed) would be your options.
Blunt-nosed leafhoppers – The best timing for controlling blunt-nosed leafhoppers is before bloom when they are immatures. At this time
Table 1. Leafhopper control options
of the year, most of the population are adults and already laying eggs. If you did not spray before bloom and have a high leafhopper population, you may consider a post-bloom application to prevent from an increase in population size. You may also consider spraying next year to control for those immatures that will emerge from the already laid eggs. See Table for control options. Please check, especially for Ocean Spray growers, the restrictions based on maximum residue limits (MRLs).
