They Get No Respect:
For at least the past 7-8 weeks, the annual “dog-day” cicadas (Neotibicen canicularis) have been heard singing throughout many NJ locations.They tend to get little respect or media attention & could be called the “weak sister” of the far more publicised periodical cicada species that were present this past spring. The annual cicadas species have less dense populations & their lifecycles are usually 2-3 years compared to the 13-17 years for the periodical cicada species. However, the dog-day cicada emergence is not synchronized, therefore some will emerge every year. Like periodical cicadas, the dog-day males also sing to females to attract a mate. However, the dog-day cicada “electric buzz-saw” screams are not synchronized & even though each individual male is loud, they are not nearly as deafening nor continuous as the noise produced by periodical cicadas. Each male sings for only about 15 seconds & when their numbers in an area are relatively sparse, there is typically many intermittent periods of silence. When populations are more dense, then there may be a continuous non-synchronized buzzing sound that emanates throughout an area.
DEP’s pesticide control program website was updated over the past few weeks to reflect that
“Based on the current COVID 19 public health emergency, the Department has extended an interim policy allowing 100% online CEUs for remaining credits to accommodate for applicators whose 5-year recertification cycle ends October 31, 2021 and 2022. To verify you are eligible, please click HERE.”
However, there are no longer directions explaining where certified applicators can check the status of their credits and the course histories. Growers requesting this indicate it takes some searching to find it. Here are revised instructions to get you there. You might want to bookmark whichever site below gets to the information you need most directly.
To review course history:
Cucurbit downy mildew has been confirmed on pumpkin in Morris County, New Jersey. This is the first report of CDM on pumpkin in the state and region this growing season. CDM was confirmed on cucumber and cantaloupe earlier this summer. Growers should scout all cucurbit crops on a daily basis and initiate a preventative fungicide program. Remember, some CDM isolates fall into Clade II which predominately infect cucumber and cantaloupe, where Clade I isolates predominately infect watermelon, pumpkin, and squash.
For more information on CDM, the clades, and CDM control please click here.
POSTPONED UNTIL 9/21/2021
