Fruit IPM For 6/4/19

Peach:

Plum Curculio (PC): PC oviposition should be done in all areas of the state, and there is up to 2-3% of fruit injury with egg scars. We have accumulated about 911 DD since petal fall (apple) in southern counties and just over 663 DD in Hunterdon County. The Cornell model calls for insecticides applied up to the 340 DD₅₀ mark. Therefore, all sprays for this insect should be done. The model assumes a single generation in NJ, which is historically what we have had. New research from Anne Nielsen’s lab is telling us that the southern strain of PC is also present in the state. This is a multi-voltine strain, which means there is more than one generation per year in some parts of the state. Therefore with an early spring, we may see additional injury later in the season.

Grape IPM School March 31, 2015

With all the snow and cold weather it’s hard to believe that it’s March already and Spring is right around the corner! It’s time to start planning your pest management programs.

For the first time, we are hosting an all-day “Grape IPM School”. The aim of this “school” is to introduce and update wine grape growers of all experience levels to the key pest issues they face. We will discuss the basics of Integrated Pest Management (IPM) and how to apply it to your vineyard. We have invited regional experts who will share their expertise on how to use IPM to scout for and manage grape berry moth, grape root borer, plant viruses and diseases, among others.

Please join us at the Rutgers Agricultural Research and Extension Center (RAREC), 121 Northville Rd., Bridgeton on MARCH 31st. Mark your calendars, more details to follow….

Does a Harsh Winter = No Crop Pests?

It has been in the news, of course, about the severity of the 2013/2014 winter with record breaking low temperatures and higher than normal snow amounts in many locations. So how does all this translate to crop insect pests? As an article that I read last week said, “It’s complicated”.

There are many factors that affect insect mortality through the winter months. It is not only just the cold, but the amount of snow cover, overall fitness of the insects going into the winter diapause (hibernation), how well protected were they from the cold, what the weather conditions are coming out of winter, and so on.
