News & Announcements

Seeking Entries for the 2019 Sweet & Hard Cider Contests

Cider making is starting, so make sure to pull some samples to submit for the 2019 Sweet and Hard Cider Contests! The 30th annual Sweet Apple Cider Contest and 17th annual Hard Cider Contest will take place on Thursday, January 9 in conjunction with the Illinois Specialty Crops, Agritourism, and Organic Conference. For the Apple Cider Contest, contestants are asked to submit a one-gallon full container of unclarified apple cider that may be fresh or have been stored frozen. Hard apple cider contestants are asked to submit a one-quart, but no more than a one-gallon, container of product for the hard apple cider-judging contest.

Regional Reports

From southern Illinois… November has continues the trend for colder than normal temperatures. We have had a few mornings down to 18-20˚. Highs have varied but not much higher than 40s and 50s and a few days only got into the 30s. Last Wednesday night into Thursday we had our first snow of the year. Most of southern Illinois received from 2-6”inches of snow. It did not hang around long as we had temperatures in the 40s and 50s in the days after that. Beyond that we have been wet with the week prior getting 2-3 inches of rain across a few days. Looking ahead I think the weather is supposed to be nicer for the upcoming thanksgiving week.

Field work has slowed quite a bit with the cold and wet. Just in the last week we planted what will be probably the last of some cover crops. We both broadcast and no-till drilled cereal rye. Especially for the broadcast rye the snow was probably just right to get it some moist conditions. Now if we get some warm weather this upcoming week it should sprout and get established. Often later planted cereal rye will not look like much at all until spring. Even if you don’t see much above the ground there are often many roots growing holding and protecting the soil through the winter.

Despite the cold our cool-season, high tunnel crops are still doing well. Below are some high tunnel observations for the high tunnel at the Jackson County Extension Office by Program Coordinator, Maggie Ray:

In the high tunnel, we will be pulling the last of our peppers out. They did not survive the lows of Friday, November 9th which were in the low 20s. The row covers were brought out Friday afternoon to cover our smaller fall plantings and winter greens. The arugula, lettuce, spinach, carrots, and broccoli are doing great! There is still parsley in the bed from this summer and it is thriving as well. The early planted carrots (Oct.8th) all have at least one or two true leaves and I have had to go through and thin them. The late planted carrots (Oct.29th) are just starting to come up, very slowly now.

The arugula was growing very steadily and I would have harvested in a week but now I think it might be a little longer with night time temps being so cold and the cloudy weather.

This week (11/11-11/17) because of the cold daily temperatures, mid-thirties, the tunnel will not need to be opened, but the beds do need to be uncovered to soak up any sun that shows itself. Friday and Saturday are calling for the upper 30’s and low 40’s, if the sun is out the tunnel may need to be cracked. It shouldn’t get more than 70 degrees in there but with these low night temps we want to lessen the shock of the cold. Going from 70 to 20 isn’t that pleasant! Although this morning at 8:45 it was about 27 degrees (F) outside and 41 degrees (F) inside!

Be watching the calendar for all of the dates for those upcoming winter meetings, some even starting in December. Take advantage of all of the expertise we have at these programs to help you with your production. In the meanwhile, hopefully, we will still get some tastes of fall weather before we go any further into winter weather!

From Dixon Springs Ag Center…In preparation for the below freezing temperatures that hit our region a couple of weeks ago, all of the injectors and water hoses were removed from the high tunnels. Without supplemental heat, we didn’t want to run the risk of cracking or busting our irrigation components. The few remaining tomato and pepper plants still growing in the hydroponic tunnel were taken out by the cold temperatures. The strawberries in the vertical stacks held up fine to the cold temperatures, but with no water, they have quickly wilted down. We have started planning for the 2019 season, discussing what crops and treatments will be demonstrated, as well as thinking about planting schedules to accommodate the space that will be needed for the Specialty Block Grant funded project focusing on winter production in 2019-2020. Look for a survey in the next issue of the newsletter that will be asking growers what varieties of carrot, kale, lettuce, and spinach have worked well for them during winter production.

Fruit & Vegetable Production & Pest Management

Balancing Pest and Pollinator Management

A recent article in the Purdue University’s “Vegetable Crops Hotline” highlighted research comparing the use of economic thresholds (IPM) versus preventive pesticide applications (conventional) in melon production. The research showed that the plots using thresholds had higher yields, but more insect pests.

The IPM system had no insecticides applied to watermelons at planting, and foliar sprays were only applied when striped cucumber beetle, reached the economic threshold of five beetles per plant. The conventional plots were given a neonicotinoid soil drench at transplant, and 4-5 pyrethroid sprays were applied throughout the summer regardless of pest pressure.

How can this be, higher melon yields and higher pest numbers? The research group believes the reason is the non-target effect of insecticides on visiting pollinators. “During 5 weekly (scouting) surveys during peak watermelon flowering, there were 653 pollinators in the IPM plots, as opposed to just 349 in the conventionally managed plots.”

Also, they recorded the number of flower visits and pollinating events were recorded for all pollinators. The plots using economic thresholds (IPM) to determine need for pesticide applications had twice as many total flower visits and three times the pollinating events as the conventional plots. “Since multiple insect visits are required for watermelon to produce healthy and marketable fruit, the reduced frequency of pollination could be leading to the differences in yield. These trends show that a “less is more” approach may be a superior management strategy when it comes to insecticides in watermelons and the other vegetable crops that rely on bees for pollination.”

This is an ongoing project at Purdue University being led by Jacob Pecenka, an entomology PhD student.
