Blightline September 8

Blightline September 8

No new late blight has been reported in ND, MN or MB the past week. The only confirmed late blight this season was in central MN in processing potatoes, and that was late in the season; fungicides applied and fields killed to reduce late blight spread and severity. We have seen a few samples with bacterial soft rot due to some scattered late August rains, and some common scab. Otherwise, our crop looks very good and is of high quality.

Aphid Alert for week ending Sep. 5

Aphid Alert for week ending Sep. 5

A marked drop in vector numbers with fewer traps reporting as the season closes down. Nate reports that there are still a lot of soybean aphid (87), bird cherry oat (29), and corn leaf (28). Green peach aphids were also captured this week at Forest River, Gully, and Hallock.

Managing Fungicide Resistance in Potato

Managing Fungicide Resistance in Potato

This presentation will help potato growers, consultants, agribusiness personnel and others associated with the potato industry in North America understand and manage problems associated with fungicide resistance. This presentation will discuss the different modes of action of fungicides currently registered for use on potatoes in the USA, the risks of developing fungicide resistance and practices to minimize the development of fungicide resistance problems in production fields.

Fuel Your Empty Tank With Breakfast

Fuel Your Empty Tank With Breakfast

Do you ever skip breakfast? People have lots of reasons. Maybe they hit the "snooze" button once too many times on their alarm clocks and they didn't have time to grab something. Maybe someone ate the last of the cereal and left the empty box in the cupboard. Maybe they just weren't feeling hungry. Others might be trying to cut some calories out of their diet to lose weight. Some might think that breakfast is only important for kids.

Deciphering "Sell By" Dates

Deciphering "Sell By" Dates

I'm very confused by the dates on food packages at the grocery store. I was reading the "sell by" dates on an egg carton, milk carton, and yogurt container in my refrigerator. All the dates have passed. What do these dates mean? Do I need to toss the foods?

Blightline August 28, 2014

Late blight has been reported in Benton County, MN, in commercial potatoes and been moving into additional fields in this area as a result of rains, high dew points, and cool weather. Growers in central MN should be scouting fields, applying fungicides to reduce tuber infection and killing fields to prevent further movement. Recommended fungicides to reduce tuber infection include Gavel, Omega and Ranman. Late blight is an explosive disease that can spread quickly in cool wet weather so it is important to keep the foliage protected with fungicides late in the season. We would appreciate receiving samples of late blight for genotype identification.

Blightline August 25, 2014

The late blight reported in Becker County was negative after laboratory testing. Growers should continue to apply protectant fungicides for both late blight and early blight and continue to scout for late blight. Morning dews that form this time of the year provide free moisture necessary for late blight infection. Late blight is an explosive disease that can spread quickly in cool wet weather so it is important to keep the foliage protected with fungicides late in the season.

Aphid Alert for Week Ending August 22

Aphid Alert for Week Ending August 22

Aphid vector numbers were up for A THIRD WEEK IN A ROW! Probably because the temperatures last week were excellent for aphid reproduction and numbers were increasing. This may well have led to an increase in winged aphids, resulting in higher trap catches. Trap catches increased at a number of locations over last week and decreased in some others. Numbers were up in Ada, Erskine, Hallock, Hoople, Langdon, Linton I, Perham, Staples, Stephen and Walhalla and down at other sites. Approximately 80 more aphids were recovered overall from all traps compared to last week.

Late Blight reported! Blightling Aug 20, 2014

Late blight has been reported in a field of Russet Burbank processing potatoes in Sherburne County, MN by a local consultant. Disease is confined to one field and incidence is limited. The genotype has not yet been identified. This is the first report of late bight in our region. Growers should continue to apply protectant fungicides for both late blight and early blight and continue to scout for late blight. Morning dews that form this time of the year provide free moisture necessary for late blight infection.

NPPGA Field Day set for August 21, 2014

The annual potato field day tour will travel to three locations - Larimore, Inkster and Hoople - on Aug. 21. The field day begins at 7 a.m. with breakfast at Hoverson Farms near Larimore. Research presentations will begin after breakfast. Lunch and research presentations will be given at the Forest River Colony near Inkster starting at noon. Following lunch, a field tour will highlight irrigated research trials. The twilight tour will be at Oberg Farms near Hoople starting at 5 p.m. This will include a barbecue and research presentations by North Dakota State University and University of Minnesota potato researchers and Extension specialists.

Aphid Alert II

Aphid Alert II

Aphid Alert II trap catches for the week ending Aug 15 are now available. Aphid vector numbers in seed potatoes took a huge jump this past week with capture numbers doubling at most locations! Vector species captured include lots of small grain aphids (not surprising given maturing small grains), green peach aphid from two locations, and soybean aphid from multiple locations. Aphid scouting and management should be well underway! If you're in a position to kill vines early, consider it. Most of our PVY is transmitted in the late season.

Blightline Aug 11

Late blight has not been reported in our region of ND, MN or MB. The late blight severity threshold value of 15 has been reached at all locations. For our conditions, application of a protectant fungicide such as mancozeb or chlorothalonil on a 7-10 day schedule is recommended.

Aphid Alert II: Aug 8. Aphid number are increasing rapidly!

Trap catches from the Aphid Alert II suction trap network are in for the week ending Aug 8. This has been one of the biggest capture weeks so far this summer. We had large increases in almost all trap locations over last week. If you have not started aphid management, it's time to start!
