Cover Crops in Potatoes

Cover Crops in Potatoes

Cover crops are plants grown between cash crops for the purpose of soil conservation. Cover crops reduce erosion from wind and water, and over time will improve and maintain soil organic matter and soil health. Additionally, cover crops may aid in pest management, increase soil biodiversity and carbon, reduce loss of nutrients, and can increase nutrient availability. In many cases, cover crops have been shown to increase yields of cash crops.

Potato Tuber Second Growth

Potato Tuber Second Growth

Potato tubers are the result of the plant genetics and the environmental conditions in which they are grown. Potato varieties are selected carefully for tubers that have desirable appearance to maximize sales and reduce waste. However, some years can cause more environmental stress than others, resulting in tuber secondary growth. Secondary growth often manifests as heat sprouts, tuber chaining and tuber malformations. This physiological disorder decreases yield and quality of the tubers in the field.

Spud Scoop, September 12, 2020

Welcome to Spud Scoop for the week ending on September 12, 2020. No late blight has been reported in ND, MN and MB. This week no late blight spores were found in the spore traps. Aphid vectors were down at all locations this week with cooler temperatures slowing down reproduction and movement. With multiple nights of freezing temperatures, potato vines in many areas have died. Because of this we will be ending the spore trapping network and this newsletter for this growing season. The cooler temperatures have provided favorable harvest conditions. Ideal tuber pulp temperature for harvest is 45 to 65 F. Yesterday was 9/11, and as Dr. Ian MacRae said “let’s take a moment to remember those brave individuals who run towards danger in order to safeguard us all.” Have a happy and safe harvest!

Welcome to Spud Scoop for the week ending on September 5, 2020. No late blight has been reported in ND, MN and MB. Congratulations to everyone in the potato industry in our area. Stay diligent with fungicide protection and scouting fields as harvest approaches. This week no late blight spores were found in the spore traps. Aphid numbers were down this week buy they’re still flying. Green peach aphids are more dispersed being found in 10 of 19 sites. Good luck with harvest as it gets into full swing.

Stay diligent with fungicide protection and scouting fields as harvest approaches. This week no late blight spores were found in the spore traps. The spore trapping network is winding down as harvest is beginning.

Welcome to Spud Scoop for the week ending on August 22, 2020. No late blight has been found in ND, MN or MB. Late blight spores were found in Cavalier, ND and in Little Falls and Rice, MN. Stay diligent with fungicide protection and scouting fields. We had another big week for aphid vector numbers, with very similar numbers to last week. A total of 287 vectors were recovered from 15 sites reporting. In fact, with this week's catch, we've caught up with 2019 and are pretty much at the same levels, but with different levels at different sites.

Hi and welcome to Spud Scoop! Late blight was confirmed in Wisconsin and genotyped as US-23. No late blight spores were found in the traps this week. Aphid numbers took an even bigger jump this week with the vector numbers and the PVY Vector Risk Index tripling over last week. A number of efficient vectors were found at most locations, including Green Peach Aphids being recovered from both the Crookston and Hoople traps.
