Biological Control of Pests in High Tunnels

Major insect and mite pests in high tunnels include aphids, thrips, white flies, and spider mites. Biological control uses living organisms (natural enemies) to suppress or limit pest populations to levels that do not cause economic injury to the crop.

Double-Crop after Wheat?

Two crops in one year may sound tempting, and for some crop species is possible, but before doing so, producers should consider possible crops and compare the potential benefits with the drawbacks.

Aquaculture Comes to South Dakota: Part 1

Aquaculture has expanded beyond Asia, Central America and the farm ponds of southern states up north to South Dakota. Of course, fish production in South Dakota opens a new market for the state’s soybean farmers.

Pollinating Tomatoes in High Tunnels

In field-grown tomatoes the air movement is sufficient to vibrate flowers and achieve pollination. This is not generally true in the high tunnel because there is not sufficient natural wind to vibrate the flowers. High tunnel tomato growers should therefore pollinate their crop by other means.

White Grub Damage to Lawns

White grubs are root-infesting larvae that are the immature stages of scarab beetles. Grub-infested turfgrass may turn brown and die from drought stress due to the inability to take up water from loss of roots.

Active Leadership and Followership

Different cultures may each have their own slant on the traits and characteristics that add up to effective leadership but despite the differences, some commonalities do emerge.

How to Prevent Iron Deficiency in Spring Greenhouse Plants

At this time in the growing season, Iron (Fe) deficiency symptoms are appearing among bedding plants and other spring greenhouse plants. The main symptom of Iron (Fe) deficiency is Chlorosis or yellowing, usually starting at the shoot tip and newly developed leaves.

Sore Mouth: A “Pox” Virus for Sheep

Just like in children or adults who contract the dreaded chicken pox, sheep and goats can catch their own similar “pox” virus called Sore Mouth, technically known as Contagious Ecthyma. This health problem is most recognizable by red blisters or thick brown scabs on the skin around the lips or muzzle area.

Scouting Wheat Fields

Scouting is the process of monitoring fields and crops during a growing season. It can provide producers with field specific information on pest pressure and crop injury.

Public Perception and Animal Well-Being

So you ask why is public perception and animal well-being important? Well, did you know that there is just a little over 1% of the population involved in production agriculture, today? Did you know that 98% of the people have no direct connection with how their food is produced?
