Managing Resistance Requires Multitude of Tools

If you are involved in agriculture, you have been inundated with information about resistance management. Most of the conversation is centered around herbicide and insecticide resistance that is occurring due to the ability of plants and insects to adapt over time to repeated applications of a similar active ingredient.  Many of the issues we deal [...]

What Is The Cost Of Saving Your Own Wheat Seed?

Many producers plan on saving back some wheat for seed.  This is partially a cost saving decision.  But the question is whether it truly is cheaper to save your own seed vs buying certified seed. Starting with a good quality clean seed at planting is one of the most important things we do.  We very [...]

Rootworm Strategies

June is the typical month for scouting western corn rootworm larvae in continuous corn fields of the high plains. Agronomists understand the damage that this pest can cause, and many hours are spent digging to examine the deep and brace roots for any signs of rootworm larvae feeding. Early detection is key to minimizing damage [...]

Dealing With Pill Bugs In No-till Soybeans

Pill bugs have become an issue in south central Kansas as we have transitioned away from tillage into no-till on our irrigated fields. Excess residue on the soil surface has created a perfect environment for pill bugs to thrive.  Pill bugs like moisture and cover, as they do not like to be exposed to direct [...]

Insect Resistance in Alfalfa

Weed and insect resistance to different kinds of pesticides continues to be a hot topic in agriculture. Most of us are aware of the resistance of glyphosate to a handful of common weeds.  About six years ago we started to see resistance on the alfalfa weevil with commonly used pyrethroid insecticides in alfalfa. Since then, [...]

Selecting Postemerge Herbicides

As crops, and of course weeds begin to emerge this spring, many producers may not be aware of the process their Crop Quest Agronomist uses to select appropriate herbicides for control of these weeds. There are a multitude of questions that need to be answered before a particular herbicide and timing of application can be [...]

Sugarcane Aphids

This past season, sugarcane aphids (also known as white sugarcane aphids) have migrated as far north as Oklahoma and Kansas. They have caused crop damage in some grain sorghum fields. Like other aphids, sugarcane aphids are a sucking pest, which can discolor and desiccate leaf tissue. They also deposit a thick honeydew like substance on [...]

Corn Borer & Late Season Pest in Corn

It is that time of year again when it becomes necessary to treat the late season lepidoptera species that can infest your corn crop. The most predominant pests this time of year are normally the two species of corn borer. These worms bore into the ear or the stalk of corn plants causing economic damage. [...]

Controlling Sunflower Stem Borer May Not Include the Use of an Insecticide

The ever increasing pest in sunflowers, the sunflower stem borer also called the soybean stem borer, is causing more damage and harvest loss to fields across sunflower producing areas. Many times you are not aware that you have a problem until you see plants lodging before harvest. Sometimes the damage may be confused with the [...]

The Illusion

Is it just me, or do skeptics of GMO crops just like to consume products that have been treated with more pesticides? We hear about the marketing schemes touting non-GMO, organic, gluten-free, sustainable agriculture, or whatever other buzzword that can be used to prey on what I believe is an uninformed consumer. I have no [...]

Alfalfa Weevil

Alfalfa weevil can cause major damage to alfalfa production during the early cuttings of the growing season.  Adult weevils lay their eggs inside the alfalfa stems in the late fall or early spring.  The hatched larvae then feed on the terminals and upper leaves of the alfalfa plant in the early spring where most of [...]

Applying Insecticides to Refuges

Bt (Bacillus thuringiensis) is a protein inserted into plant genes such as corn, that is toxic to certain insect pests.  Bt corn is used by many farmers and is very beneficial to the management of insect pests.  To avoid insect resistance to Bt genes there must be a nearby refuge.  The refuge is a similar [...]

Rootworm Control Can Be Complicated

The dynamics of managing rootworm larvae and adults has changed tremendously the past 10 to 15 years.  Before the onset of Bt Corn Rootworm (CRW) genetics, before the practice of controlling adults (beetle bombing) for the purpose of controlling next year’s larva population, granular soil insecticides were the norm, and were very effective. These events [...]

Corn Borer Control in a Bt World

Prior to the introduction of the Bt (Bacillus thuringiensis) gene in corn, it was common to treat the vast majority of corn acres in this country for European and/or Southwestern Corn Borer each summer.  In many areas, there are two, possibly three flights of the corn borer moth each year.  The second flight is usually [...]

Avoiding Insect And Weed Issues In Soybeans

Soybeans are a great option for producers to utilize in rotation.  Soybeans are not only good for the soil, they are also a good option to clean up fields for other crops in a rotation situation. To avoid weed pressure concerns, producers in Northeast Kansas tend to practice preventive treatments in the fall and early [...]
