Management of Insect and Mite Pests in Small Grains

Several arthropod pests damage small grains sporadically throughout the region. Pesticides should not be a substitute for good agronomic practices or used as “preventative insurance”. Pesticide misuse can cause pest resurgence issues and is rarely economically or environmentally justifiable. Many small grain pest problems can be managed by using good cultural practices, such as selecting varieties that are adapted to Oklahoma growing conditions, planting at an optimal date and providing proper fertilization and good weed control.

 

The information herein is for educational purposes only. Reference to commercial products or trade names is made with the understanding that no discrimination is intended and no endorsement by the Cooperative Extension Service is implied.

 

Pesticide recommendations in this publication were correct as of the “Modified Date" but always check the label that came with the purchased insecticide for the most current rates and restrictions

 

The first name listed is the trade name of a product registered for use in corn for the listed pest. The name in (parentheses) listed below the trade name is the name of the active ingredient. The active ingredient name is provided because in many cases, there are other registered products containing the same active ingredient that may cost less, so producers should compare prices.

 

The number [in brackets] following a product is its Mode of Action number [MOA]. The more frequently insecticides with the same MOA are used, the more likely resistance could occur. This number provides an easy way to select different modes of action to avoid selecting for pests that are resistant to a certain mode of action.


Refer to the following OSU publications for additional information.

Threshold: No established threshold. Delayed planting will reduce the incidence of Hessian fly infestations, but there is no established "fly free" planting date for most of Oklahoma. Some wheat varieties are resistant to the common Hessian fly biotypes (A, B, C and D) found in Oklahoma.

 

See EPP-7086 Hessian Fly Management in Oklahoma Winter Wheat

Wheat curl mite      
Tiny sausage-shaped mites that feed on leaves and heads. No effective chemical control is registered.   Delayed planting and management of volunteer wheat may reduce problems.

White grub      
“C” shaped whitish grub with a tan head and swollen tip of abdomen, measuring up to 1½ inches. No effective chemical control is registered.   While there is no effective insecticide registered for white grub control, systemic seed treatments such as Gaucho or Cruiser may provide some suppression because they are labeled for control of white grubs in other crops; however, there is no Oklahoma data to support that possibility.
Damage: Feed on roots. Cause
stand loss, poor emergence
and thin stands.

Damage: Leaves appear stunted and silver colored.     *Other products, such as dimethoate (Dimate and others) and chlorpyrifos (Lorsban, Whirlwind and others) can be applied under 2ee regulations, however since this pest is not specifically labeled, the user assumes all responsibility for the application and results.
Threshold: No established threshold; treat if injury symptoms and mites are present. Day time temperatures that exceed 75 F will reduce populations.      
For more information, see
EPP-7093 Mites in Small Grains.

* Group numbers in brackets [#] preceding the insecticide name are used to designate the mode of action of the insecticide according to the classification system developed by the Insecticide Resistance Action Committee, (IRAC). It is intended to help in the selection of insecticides for preventative resistance management. If you make multiple applications for a specific pest during a growing season, simply select a registered insecticide with a different number for each application. To further delay resistance from developing, integrate other control methods into your pest management programs.
