PEST MANAGEMENT

Tips on taking care of pests for fall crops

Spider mites have been found to be in our area says GCC Sales Manager and Agronomist Kyle Korf.  Scouting fields now and applying miticide early is the best way to keep colonies under control before they have been well established above the ear leaves.  Once mite pressure gets going, Korf cautions it is difficult to slow them down with a miticide.  There is some good news however.  

The recent rains our area has received and cooler temps have slowed mite populations down, but as temperatures begin climbing back into the 90's and we head back into a drier pattern, we're likely to see those numbers dramatically increase.  For those who have yet to apply miticide to their fields, farmers have a small window of opportunity to get that done, Korf said in a phone interview.  

Grasshoppers are another pest that have been observed in areas and as Korf explains, "Crops should be monitored for grasshoppers especially around edges bordering grass, pastures, CRP and even weedy road ditches."  Grasshoppers start in these areas and work their way into fields causing significant damage to crops.\

There are many options for controlling grasshoppers and the type of pesticide used will depend on what stage of the life cycle the grasshoppers are in as well as what crop they are damaging, says Korf.  Being that they are getting larger at this point it is recommended to apply at the upper end of the labeled rates of the pesticide product being used.  Some options to consider stem from pyrethroid family of pesticides as well as in combination with chlorpyrifos.  Dimilin and Prevathon are a couple pesticides that have proven effective against grasshoppers.  

Finally, be on the lookout for sugarcane aphids.  Though impossible to predict the level of infestation, if you are growing milo, scout regularly and often to check for their presence.  Currently sugarcane aphid pressure has been observed in the North Texas panhandle, central Oklahoma and a couple counties in South Central Kansas.
