John Thobe, EA-IPM Parmer, Bailey, and Castro has confirmed ‘red mites’ in Castro County late field corn this week. We will need to add this pest to our scouting preparation for next season. They do tend to behave more like a Banks grass mite but are most likely closer kin to two-spotted mites, except they have proven harder to control north of Amarillo and into Kansas where this pest has been active for several growing seasons. Now that they are in our area, we will be working on finding the best treatment options locally, building on and hopefully just adapting control measures proven by our friends to the north to our area next year. Stay tuned folks…

Here’s this week’s High Plains IPM “Radio” Podcast for 9/15/2021. Cotton: insects almost done but stink bugs and aphids still a threat. Corn: southern rust, gray leaf spot and spider mites still on the radar. Sorghum: late blooming fields still subject to midge. Sugarcane aphid, lygus and stink bugs can still do harm. Note this year's problems to help next year. (7:40)

Here’s this week’s High Plains IPM “Radio” Podcast for 9/8/2021. Cotton: heat units welcome, rain needed, Lygus still active on young fruit, bollworms fading, stink bugs still a threat. Allow some stress after last harvestable boll is 20 days old. Sorghum: headworms, midge and sugarcane aphid still need watching. (5:35 mins).
