Vegetative growth stages of corn or sorghum are determined by counting the number of fully emerged leaves with leaf collars present. This methodology can be used to anticipate growth and determine appropriate timing of many management decisions, including herbicide application, sidedress fertilizer, etc…. . . . → Read More: How to Determine Growth Stages of Young Corn or Sorghum
Over the last few weeks we have received numerous calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the stem or even down in the whorl of small corn plants. Typically the area where they feed becomes chlorotic due to enzymes in their saliva. . . . → Read More: Managing Stink Bugs in Seedling Corn
Abundant spring rainfall can create havoc with corn nitrogen management by delaying fertilizer application and also promote massive nitrogen loss. These strategies should help enhance crop response during challenging conditions. . . . → Read More: Use a Sound Corn Nitrogen Strategy to Combat Rainy Weather
Calls are starting to come in about stink bugs in heading wheat. It is not uncommon to find numerous stink bugs in wheat after head emergence. Species attacking wheat are typically rice stink bug and brown stink bugs but greens can sometimes be found. While it may seem very alarming, keep in mind it takes extremely high numbers to cause economic damage to heading wheat. . . . → Read More: High Stink Bug Numbers Being Reported in Some Heading Wheat Fields

I have recently received a few call about slugs in corn and soybeans. I suspect this will increase when more crops emerge in the Hill region of the state as well. Slug problems usually start on corn first, then move to soybeans, then cotton in our area. This is only because we typically plant in this order. Slugs have been a sporadic problem in MS row crops over the years with increased occurrence since 2004. This has been exclusively a no-till or reduced till problem, particularly no-till behind a grass crop like corn or grain sorghum. Cool wet years are particularly favorable for slug problems to develop. . . . → Read More: As Crops Emerge, Slug Calls Start
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and herbicide systems. There will be numerous hands on displays of insects, weeds, nutrient deficiencies in all major row crops, and fertilizer characteristics. CEU’s Provided: Nutrient Management = 1.5, Integrated Pest Management = 3, Crop Management = 1 . . . → Read More: 2015 Scout Schools Set for Mississippi
Much like the last 2-years, as rains delay corn planting progress, more concerns arise regarding whether you will have ample opportunity to plant your corn crop in a suitable time window. This article states new guidelines for late corn plantings based upon recent MSU research. . . . → Read More: Are We Going to Get this Corn Crop Planted?
