Southwestern corn borer moths are starting pick up in traps in some areas of the state. At this time the hotspots appear to be around Lee county and north Jefferson county. We expected with the early spring and hot weather this season that this emergence might occur a little earlier than usual, but it Continue reading Corn insect update: Southwestern corn borers emerging We’re beginning to see midge in a few grain sorghum fields. Particularly in areas with a lot of Johnson grass growing near the field. Sorghum midge is a tiny orange colored fly that only attacks sorghum during flowering. So any sorghum that is flowering should be scouted for this insect. Because midge only attacks Continue reading Watch for midge in flowering grain sorghum We are getting an increasing numbers of calls about cutworms showing up in corn. It appears that there are several species showing up in corn fields this year. We have seen both black cutworms as well as variegated cutworms in the same field. Cutworms tend to be worse in minimum or no-till fields, particularly Continue reading Cutworms Showing Up In Corn I’m getting a lot of calls about yellowstriped armyworms in soybeans in NE Arkansas. They seem to be worse in fields with small plants, particularly double-crop soybeans planted behind wheat. In most cases, the caterpillars are still pretty small and not causing much defoliation yet. Some fields also have a few corn earworms Continue reading Yellowstriped Armyworms in Soybeans We’re seeing high numbers of Japanese beetles in some corn fields in Western Arkansas. In some instances, these beetles are feeding on and removing most of the silks on pollinating corn. Most of this damage is spotty and usually near field edges. Growers in the western portion of the state, where Japanese beetles Continue reading Japanese Beetles Clipping Silks in Field Corn in Western Arkansas Wheat harvest is just around the corner and some growers will be storing their harvest on farm in bins for an extended period of time. Recent heavy rains have kept some growers out of the field and now would be an excellent time to prepare bins for storage. Stored grain pests can cause significant Continue reading Bin Sanitation – The First Step in Preventing Stored Grain Insects True armyworms are showing up in high numbers in wheat in south Arkansas at this time. True armyworms are a threat to wheat when heading starts to occur. Wheat is very attractive to the armyworm and thick, vigorously growing fields can attract high infestations. True armyworms prefer to feed on the leaves of Continue reading True Armyworms Feeding on Wheat We are getting reports of sugarcane beetles in seedling corn in some areas. Right now we are seeing them in southwest Arkansas, but growers in other areas should be watching for these pests. Adult sugarcane beetles are hard, shiny black beetles found in seedling corn feeding at or just below the soil level. Continue reading Sugarcane Beetles Showing up in Seedling Corn Chinch Bugs are showing up in high numbers in seedling corn and rice in Arkansas. Chinch bugs are one of those insects that can sneak up on a grower and cause significant damage. They feed on grasses, so corn, grain sorghum and rice are the crops we are primarily concerned with when it Continue reading Chinch Bugs In Corn and Rice There are several different species of aphids that can be found infesting wheat. The two that most commonly occur in Arkansas are the bird cherry-oat aphid and the corn leaf aphid. Even though these two species can reach high numbers in wheat, they seldom cause significant economic damage. Treatment is not recommended unless numbers Continue reading Aphids in Wheat |
