SDSU Extension publishes the South Dakota Pest & Crop Newsletter to provide growers, producers, crop consultants, and others involved in crop production with timely news pertinent to management of pests, diseases, and weeds in South Dakota.
Large grasshopper populations have been observed in Central South Dakota. These populations have required management in other crops and should be monitored prior to and during winter wheat planting.
As wheat harvest is underway it is important to ensure that grain bins are prepared in the best possible manner to prevent insect infestations. There are seven steps that can be taken to help reduce the chances of having infested grain.
During the end of last week, we received reports of grasshoppers feeding on winter wheat that was close to being ready to harvest. One of the questions with the report was, “What insecticide can be sprayed that won’t delay harvest?”
Slug activity in wheat fields has been reported in South Dakota. Although slugs are not normally an issue in South Dakota crops, they can pose a threat when field conditions are just right.
During most years, we start worrying about true armyworm activity in wheat fields in mid-July. However, the strong southerly winds that we experienced during the last two weeks pushed several insect pests north ahead of their normal schedule
Last week, we published an article about the presence of western bean cutworm moths being very abundant throughout Central and Western South Dakota. However, when talking with an entomologist from a neighboring state, they suggested the moths could also be army cutworm moths.
Reports of aphid populations in wheat fields have been slowly increasing in the past week. Most of these populations are well below the economic threshold, but there is a potential for them to increase.
Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.
