Alfalfa Weevil Activity Prediction Update: June 5, 2024
Although the degree day estimates suggest that alfalfa weevils are no longer active in the fields and should be pupating, scouting has indicated otherwise.
South Dakota Grasshopper Prediction for 2025
In 2025, it is likely that grasshopper populations will once again reach levels capable of causing issues in some areas of the state. Scouting should begin shortly after planting in areas where they were problematic in 2024 and continue throughout the growing season.
Black Grass Bug Activity Ramping Up
Black grass bugs feed on fresh green growth, which can result in stunted plants and decreased forage quality. Monitoring and potential management of black grass bugs will be of increased importance this spring, especially if drought persists.
Spring is here, and so are the ticks!
As spring continues to bloom, more arthropods will begin to emerge from winter dormancy. Ticks are among the first to appear, and statewide reports have already been flowing in.
Commercial Applicator Training for Pesticides
Those who apply pesticides for hire or as a government employee that applies pesticides while performing work duties, must have a commercial applicator license.
Managing Livestock for Dung Beetles and Other Beneficial Species
South Dakota researchers have taken a closer look at the function of dung beetles in Eastern South Dakota over the last few years. This article summarizes findings related to management of livestock grazing and chemical pesticides in relation to dung beetle and insect community health.
Rangeland Insects Are Critical Indicators of System Health
Insects, in general, may offer more indication of rangeland health than any other type of organism. They serve as key building blocks that other organisms depend on.
Understanding the Critical Role of Broadleaf Pollinator Plants in Pastures
Understanding the economic role of pollinators is the first step towards understanding their value to grassland and crop systems.
Insecticides for Protecting Pine Trees from Mountain Pine Beetle
There are no effective systemic pesticide treatments that will kill mountain pine beetle larvae inside the tree or adults as they emerge from an infested tree. Pesticide treatments are limited to protecting trees from becoming infested. These treatments are applied to the bark to kill the adult beetles as they land on the trunk and begin to burrow into the tree. This method of protection is highly effective and if the pesticides are applied at right time, losses may be as few as one or two trees for every hundred trees treated. However, only trees that are not infested should be treated. If a tree is already infested, pesticide application will not prevent the beetles from emerging and infested other trees.
Organic Pest Control Methods
Integrated pest management is an environmentally conscious approach to managing insects, weeds and disease. By focusing on natural processes, growers use pest control methods beginning with the least toxic and amplifying the pest control needs gradually if problems persist.
