This is the second article in the “World of Weeds” series. Kochia, also known as tumbleweed, is native to Europe and Asia and was introduced from Europe as an ornamental in the mid- to late- 1800s. It is well adapted to the Great Plains. Read more about this weed and why management is so important to Kansas farmers.
Now is the time to finalize plans for kochia control. Major flushes of kochia emerge in late February and continue through early April, resulting in dense populations that make adequate herbicide coverage difficult. It is important to apply pre-emergence herbicides in late winter or early spring to control this weed before it emerges.
Now is the time to finalize plans for kochia control. Recent research suggests that kochia can begin emerging in early February with most kochia emerging by early April. This article will be the first in a series discussing specific options for various cropping systems.
Last week, we shared some general information about applying pre-emergence herbicides for kochia control. In this article, the focus is on specific recommendations for fields going to corn or grain sorghum this growing season.
This is the third and final article in a series discussing pre-emergence herbicides for kochia control. For this article, we cover recommendations specific to fields that will be planted to soybean or sunflower this spring and wheat in the fall.
Post-harvest weed control in wheat stubble is very important to conserve soil moisture and prevent weeds from going to seed and adding to the weed seedbank. Weeds can grow quickly once the wheat canopy is removed.
