A treatment schedule with 2,4-D is a way of killing knapweed. The application must be made in October and November for the best chance of success. Even under the best of treatment schedules, it will be difficult to control the Centaurea genus member in question even though any two of controlled burn, extreme cutting and pesticide schedules tend to eliminate any non-woody or woody plant within one to three years.

What are ways in which spotted knapweed is not a pest?
Acting as a ground cover, contributing to soil phosphorus levels, functioning as a natural herbicide, providing floral color, and supporting native plants (Gaillardia grandiflora, Lupinus sericeus) are ways in which spotted knapweed (Centaurea maculosa) is not a pest. But at the same time, spotted knapweed fundamentally fits the pest bill for disagreeing with grazing sheep, dominating space, endangering neighboring plants through catechin-allelopathy grabbing water through a super-effective tap root, out-competing native bunchgrass, producing many seeds, and outwitting biological controls.
Why is knapweed the national flower of Germany?
"Bright and cheerful, the bright blue of the knapweed or cornflower is pretty among the rolling green hills of Germany. The state flower of Germany is the cornflower, locally called the knapweed, and with the distinction come a few interesting local traditions.

Why do invasive species produce seeds?
If they are plants (e.g. spotted knapweed) they produce seeds to reproduce, because they are plants that produce seeds to reproduce. If they are animals (e.g. brown tree snake) they do not produce seeds, because animals do not reproduce by producing seeds.
What are some allelopathic plants?
Alleleopathic plants are those that alters or prevents the growth of other plants either through chemical processes, or through plant physiology. Some known allelopathic plants are Russian knapweed and diffuse knapweed that alter growth of other plants through the release of chemicals within the root zone. Smooth brome, Russian olive, cheatgrass, and other very invasive species could also be considered alleleopathic species since they either alter how other plants grow, or they prevent the growth of other plants all together through competition for sunlight and moisture. Hope this helps.
