Prevention – Learn to identify plants; know your property; control kochia along fencelines and roadways to reduce seed scatter by tumbling plants
Biological – No known biological controls
Cultural – Competitive vegetation helps avoid invasion and winter wheat withstands kochia better than spring wheat
Mechanical – Grazing and mowing will not stop seed production or kill the plant which will resprout from the stem; pull, hoe or cultivate to kill kochia; shallow tillage helps force seeds to sprout or decay
Chemical – Several effective at label rates, but kochia is often resistant to triazine & sulfonylurea herbicides; rotating herbicides with different modes of action helps prevent resistancedevelopment
kochia seedlings can form a solid mat
Where found - Limited numbers of plants but widely scattered distribution in Stevens County; mainly along roadsides, railroad, parking lots, gravel pits and piles, other highly disturbed sites.
