to many people with hay fever. Common Ragweed emerges in the late spring, and sets seed in later summer or fall.
in some European countries , and in Japan, where it is known as butakusa —pig grass.
Common ragweed is a very competitive weed and can produce yield losses in soybeans as high as 30%. Control with night tillage reduces emergence by around 45%. Small grains in rotation will also suppress common ragweed if they are overseeded with clover. Otherwise, the ragweed will grow and mature and produce seed in the small grain stubble. Several herbicides are effective against common ragweed, although resistant populations are known to exist.

Lead
Lead is a main-group element in the carbon group with the symbol Pb and atomic number 82. Lead is a soft, malleable poor metal. It is also counted as one of the heavy metals. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed...
