Solidago canadensis is a perennial plant with developed rhizome, strong reproduction and rapid spread, which will also bring certain harm to the ecological environment. There are many control methods of Solidago canadensis, such as direct removal, incineration or chemical agents.
1, uprooted directly: this method can also be said to be weeding. Generally, it is necessary to uproot the whole Solidago when the seeds are immature, and then remove the asexual reproductive organs such as rhizomes remaining in the soil by intertillage. It should be noted here that uprooted plants need to be burned in time.
2. Incineration: Incineration is relatively simple, but not thorough, because there is no way to completely remove the underground reproductive organs, so it is best to pull out the aboveground parts and tubers, but it must be burned in time, because the reproduction speed of yellow flowers is very fast.
3. Pesticides: So far, using pesticides for control is also an economical and effective method, especially in seedling stage or adult stage, the effect of using pesticides for control will be better.

What exactly is a Canadian goldenrod?
Solidago canadensis belongs to Compositae of Campanulaceae, also known as oriole and Eucheuma. This is a perennial herb with long stems and roots, which are basically upright and can reach 2.5 meters in height. Its leaves are generally lanceolate or linear lanceolate, about 5- 12 cm long.
Solidago canadensis L. has bright flower shapes and colors, and is generally used for flower arrangement. It is also a strange creature. 1935 was introduced to China as an ornamental plant for the first time, but because of its special properties, it gradually produced malignant weeds, which were common in floodplains and wasteland. Because it is a perennial plant, its rhizome is very developed, its reproductive ability is strong and its spread speed is very fast.
