【Hazards of Tatami Grass to Plants】
1. Nutrient absorption
Tatami grass usually grows in dense clusters and has strong regenerative and reproductive abilities. It not only makes the soil dry and infertile, but also blocks sunlight due to its tall stature, making it difficult for other plants to grow and reproduce. Its strong reproductive ability makes it difficult to eradicate once it has grown.
2. Spread of diseases and pests
Do you know what causes sunflower leaf spot disease and soybean pests? One of the reasons is tatami grass. This is another hazard of tatami grass, as it can spread diseases and pests.
When tatami grass fruits are mixed with other plants, it can lead to the terrifying spread of tatami grass. For example, cabbage clubroot disease is caused by tatami grass.

Tatami grass is a global environmental pollution plant. Due to its strong vitality, it can cover and suppress native plants, causing damage to the original ecosystem, reducing agricultural yields, depleting water and nutrients in the soil, and causing air pollution from pollen. It is a harmful plant.
Various types of tatami grass, especially the pollen of giant tatami grass, can cause allergies and are common allergens. Pollen is lightweight and small in size, easily carried by the wind, and has many spines on its surface, making it easy to attach to the respiratory mucosa.
Tatami grass allergies are also the main cause of hay fever. People with tatami grass allergies may experience intense itching, especially in the ears, eyes, and nose, accompanied by runny nose, headache, and other symptoms.
Every summer and autumn, a large amount of pollen pollutes the air, causing allergic asthma. Severe tatami grass allergies can lead to emphysema and even death.

【Differences Between Tatami Grass and Mugwort】
1. Appearance
Tatami grass looks very similar to mugwort. The difference is that mugwort has gray-white short hairs on the back of its leaves, and its leaves are opposite each other, while tatami grass leaves are dark green on the top and light green on the back, with short rough hairs on both sides.
2. Odor
Mugwort has a distinctive strong aroma, while tatami grass has a repulsive grassy odor. Tatami grass is easily confused with mugwort, but it has certain harm to cultivated plants, wild plants, and human health.
It is understood that tatami grass is highly invasive and harms the growth of crops and other annual herbaceous plants in the Asteraceae and Poaceae families. It releases various substances that inhibit the normal growth and development of cultivated and wild plants.
Its pollen contains allergenic substances, which can cause "hay fever," harmful to human health. Mild symptoms include coughing and asthma, while severe cases can lead to emphysema and even life-threatening conditions.
