Tansy is a malignant weed with strong vitality and high reproduction rate. The most important thing is that the pollen from tansy can cause harm to the human body and trigger asthma. Therefore, while preventing and controlling tansy, we must also avoid the harm it causes to the human body!
The Hazards of Tansy
1. Tansy generally grows in large 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.
2. Tansy can spread diseases and pests. When tansy fruits are mixed with other plants, it can cause terrible spread of tansy.
3. Its pollen can induce hay fever and bronchial asthma, seriously endangering human health.
What to Do for Tansy Allergy?
First of all, avoid contact with tansy, as tansy allergy is the main pathogen of hay fever.
Pay attention to food hygiene and avoid fish, shrimp, seafood, and spicy foods. When experiencing tansy allergy, do not scratch with your hands to avoid worsening the allergic symptoms.
Typical symptoms of tansy allergy include severe itching in the body, especially in the ears, eyes, and nose, accompanied by runny nose and headache. Severe tansy allergy sufferers may develop emphysema and even die.
Methods to Eliminate Tansy
1. From late May to mid-June, before tansy blooms, pull it out from the root and then dry and burn it. This method is simple, feasible, and most thorough.
2. If a large area of tansy is found, use a herbicide containing 10% glyphosate to spray and eliminate it. The kill rate is above 90%.
3. In Russia, a specific beetle is used to prevent and control tansy, while in the United States, a white rust fungus is used for prevention and control.
