Lesser flowering grasses, Amaranthaceae, belong to one year growing herb. According to statistics, the young scabies can scrape about 200 grams of belly hair and leg hair from each sheep each year. The loss of wool amounts to more than 1,000 kilograms a year, equivalent to more than 10,000 yuan, and each year picks out less flowers from the wool. The labor fee for grass thorns is about 10,000 yuan. The thorny hedgehog spends more than 2,000 kilograms of wool each year, worth more than 20,000 yuan. It only causes losses of more than 40,000 yuan per year.
The vitality of L. edulis is very strong. After being introduced into a certain section, it can rapidly breed. It competes with other pastures to compete for water, compete for fertilizer, and inhibit the growth of other pastures. As a result, the quality of pastures is reduced, and the yield of excellent pastures is reduced. Seedlings of various herbivorous animals eat no harm. During the mature stage of seed setting, the fruit has a sting and the mouth is formed. The herbivorous livestock eats mature thorns and sticks to the side walls of digestive tract such as stomach and stomach, and is surrounded by mucous membranes to form nodules, affecting normal digestion and absorption functions. Causes the carcass to be thin, and can cause gastrointestinal perforation to cause death. Postmortem examination of the stomach has hairballs of varying sizes, and there are a large number of grasshopper nodules of varying sizes on the intestinal wall. Thorn bag mixed into the skin to reduce product quality and reduce the economic benefits of raising livestock.

At the same time, the seeds with burrs from flowering grasses to ripening have endangered people's production and life. Farmland, grasslands and forests are everywhere. The burrs that puncture the body left them inflamed, and they will heal in a few days.
Control methods: Sphaerotheca fuliginea can be used as pasture for livestock before grazing. Farmers and herdsmen can grazing livestock and poultry to reduce the damage during the seedling stage of compositae. Pastures can also be planted to inhibit the growth of Spartina. It is also possible to manually eradicate when flowering is not a result. The most effective method is the use of chemical agents, foliar spray control, 30 liters of water per acre. The prevention and treatment time is in the 3-4 leaf stage of L. edulis (around June 10), and 5% of leisure oil (80 ml/mu) and 41% of Yunon Si (400 ml/mu) can be used. 4 Percentage of Yu Nong Music Suspension (100 ml/Mu), 25% Constance Oil Suspension (180 ml/Mu), Red Emulsion, Refined Emu Emulsion, Jingkui and Ling Emulsion, all of which are good Control effect.
