Kochia is a kind of invasive weed. If not properly controlled, it can spread extensively and cause serious harm to the ecological environment and human health. Therefore, it is important to learn how to control kochia. Today, let's learn about the methods of controlling kochia!

The dangers of kochia
1. Ecological destruction
Kochia can become a dominant species one year after invading bare land. Due to its strong vitality, it can cover and suppress native plants, causing damage to the original ecosystem, reducing agricultural output, depleting water and nutrients in the soil, and causing significant agricultural losses. The spread of kochia can lead to large areas of land being left fallow, posing a major threat to the ecological environment.
The potential harm of kochia is particularly serious in extensive agricultural areas. Kochia can mix with all dryland crops, especially intercropped crops such as corn, soybeans, sunflowers, hemp, and flax. It can cause a large area of crop failure, resulting in a complete loss of harvest.
2. Pollen allergies
The direct harm of kochia to the human body is the pollen it releases after flowering. The pollen contains water-soluble proteins, which are released rapidly upon contact with humans, causing allergic reactions. It is the main pathogen causing autumn pollen allergies and can cause the harmful "hay fever" effect on health.
Mild cases can cause coughing and asthma; in severe cases, it can cause emphysema, and once infected, it can recur annually and worsen every year.

Therefore, experts remind us not to touch the flowering three-lobed kochia. Three-lobed kochia also poses great harm to agriculture.
Due to kochia's strong root system and large above-ground nutrient body, it grows vigorously and competes with crops for water and nutrients. It releases various substances that have obvious inhibitory effects on cultivated crops and wild plants, quickly overwhelming local annual plants.
Methods of controlling kochia
Kochia has spread extensively, causing serious harm to the ecological environment and human health. Faced with its aggressive invasion, experts urgently call for increased efforts to control kochia.
Kochia can quickly form a single dominant community in an area, occupying the living space, nutrients, and water of other plants, leading to the decline and extinction of the original plant community.
It is reported that in the 1980s, Jiangxi Province conducted weed control in various counties and districts, achieving certain results.

However, at that time, only chemical and manual removal methods were used to deal with kochia, which appeared powerless in the face of its strong reproductive and survival ability.
Kochia expert Kovalev from the former Soviet Union once pointed out, "If China does not take urgent measures to control kochia, the consequences will be irreparable."
In terms of control methods, plants also follow the principle of survival of the fittest. In terms of control methods, chemical methods are effective but highly polluting. Experts recommend using biological methods to control kochia.
It is understood that kochia has the growth characteristic of "seizing every opportunity". As long as there is open land, it will quickly occupy it.
Experts suggest combining urban greening and selecting plants with strong competitiveness to "encircle and intercept" kochia, occupying urban open spaces. Planting economically competitive plants such as ginger would be a good method of control.
