Garden herbicides have become popular in recent years. Many people are puzzled. Isn't gardening a grass? Why do we weeding, weeding is to look more neat and unified, remove weeds and plant grass, what are the common garden herbicides? China's pesticide network has compiled 12 common herbicides from the network as follows:
First, a lot of spring:
It is a new type of systemic non-selective post-emergence herbicide for systemic conduction. It mainly inhibits the conversion of prionin to phenylpropionic acid, tyrosine and tryptophan by inhibiting the enol acetone quinone and phosphorylation synthase in plants, causing the synthesis of proteins to be disturbed and leading to death.
Spring has many of the following characteristics:
1. Broad-spectrum: It can control monocotyledonous and dicotyledonous, annual and perennial, herbaceous and shrub plants.
2, systemic: can be quickly absorbed by the stems and leaves of plants, conduction up and down, the destruction of the underground tissue of perennial weeds is very strong.
3, thorough: can kill roots, weeding thoroughly.
4, safety: low toxicity to mammals, no significant impact on fish.
5. Residual: Once in the soil, it will soon be combined with metal ions such as iron and aluminum to passivate, which has no adverse effects on the seeds and soil microorganisms in the soil.
6, long-term effect: the use of a lot of spring, more than the use of other types of herbicides , saving time, labor and money.
7. Mixability: It can be mixed with herbicides such as grass and fruit, and it can prevent weed damage. The main weakness: no single weeds have no preventive effect on ungerminated weeds.
Second, the cutting grass (Gore):
It is a selective contact-type soil treatment herbicide. Its main features:
1, a wide range of killing grass: before or after the bud can kill a variety of weeds, especially to kill a variety of broadleaf grass.
2. Applicable to many species of trees.
3. Long application period: The pre-emergence weeds are mainly controlled by the soil treatment method, and the weeds can be removed by the stem and leaf spray method in the weed seedling stage, and the liquid medicine falling into the soil at the same time as the weeds are eliminated. It is also possible to control weeds that have not yet sprouted.
4. Safe for trees.
5. No residual pollution.
6, the toxicity is extremely low.
7, easy to use, can be mixed with spring, grass can be mixed.
The main weakness: poor control of grass weeds.
Third, cover grass can:
It is a highly selective post-emergence herbicide. main feature:
1. It can be absorbed by the weed leaves and transmitted to the whole plant to make it die.
2. It is stable in nature and has a long residual effect in the soil.
3, can be used for stem and leaf treatment, but also for soil treatment, when the stem and leaf treatment, the liquid spilled into the soil still kills grass.
4, can effectively prevent grass weeds.
The main weakness: invalid for broadleaf weeds.
Fourth, spring cover fruit mixture:
It is a mixture of three kinds of herbicides, which are mixed with a certain proportion of spring herbicides and grasses. It not only exerts the superiority of each of the three herbicides, but also overcomes their respective weaknesses. Main features:
1. Spraying in the vigorous period of weeds, which plays the role of double treatment of stems and leaves and soil. It is especially suitable for weeding in large seedling nurseries, young forests and depressions, and leisurely, to achieve the dual functions of weeding and grass protection.
2, for grasses, broadleaf weeds can be prevented.
3, the grass killing rate is extremely high, especially for the malignant grass.
Five, cover fruit mixture:
It is a mixture of two kinds of herbicides, including grass and energy. main feature:
1. It can be used in the early stage of weed germination. It is mainly treated with soil treatment and grass control, supplemented by stem and leaf treatment and weeding. It is suitable for use in changing bed nursery.
2, for grasses, broadleaf weeds can be prevented.
3. Directional spray is safe for seedlings.
Sixth, four seasons:
It is a pre-emergence soil treatment agent that can prevent ryegrass turf broadleaf and grasses.
Seven, gram ethyl butyl mixture:
It is a mixture of gram, acetochlor and butachlor.
1, gram without trace: is a broad-spectrum contact-type stem and leaf treatment herbicide, can kill most grass and broadleaf grass, half an hour after the application of rain, the efficacy is not affected, only for green tissue.
2, acetochlor: is a selective pre-emergence dry soil treatment herbicide, can control annual grass and some dicotyledon.
3, butachlor: is a selective pre-emergence paddy field soil treatment herbicide, can control annual grass, sedge grass and some dicotyledon.
The above three herbicides can be mixed, and the stems and leaves and soil can be treated at the same time to prevent dry fields and paddy fields; grasses, sedges and broadleaf grasses; annual and perennial grasses.
Eight, Mori grass net:
It is a systemic high-efficiency herbicide with pre-emergence and post-emergence herbicidal activity. It can kill grass, can also inhibit seed germination, less dosage, wide spectrum of killing grass, long-lasting effect, once used, can maintain no grass in 1-2 years. It is an excellent herbicide for some conifer seedling beds, young coniferous forests and non-cultivated land.
Nine, rushing grass:
The endocrine-conducting herbicide is mainly absorbed by the plant roots and transported to the aerial parts. It can also be absorbed by the leaf surface and transmitted to the whole plant, inhibiting the photosynthesis of the plants, hindering the plants from producing nutrients and starving the plants. After sowing, the annual weeds in the pre-emergence or in the garden are in the early stage of germination, and the application of 1-2 leaves is good. It can prevent annual grasses, sedge weeds, broadleaf weeds and some perennial weeds.
X. Glyphosate:
It is a systemic broad-spectrum herbicide for internal absorption. Suitable for spraying under the nursery trails and garden trees, its characteristics:
1. The herbicide spectrum is extremely wide: it can kill more than forty varieties of weeds, and the best control effect is narrow-leaf weeds (such as grasses and sedges). Some foliar waxy layers such as Leguminosae, Liliaceae, Teaaceae, and Polygonaceae have strong resistance to plants, and have poor control effects on mixed bamboo and mango.
2, to prevent the forest land Baimao, Wujiemang, Damang, vegetable fern effect is good, can scribble the roots.
3. The price is low and the economic benefits are significant.
4, no environmental pollution, no impact on the hidden seeds and soil microorganisms in the soil.
5, to spray on the weeds, otherwise it is easy to produce phytotoxicity, not suitable for spraying in the seedling bed. 　
Eleven, fine grass grass grams:
The systemic selective herbicide, which is specially used to control the stem and leaf herbicides of grass weeds, is ineffective against broadleaf and sedge weeds. For various reasons, we missed the chemical weeding of weeds in the germination stage, and weeds can be used to control weeds.
Twelve, trifluralin:
It has both contact and systemic effects. It is a herbicide for soil treatment before or after seeding. It can be used for weeding in garden nurseries. It can control perennial weeds and some broad-leaved weeds of weeds and seeds in the first year of life. It has poor or ineffective effects on the control of Xanthium, Aconite and Bermudagrass; it is not effective for unearthed weeds. Generally, the soil is uniformly sprayed before the weeds are unearthed, and then the soil is mixed and mixed in the soil layer of 3-5 cm deep. In the drought season, it is also suppressed to prevent the chemicals from volatilizing, photolysis, and reduction. Pharmacodynamics.
