What pesticides are good at weeding?

Herbicides with good herbicide effect are: glyphosate, paraquat, steady killing, and napujing. The effect of these herbicides is relatively good, and the effect can be achieved basically at one time.

Herbicides refer to agents that can cause weeds to die completely or selectively, also known as herbicides, to eliminate or inhibit the growth of plants. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have a dead effect on any kind of plants, and their effects are affected by three factors: herbicides, plants and environmental conditions. According to the function, it is divided into incidal and selective herbicides, and most of the selective herbicides, especially nitrophenol, chlorophenol, and carbamate derivatives, are effective.

The development of herbicides in the world has gradually stabilized, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosage, and disposable treatment agents with little environmental pollution have gradually become the mainstream.

Pesticides with good herbicidal effect are: glyphosate, flulelin, glufosinate-ammonium, methylphenyl ether, etc.

Glyphosate: This is a broad-spectrum, highly effective herbicide that kills most herbaceous plants and some woody plants. Its advantage is that it will not cause harm to crops, and it is not easy to be adsorbed and decomposed by the soil, and can maintain the weedicidal effect for a long time.

Flulelin: This is an alternative to glyphosate that also has a broad-spectrum, highly effective herbicidal effect. Compared with glyphosate, fluoralin kills herbs faster, but it has a greater impact on the soil, which is easy to cause soil acidification and microbial death.

Glufosinate-ammonium: This is a new type of herbicide that kills herbaceous plants through foliar uptake and root uptake. Compared with glyphosate, glufosinate ammonium has a more significant herbicidal effect and does not have much impact on the soil.

Methyl phenyl ether: This is an organophosphate herbicide that is mainly used to kill some herbaceous plants that are difficult to kill by other herbicides. Its advantage is that the herbicidal effect is remarkable, but its impact on the environment is large, and it is easy to cause soil and water pollution.

Please note that the use of pesticides must comply with relevant laws, regulations and prescribed operating procedures to ensure safety and avoid adverse effects on the environment and crops.

The most powerful herbicide: Proud Kill, an industrial herbicide variety.

It is a systemic conductive herbicide, which is absorbed through the roots, stems and leaves of weeds, and then conducts up and down in the weed's body, inhibiting its growth and eventually causing its roots to rot and cause weed death. After about 3 5 days of application, the weed stems and leaves will produce a pesticide reaction, and the weeds will die about 20 days after spraying. Pride has a strong closed germination effect on weed seeds, which ensures the outstanding advantages of long duration of Pride kill.

It is an excellent herbicide used in non-arable land such as railways, highways, stations, and reservoir areas. It is different from traditional non-arable land herbicides such as grass irrigation and forest grass cleaning, the above two herbicides are single-component herbicide products with "methylsulfuron" as the ingredient.

The Pyrox is a new ternary compound formula herbicide for areas with serious resistance (to metsulfuron), which is a generation of compound formula herbicides that solves the problem of resistant weeds.

In addition, according to the environmental characteristics of "arid compaction, saline-alkaline and sandy soil" at the highway weeding site, the concentrated suspension dosage form of adsorbent, penetrant and spreader and other additives has been increased, because Aosha has the outstanding advantages of long-term weeding and strong adsorption with soil, so it has greatly improved the safety of use on the basis of ensuring the weeding effect.

It is an excellent herbicide for weeding in non-arable land such as railways, highways, stations, and reservoir areas.

Herbicides are divided into agricultural herbicides and industrial herbicides, not to say which one is the most powerful, but to solve the problem in a targeted manner. First of all, agricultural herbicides need to remove weeds while not affecting the plants in the field, different herbicides target different plants, there are broad-leaved weeds, there are grasses weeds, which is powerful depends on what weeds you want to kill? What are crops?

Choose the ones that can kill the weeds to be killed and are harmless to the crops. It should be used after detailed consultation with a pesticide unit or agricultural material store.

Secondly, industrial herbicides should use herbicides, because industrial occasions need to completely kill the plants that are in the way, and the herbicides that need to be weeded are strong, can be weededs, and can not grow new grass for a long time, and do not need to spray herbicides frequently, so as to have a large-scale weeding, economic and labor-saving effect. The most widely used herbicide in the field of industrial herbicides is the railway sector, and the dosage is very large, and a herbicide called "arrogance" has been used on the railway for a long time, which is said to be the most effective.

In short, you can't simply say which herbicide is the most powerful, you should judge it according to specific occasions and needs, and don't just listen to the words of a business, learn some basic knowledge of weeding, and then consult the opinions of real users in related fields, understand more, compare more, and make objective evaluations and choices.

Some say that the most powerful herbicide at the moment is glyphosate. Of course, the weeding effect of glyphosate is undoubted, but glyphosate itself also has great shortcomings, such as shallow root crops can not be used, continuous use causes large residues in the soil, and some weeds are not effective (small flying peng, reed grass, cow tendon grass and duck toe grass, etc.), crop inter-row treatment is easy to produce pesticide damage, etc.

Glufosinate-ammonium and diquat are the two most promising alternatives to paraquat, but they have not been able to form the breadth of use of paraquat because of their lack of extensive and high herbicidal spectrum.

Therefore, in the post-paraquat era, it is unrealistic to simply expect any product to easily deal with weed hazards (including paraquat, which also has the short-term effect of weeding), and farmers should choose a reasonable mix when choosing herbicides, so as to achieve a cost-effective use of weeding.

<> common herbicidal pesticides are: acetochlor, alachlor, butachlor, butachlor, metolachlor, promechlor, pendimethalin, baicao, quinoxalin, 2methyl4chloro, imidazole ethylnicotin, sulfafen, isoxafen, chlorachlor, etc.

Herbicide is a pesticide, which is an agricultural agent used to kill weeds and harmful plants, weeding will not affect the normal growth of crops at the same time, mainly divided into soil treatment agent, contact herbicide, conductive herbicide, stem and leaf treatment agent, stem and leaf and soil treatment agent and other five kinds, different varieties of use of different methods, according to different weeds to choose the right agent.

Herbicide is a pesticide, which is an agricultural agent used to kill weeds and harmful plants, weeding will not affect the normal growth of crops at the same time, the main role is to reduce the nutrient consumption in the soil in addition to controlling weeds in the field, but also to kill bushes other than cultivated land.

There are many varieties of herbicides, which are mainly divided into soil treatment agents, contact herbicides, conductive herbicides, stem and leaf treatment agents, stem and leaf and soil treatment agents, etc., and the use of different varieties is different, which can be used before sowing crops and can also be used during crop growth.

When using herbicides, choose the appropriate agent according to different weeds to ensure the safety of the crop, dilute the agent with water, control the amount and concentration, load it into a sprayer to spray the weeds, try to avoid the stems and leaves of the crop standing on the agent, and the field can be mixed with a variety of weeds.

The main influencing factors before the use of herbicides are related to the growth period and environmental temperature of weeds, it is best to use the best before the weeds are unearthed or just germinate, the weeds have a certain resistance to the herbicide after the complete emergence, the effect of the herbicide is poor, and the best use temperature of the herbicide is between 20-35 degrees, and the effect of the herbicide will be reduced when it is too high or too low.
