There are dozens to dozens of herbicides in the golden autumn wind and sand ridge.
-
(1) Classification according to the method of herbicide use.
Stem and leaf treatment agent.
It is to spray herbicides on weed leaves or whole plants, such as glyphosate, paraquat, steady killing, and napping. These herbicides can be used in non-arable land as well as during the growing period of crops.
Soil treatment agents.
This type of herbicide is sprayed on the soil surface, sealing the soil and forming a liquid layer, which is inhibited or killed when the germinated seeds, seedlings, and young roots come into contact with or absorb the herbicide, such as flulenin, lasso, acetochlor, etc.
Stems and leaves and soil treatment agent.
This kind of herbicide can be used as both soil treatment agent and stem and leaf treatment agent, such as herbicide ether, atrazine, ligulon, etc.
2) Classification according to the mode of action of herbicides.
Contact herbicides.
This kind of herbicide only has a local killing effect, the plant is partially affected by contact, and the untouched part is not affected, and the agent cannot be conducted in the body. Such as herbicide ether and sodium pentachlorophenol.
Systemic conductive herbicides.
This kind of herbicide can be absorbed by plants, through roots, stems, leaves, buds, sheaths and other parts of the absorption in the body, herbicides through roots, shoots, etc., along the transpiration flow to the aboveground part of the conduction, some herbicides are absorbed by the stems and leaves along the sieve tube and photosynthesis products together with the underground part, such as triazine, substituted urea herbicides.
3) Classification according to herbicide use.
Selective herbicides.
This kind of herbicide has different selectivity between weeds and crops under certain conditions and dosages, that is, to protect crops and eliminate weeds, and most organic herbicides are selective, such as dilometre, weeding, durium, etc.
Herbicides.
This type of herbicide is not selective for weeds and crops, and can both kill weeds and harm crops, and most inorganic herbicides are biocidal herbicides.
Selectivity and non-selectivity are relative, not absolute, and can vary under certain conditions. If the dosage is increased or the method of use is changed, the selectivity can become extinction.
4) Classification according to herbicide**.
Inorganic herbicides.
Mainly in natural minerals, such as sodium arsenite, mineral oil emulsion. These herbicides are used in large quantities and have poor selectivity, and are rarely used at present.
Synthetic organic herbicides.
This kind of herbicide is currently the most varied, the largest amount of use, the widest range of applications, is the best weeding effect, the fastest development of a class of herbicides.
Microbial herbicides.
This is a class of herbicides made from living microorganisms or metabolites, such as Lubao No. 1.
Plant-based herbicides.
This kind of herbicide is the use of plant body leachate or metabolites to control or inhibit the growth of other weeds, some are called xenogram biomass, such as cinnamic acid derivatives coumarin, phenolic acid, etc.
5) Classification by chemical structure.
According to the classification of chemical structure, it mainly refers to organic synthetic herbicides, with incomplete statistics There are nearly 20 categories, including amides, anilines, substituted ureas, phenoxy, benzoic acid, carbamates, diphenyl ethers, triazine benzenes, organophosphorus, heterocyclic groups, etc.

It is used under the betel nut tree.
Camellia oleifera herbicide.
According to forest herbicides, garden herbicides, orchard herbicides, dryland herbicides - weedin.
25kg drum.
500mlx24 bottles. 50 yuan bottle.
1 bottle with mu) green environmental protection and pollution-free.
When you see green, you kill the effect quickly.
environmental remediation agents).
Dryland special) 1: Product features: This agent is a systemic conductive broad-spectrum herbicide, which can be absorbed by plant stems and leaves in the body and transported to the underground part.
The pesticide is absorbed by the foliage, and the pesticide is not sprayed on the leaf surface of the crop seedlings and does not hurt the crop tree seedlings. Spraying on the trunk and roots of crops does not hurt the crop. Spraying on tree trunks or irrigating roots has no effect. Kill that pena. After the agent is put into the soil, it decomposes quickly and has no residue.
Crops can be planted the day after tomorrow, but it is best to wait for the weeds to die. It has strong destructive power on the underground tissues of perennial deep-rooted weeds, and achieves the effect of "cutting weeds and roots".
2. Applicable objects: non-arable land weeding, such as;
Gardens. Orchard. Tea Field.
Pollution-free farm. Pharmacy. Bamboo forest.
Dry land. Mountains and forests are cultivated. Camellia oleifera forest.
Press the woods. Forestry fire line. Water conservancy embankment.
Along the railway road. Aerodrome. Power line.
Warehouse. Oil pipelines. Military facilities.
Cemetery. Tourist attractions. Ancient buildings and much more.
Three: control objects: annual and perennial grasses, sedges, broad-leaved weeds. Miscellaneous shrubs.
Miscellaneous bamboo. Reed. The nemesis of thatch, ferns, vines, etc., can completely eradicate the roots.
Four: Dosage and method of use:
500ml of medicine per mu of dryland, 75kg of grass mixed with 5 buckets of water
Medium grass to 4 buckets of water 60kg
Rice or more weeds and weeds are mixed with 3 buckets of water 45kg. The weeds stop growing after spraying. The temperature is high on the same day.
The temperature is low for 2-3 days.
Normal temperature: 3-15 days, withered yellow, deciduous leaves, and died. Root rot begins in 15-30 days.
Add a protective cover to the sprinkler head, press the sprinkler head, and spray evenly from the head of the grass to the whole foliage. Light can accelerate the weeding effect, low temperature cloudy days or shade will delay the weeding effect, but do not affect the efficacy, 1 hour after the application of rain does not affect the efficacy.
Directional spraying, the spray should be meticulous and thoughtful, so that there is no respraying and no leakage.
Precautions: This preparation should be killed when it is green, it is advisable to dilute the liquid with clean water, pay attention to avoid spraying on the leaves of other crops during the application process, and prohibit the application of pesticides in windy weather.
1.This preparation should be stored in a dry, cool, ventilated and rain-sheltered place, and it is strictly forbidden to be exposed to the sun and away from fire or heat sources.
2.The color of this preparation becomes lighter during storage, which is normal and does not affect the herbicidal efficacy.
3.This preparation should be avoided from children touching and ingesting by mistake. In case of contact**, eyes should be rinsed with water in time.

1. Tur (turvalamine, metolachlor) is a selective pre-bud dryland soil treatment agent. The agent is mainly absorbed by young shoots, inhibiting the growth of young shoots and young roots, and sensitive weeds are poisoned and killed before or just after they are unearthed after germination. It can be used for poplars, and has a good control effect on annual grasses such as barnyard grass, horsetail, cow tendon grass, goldenrod, dogtail grass and broad-leaved weeds such as shepherd's cabbage, chickweed, quinoa, amaranth.
Before poplar cuttings or before seedlings after cuttings, spray 100 ml of 72 dol emulsifiable concentrate per mu and spray 50 kg of water. This agent requires a certain amount of soil moisture to exert its effect. 2. Acetochlor is a selective pre-bud dryland soil treatment agent.
The agent is mainly absorbed by the buds of weeds, inhibits protein synthesis, makes the buds and roots stop growing, and the weeds are killed before or soon after excavation, and can be used in poplar nurseries. It has a good control effect on annual grass weeds such as barnyard grass, horsetail grass, dogtail grass, cow tendon grass and broad-leaved grasses such as chickweed and pig calypse. Before the emergence of poplar cuttings after insertion, 100 ml of 50 acetochlor emulsifiable concentrate per mu was used to spray 50 kg of water.
This medicine is not effective against unearthed weeds, and weeds should be removed before use. High temperature and humidity or rainwater after the medicine is not suitable for use, which can lead to pesticide damage caused by contact with the agent.

Herbicide refers to a type of substance that can completely or selectively kill weeds, also known as herbicides, to eliminate or inhibit plant growth.
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.
The commonly used varieties are organic compounds, which can be widely used to control weeds, shrubs, trees and other harmful plants in farmland, orchards, flower nurseries, grasslands and non-arable land, railway lines, rivers, reservoirs, warehouses and other places.

Nicosulfuron is used more often, and it belongs to the spray type of 3 to 6 leaves after seedlings. The general cost ranges from 70 to 100 yuan. Nicosulfuron + rustatrazine + two or four drops of butyrine are needed. There is also a mixture of nicotine rust dejin. It is also sprayed after seedlings, and the effect is good.
-
Herbicides are varied, what kind of grass do you want to remove, wheat herbicides and soybeans, cotton, corn is different, each has its own herbicide, herbicides are harmful items, must be used carefully, when buying, be sure to ask the seller clearly, in case of improper use, resulting in crop damage or reduced yield.

Hello friends, Camellia oleifera and mustard greens are both broad-leaved plants, and so far there is no selective herbicide on the market that can treat these two plants differently. If you want to keep the rape and kill the mustard greens, you have to pull them out manually.
Hope it helps.

According to the mode of action of herbicides, they can be divided into systemic herbicides and contact herbicides.
1. Systemic herbicides.
Some herbicides can be absorbed by weed rhizomes and leaves separately or at the same time, transported to all parts of the plant body through the conduction tissue, destroying its internal structure and physiological balance, thereby causing plant residue death, this way is called systemic herbicide, herbicides with this characteristic are called systemic herbicides, such as 2methyl4chloride, glyphosate can be absorbed by the stems and leaves of plants, and then move to all parts of the plant, including underground rhizomes, so glyphosate can prevent annual weeds, but also effectively control perennial weeds.
2. Contact herbicides.
Some herbicides are sprayed on plants, which can only kill the part of the plant tissue that is in direct contact with the agent, but cannot be internally conducted. This type of herbicide can only kill the aboveground part of the weed, and has a poor effect on the underground part of the weed or perennial weeds with underground reproductive organs, such as herbicidal ether, sodium pentachlorophenol, etc.
According to the nature of herbicides, they can be divided into biocidal herbicides and selective herbicides.
1. Biocidal herbicides.
Certain herbicides that kill a variety of weeds and crops indiscriminately, such herbicides are called biocidal herbicides, such as sodium pentachlorophenol, gram trace, glyphosate, etc.
2. Selective herbicides.
Some herbicides can kill some weeds, but not others, safe for some crops, but harmful to others, this is called selectivity, herbicides with this characteristic are called selective herbicides. For example, 2methyl 4 chloride can only kill weeds such as duck tongue grass, amaranth, heteromorphic sedge, water sedge, etc., but is ineffective against grass weeds such as barnyard grass and double-spike paspalum, which is safe for rice and suitable for use in paddy fields, wheat fields and corn fields, but has serious pesticide damage to broad-leaved crops such as cotton, soybeans and vegetables. For example, the barnyard can kill the barnyard grass and is safe for rice; Simazine can kill a variety of annual weeds such as horsetail and quinoa and is safe for corn; There are also grass spirits, wild swallows can kill wild oats and are safe for wheat, etc.
According to the herbicide application object, it can be divided into soil treatment agent and stem and leaf treatment agent.
1. Soil treatment agent: that is, spraying herbicide on the surface layer of the soil or mixing herbicide into the soil at a certain depth through soil mixing operation to establish a herbicide closed layer to kill germinating weeds. In addition to using physiological and biochemical selectivity to eliminate weeds, herbicide soil treatment uses time difference or site difference to selectively kill weeds in many cases.
Such as fluorinate, herbicidal ether, simazine, austa and so on.
2. Stem and leaf treatment agent: that is, the herbicide is diluted in a certain amount of water or other inert filler, and the weed seedlings are sprayed, and the weeds are eliminated by absorbing and conducting weeds. The stem and leaf treatment mainly uses the physiological and biochemical selectivity of herbicides to achieve the purpose of weeding and seedling protection.

Before planting, you can use a closed herbicide to control the weeds, and after 20 days, you can plant. If it has been planted, you can choose a herbicide that kills the crop, and be careful not to touch the crop when beating.
-
Paraquat is no longer available, and now only a single dose remains, glyphosate, glucophos, diquat fast, these three species are still relatively good. And it depends on you, what to fight, and what to plant afterward.
-
It mainly depends on where you use it and what kind of weeds you have. Paraquat is about to be withdrawn from the market, and glyphosate is slow to kill weeds and can be eradicated, although some malignant weeds are still not very effective, and many people report that they are a little damaged when used in orchards and nurseries. I mainly use glufosinate-ammonium now, the grass killing speed is good, the effect on malignant weeds can also be used, and it is environmentally friendly, no residue, but the cost is high, it can be regarded as paying for the ecology!
If you choose glufosinate-ammonium, it is recommended to use 30% or more content, and more than 10% is made of glufosinate-ammonium production waste liquid or so-called mother liquor, which costs money and may still have environmental hazards!
Fish ponds that have been sprayed with herbicides can be used to raise fish. >>>More
Herbicides include herbicides such as field supplement, fluoralin, oxazifen and Nayujing and other gramineous weed stem and leaf treatment agents. >>>More
Rescue methods for herbicide poisoning:
