What are the harmful effects of rice herbicide to the human body?

Rice herbicide is a class of pesticides, pesticides are a special kind of chemicals, although it can temporarily prevent and control agricultural and forestry pests and diseases, but will cause far-reaching and tragic harm to people and animals. Therefore, the use of pesticides has not benefited mankind, but human beings themselves and other living beings have brought serious disasters. According to the literature, the utilization rate of pesticides is generally 10% and about 90% of the residues are in the environment, causing pollution to the environment.

A large number of lost pesticides volatilize into the air, flow into the water body, settle and accumulate in the soil, seriously pollute the products of agriculture, livestock, fishery and fruits, and transfer to the human body through the enrichment of the food chain, causing harm to the human body. Pesticides can indirectly cause harm to the human body. The indirect way is that pesticides pollute the environment, gradually accumulate through the food chain, and finally enter the human body, causing chronic poisoning.

Highly effective and highly toxic pesticides are highly toxic and remain in the environment for a long time, and when humans and animals eat food containing residual pesticides, it will cause cumulative poisoning. Such hazards often accumulate over a long period of time before they show symptoms and are not recognized. It is through the enrichment of the food chain, and finally enters the human body, which is not easy to find in time, so it is generally not valued by people.

Moreover, this kind of pollution is wide-ranging, harms many people, and in many cases, it is the human beings themselves who poison themselves. Therefore, this kind of harm is more dangerous.

There is no harm for the time being, but if you accumulate too much, there will be problems, especially carcinogenic, because the lag effect of many pesticides has not been thoroughly studied.

Accumulation causes a burden on the liver and causes lesions. Causes cancer.

Glyphosate was sprayed in the fields.

Rice has no effect on people.

Glyphosate, generally referred to as glyphosate-ammonium salt.

Glyphosate ammonium salt, which is widely used in agriculture, has strong systemic conductivity, can be conducted to the underground part through the stems and leaves, and has strong destructive power to the underground tissues of perennial deep-rooted weeds, and can reach a depth that cannot be reached by general agricultural machinery.

The principle of action of glyphosate ammonium salt.

It is by inhibiting propenol acetone in the plant body.

shikikin phosphate synthetase, thereby inhibiting shikigenin to phenylalanine.

The conversion of tyrosine and tryptophan interferes with the synthesis of proteins and causes the plant to die. After glyphosate is put into the soil, it is inactive by combining with iron and aluminum ions, and has no adverse effect on seeds and microorganisms in the soil.

Precautions for the use of glyphosate ammonium salt.

1.Glyphosate ammonium salt is a biocidal herbicide, and the crop should not be polluted when applying the pesticide to avoid pesticide damage.

2.against perennial malignant weeds, such as white grass, fragrant aconite.

etc., apply the drug again 1 month after the first medication to achieve the ideal prevention and treatment effect.

3.Add an appropriate amount of diesel fuel or laundry detergent to the solution.

It can improve the efficacy of the drug.

4.On sunny days, the effect of medication is good when the temperature is high, and it should be sprayed in case of rain within 4 to 6 hours after spraying.

5.Glyphosate is acidic, so plastic containers should be used for storage and use.

6.Spraying equipment should be cleaned repeatedly.

7.When the packaging is damaged, it may return to moisture and agglomerate under high humidity, and crystals will precipitate during low temperature storage.

8.It is a systemic conductive herbicide, and attention should be paid to prevent the pesticide mist from drifting to non-target plants and causing pesticide damage.

9.It is easy to complex with calcium, magnesium, aluminum and other ions to lose its activity, and clean soft water should be used when diluting pesticides, and it will reduce the efficacy when mixed with muddy water or dirty water.

10.Do not mow, graze and plough the ground for 3 days after application.

Glyphosate will decompose quickly when it comes into contact with the soil, and will not be absorbed by rice, so there is no harm.

What are the dangers of glyphosate to farmland plants? Glyphosate is a kind of stem and leaf absorption systemic conduction herbicide, which is absorbed and conducted to the roots through stem and leaf absorption, so that the root system decays and dies, and is mainly used to control weeds in non-arable land in wasteland, railways, hospitals, factories and other places. It can also be used for weeding between the rows of trees, and when applying pesticides, it is necessary to choose a warm and sunny day with no wind and no rain, so as not to cause drift pesticide damage and infiltrate into the roots of trees to cause pesticide damage.

Therefore, glyphosate has certain harm to farmland plants.

How to say this, if you spray glyphosate, it will definitely go to the outside of this rice and hurt a little, but if this rice is not ripe, it will definitely have to grow for a while, and then this glyphosate will be diluted by rain, or the water absorbed by its roots, relatively speaking, it will not retain a lot in the rice.

For the question of which herbicide is not harmful to the human body, I need to use the answer template provided.

Answer: At present, most of the herbicides on the noodles will be harmful to the human body, so you need to pay attention when using herbicides. However, some all-natural plant enzyme herbicides are relatively safe, such as Zhaoshan's plant-enzyme-based sugarcane herbicides.

The main components of this herbicide are plant enzymes and microorganisms, which are natural and pollution-free, and will not cause harm to the human body and the environment. Moreover, this herbicide is biodegradable and does not pollute soil and water sources.

It is important to note that although this herbicide is not harmful to humans, it also needs to be used correctly and take care of safety when using it. For example, it is necessary to use the dosage according to the instructions to avoid residues caused by excessive use; When using, you need to wear protective equipment to prevent accidents such as contact with ** or accidental ingestion.

The use of herbicides is more important for agricultural production, but it is necessary to pay attention to the selection of suitable herbicides, follow the correct use methods and pay attention to safety, so as to ensure the safety of human health and ecological environment.

Rice is an important food crop, and the use of herbicides can effectively control weeds and increase rice yields. However, herbicides have certain potential hazards to human health, so the following points need to be paid attention to when choosing herbicides:

1.Choose a low-toxicity, low-residue herbicide: Before using herbicides, it is necessary to understand the toxicity and residues of various herbicides, and choose herbicides with low toxicity and low jujube sharp front residues as much as possible.

2.Comply with the use regulations: When using herbicides, it is necessary to strictly abide by the use regulations, use them in accordance with the instructions for use, and do not overuse or abuse them to avoid harm to the environment and human health.

3.Pay attention to safety protection: When using herbicides, it is necessary to take necessary safety protection measures, such as wearing masks, gloves, protective clothing, etc., to avoid contact with herbicides and causing harm to the human body.

4.Safety interval: After the use of herbicides, it is necessary to leave enough safety intervals for the herbicides to decompose in the rice and avoid the harm caused by residues to human health.

In short, the harm of herbicides to human health can be reduced by choosing herbicides with low toxicity and low residues, strictly abiding by the regulations for use, taking necessary safety precautions, and leaving sufficient safety intervals. It is advisable to consult a professional or pesticide dealer before using herbicides to understand the relevant information and how to use the stool.

Glufosinate beats rice, and the seedlings will die.

Glufosinate is suitable for weeding in orchards, vineyards, non-arable land, and can also be used in potato fields to facilitate harvesting.

Control objects annual and perennial dicot and gramineous weeds, such as sagetail, horsetail, barnyard barley, barley, multiflora ryegrass, dogtail grass, golden dogtail grass, wild wheat, wild corn, perennial grasses and sedges, such as duck grass, mango grass, fescue, fluffy grass, rye grass, double slag spike paspalum, reed, early maturing grass. As well as wild oats, finch wheat, spicy grass, pig caesthetic, baogai grass, small wild sesame, nightshade, chickweed, field forget-me-not grass and creeping ice grass, stolon, whisk grass, moss, dogtooth root, amaranth retroflexus, etc.

Mode of action A non-selective herbicide with partial systemic effect, mainly used as a contact killer when used. After application, the active ingredient acts through the leaves, and the seedlings that have not yet been unearthed will not be harmed.

Mechanism of action It is a phosphonic acid herbicide and an inhibitor of glutamine synthesis. In a short period of time after application, the ammonium metabolism in the plant is disordered, and the cytotoxic ammonium ions accumulate in the plant, and at the same time, photosynthesis is seriously inhibited.

How to use The requirements for the application time are not strict, and the general application amount is 5 to 6 liters of water per hectare. According to different weeds, the amount of use changes, generally weeds with 3 to 5 liters, medium stubborn weeds to 10 liters of water agent per mu, anti-broad-leaved weeds should be applied at the beginning of vigorous growth, and the control of grassy weeds should be applied at the beginning of leafing, up to 20kg mu, to control the slings and ferns in forests and alpine pastures.

There are more than 100 kinds of weeds in paddy fields, which can be mainly divided into three categories: gramineous weeds (such as barnyard grass), broad-leaved weeds (such as duck tongue grass), and sedge weeds (such as heteromorphic sedge). Although China has a vast territory, many different climatic conditions, different cultivation systems and varieties, the weeds with serious damage mainly include: gramineous weeds

barnyard grass, goldenrod, double-spike paspalum, Lee's grass; Cyperaceae weeds: heteromorphic sedge, water triangular sedge, flat-stalk stalk, firefly, water chestnut, cow felt; Broad-leaved weeds: snakehead sausage, hollow lotus seed grass, duck tongue grass, water amaranth, Mo Shangcai, festival vegetables, dwarf cigu, clove knotweed, etc.

Weeds in paddy fields mainly affect and harm rice by competing with rice for water, fertilizer and light. Because weeds have the characteristics of fast growth and reproduction, developed root system, and tall weed plants, they have the advantages of competing for water, fertilizer and light in the case of symbiosis with rice, thus inhibiting the growth of rice. In addition, weed seeds mixed with rice can reduce the quality of rice.

There are two peak periods for the growth of weeds in paddy fields, the first peak of weeding generally appears 5 7 days after sowing and about 10 days after transplanting and throwing seedlings. The second peak of weeding appeared about 20 days after sowing, planting and throwing, mainly sedge weeds and broad-leaved weeds.
