What are the best ways to get rid of weeds without pesticides?

hoe with a hoe, pluck by hand, etc. Weeds can be completely removed with a hoe, and weeds can be completely removed by hand.

If you don't use pesticides, you can uproot the weeds, and after autumn, you can continuously turn the land deep to make the weeds rot and turn them into fertilizers, which can completely remove weeds.

The complete removal of weeds is as follows:1. Use a shovel, using a shovel to remove weeds is the easiest way, we use a gardening shovel to shovel the weeds little by little, although this method can shovel the weeds relatively clean, but it is more energy-consuming and time-consuming.

2. Remove the flowers and seeds, if you want to make the weeds at home less and less, you can pull out all the flowers of the weeds during the flowering period and the seed-bearing period, because once the weeds bloom, they will begin to multiply and spread. In addition, some flower friends like to use weeds for composting, which will also lead to the spread of weeds.

3. Spread plastic film, when we raise flowers in the yard, if it is the season when the plant grows more vigorously, we can spread a little plastic film on the ground, which can prevent the growth of weeds, and also has the effect of heat preservation and moisturizing.

Just pull out all these weeds. You can also cover the ground with some mulch, so that the weeds have no way to get light, and it can also effectively restrict the growth of weeds.

1. You can use baking soda and salt to eliminate weeds, and the saline substances in baking soda can remove weeds. 2. Edible vinegar, because vinegar contains sodium chloride acetate, which is the main ingredient for removing weeds.

The method of completely removing weeds is to completely pull out the weeds with tools and cover the land with some mulch, so that the weeds have no way to shine and effectively restrict the growth of weeds.

(1) Manual copy weeding. This includes hand-pulling weeds and using simple single farm tools for weeding. (2) Mechanical weeding.

Zhi uses animal power or mechanical power to pull DAO's weeding implements. (3) Physical weeding. Use physical factors such as water, light, and heat to control weeds.

For example, the fire method is used to reclaim land and weed. (4) Chemical weeding. That is, the method of removing weeds with chemical herbicides without harming crops.

For annual weeds germinated by seeds, soil treatment agents with long effective period are generally used to control them, and selective herbicides with strong conduction are used for perennial weeds germinated by rhizomes. (5) Biological weeding. Use insects, livestock, pathogenic microorganisms and competitive replacement plants and their metabolites to control weeds.

For example, fish and ducks are raised in rice fields to control weeds. (6) Ecological weeding. Use agricultural or other measures to create an ecological environment over a large area that is conducive to the growth of crops and not conducive to the reproduction of weeds.

If the water-drought rotation system is implemented, it has a good control effect on many weeds that are not resistant to flooding or drought.

Abstract: Herbicides are generally used to control weeds. Herbicides are divided into selective herbicides and non-selective herbicides, if it is ridges, orchards, wasteland, you can use non-selective herbicides, such as glyphosate, glufosinate ammonium and paraquat, etc., if it is used as a herbicide in corn fields, wheat fields, rice fields, then use selective herbicides, such as grass, nappur, etc.

What pesticides are used to control weeds.

Herbicides are generally used to control weeds. Herbicides are divided into selective herbicides and non-selective herbicides, if it is ridges, orchards, wasteland, you can use non-selective herbicides, such as glyphosate, glufosinate ammonium and paraquat, etc., if it is used as a herbicide in corn fields, wheat fields, rice fields, then use selective herbicides, such as grass, nappur, etc.

What medicine is used to control weeds when high Dan king grass grows weeds.

It is recommended to use glyphosate, in order to expand the herbicidal spectrum, dimethyltetrachloride can also be mixed, and some laundry detergent can also be added in order to increase the spreadability of the solution. Although the effect is slower, the effect is still ***.

Not yet.

Herbicide residue damage has become the most serious problem at present, making the determination of herbicide residues in water and soil a prerequisite for the application of herbicides. Affected by soil pH, temperature and other factors, the residues cause pesticide damage to sensitive post-stubble rotation crops, even after 2-3 years of application.

Bensulfuron is a systemic and conductive sulfonylurea herbicide widely applied worldwide, which is very likely to bring potential harm to the ecological environment, grain crop yield, food safety and human living environment. Some herbicides produce pesticide damage in large-scale promotion, especially the hidden pesticide damage has a great impact on yield, resulting in the adverse consequences of weeding not increasing yield or reducing weeding yield.

Due to the changes in cultivation and tillage systems, the widespread use of herbicides, the mixing of herbicides, and genetically modified crops, the weed community changes and the enhancement of weed resistance, resulting in a significant decline in the efficacy of commonly used herbicides. According to statistics, weed pests have shown resistance to every herbicide on the market today.

Now are implementing organic agriculture, refusing herbicide weeding, green and pollution-free weeding methods, manual weeding, mechanical weeding, weeding cloth weeding, weeding cloth weeding can not only have a good inhibitory effect on weeds, but also moisturize and fertilizer.

There shouldn't be one yet, there are too many similarities in plants. There are a lot of pesticide damages, and in recent years, the pesticide damage caused by herbicides is more common in all provinces.

How to get rid of weeds, use pesticides, and what kind of pesticides are good for the land that is not planted all year round.

Hello dear, I'm glad to answer for you, I'm your exclusive ** answer teacher, thank you for your patience! To clear the land that is not planted all year round, the best effect is to use ethylammonium. There are many kinds of pesticides to remove weeds, and glyphosate, diquat and so on should be selected according to local conditions.

According to the genus of the weed, herbicides are selected, such as benzenolone, benzsulfuron, etc. The effect of gram without a trace should be done well. Note, first of all, it is suspected of imitation, and it is correctly configured according to the instructions for the use of pesticides; Secondly, when spraying pesticides, it should be carried out under windless or breezy weather conditions, and the spraying process should be divided into equal doses according to the area of the field.

Again, after spraying pesticides, they should be cleaned strictly. Low temperature is not conducive to herbicide absorption by weeds, application period: Different herbicides have different requirements for weed growth period, such as soil sealant requires pre-bud medication, and the efficacy of weeds is not good after unearthed; Post-seedling herbicides require weeds to be used at the three-to-five-leaf stage, and the grass is too old to play a bad effect, such as winter wheat producing areas, and the pesticide application time is divided into pre-winter application and post-holiday application.

Weeds are an important factor affecting plant growth, they compete with crops for fertilizer, water, and light, and some weeds are also the host of crop diseases and pests and the place of wintering.

In the face of weeds in the field, chemical weeding may be used in many places, which is relatively less labor-intensive. However, in today's world, where people pay more and more attention to environmental protection and green life, chemical weeding has also been criticized. In fact, there are advantages and disadvantages of chemical weeding, the advantage is to reduce labor intensity, and the disadvantage is that chemical herbicides have a certain impact on orchard vegetation, soil, pests and diseases.

How to prevent the growth of weeds without pesticides in the field?

Weeding can be done with a weed-proof cloth.

Weed-proof cloth is a green, healthy and environmentally friendly way of weeding, which will neither damage the ecological environment nor cause harm to the soil.

After the weeds are weeded with anti-weeds, due to the inability to see light, photosynthesis is inhibited, unable to grow, and can only wither. Water permeability and air permeability, water and fertilizer can penetrate into the soil through the ground cloth, and the air permeability is good so that the roots of crops can breathe. After the ground is covered with anti-weed cloth, due to the good air permeability of the ground cloth, it increases soil earthworms and other microorganisms, improves the soil microenvironment, promotes soil looseness, and has no compaction.

If it is weeding, then there are many treatment methods, such as manual or machine weeding, or biological herbicides to kill weeds, etc., which can play a certain role.

Otherwise, we can only plant some crops that can coexist with the crops we grow, so as to squeeze the potential growth space of weeds, so that weeds can be effectively suppressed to a certain extent. But your problem is to prevent the growth of weeds, which is much more difficult. In all my years of farming, I have only seen one way, and it is a very stable way.

But the cost is high, and there are some troubles in operation. First of all, the microorganisms required to ferment organic matter must be able to withstand high temperatures above 60 degrees Celsius.

In fact, the heat itself is provided by facultative anaerobic microorganisms. Second, you need an organic fertilizer formula that contains organic matter, nitrogen, phosphorus, potassium, and all trace elements for effective comprehensive nutrition. On top of that, microorganisms and organic fertilizers are mixed, buried in the ground, and the surface is covered with a closed mulch, thus achieving the purpose of sealing.

In this way, through two months of microbial fermentation, high temperatures can be generated, killing grass seeds in the soil and preventing weeds. This is a question and answer that I can ask as an old farmer.

I was born in the 50s of the 20th century, from a period of primitive farming and agricultural production without fertilizers and pesticides. Simple weeding can only be done with livestock plows and manual eradication of weeds, and small areas of excellent crops can be pulled out manually. Now, if herbicides are not used, in addition to the original physical weeding methods, there are also weeding methods such as black mulch.

Rice field weeding is to use large water pressure grass or manual weeding, can also wait for rice seedlings to release ducks, geese or grass carp, called ecological weeding. There are several methods of weeding in the field that do not use pesticides in the orchard, the most common being physical weeding. Weeding, weeding, manual weeding, using lawn mowers, and understory weeding can also properly breed chickens, ducks and geese and other ecological weeding; According to the actual situation, green manure plants can be planted to inhibit the growth of harmful weeds, and the way of ground cover also has an application to the black weeds in the river, and now there are chemical herbicides, which greatly improve the efficiency of agricultural production, the progress of scientific and technological civilization, and bring a lot of convenience and efficiency to human production and life at the same time.

The land needs to be treated, deep ploughing needs to be carried out in advance, and weeds need to be constantly cleaned up in daily life so that weeds can not grow.

It can be covered with plastic film, the preventive effect of plastic film is very good, the cost of this thing is relatively low, and it can also be better heat preservation.

To remove weeds from the soil regularly, turn the weeds into the ground. Anti-grass cloth can be selected.

First, the dosage should be accurate, the spraying should be uniform, and there should be no leakage or re-spraying. For example, the continuous application of herbicides containing chlorsulfuron-methyl will not only cause pesticide damage to the later crops, but also cause pesticide damage to the current crops.

The best way is to spray herbicides after the rain, you can choose to do weeding on cloudy days, spray herbicides on the ground when weeding, or make a cordon in the ground, and wash the vegetables several times when eating vegetables.

The methods of preventing herbicide residues include photolysis, volatilization, chemical decomposition, biodegradation, soil adsorption, and leaching.

It is necessary to grasp the amount of herbicide, do not use too much, dilute it appropriately, and the herbicide must be sprayed evenly when spraying, and the way of spraying must be mastered.
