How to make herbicide formulas, recipes for homemade herbicides

Homemade herbicide formula ratio:

1. Formula 1.

1) Prepare 1-2 kg of salt, 4 litres of hot water, and a small amount of liquid soap or dish soap.

2) Add salt to hot water, stir well, and then mix with soapy water or dish soap, and mix well again before it can be used as a herbicide.

3) Salt water can kill weeds, each use needs to be diluted twice to spray, spraying time to dry and hot weather at noon.

2. Formula 2.

1) Prepare 10 grams of salt, 15 liters of white vinegar, 200 ml of water, and 1 watering can.

2) Put salt into the watering can, then pour white vinegar and water, shake evenly and then use it as a herbicide.

3) The acetic acid in white vinegar can directly kill weeds, and the sodium chloride in salt can alkalize the land, so that weeds die of lack of water.

Accurately weigh the herbicide as required, add a small amount of water and stir it to fully dissolve it as the mother liquor, and add a certain amount of the mother liquor to the quantitative water to dilute it evenly.

To prepare the dilution in the sprayer, you must first add about 10 cm of water to the sprayer liquid, slowly add the agent or mother liquor, and then add water to the water line, but can not be filled, such as the sprayer medicine box is full, when the pesticide applicator is walking, the medicine in the medicine box is difficult to shake, and the agent is easy to sink or float, which affects the weeding effect.

Precautions for herbicide use

When using herbicides, it is necessary to find out the types of weeds and choose the appropriate herbicide varieties according to the types of weeds. When applying pesticides, it is necessary to control the concentration of drugs, and apply them in strict accordance with the instructions, as large doses can easily lead to drug damage. When spraying drugs, it is necessary to spray evenly and thoughtfully, if the spraying is uneven, it will not only affect the efficacy, but also be prone to pesticide damage, which will affect the growth of crops.

When applying pesticides, it should be evenly blended, and the spray should be thoughtful, not heavy and not leaking. In the growing period of crops, it is necessary to prevent the liquid medicine from splashing on sensitive crops, and avoid spraying herbicides on the green parts of plants, so as to reduce pesticide damage and improve the weeding effect.

Use white vinegar, dish soap, salt, 84 disinfectant, and empty bottles. Add 2 tablespoons of white vinegar, 1 tablespoon of salt, 1 tablespoon of 84 disinfectant, 1 tablespoon of dish soap, add 10 times the water to the bottle, ** if there are weeds, spray it, the effect is quite good, you can try how to make your own herbicide in the countryside, first you need a hoe, and then go to the place where you want to weed, use the strength of your just full meal to make the hoe move, the faster you are, the faster the weeding, so that you can achieve the purpose of weeding.

I saw a formula on the Internet, but I don't know if it's reliable? The formula used is to add about 1 2 kg of salt to 4 liters of hot water, the principle is that the effect of this formula is salty enough, because it is salty enough to remove weeds, and then add a little dish soap or soapy water, so as to prepare a two-liter bucket 2, the formula is to add 4 liters of hot water to about 1 1 2 kg of salt, and implement a taste of salty, because salty enough can remove weeds, and then add a little dish soap or soapy water to make a herbicide.

With the progress and development of science, herbicides for various crops such as herbicides for wheat fields and herbicides for cotton fields have appeared one after another, which has greatly saved labor and improved production efficiency for farmers. Herbicides are very simple to make, pour a glass of laundry detergent, pour a glass of vinegar, an appropriate amount of water, diluted, and a small cost of herbicide. It is soda ash, add water laundry detergent, it is also a herbicide, but it cannot be sprinkled on the plant, it is harmful, and the best herbicide is yourself.

Herbicides are bought, and who will make herbicides in rural areas! In the past, when there were no herbicides, they were all manually hoeed or pulled by hand, and no one knew how to make herbicides. For most farmers in rural areas, the most annoying thing should be that the weeds that grow everywhere in the field, the vitality of these weeds is very strong, how to get rid of it can not be clean, even if it is removed this year, it will still grow in the next year, and a herbicide made by itself, the risk factor is greater.

Nowadays herbicides are bought off-the-shelf. If you don't want to use herbicides, you can do it manually.

Method 1: Preparation of materials: salt, soap or dish soap, hot water.

Method: Add 4 liters of hot water to 1 2 kg of salt, stir well, add a small amount of dish soap or soapy water, and it can be made into a herbicide.

Principle: Salt water can remove weeds, each use can be diluted with water to spray, generally in the hot and dry weather at noon effect is better.

Method 2 Preparation: salt, white vinegar, water, watering can.

Method: Put 10g of salt into the watering can, then pour 15ml of white vinegar, then add 200ml of water, shake well.

Principle: Sodium chloride in table salt can alkalize the land, so that weeds die of lack of water, and the acetic acid in white vinegar can kill weeds.

You can add about 1 2 kg of salt to 4 litres of hot water, the principle is that this recipe is salty enough, because it is salty enough to get rid of weeds, and then add a little dish soap or soapy water to make a herbicide.

1.First, open the lid of the watering can, with the help of a plastic bottle, and pour disinfectant into it. 2.

Then pour in the white vinegar, the ratio of disinfectant and white vinegar is 1:1,. 3.

Then close the lid of the watering can and shake it a few times to finish. 4.Principle:

White vinegar kills weeds that are very new at the roots. The disinfectant can kill the mature old. 5.

Finally, just spray the liquid with a watering can, not the whole pot.

1. Prepare salt, soap or dish soap, hot water, add 1 2 kg of salt to 4 liters of warm water, then add a small amount of dish soap or soapy water, stir well to make herbicide.

2. Method 2: Prepare salt, white vinegar, water and watering can, put 10g of salt and 15ml of white vinegar into the watering can, then add 200ml of water, shake well to make herbicide.

You don't need to buy herbicides, you can make them yourself at home.

Homemade herbicides are less practical.

Herbicides, no way to make your own. And different weeds should be treated with different herbicides. If you encounter some home remedies, but because of the different weeding conditions, it will also cause the plants you want to breed to die. The best way to do this is to buy the corresponding herbicide.

Among the herbicides, sodium chlorate, borax, senbana arsenate and trichloroacetic acid have the effect of dead 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.

Introduction to herbicides

Herbicide refers to a type of substance that can cause weeds to die completely or selectively, also known as herbicides, to eliminate or inhibit plant growth. 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.

There are a variety of pests and natural enemies in the farmland environment, and under natural environmental conditions, they are mutually restrictive and in a relatively balanced state. The extensive use of herbicides kills a large number of natural enemies of pests, seriously destroys the ecological balance of farmland, and leads to the enhancement of pest resistance. Pests that produce resistance to pesticides in China have spread all over grain, cotton, fruit, tea and other crops.

It has seriously polluted the ecological environment and destroyed the natural ecological balance.

The above content refers to Encyclopedia - Herbicides.
