How do I clean a sprayer that has been sprayed with herbicides?

For farmers, the sprayer is an indispensable tool for spraying pesticides, herbicides, and foliar fertilizers. In the past, living conditions were poor, and there was often only one sprayer in a household. In our case, we still use the same hand-cranked sprayers as we used to be.

That is, carry it on your back, and then hold a long sprinkler head in one hand, and shake it up and down with the other hand, and spray the water in the tank by continuously pressurizing it.

Because there are more crops planted, and the pests and diseases of different crops are different, the pesticides that need to be sprayed are also different. In order to avoid drug damage, it needs to be cleaned after each use, this work is sloppy, and it is not lazy. If the sprayer has just been sprayed with herbicide, should it be cleaned so that it will not cause pesticide damage the next time the pesticide is sprayed?

The cleaning of the sprayer is actually relatively simple, because we basically use a hand-cranked sprayer, its structural components are also very simple, and it is not troublesome to clean. When the pesticide is sprayed, there will be some pesticide residue in the sprayer, and this part can be poured directly from the water inlet of the sprayer. That is, turn the sprayer upside down and pour it out of the water filler.

To be on the safe side, it is best to dump it on the wasteland and never into the water.

Then pour in some water, shake it a few times, and rinse the pesticide in the sprayer with as much water as possible. This can be repeated two or three times. In order to ensure that the pesticide in the sprayer is thoroughly cleaned, you can pour in some laundry detergent or baking soda and shake it a few times to let the laundry detergent fully dissolve in water.

Close the lid, turn off the switch on the sprayer, and grab your arm and shake it up and down like spraying a pesticide. This will flush the pesticide residue from the water pipes.

When the water in the sprayer is sprayed clean, repeat this action two or three times, and finally rinse it twice with clean water, so that the pesticide residue in the sprayer is basically cleaned. Then pour all the water in the sprayer out of the water inlet, carry it home, and place it upside down in a high place to drain the water in the sprayer. Since the sprayer is used to spray pesticides, it must be kept out of the reach of children!

Some people say that you can buy two sprayers, one for pesticides and one for herbicides, so that you don't have to clean them. In fact, no matter how many sprayers you buy, different pesticides have different properties, and it is best to clean them after use, so as to avoid pesticide damage.

As for what the subject said, because of the use of a herbicide (glyphosate) sprayer, but without cleaning, the vegetables were directly sprayed with pesticides and caused diseases, if it is solved. This seems to be a real help, because glyphosate is a biocidal herbicide, which inhibits the metabolism of amino acids by inhibiting the activity of relevant enzymes in the plant, which leads to plant death. Therefore, there is generally no salvage measure.

First of all, you must wear leather gloves, otherwise the drug is not clean on the hands and it is easy to cause problems, your own sprayer is generally to rinse several times with water, open the lid and inject water, wipe it thoroughly several times with a rag, and then wash it repeatedly with water, open the lid and dry for a while!

First of all, wear gloves when cleaning, then wash with mud water, and then clean all the mud, and you can use it again.

The sprayer can still be used after spraying the herbicide. Be sure to wash carefully, residual pesticides will have a serious impact on crops, and it is best to use them alone.

Soaking in alkaline water is an effective way to remove residual pesticide damage. After spraying herbicide, you can rinse all parts of the sprayer repeatedly with clean water, put them in the medicine bucket, fill the medicine bucket with 1% soda solution, soak for 12-24 hours, and rinse the spray rod and nozzle with alkaline water in the medicine bucket, spray it several times with alkaline water, and clean up the residual medicine in the internal pipeline. Finally, rinse with clean water before reuse.

Herbicides are selective and incidicative: selective herbicides are relatively safe for crops while selectively killing weeds; The herbicide grass seedlings are not distinguished, and crops and weeds are eliminated without choice. However, selective weeding and incidisalial weeding are relative, and with the different types of crops, growth periods, application concentrations and use methods, selective herbicides will also lose their selectivity and harm crops.

The first method: you can use the method of clean water to clean, for the commonly used herbicides in the wheat field.

After use, the barrel and other parts should be cleaned with clean water immediately, and should be cleaned many times, and then filled with water to soak the agricultural equipment for about 2 days, and then cleaned about 3 times.

The second method: You can also use baking soda, which is commonly used in life.

In fact, it has a very big role in daily life, and there are many effects, cleaning herbicides also have a great effect, you can put baking soda into water, dissolve it and call it into the sprayer for cleaning, repeat the cleaning several times, the effect is also very good.

If you want to clean a sprayer that has been sprayed with herbicides, don't just wash it by hand. The herbicides sprayed will have some harmful substances in them, which are likely to cause serious harm to the human body. If you touch it with your hands, it may ulcerate.

You can choose to wash it with clean water 2 or 3 times, and then soak the bucket in clean water. Soak for 24 hours and rinse a few times before you can continue to use it. If there are some corners inside that cannot be cleaned, you can also choose to use a small stick and tie a rag to clean it.

The cultivation season is constantly starting, so the only option is to remove the weeds in the field. You can see farmers wrapping themselves tightly in the fields of the countryside, spraying herbicides not far away. The purpose of this is to kill the weeds and then plant the seeds in them.

The voltaic sprayer will spray a large amount of foliar sprays, which can gradually wither the grass from the surface. In the process of spraying, if you don't do a good job of self-protection, it is very likely that you will also be injured by these things. <>

Some herbicides are of different types, so you must add a small amount of laundry detergent to shake well. Put the nozzle nozzle into the medicine barrel and shake it thoroughly. Laundry detergent has a good resistance effect, so you don't have to worry about not cleaning it clean.

Most herbicides are acidic, and if they are not cleaned, they may affect the effectiveness of the next application. After spraying, you should wash it immediately, and if you want to make a washing powder, it is best to have a rich lather. <>

In general, timely weeding should be carried out during the growth period of wheat, so as not to affect the yield in the later stage. There should be two liters of sprayers in the home for use separately, so that different kinds of things can be mixed with different kinds. If you find an odor in the sprayer, it means that the previous bucket has not been cleaned.

Do not continue to use these barrels, there is a high chance that you will harm the crops in the field.

You can use dish soap water or soapy water blister sprayers; No, it's easy to get poisoned.

You can add some muddy slurry to the sprayer, or add water mixed with baking soda for cleaning, and rinse it with water again; The sprayer cannot be washed directly with the hand, and there will be a risk of poisoning.

You can choose to wash it off with dish soap. I don't think so, because sprayers can be corrosive.

Many farmers have done something wrong about this matter, which leads to regret, that is, the sprayer that has been sprayed with herbicides like the subject is not cleaned and used to fight the vegetable insecticide in their own vegetable garden, and the vegetables are damaged.

So, I would like to share with you my personal experience how to clean a sprayer that has been sprayed with herbicides. As we all know, herbicides are generally more acidic, and acidic herbicides are best rinsed with soda, which is what our farmers often call "baking soda", commonly known as alkaline water.

Proper rinsing method:

After the herbicide, fill the watering can with water, add about 60 grams of baking soda noodles from the water, it is best to let it melt completely, and soak overnight; Then, the next day, turn on the sprayer switch and let the sprinkler head rinse with alkaline water just like we do with herbicides.

But I see that the subject said in the problem description that he had played a sprayer of glyphosate, and the important thing is that this drug is more domineering and difficult to wash off; Then I personally recommend rinsing it with alkaline water, and then washing it several times with the ash on the bottom of the pot in our rural stove pit, so that the residual glyphosate agent in the sprayer is clean and free of residue.

Notes:Agricultural planting is very hard, and farmers can almost use sprayers to grow crops, but there is too much farm work when the farm is busy, and there is no leisure time to put down the rake and broom; After the sprayer is finished, the herbicide may be placed there, to do other work, think that there is time to clean it, and then forget to take it and use it directly, I have experienced this situation myself, therefore, it is especially necessary to pay attention to this, and we must clean the sprayer in time to avoid unnecessary losses caused by busyness.

Summary:Personally, I suggest that we farmers should prepare two sprayers, one professional for herbicides, and the other for insecticides. I think that rural farmers are more careful, I don't want to buy two, I am reluctant to buy two, I think it is too wasteful, then use a sprayer, just follow the flushing method I mentioned above to ensure safety.

How to clean a herbicide sprayer depends on the type of herbicide. In the case of glyphosate, you can first wash the sprayer with cloudy muddy water, and then rinse the mud with clean water. ;If it is an acidic herbicide, you can put some alkaline substance in the sprayer, such as edible alkali, and pour in the appropriate amount of water to clean.

Most pesticides are acidic. You can use the principle of acid-base neutralization, put some alkaline things (such as some edible alkali or baking soda), shake it up and down, and wash off the pesticide residues in the sprayer. However, if a special herbicide such as paraquat (currently banned) or glyphosate is used, it can be cleaned with laundry detergent.

A sprayer that has been sprayed with herbicide (glyphosate) can be rinsed once with turbid water and then rinsed with clean water to remove the mud.

At present, there are three types of herbicides on the market: water, suspension and emulsion. Therefore, it is necessary to decide how to clean the most correctly according to the type you use, but the principle is actually the same. The detergent washes off the pesticide residue in the sprayer by shaking it up and down.

Take care to protect yourself, the drug has a corrosive effect.

Sprayers that have been sprayed with a fucinomazine herbicide can be cleaned with soapy water or dish soap.

Nicotinopethazine is a mixed preparation of nicosulfuron and atrazine, which can effectively control annual grasses and broad-leaved weeds in corn fields, such as: barnyard grass, dogtail grass, horsetail, cow tendon grass, Kanmai Niang, purslane, Amaranth retroflexus, quinoa, knotweed, amaranth, iron amaranth, etc.

Precautions: 1. Use up to 1 time per season of crops. Before preparing the liquid medicine, shake the bottle well, stir it fully before use, and do not repeat the application in order to avoid pesticide damage.

2. Do not mix with organophosphorus insecticides, and do not use organophosphorus insecticides within 7 days before and after the use of this agent, so as to avoid pesticide damage.

3. It should not be mixed with alkaline pesticides, and should not be mixed with fertilizers, jujube seeds, etc., to prevent cross-contamination.

4.After a few days of application, the crop sometimes fades or inhibits growth, but this does not affect the effect and there is no need to respray. Sweet corn, waxy corn, burst corn and seed corn should not use this product.

5. Soil cultivation within one week after application will affect the weeding effect. Rain after application will affect the weeding effect, but if it rains 6 hours after application, it will not affect the effect and there is no need to respray. In case of special conditions, such as high temperature and drought, low temperature, and weak corn growth, please use with caution.

6. If too long residual herbicides are used in the wheat field, such as metsulfuron-methyl, chlorsulfuron-methyl, etc., and the corn field where the broad-leaved crops are intercropped, this agent should not be used.

7. Use this agent in strict accordance with the label content and technical information, and use this product for the first time under the guidance of the local plant protection department.

8. Wear long clothes and trousers, gloves, eyes, etc., and do not eat, drink, smoke, etc. Wash your hands and face after application.

9. After the application utensils are used, fully wash the medicine barrels, nozzles, pipes, etc., to avoid pesticide damage; Waste water from cleaning utensils should not be discharged into rivers, ponds, and other water sources, and waste should be properly disposed of.

10. Avoid affecting the surrounding bee colonies during the late pesticide application, prohibit the flowering period of nectar source crops, silkworm room, and mulberry garden, stay away from the aquaculture area, and prohibit cleaning pesticide application equipment in water bodies such as rivers and ponds.
