Botanicals are just a description of what they're made from**.
For example, matrine is a plant extract that can be used to kill insects, and some pesticide companies have developed it to be sold as a preparation. Then the size of the package is according to the medication habits of local farmers.
For example, with knapsack sprayers, you can process 10ml, 50ml, 100ml ......and so on.
If it is used for orchards, it may be a large bucket of 300 catties of water and a tractor-driven spray, which is suitable for processing into 1L or even 25L barrels.
For example, pyrethroid, originally a plant extract, but in the 70s of the last century, its analogues can already be synthesized, and now all pyrethroid insecticides are compounds derived from natural pyrethrins. It has also been widely used in production, and the packaging specifications range from 10ml to 200L.
Therefore, the botanical preparation only states its **, if Huoxiang Zhengqi liquid is also considered a botanical preparation, then the botanical preparation can also be traditional Chinese medicine, poison (curaretoxin), spice (lavender), chemical raw materials (saponaria), industrial raw materials (castor oil). However, there are still few types of plant-derived pesticide formulations in the current production and application.
As for whether the package is small, it can be processed and made according to the actual needs in production.
Hope mine is helpful to you!

Belongs, why don't you belong, it must belong, how can you think that you don't belong! Botanical preparations just show that this kind of thing is made of plants, and it is used in many ways, as long as it is toxic, it doesn't matter, whether it is a pesticide or something!

<> herbicide is a pesticide, which refers to an agent that can kill weeds or harmful plants, and is often used in agriculture to control weeds in farmland and kill weeds and shrubs in non-arable land. Commonly used herbicides include selective herbicides, biocidal herbicides, selective herbicides include prometrinet, fluoralin, gacaocanol and other drugs, such drugs can control weeds and will not cause harm to crops, biocidal herbicides include paraquat, glyphosate, such drugs are toxic to weeds and crops, as long as the liquid contact with the green part of the plant can kill it.
1. Are herbicides pesticides?
1. Herbicides are not pesticides.
Herbicides are pesticides, which refer to agents that can kill weeds or harmful plants (but do not affect the normal growth of crops), and are usually used in agriculture to control weeds in farmland and kill weeds and shrubs in non-arable land.
2. Commonly used herbicides.
1) Selective herbicides.
Including drugs such as Gaicaonen, Simazine, Gol, Prometrigin, and Flulelin, which can kill weeds and will not cause harm to crops (different crops have different resistance to such herbicides).
In agricultural production, most of these herbicides are used to control weeds, whether it is monocotyledonous weeds or dicoted weeds.
2) Biocidal herbicides.
Drugs such as paraquat and glyphosate are toxic to all plants, whether weeds or crops, and are killed when the green parts come into contact with the solution.
This type of drug is mainly used before sowing, before emergence after sowing, on the main and auxiliary roads of nurseries, and can also be used for weeding on roads, railways, forest fire roads, warehouses, and non-arable land.
2. What are the types of herbicides?
1. Contact herbicides.
These include drugs such as paraquat, herbicides, diphenyl ether herbicides, etc.
2. Systemic conductive herbicides.
Including promechlor, glyphosate, glyphosate and other drugs.
3. Stem and leaf treatment agent.
Including drugs such as Napjan, paraquat, Gacaonol, glyphosate, and Wende.
4. Soil treatment agent.
Including acetochlor, fluleline, lasso, simazine and other drugs.
5. Stems, leaves, soil treatment agents.
Including atrazine, herbicide, atrazine and other drugs.

Herbicide is a pesticide, which is an agricultural agent used to kill weeds and harmful plants, weeding will not affect the normal growth of crops at the same time, mainly divided into soil treatment agent, contact herbicide, conductive herbicide, stem and leaf treatment agent, stem and leaf and soil treatment agent and other five kinds, different varieties of use of different methods, according to different weeds to choose the right agent.
Herbicide is a pesticide, which is an agricultural agent used to kill weeds and harmful plants, weeding will not affect the normal growth of crops at the same time, the main role is to reduce the nutrient consumption in the soil in addition to controlling weeds in the field, but also to kill bushes other than cultivated land.
There are many varieties of herbicides, which are mainly divided into soil treatment agents, contact herbicides, conductive herbicides, stem and leaf treatment agents, stem and leaf and soil treatment agents, etc., and the use of different varieties is different, which can be used before sowing crops and can also be used during crop growth.
When using herbicides, choose the appropriate agent according to different weeds to ensure the safety of the crop, dilute the agent with water, control the amount and concentration, load it into a sprayer to spray the weeds, try to avoid the stems and leaves of the crop standing on the agent, and the field can be mixed with a variety of weeds.
The main influencing factors before the use of herbicides are related to the growth period and environmental temperature of weeds, it is best to use the best before the weeds are unearthed or just germinate, the weeds have a certain resistance to the herbicide after the complete emergence, the effect of the herbicide is poor, and the best use temperature of the herbicide is between 20-35 degrees, and the effect of the herbicide will be reduced when it is too high or too low.
-
It can be packed in woven bags, which can hold a lot, and basically it is not easy to break or leak.
-
I feel that the most ordinary packaging is still the most practical. Pesticides don't need to be well packaged, the most important thing is the benefit of removing pests and diseases.
-
When packing, it is best to choose bottles, and be sure to pay attention to the sealing of the packaging, and at the same time there should be a production date and production approval number on it.

<>1. Acute toxicity: If not rescued in time, there will be life-threatening, this kind of herbicide enters the body by mistake or contact with the respiratory tract, and can appear in a short period of different degrees of poisoning symptoms, such as dizziness, nausea, convulsions, vomiting, spasms, dyspnea, incontinence, etc. 2. Subacute toxicity:
It often takes time for symptoms of toxicity to manifest, but the final presentation is often similar to acute toxicity and can sometimes cause local pathologic changes. 3. Chronic toxicity: After long-term ingestion by humans and animals, it will accumulate in the body, causing damage to internal organ function and hindering the normal physiological and metabolic process.
1. Toxicity characteristics of pesticide herbicides
The toxicity types of herbicides include acute toxicity, subacute toxicity, and chronic toxicity, and their toxicity characteristics are as follows:
1. Acute toxicity: refers to some more toxic herbicides, such as ingestion or contact with the respiratory tract into the body, in a short period of time can appear different degrees of poisoning symptoms, such as dizziness, nausea, convulsions, vomiting, cramps, dyspnea, incontinence, etc. If the rescue is not timely, it is life-threatening.
2. Subacute toxicity: In the process of long-term exposure to a certain dose of herbicide, it often takes a certain amount of time to show poisoning symptoms, but the final performance is often similar to acute toxicity, and sometimes it can also cause local pathological changes.
3. Chronic toxicity: although the toxicity of some herbicides is not high, but the nature is relatively stable, it is not easy to decompose and disappear after use, it can pollute the environment and food, and after long-term ingestion by humans and animals, it will accumulate in the body, causing damage to internal organ function and hindering the normal physiological and metabolic process.
2. What are the varieties of herbicidal pesticides?
1. According to the mode of action of herbicides, they can be divided into selective herbicides and biocidal herbicides. Among them, the selective herbicides include Gaicaineng, Flulelin, Prometrinet, Simazine, Guoer herbicides, etc., and biocidal herbicides are toxic to all plants, such as glyphosate.
2. According to the movement of herbicides in plants, they can be divided into contact herbicides (such as herbicides, paraquat, etc.), systemic conduction herbicides (such as glyphosate, prometrinet, etc.) and systemic conduction and contact comprehensive herbicides (such as chloricidal), etc.
3. According to the chemical structure of herbicides, they can be divided into inorganic compound herbicides (such as potassium chlorate, copper sulfate, etc.) and organic compound herbicides (such as promethonyl, cover grass energy, etc.).
4. According to the classification of herbicides, it can be divided into stem and leaf treatment agents (such as gacaocan, glyphosate, etc.), soil treatment agents (such as simazine, prometrinet, flulelin, etc.) and stem and leaf and soil treatment agents (such as atrazine, etc.).

It's like the old saying: a key opens a lock.
1. The development of herbicides is completed according to the characteristics of grass. For example, some grasses are broad-leaved, some grasses are coniferous, some grasses are annual, some grasses are perennial, etc., and the herbicides used are different depending on the characteristics of various grasses.
2. The same is true for insecticides, different insects should be used with different drugs to kill it, spring insects and summer insects have different characteristics, the medicine is different, and a drug can only kill one kind of insects.
3. Biology continues to evolve, and people also need to constantly develop new drugs to solve problems, so it is normal for there to be many types of drugs.
Chili peppers belong to the vegetable category and are annual or limited perennial herbs. The fruit is usually conical or oblong in shape, green when unripe, and turns bright red, green, or purple when ripe, with red being the most common. The fruit of chili pepper has a spicy taste due to the capsaicin contained in the peel, which can increase appetite. >>>More
There are many varieties of brandy in the world, such as apple brandy (Calvados civados in France), grape pomace brandy (Graba Grapa, Italy), cherry brandy, plum brandy, etc., these so-called "eau devie" (eau devie) together with wine form a colorful wine world, bringing infinite happy times to human beings. However, brandy is often used to make fresh grapes and then processed to form distilled spirits, so many people confuse it with the concept of wine. There are two main differences between brandy and wine: >>>More
