Fungicides are generally categorized into agricultural and household use. Agricultural fungicides, a type of pesticide, are specifically designed to control diseases caused by fungi, bacteria, and other pathogens. In this article, we will explore what agricultural fungicides are, as well as some of the most commonly used ones.
**First, based on the raw material sources of agricultural fungicides:**
1. **Inorganic compounds**: These include substances like sodium dichromate, copper sulfate, zinc chloride, and cadmium chloride.
2. **Organotin compounds**: Examples are triphenylacetate and tributyl fluoride.
3. **Organic arsenic compounds**: Such as Tian'an (iron methyl arsenate), rice lining (calcium methyl arsenate), rice foot green (zinc arsenate), and thiram arsenic.
4. **Organophosphorus compounds**: Includes aluminum triethyl phosphite, ethyl aluminum, and various types of rice glutinous rice products, as well as enemy famine phosphorus.
5. **Organic mercury compounds**: Like ethyl mercury chloride, phenylmercuric acetate, and ethyl mercury phosphate.
6. **Organic sulfur compounds**: Such as allicin, dasenium, mancozeb, thiram, thiophanate, methyl Tobuzin, captan, and others.
7. **Nitrogen heterocycles and other nitrogen-containing compounds**: This group includes benomyl, carbendazim, thiabendazole, tricyclazole, triadimefon, fluconazole, and many more.
8. **Benzene-containing compounds**: Examples are biphenyl, hexachlorobenzene, chlorothalonil, and various derivatives like pentachlorophenol and 8-hydroxyquinoline.
9. **Other compounds**: Includes perfluoroacetone, methyl bromide, chloropicrin, tebuconazole, flusilazole, imazalil, and many others.
**Second, based on the application method of agricultural fungicides:**
1. **Protective agents**: Applied before the pathogen comes into contact with the plant, these agents inhibit spore germination or kill them, protecting the plant from infection. Examples include Bordeaux mixture, mancozeb, and chlorothalonil.
2. **Curative agents**: These are applied after the pathogen has infected the plant but before symptoms appear. They can penetrate the plant tissue and either kill or suppress the pathogen. Examples include carbendazim and methyl thiophanate.
3. **Eradicants**: Used to eliminate pathogens already inside the plant. Examples include fumei arsenic and sulfur mixtures.
**Third, based on their behavior within the plant:**
1. **Systemic fungicides**: These are absorbed through leaves, stems, roots, or seeds and then transported throughout the plant. They provide both protection and treatment. Examples include carbendazim, metalaxyl, and triadimefon.
2. **Non-systemic fungicides**: These remain on the surface of the plant and do not move internally. They are mostly protective in nature and less likely to cause resistance. Examples include copper sulfate, mancozeb, and sulfur.
Agricultural fungicides play a crucial role in crop protection. If you want to learn more about them, be sure to check out the **pesticide network** for more detailed information.
