Fungicides are typically divided into agricultural and household use, with agricultural fungicides being a category of pesticides used to control diseases caused by fungi, bacteria, and other pathogens. In this article, we will explore what agricultural fungicides are and discuss some of the most common types used in farming.
**First, based on the raw material source of agricultural fungicides:**
1. **Inorganic compounds**: These include substances like sodium dichromate, copper sulfate, zinc chloride, and cadmium chloride.
2. **Organotin compounds**: Examples include triphenylacetate and tributyl fluoride.
3. **Organic arsenic compounds**: Such as Tian'an (iron methyl arsenate), rice lining (calcium methyl arsenate), and thiram arsenic.
4. **Organophosphorus compounds**: Like aluminum triethyl phosphite, rice glutinous rice, and enemy famine phosphorus.
5. **Organic mercury compounds**: Including ethyl mercury chloride and phenylmercuric acetate.
6. **Organic sulfur compounds**: Such as allicin, mancozeb, thiram, and captan.
7. **Nitrogen-containing heterocycles**: This group includes benomyl, carbendazim, thiabendazole, tricyclazole, and many others.
8. **Benzene-based compounds**: Examples include biphenyl, chlorothalonil, and pentachlorophenol.
9. **Other compounds**: Such as perfluoroacetone, methyl bromide, and imidazole-based fungicides.
**Second, based on the use of agricultural fungicides:**
1. **Protective agents**: These are applied before the pathogen comes into contact with the plant. They prevent spore germination or kill spores that have already landed. Examples include Bordeaux mixture, mancozeb, and chlorothalonil.
2. **Curative agents**: These are used after infection has occurred but before symptoms appear. They can penetrate the plant and inhibit or kill the pathogen. Examples include carbendazim and methyl thiophanate.
3. **Eradicants**: These are applied directly to infected plants to kill the pathogen. Examples include fumigation arsenic and lime sulfur.
**Third, based on their behavior within the plant:**
1. **Systemic fungicides**: These are absorbed by the plant and transported throughout its tissues, providing 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 mainly used for protection and are less likely to cause resistance. Examples include copper sulfate, mancozeb, and sulfur.
Understanding the different types of agricultural fungicides is essential for effective disease management in crops. Whether you're looking for protective, curative, or systemic options, there's a wide range of products available to suit various needs.
