Agricultural chemicals (agrochemicals) are essential tools for modern farming, designed to enhance crop yields, protect plants from pests and diseases, and improve overall agricultural productivity. Here’s a detailed overview of the main product categories and specific examples offered by agrochemical supplier:

1. Insecticides
Insecticides are used to control and eliminate insect pests that can damage crops.
- Organophosphates: Such as Malathion, widely used for controlling a variety of insect pests.
- Pyrethroids: Like Cypermethrin, known for their high efficacy and low toxicity.
- Neonicotinoids: For example, Thiamethoxam, effective against aphids and whiteflies.

2. Fungicides
Fungicides help prevent and control fungal diseases in plants, reducing crop losses.
- Triazoles: Such as Tebuconazole, used extensively for diseases in wheat, corn, and other crops.
- Benzimidazoles: Like Carbendazim, effective against a range of fungal diseases.
- Copper-based formulations: For example, Bordeaux Mixture, used to control downy mildew in grapes and apples.

3. Herbicides
Herbicides are designed to control weeds that compete with crops for nutrients, water, and sunlight.
- Selective Herbicides: Such as Glufosinate, used to control broadleaf weeds.
- Non-selective Herbicides: Like Glyphosate, widely used for general weed control in various crops.
- Sulfonamide Herbicides: For example, Metsulfuron Methyl, used to control broadleaf weeds in wheat fields.

4. Plant Growth Regulators
These chemicals are used to modify plant growth and development, often enhancing yield and quality.
- Auxins: Such as Naphthaleneacetic Acid (NAA), used to promote root growth.
- Gibberellins: Like Gibberellic Acid (GA3), used to promote seed germination and fruit enlargement.
- Ethylene Agents: For example, Ethephon, used to promote fruit ripening.

5. Biopesticides
Biopesticides use biological resources, such as microorganisms and plant extracts, to control pests and diseases in an environmentally friendly way.
- Microbial Pesticides: Such as Bacillus thuringiensis (Bt), used to control various insect pests.
- Plant-derived Pesticides: For example, Rotenone, extracted from plants to control pests.
- Biological Fungicides: Like Bacillus subtilis, used to control plant diseases.

6. Fertilizers
Fertilizers supply essential nutrients to plants, improving soil fertility and crop yields.
- Nitrogen Fertilizers: Such as Urea, providing nitrogen for plant growth.
- Phosphorus Fertilizers: Like Superphosphate, promoting root development.
- Potassium Fertilizers: For example, Potassium Sulfate, enhancing plant resilience.

7. Soil Amendments
Soil amendments are used to improve soil structure and fertility, enhancing water retention and aeration.
- Compost: Organic compost increases soil organic matter and improves soil structure.
- Lime: Used to adjust soil pH, improving acidic soils.
- Gypsum: Used to amend saline soils, reducing salt content.

8. Seed Treatments
Seed treatments protect seeds from pests and diseases, promoting germination and early growth.
- Seed Coatings: Containing fungicides and insecticides to protect seeds and seedlings.
- Growth Regulators: Such as auxin-based seed coatings to promote germination and seedling growth.

9. Other Products
- Soil Disinfectants: Used to eliminate pathogens and pests in the soil.
- Rodenticides: For controlling rodent infestations in fields.
- Bird Repellents: To prevent birds from damaging crops.

Choosing the Right Agrochemicals
Selecting the appropriate agrochemicals involves several considerations:
- Crop Type: Different crops have varying needs and tolerances for chemicals.
- Pest and Disease Identification: Choose insecticides, fungicides, or herbicides based on the specific pests or diseases present.
- Environmental Impact: Opt for environmentally friendly, low-toxicity products to minimize ecological harm.
- Regulatory Compliance: Ensure that the chemicals used meet local legal requirements.

By carefully selecting and using agrochemicals, farmers can significantly boost agricultural productivity, protect their crops, and contribute to sustainable farming practices.
