Clopyralid 95% tech (nc-025)
Chemical name: 3, 6-dichloro-pyridine-2-carboxylic acid
Structure:
Formula: c6h3cl2no2
Cas: 1702-17-6
Application:
Control of feverfew, nightshade, and umbelliferous. It is selective in gramineous plants. It is selective in many types of broad-leaved including brassic, sugar beet, flax, strawberry and shallot too. It also can mix with other herbicides to control other weeds such as annual weeds and perennial weeds.
Common Name Glyphosate
Chemical Name N-(phosphonomethyl)glycine
Molecular Formula C3H8NO5P
CAS NO 1071-83-6
EINECE NO 213-997-4
Application It is used to kill weeds, especially annual broadleaf weeds and grasses that compete with crops.
Fungicides are chemical or biological agents used to prevent or eliminate fungal infections in plants, animals, and humans. They play a crucial role in agriculture by protecting crops from diseases caused by fungi, which can significantly reduce yield and quality.
Types of Fungicides:
1. Contact Fungicides: These remain on the surface of plants and prevent fungal spores from germinating.
2. Systemic Fungicides: Absorbed by the plant, these move through its tissues to combat existing infections.
3. Protective Fungicides: Applied before infection occurs to prevent fungal growth.
4. Curative Fungicides: Used after infection to stop the spread of fungi.
Common fungicides include sulfur-based compounds, copper-based solutions, and synthetic chemicals like azoxystrobin and carbendazim. Some organic options, such as neem oil and bicarbonates, are also used in sustainable farming.
Herbicides are substances used to control unwanted plants, commonly known as weeds. They play a crucial role in agriculture by preventing weeds from competing with crops for nutrients, water, and sunlight. There are two main types of herbicides:
Selective herbicides: Target specific weed species while leaving crops unharmed.
Non-selective herbicides: Kill all plants they come into contact with.
Historically, weed control involved manual methods like tilling and altering soil conditions. The first major breakthrough in chemical herbicides came during World War II with the development of 2,4-D, which allowed for selective weed control in cereal crops.
Modern herbicides are widely used in agriculture, forestry, and even urban landscaping to maintain clear spaces and prevent invasive plant species from spreading. However, their use must be carefully managed to avoid environmental damage and resistance in weeds.
Paraquat is a non-selective herbicide. However, due to the lack of a specific antidote, the mortality rate after poisoning is high, the death process is long, and patients suffer greatly. There is a strong call for its ban in society. In order to safeguard people's lives and health safety and ensure the safe production and use of paraquat, the Ministry of Agriculture has successively taken relevant measures in recent years to strengthen the agricultural registration, production, sales and use management of paraquat products. Paraquat, with the chemical name 1-1-dimethyl-4-4-bipyridine cationic salt, is a fast-acting non-selective herbicide. It has contact killing effect and certain systemic effect, and can be quickly absorbed by the green tissues of plants, causing them to wither and die. It has no effect on non-green organizations.
Introduction:
Selective systemic herbicide. Salts are readily absorbed by the roots, whilst esters are readily absorbed by the foliage. Post-emergence control of annual and perennial broad-leaved weeds in cereals, maize, rice, sorghum, grassland, established turf, grass seed crops, orchards (pome fruit and stone fruit), cranberries, asparagus, sugar cane, forestry, and on non-crop land (including areas adjacent to water).

Chemical 2,4-D
Structure Formula
Common Name 2,4-D (BSI, E-ISO, (m) F-ISO, WSSA); 2,4-PA (JMAF)
CAS No. 94-75-7
CAS Name (2,4-dichlorophenoxy)acetic acid
Molecular Formula C8H6Cl2O3
Agrochemical Type Herbicide,phenoxycarboxylic acids
Mode of Action Selective systemic herbicide. Salts are readily absorbed by the roots, whilst esters are readily absorbed by the foliage. Translocation occurs, with accumulation principally at the meristematic regions of shoots and roots. Acts as a growth inhibitor.
Characteristics and Uses Post-emergence control of annual and perennial broad-leaved weeds in cereals, maize, sorghum, grassland, established turf, grass seed crops, orchards (pome fruit and stone fruit), cranberries, asparagus, sugar cane, rice, forestry, and on non-crop land (including areas adjacent to water), at 0.28-2.3 kg/ha. Control of broad-leaved aquatic weeds. The isopropyl ester can also be used as a plant growth regulator to prevent premature fruit fall in citrus fruit.
