Product Review

Diuron is a widely used urea herbicide effectively controls annual grasses and broadleaf weeds. It primarily works through root absorption, and application before or early after emergence can achieve permanent weed suppression.Diuron is stable and widely applicable, commonly used in sugarcane fields, orchards, and non-cultivated areas requiring reliable and economical weed management.

Basic Information

Product Name: Diuron

Chemical Category: Urea Herbicide

CAS Number: 330-54-12

Molecular Formula: C4H11Cl2N4O2

Molecular Weight: 233.1

Appearance: White to white crystalline powder

Solubility: Slightly soluble in water, soluble in organic solvents

Stability: Stable under normal storage and field conditions

Mechanism of Action

Diuron inhibits photosystem II (PS II) by blocking electron transport during photosynthesis. This blockage prevents sensitive weeds from producing energy, leading to growth inhibition and ultimately plant death.

This herbicide is primarily absorbed by plant roots and systemically transported within the plant, making it most effective when applied before weed emergence or in the early stages of growth.

Key Benefits

Broad-spectrum herbicides

Long-lasting residual activity in the soil

Effective root absorption, ensuring stable yields

Economical and efficient large-scale application program

Suitable for integrated weed management programs

Formulation Options

Diuron is available in a variety of commercial formulations, including:

Wet powder (WP)

Suspension concentrate (SC)

Water-dispersible granules (WG)

Custom formulations are available to meet various regulatory and market requirements.

Safety and Operation

Use according to local label instructions.

Avoid spray drift onto sensitive crops.

Use appropriate personal protective equipment.

Store in a cool, dry, well-ventilated place.

Comply with environmental and groundwater conservation guidelines.

Market Value

Diuron remains a reliable herbicide option in many global markets, especially in areas requiring long-term weed control and cost-effective perennial crop and fallow management programs.

FAQ

Question 1: What type of herbicide is diuron?

Answer: Diuron is a urea herbicide, primarily used for pre-emergence and early post-emergence weed control.

Question 2: Is diuron a contact or systemic herbicide?

Answer: Diuron is a systemic herbicide, primarily absorbed through plant roots and transported within the plant.

Question 3: Which weeds is diuron most effective against?

Answer: It is most effective against annual grasses and broadleaf weeds, especially when applied before weed emergence.

Q4: Can diuron be used after emergence?

A: Yes, diuron can be used in the early stages of emergence, but the smaller the weeds, the higher the yield.

Q5: Is diuron suitable for resistance management?

Yes. Diuron can support resistance management programs by rotation or mixing with herbicides with different mechanisms of action.

Q6: Can diuron be used in orchards?

A: Yes, diuron is commonly used in orchards, applied by directional spraying or screen spraying to avoid crop damage.
