Adama Diurex Herbicide (Diuron 80% WP):
Long-Lasting Pre-Emergence Weed Control for Plantation & Field Crops
Reliable Residual Herbicide for Broadleaf and Grassy Weed Management
Diurex Herbicide is a powerful pre-emergence and early post-emergence herbicide containing Diuron 80% WP, designed to provide long-lasting control of both annual grasses and broadleaf weeds. It works by inhibiting photosynthesis in susceptible weeds, stopping their growth soon after germination. Because of its strong residual soil activity, Diurex forms a protective herbicide layer in the soil that prevents weed seeds from establishing.
Diurex is widely used in sugarcane, cotton, citrus orchards, tea plantations, coffee estates, and non-crop areas where long-term weed suppression is required. Farmers prefer it for its extended control period, broad-spectrum activity, and compatibility with integrated weed management programs.
Its systemic action through the roots ensures weeds are controlled at the early stage, reducing competition for nutrients, sunlight, and soil moisture, which ultimately supports healthier crop growth and improved productivity.

Diurex Herbicide Features and Benefits
Broad-Spectrum Weed Control
Controls a wide range of annual grasses and broadleaf weeds, reducing early crop competition.
Long Residual Activity
Creates a protective herbicide barrier in soil that prevents new weed seedlings from emerging.
Root Absorption Systemic Action
Weeds absorb the herbicide through their roots and foliage, which stops photosynthesis and leads to gradual weed death.
Reduces Manual Weeding Cost
Helps farmers reduce labor expenses associated with repeated manual weeding operations.
Improves Crop Yield Potential
By eliminating weed competition during the critical early crop growth stage, crops can utilize nutrients and water more efficiently.
Suitable for Plantation Crops
Commonly used in orchards, tea gardens, and plantation crops where long-term weed suppression is needed.
Mode of Action
Diuron belongs to the Photosystem II inhibitor group of herbicides. It works by blocking the electron transport chain in photosynthesis. When weeds absorb the herbicide through their roots, the photosynthetic process stops, preventing energy production and eventually leading to plant death.
Because the herbicide remains active in soil for an extended period, it controls both emerging and newly germinating weeds.
Usage and Crop Recommendations
| Crop | Target Weeds | Dosage / Ha (Kg) | Dilution in Water (L/Ha) | Waiting Period |
|---|---|---|---|---|
| Sugarcane | Annual grasses and broadleaf weeds | 2 – 3 kg | 500 – 700 L | 60 Days |
| Cotton | Broadleaf weeds and grasses | 1.5 – 2 kg | 500 L | 60 Days |
| Citrus Orchards | Mixed weeds | 2 – 3 kg | 500 – 800 L | 60 Days |
| Tea Plantations | Annual weeds | 2 – 3 kg | 500 – 800 L | 60 Days |
| Coffee | Broadleaf and grassy weeds | 2 – 3 kg | 500 – 700 L | 60 Days |
Method of Application:
Apply as soil spray or directed spray before weed emergence or during early weed growth stage.
Best Application Timing:
Apply on moist soil after sowing but before weed emergence for maximum effectiveness.
Rain Fastness:
Approximately 4–6 hours after application.
Safety and Handling
-
Avoid spraying near water bodies and fish ponds.
-
Use protective gloves, mask, and clothing during application.
-
Do not allow spray drift to sensitive crops.
