2,4-D Ester Herbicide
2,4-D Ester is a 2,4-D isobutyl ester (2,4-D IBE)-based herbicide formulated as an emulsifiable concentrate (EC). It is a selective, systemic, post-emergence herbicide used to control susceptible annual broadleaf weeds and sedges in crops such as rice, corn, and sugarcane. Philippine registered-product records list 2,4-D IBE formulations at concentrations around 410–491 g/L, depending on the specific product.
Product Details

- Product Type: Herbicide
- Formulation: Emulsifiable Concentrate (EC)
- Active Ingredient: 2,4-D Isobutyl Ester (2,4-D IBE)
- Typical Concentration: Approximately 400–491 g/L, depending on the registered product
- Herbicide Type: Selective, systemic, post-emergence

Product Benefits
- Helps control susceptible broadleaf weeds and sedges.
- Provides selective weed control in registered crops.
- Systemic activity allows the herbicide to be absorbed and translocated within susceptible weeds.
- Particularly useful as a post-emergence treatment when weeds are actively growing.
- EC formulation allows dilution and application according to label directions.
- Can be incorporated into an appropriate integrated weed-management program.
How 2,4-D Ester Works
2,4-D Ester contains 2,4-D isobutyl ester, a synthetic auxin-type herbicide. After application, the active ingredient is absorbed by susceptible plants and translocated to growing tissues. It disrupts normal plant growth and development, resulting in abnormal growth, loss of normal plant function, and eventual death of susceptible weeds.
Because it is selective, it can control susceptible broadleaf weeds and sedges while being tolerated by certain registered crops when applied according to the product label. Application timing and crop growth stage are important for achieving effective weed control and minimizing crop injury.
Target Weeds
2,4-D Ester is primarily registered for controlling:
- Annual broadleaf weeds
- Sedges
Philippine pesticide records list 2,4-D IBE products for broadleaf weeds and sedges in rice, corn, and sugarcane.
The exact weed species, crop, application rate, and restrictions should always be taken from the current registered label of the specific 2,4-D Ester product.
Recommended Use
Use 2,4-D Ester only according to the approved product label.
For effective weed management:
- Identify the target weeds before application.
- Apply when weeds are young and actively growing.
- Use the prescribed dilution and application rate.
- Ensure adequate coverage of the target weeds.
- Apply only to crops and growth stages specified on the label.
- Avoid spray drift onto sensitive crops and desirable vegetation.
- Follow the specified pre-harvest interval.
- Avoid unnecessary repeated applications.
- Rotate herbicide modes of action where appropriate to help manage herbicide resistance.
- Do not apply to crops or situations not covered by the registered product label.
Safety Precautions
- Keep out of reach of children.
- Wear appropriate personal protective equipment (PPE) during mixing and application.
- Avoid skin and eye contact.
- Avoid breathing spray mist or vapors.
- Do not eat, drink, or smoke while handling the product.
- Prevent spray drift onto neighboring crops, gardens, and other sensitive vegetation.
- Avoid contamination of food, feed, waterways, and aquatic environments.
- Store securely in the original container.
- Dispose of empty containers according to applicable pesticide regulations.
- Read and follow the product label before use.
