Applications

2,4-D Isooctyl ester (also called 2-ethylhexyl ester) is a selective, systemic herbicide used for post-emergence control of broadleaf weeds in crops like cereals (wheat, barley, corn, rice), sugarcane, pastures, and turfgrass.

 

1. Target Weeds

  It effectively controls:

•   Annual & perennial broadleaf weeds (e.g., pigweed, lambsquarters, ragweed, thistles, dandelions, clover, bindweed).

•   Brush & woody plants in non-crop areas.

 

2. Application Methods

A. Agricultural Use (Crop Protection)

•    Cereals (Wheat, Barley, Corn, Rice)

  •    Rate: 300-600 g a.i./ha (varies by weed pressure).

  •    Timing: Post-emergence, when weeds are young (2-5 leaf stage).

•    Sugarcane & Pastures

  •    Rate: 500-1000 g a.i./ha for tough perennials.

  •    Avoid grazing for 7-14 days after application.

•    Turf & Lawns

  •    Used in mixes for dandelion, clover, and plantain control.

B. Non-Crop Areas (Fence Lines, Industrial Sites)

•    Higher rates (1-2 kg a.i./ha) for brush control.

C. Aquatic Weed Control (Limited Use)

•    Some formulations approved for floating weeds (check local regulations).

 

3. Mixing & Compatibility

•    Often tank-mixed with other herbicides (e.g., glyphosate, dicamba, MCPA) for broader weed control.

•    Use non-ionic surfactants (NIS) or crop oil concentrates (COC) to enhance efficacy.

 

4. Key Advantages

   Better rainfastness than amine salts (less wash-off).
   Stronger on tough weeds (e.g., bindweed, thistles) than 2,4-D amine.
   Lower volatility than butyl ester, reducing drift risk.

 

5. Precautions

•    Drift risk: Use coarse sprays, avoid windy conditions.

•    Crop sensitivity: Can harm cotton, grapes, tomatoes, and legumes (dicot crops).

•    Resistance management: Rotate with other MOA (e.g., ALS inhibitors, glyphosate).

 

6. Example Commercial Products

•    Weedar 64 (Nufarm)

•    Dacamine (Dow AgroSciences)

•    Various generics in emulsifiable concentrate (EC) formulations.
