Maize Wheat Sorghum Broadleaf Control Systemic Herbicide 2,4-D Amine SL OEM

2,4-D is one of the most widely used selective herbicides for controlling susceptible broadleaf plants in agricultural, turf, pasture and non-crop systems.

Chemical Name: 2,4-Dichlorophenoxyacetic Acid

HRAC/WSSA Group: Group 4 – Auxin Mimics

• Field crops
• Pastures and rangeland
• Turf
• Rights-of-way
• Forestry
• Aquatic sites
• Certain fruit and vegetable crops

2,4-D is a systemic phenoxy herbicide designed mainly for the management of susceptible broadleaf species. It is available commercially in different chemical forms including amine salts, choline salts, esters, and acid formulations.

• 2,4-D Amine 480g/L SL
• 2,4-D Amine 720g/L SL
• Other registered 2,4-D formulations

2,4-D acts as an auxin mimic, disrupting normal auxin-regulated development and leading to abnormal tissue growth and eventual plant death.

1. 2,4-D is absorbed by susceptible foliage
2. Herbicide moves toward actively growing tissues
3. Normal auxin signaling becomes disrupted
4. Cells divide and expand abnormally
5. Leaves and stems become twisted or distorted
6. Vascular function is disrupted
7. Normal growth stops
8. Susceptible plants gradually die

Typical symptoms in susceptible plants include:

• Leaf curling
• Stem twisting
• Abnormal bending
• Swollen tissues
• Distorted new growth
• Chlorosis
• Growth suppression
• Gradual tissue collapse

2,4-D is primarily used for broadleaf control while many grasses are more tolerant when applied at registered rates and crop stages.

• Corn
• Small grains
• Sorghum
• Pastures
• Rangeland
• Turf
• Rights-of-way

Apply when susceptible broadleaf plants are young, actively growing, and not under severe stress.

Grass crops may tolerate 2,4-D well at certain stages but become more sensitive during reproductive growth periods. Always follow label specifications for application timing.

Although systemic, good coverage remains necessary for optimal performance. Poor coverage may cause reduced absorption, uneven treatment, and partial suppression.

2,4-D can injure sensitive broadleaf crops at relatively low off-target exposures. Sensitive plants include grapes, tomatoes, vegetables, fruit trees, ornamentals, and non-tolerant soybean varieties.

• Follow label wind speed restrictions
• Use appropriate nozzle selection and droplet size
• Maintain correct boom height
• Observe buffer zones
• Avoid temperature inversions
• Maintain separation from sensitive crops

Different 2,4-D products may contain amine salts, esters, choline salts, or acid forms, which differ in volatility, solubility, handling, and environmental behavior.

• 2,4-D Amine 480g/L SL (Soluble Liquid)
• 2,4-D Amine 720g/L SL (Soluble Liquid)
• Ester Formulations

2,4-D belongs to HRAC/WSSA Group 4. Resistance to auxin-mimic herbicides is increasing globally, requiring proactive resistance management.

• Rotate different herbicide modes of action
• Use registered effective mixtures
• Rotate crops
• Monitor survivors
• Use mechanical management where practical
• Prevent surviving plants from producing seed

2,4-D formulations can be supplied through OEM and private-label production where local registration permits.

• Brand name and customer logo
• Bottle design and package size
• Label language and market-specific artwork
• Outer carton customization

• 250mL
• 500mL
• 1L
• 5L
• 20L
