FORMULATION

GLYPHOSATE- CHEMISTRY

Glyphosate acid is herbicidal, but insoluble in water

When reacted with metal or amine it forms a salt. One or more of

the hydrogen atoms is replaced by the metal cation. The salt is

soluble in water.

How the salts compare….1

Isopropylamine (IPA)

•Most commonly used salt

•480g IPA salt yields 360g acid

Limits on ai concentration so no very high load materials

Viscous at very high loadings

•Salt is intrinsically safe to plant tissue

Surfactant choice influences uptake, translocation and COSHH rating

Roundup Biactive

Amenity Glyphosate 360 White Label and Generics

Trimesium (sulfonium or sulfosate)

•Salt is intrinsically toxic to plants cells causing yellowing

•Symptom development faster but lower translocation

•Poor COSHH rating - Occupational Exposure limits needed

•No aquatic use

Touchdown – GONE

Di-ammonium salt

•Fast acting, efficiently translocated and good rainfastness

•Good on broad-leaved targets

•Clean COSHH rating but harmful to fish

(8)

How the salts compare….2

Ammonium salt Very high loads possible saving packaging and storage (up to 68%)

•Fast acting, very efficiently translocated and good rainfastness

•Good on broad-leaved targets

•COSHH rating Irritant due to high loading of ai

Roundup Max Glyphos Dakar

Potassium salt •More acid per gram of salt (440g K salt yields 360g acid)

•High load liquid formulations possible (up to 58%)

Low viscosity at high loading

•Salt is intrinsically safe to plant tissue

•Surfactant choice influences uptake, translocation and COSHH rating Roundup Klik/ Ace/Energy Roundup ProBiactive Roundup Ultimate Roundup Metro Roundup FLEX

(9)

Hvorfor Kalium Salt ?

Lav molekylevægt

440g Kaliumsalt = 360g acid

Sammenlignet med 480 g Isopropylamine salt

Lav viscosity = hurtigere tømning af dunk

Fleksibel til højere koncentration af glyphosate

(10)

How the surfactants compare….1

Ethoxylated tallow amine surfactant (ETA)

• Old technology and cheap to produce

Aggressive to the plant cuticle and causes fairly fast symptomology but less translocation

• Rainfastness >6 hours and up to 24 hrs

Needs extra surfactant at low rates

Tank mix options very limited

• Poor COSHH rating – Irritant or Harmful

Alkyl Phosphate Ester surfactant also known as APE or Phosphate esters • Anionic surfactant

Tissue safe with intermediate in speed of symptomology and translocation.

• Non-hazardous

•Long term control of perennials better than ETA but not as good as Biactivators

Not as active gram-for-gram active ingredient as most other formulations, especially at low rates so watch rate comparisons

(11)

How the surfactants compare….2

Bioactivators

(Blend of Quaternary Ammonium Compound and humectant)

Symptomology slower, due to the lack of tissue damage on leaf entry, but translocation is higher

• Improved broad-leaved weed activity (cf ETA & APE)

• Rainfast in 2-6 hours

• Non-hazardous

Does not require extra surfactant at low rates

Very good tank mix compatibility

UNIQUE, PATENTED MONSANTO TECHNOLOGY

Alkyl-poly glucoside (sugar ether)

Non-ionic and non-aggressive surfactant, bringing slow uptake (it is the TMS salt that damages

epidermal cells)

•Low unit surfactant activity prevents high-load formulations

•Rainfastness of 6 hours

(12)

How the surfactants compare….3

Transorb •Increased cuticle permeability

Delivers excellent uptake and improved penetration and translocation so better in marginal conditions

Rainfast from 1 hour

•Intermediate load (45% w/w) less packaging etc

•COSHH-friendly, non-hazardous formulation

No extra surfactant needed at low rates

•Tank mixes better than ETA

UNIQUE, PATENTED MONSANTO TECHNOLOGY

Alkyloxylated cationic

surfactant

•Excellent uptake, penetration and speed of activity

•Dry formulation offers packaging benefits

•Rainfastness from 1 hour

Allows high load formulations (68% w/w)

•Irritant

Good tank mix compatibility
