Product Information

Rattler herbicide is an advanced formulation containing the isopropylamine and potassium salts of glyphosate.  Rattler is taken up by foliage and translocated to underground roots, rhizomes and stolons, providing control of both annual and perennial grasses and broad-leaved weeds. Rattler is rapidly adsorbed onto particulate matter in soils and water and is quickly degraded by the micro-organisms present in soil and aquatic bottom sediments.  Until degraded, the active ingredient in Rattler, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater.

To maximise the safety of Rattler to the operator, consumer and environment, the label recommendations and the DEFRA/HSE/DETR publication “Code of Practice for using plant protection products” should be adhered to.

Symptoms on the weeds

Symptoms of treatment are generally first seen 7-10 days, or longer (if growth is slow), after spraying.  These take the form of leaf reddening followed by yellowing and are usually quicker to appear on grasses than on broad-leaved weeds.  Reaction of nettles is slow.

• Modern formulation of Glyphosate with new patented Twin Isomer technology for rapid weed knockdown and kill
• Inbuilt surfactants to improved target coverage while giving greater penetration of problem weeds with a shiny, waxy surface
• Following application, glyphosate is translocated from the treated leaves throughout the plant and to underground roots, rhizomes and stolons.
• Symptoms of weed death occur in 10-14 days. Gradual wilting and yellowing of foliage is rapidly visible in grass weeds, but are slower to appear in broad-leaved weeds
• Rattler is deactivated on contact with the soil. Re-planting trees and shrubs 7 days after application. Grass can be re-sown 7 days after application. 

Weed Timing

• Most perennial broad-leaved weeds are particularly susceptible to treatment when they are actively growing and shortly before flowering.
• Annual weeds should be growing actively at the time of treatment.
• Grasses should have at least 5 cm of growth.
• Broad-leaved weeds should have at least two sizable true leaves

Application notes and guidance:

For best results a rain-free period of 6 hours (preferably 24 hours) is required after application

Treating weeds which are suffering from drought stress may result in reduced efficacy

Extreme care should be taken to avoid spray drift as this can severely damage or destroy neighbouring crops and plants

Under conditions of drought, flooding, frost or high temperatures, disease or insect damage or weeds heavily covered with dust, where plant growth is restricted the efficacy of this product will be reduce

Recommended safety clothing / PPE; coveralls, chemical resistant gloves, boots & faceshield
