GLYFOS GOLD is a water-soluble, non-selective, non-residual herbicide for the control of most annual and perennial grasses and broad-leaved weeds. The product is absorbed by the foliage and translocated throughout the plant and root systems. Visible symptoms, such as gradual wilting and yellowing are usually obvious within 3 to 7 days of application to annual weeds, but not for 14 to 21 days on perennial weeds. Complete browning and root deterioration may require 20 to 30 days, this process will take longer in cooler weather.

GLYFOS GOLD is inactivated on contact with the soil.

 

For best results a rain-free period of 6 hours and preferably 24 hours is required after application of this product.

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.

Lime, chemical or natural fertilisers or other pesticides should not be applied before treatment or to treated areas for at least 5 days before or after application of GLYFOS GOLD.

GLYFOS GOLD is inactivated on contact with soil, by binding to soil particles. All crops may be planted or sown at specified intervals after treatment with GLYFOS GOLD. A slight growth retardation following germination may be seen if seeds are sown by direct drilling amongst decaying treated vegetation, roots, rhizomes or stolons.

The action of GLYFOS GOLD will be slower in cooler weather. This product should not be used under frosty conditions while weed growth is reduced by natural senescence.

Half fill clean spray tank with clean water, add required quantity of product and mix well; add remaining water.

DO NOT use mechanical agitators. Place the filling hose below water level to prevent excessive foaming and remove immediately after filling to prevent back-siphoning. When tank mixing with other products recommended on the label add the other product before adding GLYFOS GOLD, then add the remaining water.

DO NOT STORE, MIX OR APPLY THIS PRODUCT FROM AN UNLINED OR GALVANISED STEEL TANK. Do not leave mixtures in spray tanks over long periods. Ensure that spray tanks are thoroughly ventilated.

It is important when treating perennial weeds that there is a full emergence of healthy green foliage and active growth at the time of application. The efficacy of this product is increased if the leaf surface for absorption is large.

Common Couch is particularly susceptible at the 4-5 leaf stage, where there is about 10-15 cm of new growth, when tillering and new rhizome growth is starting. 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 sizeable true leaves.

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 reduced.

 

GLYFOS GOLD may be applied to all areas which will be planted with food and feed crops, pre-harvest to wheat and oats intended for milling and barley intended for brewing. CONSULT PROCESSOR BEFORE USING ON CROPS INTENDED FOR PROCESSING.

NEVER APPLY PRE-HARVEST TREATMENT TO CROPS GROWN FOR SEED.

Barley intended for brewing and contract grown crops should only be treated following prior approval from the grain merchant.

Strains of some annual grasses, e.g. Black-grass, Wild-oats and Italian Rye-grass, have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.

Do not use glyphosate repeatedly in the same field over several years, as selection of resistant biotypes can take place and may become prevalent. No extra surfactant should be added if the product is to be applied using a rotary atomiser sprayer.

 

Use any equipment which can apply at 80-250 1/ha as a BCPC defined Medium or Coarse quality spray with a pressure ranging from 1.5 to 2.5 bars with 80º or 110º nozzles.

Pre-harvest applications should be made using high clearance tractors with narrow wheels and crop dividers, where spray boom can be raised to the height just above the top of the crop.

For most applications 200-250 1/ha water volume should be used. Spray pressure (typically 1.5-2.5 bars) must be adjusted and related to tractor speed, water volume and nozzle type. However, specific low volume nozzles may be used with a reduced water volume ranging from 80-120 1/ha. When using low volume nozzles, spray pressure and tractor speed should be adjusted.

A typical speed range would be 4-9 km/hour. When applying pre-harvest to crops, a low speed to avoid excessive bounce is recommended.

All spray equipment should be calibrated before use particularly if nozzles have been changed. Check at least one nozzle from each side of the boom. Before starting spray application be sure to check that;

the boom is level

the boom height is correct for the particular application

all nozzles along the boom are aligned at the correct angle to the forward direction of the tractor.

 

Select one of the following applicators;

CDA Boom and CDA Lightweight Microdrop,

Girojet,

Dual-Option Sprayer, Hydraspin

Applications should be made using a water volume of 40 1/ha , at a speed of 4-9 km/h with a droplet diameter set at 200-300 µm, equivalent to the BCPA definition ‘Medium’or ‘Coarse’. The spray equipment should be correctly calibrated according to the manufacturers instructions.

 

Knapsack sprayers may be used in forestry, orchards, setaside land and land not intended to bear vegetation and pre-cultivation. Spray volumes normally range from 200-300 1/ha, but may be reduced to 100-150 1/ha if low pressure nozzles have been fitted. Spray quality should be adjusted to a “medium” or “coarse” spray as defined by BCPC.

When using a knapsack sprayer with a total capacity of 10 litres, applying at 4.0 1/ha with a spray volume of 200 l/ha, gives a concentration of 2%, thus requiring 0.2 litres of GLYFOS GOLD in 9.8 litres of water. A 10 litre spray volume will cover a 500 m2 area using a 1m wide swath and a 1m/sec walking speed.

 

Weedwiper Applicator may be used in Orchards, Non-Crop and Aquatic areas.

Do not exceed the following dilutions: Weedwiper Mini – 0.7:2 dilution with water; other weedwipers – 0.7:1 dilution with water.

 

The applicator must be fitted with a solid stream nozzle, either a Spraying Systems 0006 or a Delevan LF 6.0. Set the gun to apply 2.0 ml of neat GLYFOS GOLD® per cut

 

The applicator must be fitted with narrow angle cone nozzles, TG3 or TG5 or solid stream nozzle tips either a Delavan LF 6.0 or Spraying Systems 0006.

Set the gun to deliver 4 ml per squeeze and select the concentration of GLYFOS GOLD according to usage recommendations. A dose of 4 ml should be applied for each 5 cm diameter of tree stump.

 

Be sure that all spraying equipment is functioning correctly and that equipment is maintained in accordance with manufacturers instructions. Ensure that any damaged, malfunctioning or worn parts are replaced before re-using the spray equipment.

 

Always clean spray tanks and all parts of the equipment adequately after use, using the recommended

detergents to be sure to avoid contamination with residues. Contamination with product residues could damage crops when the sprayer is next used for another pesticide.

 

Before using GLYFOS GOLD for control of aquatic weeds in or near waterways read the official recommendations entitled “Guidelines for the Use of Herbicides on Weeds in or neat Watercourses and Lakes”. This document may be obtained from Department for Environment, Food and Rural Affairs (DEFRA), Scottish Executive Environment and Rural Affairs Department (SEERAD), The Department of Agriculture Northern Ireland and the National Assembly for Wales Agricultural Department (NAWAD).

Users must consult the appropriate water regulatory body (Environment Agency)/Scottish Environmental Protection Agency before using this product near water and must obtain their permission before using this product to control aquatic weeds.

Maximum concentration of active ingredient in treated water should not exceed 0.2 parts per million, or such lower concentration as the appropriate regulatory body may require. When using GLYFOS GOLD following label recommendations, water subjected to spray drift may immediately be used for irrigation.
