Depitox 500 Selective Herbicide 5L

Depitox 500

MAPP no. 17597

Active Substances: 500g/l 2,4-D

Depitox is a systemic penetrant selective herbicide for the control of many broad-leaved weeds including Ragwort in managed amenity turf and amenity grassland situations, such as golf courses, playing fields, roadside verges and ornamental lawns.

Control of ragwort weed is best achieved when the plant is in the rosette stage.

Instructions for use

Where to use

• Amenity grassland - Areas of semi-natural or planted grassland subject to minimal or non-intensive management including airfields and predominantly grassed railway embankments and roadside verges.
• Grassland - Short and long-term grass leys and permanent pasture, which may be grazed and /or cut for subsequent animal consumption. Includes use on newly sown leys and moorland for grazing
• Managed amenity turf - Areas of frequently mown, (i.e. mown at least one a week) intensively managed turf, including fields being used for turf production. May include areas for public use including all types of sports turf, golf greens, tees and fairways.

When to use

Apply to actively growing grass (normally between April to September) that has been established for a minimum of 12 months.

• Annual weeds are more susceptible at the seedling stage
• Perennial weeds are more susceptible when the flower bud is forming

How to use

• Apply at a rate of 2.8 - 3.3l/ha in 100 - 1000l/ha water to amenity grassland, grassland or managed amenity turf
• Apply using vehicle mounted or handheld spray equipment using a medium spray quality nozzle
• Top dressing ten days before treatment will assist with weed control and subsequent recovery of the sward

Additional Information

• Livestock must be kept out of treated areas for at least 2 weeks following treatment and if ragwort is present, until there is no visible sign of the dead weed
• Do not apply during rain or if rain is expected
• Do not mow, roll or harrow for four days before or after application
• Do not apply immediately before or after sowing any crop
• The first four mowings after treatment must be composted for at least six months before use
• Do not apply to crops which are suffering from stresses
• Avoid contact with non-target plants

Active substances

2,4-D

Bio-Chemical Mode of Action: 2,4-D belongs to the synthetic auxins group of herbicides.

Synthetic auxins work by inducing rapid abnormal cell growth and development in the stems, petioles and leaves of susceptible plants causing cell bursts and ultimately cell and plant death.

Mobility: 2,4-D is a systemic penetrant which means that the active substance can be translocated downwards through the plant within the phloem (sugar conducting tissues) and upwards through the plant within the xylem (water conducting tissues).

Application timing: Systemic auxins are best applied when the weeds are actively growing. They are generally more effective when target plants are younger and in their vegetative phases.

Resistance: The incidences of resistance to synthetic auxins remains relatively low which is assumed to be because the herbicide has multiple sites of action.

However, resistance to synthetic auxins has been observed globally with 36 species being confirmed as resistant as of 2017. Best management practices, such as alternating with products with a different mode of action and using cultural weed control methods, will help to reduce the risk of further resistance.
