| Timeframe |
How Long Application timing varies across the country depending on time of sowing, soil temperature and size of weeds. Aim to apply when weeds are small, once clovers have a minimum of two trifoiate leaves and the is at least 50% ground cover.
|
| Plant back withholding |
Plant Withholding Where susceptible species such as brassicas and clovers are to be planted, it is advised not to sow for up to 28 days following application.
|
| Stock withholding |
Stock Withholding Delay grazing for 7-10 days after application to ensure the chemical has had a chance to start working. Some poisonous plants such as ragwort become sweet and more palatable after spraying and stock should NOT graze these pastures until the plants have died down.
|
| Barriers to effectiveness |
Barriers Rainfall
Rainfall within 8 hours following application may reduce the effectiveness.
Environmental conditions
Apply early rather than late when weeds are small, less than 5cm diameter and soil temperatures are above 12°C for better long term control. Best results are obtained when applications are made after several days of warm humid weather. |

Pasture Guard Elite is clover safe making it suitable for very young pastures containing seedling clovers.
Provides control of certain broadleaf weeds that are difficult to control with MCPB including: chickweed, cleavers, mayweeds, nettle, spurrey, storksbill twin cress and willow weed.
Pasture Guard Elite provides better control of seedling buttercups and thistles where phenoxy herbicide resistance is suspected.
Application
At all times you should refer to the Pasture guard Elite label.
Pasture Guard Elite is a selective herbicide with contact and systemic activity. It is mainly taken up by the leaves, so weeds must have germinated before spraying. Pasture Guard Elite works best when weeds are small (seedlings) and actively growing after several days of warm humid weather. Pasture Guard Elite must be used with sufficient water to ensure that all foliage of the target weeds is thoroughly covered. Use a minimum of 300L of water per hectare.
The addition of a non-ionic surfactant such as widespread at label rates will assist spray coverage and retention, but should only be used when specified in the label. DO NOT use a surfactant when spraying peas.
Mode of action
Pasture Guard Elite has two active ingredients.
MCPB is taken up by the leaves and translocated to the growing points. Plants that are susceptible to MCPB convert MCPB to MCPA, which accumulates in the growing points and disrupts cell division and growth. Plants such as clover and peas do not make this conversion, so are unaffected by MCPB.
Bentazone is absorbed mainly by the foliage and inhibits photosynthesis in susceptible plants. Legumes such as clover and peas are not susceptible to bentazone.
Storage and handling
- Keep out of reach of children.
- Store in accordance with NZS8409 Management of Agrichemicals.
- Store in the original container tightly closed in a locked, dry, cool area away from foodstuffs, fertilisers and seeds.
- Stores containing 1000L of Pasture Guard Elite are subject to signage and secondary containment, more than 1000L require emergency response plans.
- Please refer to the product label for product handling and storage details.
Shelf life
When stored appropriately this product should show no significant degradation for two years from the date of manufacture. Contact your supplier for further information about the use of any product that is older than this.
Mixing and compatibility
Add the required amount of Pasture Guard Elite to the partly filled spray tank with the agitation system running. Complete filling before adding any surfactant (if required), and maintain agitation throughout mixing and application. Do NOT add a surfactant unless specified in the Directions for Use.
Do NOT mix Pasture Guard Elite with any other herbicide, fungicide, insecticide, plant growth regulator or foliar fertiliser.
Additional information
When applying to new pasture, ensure clovers have at least 2 trifoliate leaves and weeds are small (2-6 leaf) and actively growing. Ensure there is at least 50% ground cover. It there is not sufficient ground cover there is a risk of clover damage from root uptake. Do not graze treated pasture for 7-10 days after application to give the chemical a chance to work.
