Dock problem?

Docks replace grass in a field; a 10% infestation means 10% less silage in the clamp. They have only 65% of the feed value of good grass and are generally unpalatable to livestock. Spraying docks two to three weeks after first-cut is an excellent opportunity to get good levels of control. Doxstar® Pro is a concentrated formulation controlling all species of docks in established grassland.

Beyond the label weeds with Leystar®

Cleavers, mayweeds, creeping thistle, charlock and volunteer oilseed rape are all label weeds listed for Leystar® in new leys and maize. However, Leystar will also give good control of chickweed, hemp-nettle, shepherd’s purse, corn chamomile and corn marigold in these crops.

Optimal size of key weeds controlled by Leystar in maize and new sown leys are listed in the table below:

There is also an excellent feature in the Grassland APP, which can give you this detail on all our products. To find it, select Products on the home screen and then the Weeds controlled. For these additional weeds, the information we give should not constitute a recommendation but an indication of what level of control might be achieved.

Call our Hotline if you want more information - 0800 689 8899 or UKHotline@corteva.com

The best control of buttercups is achieved if they are sprayed before flowering. However, replicated Corteva trials have shown useful control of creeping buttercup can still be obtained during flowering, but control can be 10% less than from a pre-flowering application. For best overall control, pre-flowering applications of Envy® at 2.0 L/ha is preferred.

Make sure you only use herbicides that have a label recommendation for use on grassland. If it is not on the label, then there is no backup from the manufacturer if something goes wrong and it is an illegal application putting cross compliance in jeopardy. Follow this rule when using adjuvants too.

Q) What can I use to control Umbellifers (Apiaceae), such as cow parsley and hogweed in grassland?

A) Although not label weeds, Grazon® Pro should give useful control of Umbelliferous weeds. If weeds have started to flower, then top them to remove the flowering stems, and spray the regrowth two to three weeks later.

Taking time to control thistles in established grassland now will prevent them spreading seed this summer and causing bigger infestations to deal with next spring. Where thistles are the main weed problem Thistlex®, which has been specifically formulated to kill these tough perennial weeds, including the Spear, Creeping and Marsh varieties, provides an ideal solution.

Grazing intervals and what they mean

Herbicides used at label rates and sprayed on grass are not generally toxic to livestock. However, most herbicides have grazing and feeding restrictions stated on the label that limit the use of the area for livestock feed for a specified time after treatment. All Corteva grassland herbicides have a grazing interval of just seven days, which is much shorter than for most other grassland herbicides.

Livestock that consume feed in areas treated with such herbicides will probably not become ill from ingesting the chemicals, but they could retain them in their systems. Attention must be given to grazing restrictions outlined on the product label, as these will prevent residues that could prevent the meat or milk from livestock from being marketed. Certain unpalatable or poisonous plants, such as ragwort, treated with certain herbicides may become more palatable to livestock. Be certain that livestock are kept out of areas where poisonous plants have been sprayed until the plants have completely dried up.

The Corteva Grassland App features a decision tree which enables users to find the best solution for grassland weeds in different situations, whether it is a new ley or established grass, for grazing or cutting fields, or for boom or hand-held application

Pioneer Brand 1188

A Key Advantage of Pioneer multiple species/ multiple strain grass silage inoculant Pioneer Brand 1188 over other grass inoculants.

The quality of grass silage is determined by numerous factors including:
* Grass quality
* Weather preceding and during harvest
* Fertiliser application rates and timings
* Harvesting speed and clamp management practices
* Feed –out practices
* Additive used

The ability of bacterial strains to grow and dominate the fermentation of any grass silage depends on:
* The quantity and types of water soluble carbohydrates available (i.e. the different types of sugar)
* The osmotic pressure which is a consequence of the dry matter %
* The pH levels as the fermentation proceeds
* The combination of bacterial strains and whether sufficient numbers have been applied

The ability of Pioneer Brand 1188 to utilise the biggest possible range of sugar types

The types of sugars (e.g. maltose, sucrose, cellobiose etc.) within grass plants vary widely depending on the proportion of different grass species within a ley i.e. perennials ryegrasses, timothy, clovers etc. One of the purposes of grass silage inoculants is to convert sugars to lactic acid more efficiently than would otherwise happen otherwise. Different inoculant products have a varying capability to utilise the different types of sugars found in grass. Pioneer Brand 1188 probably has the widest capability of any, see Table 1, which goes towards making it one of the most effective grass silage inoculants that can be applied to grass in the UK. Table 1. Range of sugar types utilised by Pioneer Brand 1188 versus a leading single strain competitor product (source; Pioneer Brand Research).

Tractor found parked up ‘with its engine running and no one in it’

  • 797

Written by Agriland Team

A tractor was left running and unattended while its driver was in a nearby shop buying lunch, a local police team in the UK have noted, highlighting the risks involved with such an action.

The unattended tractor was discovered by members of Dorset Police, outside a Tesco store in Blandford Forum, in England, last Thursday (October 15).

Taking to social media to highlight the matter, Dorset Police said:

When we visited Tesco’s in Blandford we didn’t expect to find a £110,000 [€121,800] tractor parked up near the entrance with its engine running and no one with it.
“We soon located the driver leaving Tesco’s with a meal deal.

“There’s absolutely...
