ProClova XL contain two active ingredients – Rinskor and amidosulfuron – which together provide the widest spectrum of weed control in new sown leys. Where pastures are been reseeded this spring, it is critical that they are sprayed with a post-emergence spray soon after reseeding to eliminate the weeds and allow the grass and clover to establish.
“The ideal timing for ProClova XL is about six to eight weeks after reseeding” said Chris Maughan, Technical Manager with Whelehan Crop Protection, distributors of ProClova XL in the Irish market.
“The grass should be at the tillering stage with three trifoliate leaves on the clover at the time of application,” explains Chris. “And the weeds should be small and actively growing, this ensures that they are eliminated out of the sward early and prevents them from smothering out the grass.
“ProClova XL controls a wide range of weeds, including chickweed, docks, and other annual weeds including fat-hen, red dead nettle and redshank.
“Chickweed, if not controlled can totally smother out the grass. If these fields are not sprayed, the chickweed will continue to flourish, killing out the grass seedlings which then allows other weeds such as docks, thistles and buttercups to germinate. The end result will be a very poor pasture and a wasted investment.”
Chris also highlighted the damage docks can wreak on a new reseed.
“Killing docks at the seedling stage is vital,” he said. “This ensures total kill and prevent the docks from establishing a deep taproot over the coming years, making them much more difficult to kill.”
Larger weeds
Where weeds have emerged before the grass, and are large, or where spraying gets delayed, ProClova XL can be used at the higher established grassland rate (one co-pack to treat 2ha) to target these large weeds once there is over 90% ground cover of both the weeds and grass present. This will ensure a better kill of those bigger weeds especially docks.
Ensure active growth
It is very important to apply ProClova XL during periods of active growth to get the best weed control. So ideally wait until temperatures are above 8°C at night for a minimum of three days before and after the application of ProClova XL. This would be important where applications are made in early spring.
ProClova XL is available in a box containing two bottles – ProClova and XL. ProClova contains the herbicides, Rinskor and amidosulfuron, while the XL bottle contains an adjuvant oil which improves the reliability of weed control, also providing maximum safety to both the grass and clover. Both products must be applied together.
Proclava XL key points and best practice advice
Docks at seedling stage.
Use from April to October in new leys.Rate in new sown leys: 85g + 165ml/ha (one pack treats 3ha).In established grass or where ground cover is greater than 90%, use the higher rate 125g + 250ml/ha (one pack to 2ha).Controls key weeds, including docks, chickweed, fat-hen, redshanks and red dead nettle.In established grassland it also controls dandelions, buttercups, plantains, cow parsley and hogweeds.Rainfast in one hour and livestock should be kept off for seven days posttreatment (in the absence of ragwort).Use from the tillering stage of the grass and when the clover has three trifoliate leaves present.Clover safety: a transitory effect (leaf deformation/growth inhibition) may be seen following application, but full recovery will follow after two/three grazings.
Ideally, swards should be grazed in the following weeks after applications to allow light get to the base of the crop, which in turn helps the clover to grow.
Red clover: when used on grass leys containing red clover, ProClova XL should be applied in the year after establishment – so reseeds sown last autumn containing red clover can be sprayed this spring.
