Avoiding growth checks in young grass and controlling a wide variety of weeds are beef and sheep farmers top priorities when it comes to spraying new sown leys with herbicide. This is according to a survey carried out by research company Independent Business Resource on behalf of Dow AgroSciences earlier this summer.
“These worries stem from the old days when farmers were relying on products based on different chemistry that was not as selective or safe as the newer ones used today,” says Dow AgroSciences grassland agronomy manager Brent Gibbon.
“Our new translocated product Leystar is designed to be sprayed onto new sown leys from as early as when three grass leaves have appeared. It also controls a wide range of weeds that are present at application from chickweed, mayweed and fat hen, through to seedling perennial weeds like docks, buttercups and thistles.
“Leystar is a welcome introduction for any grassland farmer reseeding. I am sure it will allow more reseeds to succeed, which is important when they are costing between £400 to £700/ha to produce.”
Leystar is a suspension emulsion formulation, which can be applied to new sown leys at 1 litre/ha any time from 1 February to 31 August. It comes in a 2-litre pack that treats two hectares (five acres). It is applied in 200 litres of water and is rainfast in two hours. Leystar will kill clover, but legumes can be stitched in three months after application.
Other survey results
The survey also highlighted that many herbicide applications to grassland (61%) are still being made using flat fan nozzles, despite the advantages of low drift technology such as air inclusion nozzles.
