As usual the wonderful UK weather has been predictably un-predictable this spring!
Following on from the on-going success of Zypar, combating broad leaved weeds in challenging conditions in winter cereals, our attention now turns to spring cereals. Despite the dry conditions many weeds are busting through such as black bindweed, cleavers, poppy, fumitory and fat hen.
Dow AgroSciences will be profiling two new grassland herbicides at Grassland and Muck 2017, and showing farmers how much grass they lose from having broad-leaved weeds like docks, thistles and nettles growing in their fields.
Leystar, designed for new sown leys and maize, controls a very wide range of weeds such as chickweed, bindweed, nightshade, charlock and fat hen, and seedling perennial weeds like docks, buttercups and thistles. It is particularly safe to use on young grass and can be sprayed from when three grass leaves have appeared.
A sharp drop in temperatures across the UK’s cereal-growing regions has left farmers facing a weed control problem.
After a period of unseasonably warm weather, a cold snap means cleavers – a key competitive weed in cereal crops – have become stressed and shut down.
Without the weed actively growing, traditional chemistry used for spring applications struggles to make headway in killing cleavers off.
“Cleavers are a top target for growers at this time of year when they are making a decision about what to put in the sprayer,” said Dow AgroSciences customer agronomist Stuart Jackson.
“Failing to take them out will lead to a yield penalty and leave a problem in the field for next season. Temperatures are all over the place but growers don’t have time to wait until the warmer weather returns.”
“The worst case scenario would be growers applying their traditional chemistry now, only for it to be ineffective and have to endure the expense of repeating the job.”
