With winter wheat crops growing away quickly and variable weather windows for spraying, it is the last chance for growers to complete grass weed programmes, before both weeds and crops pass optimal growth stages, says Dow AgroSciences.
Stuart Jackson, herbicide specialist at Dow AgroSciences says: While the temptation is to rush to get the sprayer out of the shed as soon as a dry spell is forecast, operators should be careful not to compromise on effective application. Choose the right nozzle, spray quality, forward speed and boom height for your target weeds to ensure spring weed control applications are effective.
Pay attention to growth stages both of crop and target weeds to ensure youre not putting more pressure on a product than is necessary. The bigger the weed, the harder it is to control, Mr Jackson continues.
Despite the pressure to get the spraying done its important to apply when both crops and weeds are actively growing, ideally two to three days before and after application.
UNITE is effective on black-grass up to growth stage (GS) 24. Apply in 130-150 l/ha of water using a fine to medium quality spray. Late germinating and small black-grass plants that have not tillered may benefit from a lower water volume of 130 l/ha using a fine spray, to ensure optimal coverage.
With an extensive range of supported tank mix compatibilities, including many T1 fungicides, and excellent control of black-grass, brome, ryegrass and wild oats and a wide range of broadleaved weeds, UNITE offers flexibility at this challenging time of year.
Broadway Star is the product of choice for those with a focus on bromes, ryegrass or wild oats. Plus it provides extensive broadleaved weed control, including cleavers. Where wild oats in winter wheat are a concern, Broadway Star controls ACCase resistant strains and is highly cost effective.
