Chlorpyrifos users reminded of stewardship importance

With the first foliar sprays of the yearimminent, farmers are being reminded of the need to abide by the stewardshipmeasures for all chlorpyrifos applications.

Whilst wheat bulb fly treatments are likely to be low due to limited pestpressure, the stewardship initiative, Say NO to DRIFT, advises care with thebroad spectrum insecticide as the season advances, particularly in slowerdeveloping crops in at risk areas.

James Knight from Dow AgroSciences, a membercompany of the stewardship consortium notes, Low drift nozzles and extendedbuffer zones, as detailed in the stewardship guidelines, must be adhered to forall applications of chlorpyrifos if we are to demonstrate wholesale industrysupport for this valued insecticide.

Despite the overall low levels of wheat bulbfly this year, later sown or slow developing crops, planted from Novemberonwards, will be vulnerable to wheat bulb fly egg-hatch if they have not yetdeveloped beyond the two tiller stage.

There is a particular risk for growers inthe North of England where wheat bulb fly eggs numbers have been recorded to behigher than in other parts of the country.

James adds, Farmers are also reminded tofollow stewardship guidelines when it comes to orange wheat blossom midgetreatments should pest levels demand control later in the season.

A regulatory decision that could lead to lowdrift nozzles becoming part of pesticide risk assessments is still pending,explains James.
