Edward’s approach to grassweeds
Initially, the black-grass at Troston Farms was so severe it was hampering yields. Today, however, he can hand-rogue it.
Historically, Edward’s approach has involved mole-ploughing and restructuring soils to improve drainage, spraying-off large patches where the battle has been lost, delaying drilling, using spring cropping, and a robust herbicide programme of Crystal + diflufenican plus Avadex pre-emergence. Edward has also been known to apply a sulfonylurea post-emergence in spring or late autumn.
Edward pays close attention to applications and has a farm policy of applying residual chemistry with 200l water/ha. This, he says, helps optimise coverage.
He will not drill wheat before mid-October and hasn’t needed to spray off any patches of black-grass for four years.
