Weeds compete very aggressively with your crop for nutrients, energy (in the form of light) and water and usually they win! The result: reduced yields, reduced grain quality, lower profits. To minimise the impact on crop yield, it is recommended that Hussar is applied when weeds are small, during warm and moist growth conditions. Hussar controls a wide range of broad leaved and grass weeds e.g. chickweed, cleavers, annual poa. Hussar is particularly effective at controlling ryegrass.
