Broad-leaved crops present a completely different target to cereals, with horizontal leaves interlocking into a closed canopy. Persuading the spray into that canopy is tricky – often only 10-15% of spray ends up where it's needed. Big drops hardly get below the surface, but fine drops can ride in horizontally on air turbulence.
