GRASS LEYS SOWN WITH CLOVER

Triad™ SX® is safe on red and white clover and may be used in new grass leys sown with clover and where clover is included in undersown spring barley. Clovers in a sward may be checked following treatment but will recover. Apply Triad™ SX® from three leaves of the grass and once clover has reached three trifoliate leaves. In a change from the previous tablet formulation Triad™ SX® has been reformulated into FMC SX technology which is easy to use and allows a faster and safer washout procedure for sprayer operators. 

When applying Triad™ SX®, best results are achieved when weeds are small 
and actively growing.

Important:
Take care to avoid overlaps
Do not treat crops under stress, including from the following factors:
High diurnal temperature ranges
Drought
Waterlogged soils
