The selectivity of some herbicides in bulb growing

, : The selectivity of some herbicides in bulb growing. Acta Horticulturae 23: 305-311

In field trials on coarse sandy loam soil (o.m. 1-2%) at Lisse, tulip Edith Eddy roots were treated with linuron at 0.75 kg/ha, pyrazone at 1.95 kg/ha and simazine at 0.5 kg/ha. All treatments resulted in heavy damage during the flowering season, early dying down of the plants and a 20-35% reduction in bulb yield. Pyrazone and simazine also damaged hyacinths and reduced bulb yield by 50-60%. Linuron at 0.75 kg/ha reduced yields by 10-20% but lenacil at 1.22 kg/ha was safe.
