Response of Cotton (Gossypium hirsutum) to Preplant-Applied Hormone-Type Herbicides

Response of Cotton (Gossypium hirsutum) to Preplant-Applied Hormone-Type Herbicides

In a 3-yr field study on a Bosket silt loam, dicamba (0.3 and 0.6 kg ai ha-1) and 2,4-D amine (0.6, 1.1, and 2.2 kg ae ha-1) were applied at 3, 9, and 16 d before planting cotton. Most treatments applied 3 or 9 d before planting caused cotton injury and yield reduction. Replanting was necessary when...

Zusammenfassung:In a 3-yr field study on a Bosket silt loam, dicamba (0.3 and 0.6 kg ai ha-1) and 2,4-D amine (0.6, 1.1, and 2.2 kg ae ha-1) were applied at 3, 9, and 16 d before planting cotton. Most treatments applied 3 or 9 d before planting caused cotton injury and yield reduction. Replanting was necessary when 2,4-D at 2.2 kg ha-1was applied 9 d before planting, and all treatments except dicamba at 0.3 kg ha-1when applied 3 d before planting.
