Extract

Many field studies have indicated the relative tolerance of cotton and other crops to certain chemicals used as pre-emergence weed killers. The possibility does exist, however, that the herbicide may cause injury to the crop when applied prior to emergence of the seedlings. The extent of injury will depend upon a number of factors such as rate of application, depth of seeding, penetration of the chemical into the soil, absorption of the chemical by the young plant and inherent tolerance of the species to a given herbicide. Implicit in each field test is the possibility that, under different conditions of rainfall, temperature and soil type, injury to the seedling crop cannot be ruled out. Some factors can be controlled to provide maximum safety to the germinating crop seeds, but others, such as weather conditions, are largely uncontrollable.
