Abstract:

CS-1 applied to branches of six woody species caused greatest damage when plants were in immature foliage. Four herbaceous species grown in soil with incorporated CS-1 showed maximum seedling damage when agent applications were made within four weeks prior to planting. Greenhouse screening tests on 29 woody and 41 herbaceous species at dosages of 5.6 and 28 kgha showed the herbaceous group to be more susceptible to foliar damage than woody species and to exhibit a greater range of variability in effects of CS-1. Only three woody species showed foliar damage in excess of 20 from treatment at the high dosage eight herbaceous species had greater than 50 damage at the corresponding dosage. Cereal grains and conifers appeared to be more resistant to damage than other plants tested.
