  • Glyphosate is a wonderful post-seedling chemical herbicide in broadcost seeding nursery of Pinus taeda and P. elliottii, as well as in the nursery of P. massoniana and Chinese Fir. The applying time is: in the nursery of P. taede and P. elliottii it can be applied before the seedling height is 15 cm (June 30 th); in the nursery of P. massoniana it should be applied before the top shoot grows to a length of 1.0 cm, but if the seedlings grow to a height of over 5.0cm then the seedlings will be seriously damaged. Applying its application in Chinese Fir nursery have will hurt the seedlings a little.
