The trials were carried out during 1969 and 1970 to study the chemical weed control on the forest nursery by preemergence applications with MO-500 (2, 4-dichloro 6-fluoro 4-nitro diphenylether).
MO-500 was more effective than large rates of nitrofen for killing large crabgrass (Digitaria adscendens Henr.), dayflower (Commelina communis L.), ladysthumb (Polygonum persicaria L.), prostrate spurge (Euphorbia supina Rafin.) etc. and kept the experiment area free from weeds for 11/2-2 months at rate of 0.3-0.4cc/m2 (25% emulsion). All seedlings of AKAMATSU (Pinus densiflora S. et Z.), HINOKI (Chamaecyparis obtusa S. et Z.) and SUGI (Cryptomeria japonica D. Don) were no injury.
