Aerial bulblet control was excellent ($>$90%) with either herbicide regardless of application timing (March 21, April 8, and April 29) and significantly better than the standard treatment of 2,4-D $\\{$(2,4-dichlorophenoxy) acetic acid$\\}$. However, control of developing underground offset bulbs was less complete, and was found to be application time dependent. Much greater control of offset bulbs occurred when these herbicides were applied in late March or early April as compared to the April 29 treatment date. There was a positive rate response (8.8 to 1.0 g/ha) at the two earlier dates, but not at April 29. These herbicides also affected the germination and viability of the bulbs that were produced.","The selectivity of $\\sp $C-DPX-M6316 between tolerant wheat and susceptible wild garlic does not appear to be related to differential penetration. Absorption after 144 h was 63% for wheat and 76% for wild garlic. Absorption of DPX-M6316 in wheat and wild garlic was inversely correlated with concentration (200 to 1000 ppmw). Further experimentation determined that concentration affect was occurring at the leaf surface, probably caused by herbicide crystallization. However, translocation of $\\sp $C in wild garlic was more extensive than in wheat and concentrated in the major meristematic region (bulb axis). Both wild garlic and wheat metabolized $\\sp $C-DPX-M6316. The rate of metabolism in wheat was faster with significantly more $\\sp $C found as insoluble residue and soluble metabolites at 48 hours.","Another growth chamber study conducted on field grown wild garlic plants transplanted at regular 14 day intervals (March 25 to May 20) found that $\\sp $C-DPX-M6316 translocates to developing underground offset bulbs and scape. The amount of absorption after 144 hours ranged from 30 to 50%, increasing with plant age. Translocation of absorbed $\\sp $C was also more extensive as plants aged. The pattern of $\\sp $C movement in wild garlic changed with plant age, and appeared to follow paths of assimilation.
