However, res idue problems iD. relat ion to the growing crop and residual effect o"f the chemical in the soil ra.ises the question of any wide usage of this compound for broad-lea.ved weed and grass control in field crop rotations.

'!HE EFFECTIVENESS OF FALLANDSPRINGHERBICIDETREATMENTS FOR QUACKGRASS OONTROL IN CORN,1960. INTRODUCTIDN: Stanford N. Fertig !I (A Su.mmarr Report) In view of the diversity of management practices followed by farmers I the methods of Quackgrass control and the timing of applications :must also be different. With the chemicals presently aVa.uable, fall applications would have some definite advantages as regards plowing, planting and possible residue, which, without proper timing, could result in crop injury. EXPERIMENTAL METFDDANDPROCEDm.E: In the fall of 1959 and the spring of 1960, the herbicides in Table I were applied as foiliage sprays. The fall treatments were applied on October 8, 1959, and the spring treabnents on April 23, 1960. The fall treatments were applied on sod ground and plowed 30 days later. The spring treatments were applied on sod ground for the spring plowed half of the plot but was over-plowed ground on the fall plowed half of the plot. The spring treated plots were plowed 6 days after treatment. The cultural operations before planting were the same for all plots and all plots were planted to com, using the same variety and fertilizer rate on Juneh, 1960. The corn on a portion of each plot (fall and spring plowed) was cultivated two times dUring the growing season. During the growing season, visual observations and stand counts on Quackgrass were made on all plots. On September 8, 1960, silage yields were taken on all plots. RESULTSANDDISCUSSION: The most promising treatments for Quackgrass control were those including Atrazine, Simazine or Propazine as a spring treatment. The other combinations of treatments shown in Table I did not effectively control Quackgrass for the growing season or did not reduce the Quackgrass stand as determined by visual observations. In each instance the comparison was made with a check treatment. The most promising control of Quacltgrass was on the spring plowed plots. However, the broad-leaved weed and amual grass control was best on fall plowed plots. With the spring application going on plowed ground on these plots, better control was obtained on the annual broad-leaved weeds and annual. grasses.
