106. 5. <strong>Weed</strong> Control - Predominantly a grass problem. Und~r the conditions of this experiment neither irrigation nor seed treatment had any significant effect. a. Broadleat weed control. Liquid formulations in general gave better weed control than granular formulations. b. Grass control. Liquid formulations containing Randox were superior to liquid CIPC. Liquid and cranular Randox were equally effective in reducing grass counts. Mixtures of granular Randox and granular CIPC resulted in reduced grass control. Randox T granular and liquid at 6 lbs. were not too effective in reducing grass counts. Onion yi'?lds indicate, however, that there was enough aupp r e.aet on of grass gr~th tf\ obt a fn ,good onion yields. -
PRE-fREATINGSOILS, APOSSIBLE.TECfiNIQU1Fon \In:],]-INGVEGl,TABLES , R. D. Sweet and Joseph Cialone Department of Vegetable Crops, Cornell University, rthac~, d.Y. A selective herbicide tha.t will kill a wide range of weed species without danger to the crop, and one whose performance is not unduly influenced by either soil or environment, is the goal of many llorkers. Obviously, there are very few such chemicals available at present for weeding' vegetable crops. Thus, there is a need for additional techniques by which weeding can be accomplished safely without resorting to costly hand labor. The purpose of this report is to present a few limited research r€sults regarding the feasibility of pre-planting chemicals treatments for several vegetable crops. Experimental In a series of preliminary tests on sandy loam soil, certain individual plots from earlier treatments were utilized by replanting the initial crop. The plots chosen had given excellent weed kill but had seriously damaged or killed the first planting. The soil was raked by 'hand just prior to the second planting. A summary of these preliminary test results is presented in Table 1 From these observations, it was clear that several chemicals having high initial weed killing ability, but which injured crops, might possibly be rendered nontoxic in a sufficiently short period of time to warrant their use as preplanting treatments. As a partial follow-up of these results, greenhouse tests are being conducted with 7442and 8043to determine if possible the specific length of time they remain toxic. Rates of 4 and 6, and 2 and 4 pounds for 7442and 8043 respectively were sprayed on flats filled 2" deep with greenhouse potting soil. One series was planted immediately to timothy and broccoli. A duplicate series was planted at weekly intervals for four successive weeks. Hercules 8043lost its toXic action in approximately three weeks. However, 7442still showed toXicity in the fifth planting. A field test was conducted in which plantings of several vegetables werE: made at time of treating and at one and two weeks later. The individual plots were 6' x 15' and each contained spinach, cabbage, lettuce, carrot sand tomatoes. A separate series was used for each planting date. There were two replications. Crop response and control of weeds were rated approXimately six weeks after the first planting. In ("eneral, weed control was excellent for all materials. However, galinsoga was prevalent and this pest was not controlled by either EPTC or St. 2061. The plots were not re-worked between the initial treatment and the subsequent plantings.
