Work done by Kaye&:Wiggans21 ind:1cated that the effectiv.ess of certain herbicides ' was enhanced when used in coaPinetion with aspha1t~ch. Experimental Four tests were carried out duriIig the 1961 growing season at Ithaca. The sandy loam soil was ploved, diskedand harrowed with a meeker to prOVide a uniformly f:Lne s~ bed. The randomized plots were eaeh 3 x 15 feet and rep.l.:lcated two to four t1meso.epending on the nature of theJt.,1t. The herbicides were applied with a ~ proessure-operated Small-~l,ot spraye. 1' •.

In total; seyendifferent~heJilJ,cals were exam1Jledin three categories relating to the mulch: under the mulch, ~ with mulch an4:;no mulch. A fourth.C)~check category was that of no mulch and no herbicide. Application of herbic;l.de':fllI.d mulch was on an overall basi.s. In the first test two rates of mulch were tested. Since no differences were observed" only one rate wasused m subsequept -tests. Crops were varied according to chemical. SQlIlfl:werechosen on the be,sie. of present herbic:Ldal practices but. several sensitive grops were selected as ,indicators of chemical. toXicity or &et1v;l:ty. The foUl'. tests were started respectively on JU~ 16, July 7-10, Augl1$;tl 7, and September 1. !JPaper No• 469of the~partmentof Vegetable Crops, Cornell University,-tthaca, gj~;~duate Assistants, Department of Vegetable Crops, Cornell University .'
