Four -..-' pounds of Trietazine produced signifioantly fewer 081'rots than all other treatments, and 4 pounds of CIPC produced significantly fewer carrots than. 4 po~ds of Daothal and 10 pounds of Zytron. Weight per topped oarrot di-dnot differ statistically in Zytron .. Dacthal, Karsll, or Amiben plots. The high weight per oarrot in Trietezine and CIPC plots can be attributed to decreased competition between surviving, carrots r~sulting from reduction in carrot stand. Except for 8 p.ounds of Daothal and 4 pounds of Trietazine, weed control ratings corresponded fairly well with yield, Table 2. Twopowids of Amiben did not,ig~ve. ss,tisfs:otory weed control; all other treatments gave,'atleas~, ac eep ta ble' ooritr01, Table 5. 1 In a post-emergence teat, 4 or 6 pounds per acre of Solan, 3, 4, or 6 pounds of Dicryl, and 3, 4, or 6 pounds of Kersi1 did no t differ significantly in effect on yield, number of carrots per plot, or weight per topped carrot. All rates of these herbicides produced yields signifioantly higher than'check, Table 6. B. Sguash Pre-emergence application of 3 pounds per acre of DNBP, 10 pounds Zytrm, and 6 pounds Amiben (granular) did not differ siglifioantly in 'effect on either -yield or number of gourds per ,piot of Golden Delicious squash, Table 7. Gourd weight was significAn~ly higher in DNBP, Zytron, and Amiben than in check plots. DNBP endZytrondld not differ significantly in effect, but average gpurd weight was lower in Amiben than in DNBPplots. This difference in weight is presumably associated with difference in degree of weed -control, Table 7. - Conclusions Ten pounds of Zytron per acre, 4 to 8 pounds of Dacthal, and 4 pounds of Amiben show promise for pre-emergence application in carrots. Zytron, in the present test"was outstanding. rh post-emergence te~ts in carrots,' Solan, Dicryl, and Karsil at rates .from 3 to 6 pounCis per acre, did not differ-significantly in effect on yield, stand, or average weIght per topped carrot. Karsil gave numerically lower yields than either Solen or Dicryl. Pre-emergence epplicQtion to Golden,Delicious squash of 3 pounds ot DNBP, 10 ppunds of Zytron, and 6 poundso! Amiben did notdiffe~ significantly in e~fect on yield. Weight per gourd was :signif .1cantly higher in DNBP'than ~n Amiben plots. All herbicides produced significantly heavier gourds than check.
