Introduotion<br />
This paper is a report on the etfectivene,s of the herbioides<br />
listed in Table lin oontrolling annual b~o,aleaf weeds and ahrlcial<br />
grasses in sweet oorn.<br />
Procedure<br />
Seneoa Golden sweet OOl'nwas planted in a sandy loam soil.<br />
5 June, 1961. Treatments were replioated se.en times in a rand,0<br />
mized block of single row plots paired with untreated plots.<br />
Sprays wel'e applied with one pass ot a .ma11p10t sprayel' at 40<br />
pounds pressure and 50 gallon8 per acr-e volume~ Planting al'P~oation,s<br />
of herbie1des were made 6 June, 1961, Jll'eemergenoe applioations<br />
were made 13 June, 1961.<br />
The prinoipalbroadlear weeds were: Wild rutabaga (Brads1oa<br />
~ L.), Spurry (sperpjula srvensis L.), Ragweed (AmbrosIa<br />
~m1si1folia L.), and Sma~tweea (P01asonum,pensSlvanIoum t.)4<br />
The prinoIpal annual grass wls Barnyar ,grass (Eo Inoofiloa '<br />
oruspjslli L.).<br />
Results<br />
Treatments that did not diffel' signifieantly in effeot on<br />
yield at the 5 pel'cent level from the standard treatment of 2<br />
pounds of atrazine per acre were: 6 and 8 pounds of Niagal'a 5178<br />
applied preemergenoe, planting applioation ot 10 pounds of either<br />
R-3408 01' R-3400, 01' 3 pounds or Ca801'0n, and h~hd weeding,<br />
Table 2.<br />
Treatments pl'oducing lowel'yields than the six best tl'eatments<br />
did so because of eithel' inadequate broad1eat weed control<br />
or a reduction in stand of oorn, Table 2.<br />
