WEEDCONTROL IN.STRAWBERRIES WI'DIEITAH, NEBURON, TRIEWINE ANDZY~ Jolin S. 8&11ey2 In the northeast strawberry fi.1ds are cu.tomari1y fruited only onc.. One of the chief reasons for this i. the failure of growers to keep weeds under control. The use of Sesone haa helped but under 'CllII8condition. results. bave been d1sappointing. Several other chemicals have been tried but none bas been widely used (1,2,3,5,6). Therefore, the search for a better weed control chemical for use in strawberry fields continues. Materials and Method. In mid-April, 1960, virus~frea plants of the variety Surecrop were s.t in plots 5 feet by 12 f.et. The mother plants were s.t2 feet apart, 5 to a plot and allowed to form matted rows. The materials t ..... d and rates per acre w.re as follows: Eptam 51 granular at 2 and 4 pounds; NeburoD 18.5~ W.P. at: 1 and 2 pounds; Trietadne 50%W.P. at 2 and 4 pounds and Zytron 25%on clay at 10 and 20 pound.. Each treatment was replicated four time.. . The plot. were hoed and cultivated until June 10 so that the plants would be thoroughly established before any treatments were applied. On June 10, after thorough cultivation and hoeing the Trietaaine and Neburon were sprayed over the plots using one pint of wat.r per plot. On June 13 the Eptam and Zytron for each plot was mixed with a double handful of dry •• nd and broadcast by band. The•• two material. were then cultivated in lightly with an iron rake. By mid-July some of the plots were getting very weedy, especially the untreated plots. Therefore, all the weeds on each,lotwere counted. S1Dce. very little gra.s appeared in any of the plots at t~s time or later, all the data will cover broadleaf weeds Oh1y. Those present were mostly purslan., Portulaca 01er~5~; red root pigweed, Amarant~~lt retroflexusj 1ambsquarters, ~~~ ~j and smartweed, Po1ygonumhydropiper. After the weed counts were made all plots were thoroughly cultivated, hoed and on July 26 and 27 all plots were re-treated. By September 23 some plots had become very weedy again. Therefore, the plot. in each block were ranked for weed population so that the results could be tested statistically by the rankit method (4). The most abundant weed at this t~e was commonchickweed, Stellaria media. After the ranking all plots were cultivated and hoed and no more chemi~applied either in the fall or lContribution No. 1328 of the Massachusetts Agricultural Experiment Station.

The outstanding material is Trietazine. The two pound rate seems to be just as good as the four pound. Eptam at four pounds per acre also gave sucb good control that ther~ is no significant difference between it and the two rat .. of Trietazine. The difference in weed control between the two rates of ·Tr1etazine and the other materials is significant but the differences betwee~ Eptam at four pounds per acre and the others is not. . . . .
