l!!!! Experiment A factorial experiment with 3 replications wa. conducted on a Merrimac sandy loam, part of which had not been fertiUzed fn eeveral yean. The soU was Umed in AprU 1961 to bring it up to a p8:,of about 6.0. A 10-6-4 fertilizer, with 50 percent of the nitrosen in or saDie form, was applied to the 9 ft. x 21 ft. plots at rates of 0, 333 or 1,000 Ibs. per acre and disked in. Three days later (April 18, 1961), three'to five plants of the followins types and ases were planted into the plots: 199 !!!2! cuspidata - once (2 yr.) and twice (5 yr.) transplanted Taxu. ~ Mcksi - once transplanted (2 yr.) I.!!!!! canadensis - twice (4 yr.) and three times (5-6 yr.)transplanted Ligustrum ovalafolium • once transplanted (2 yr.) Eu0nY!llUs radicans • once (2 yr.) transplanted Granular simazine was applied over the soil a¢ rates of 2, 4, and 8 pounds of active insredient per acre with a lawn spreader. Simazine applications were made either at 2 or 7 week. after transp1antins. Injury evaluations were made by three peraons on July 14 and srowthof'lome p1antB was measured in the fall. control plots not tr.ated with sima.iDe were hoed at 4- to 6-week intervals during the season and at the same time, elcaped weeds were removed from the simaztne treated plots. ' RESU~S ANDDISCUSSION Greenhouse Experiment Twoweeks after iniUatioD of the test, LiIU!trum began to exhibit, chlorosis in the no fertilizer treatments. By the -Irit of August markad differences in shoot growth and size and color of l.aves of Ligu.trum were seen. The plante without f ertUh.r had small,.chlQtotic leaves and weak .hoots. The plants in the mediulllfertility level lII!4ev1sorou. growth, , leave. were normal size and medium,to light green ia· color. The Ligu,tr, plants in the highfertl1ity level made vigorous growth, leaves were 1arae and dark green. Neither!!!2! nor ..I!!!S.! exhibited foliage difference. or growth response to the fertilizer IeVeIs. ' Characteristic I1madne injury symptomson L~lfl!trum were lOBSof . chlorophyll on leaf edges, deve10pins to browning oftha edges, and death of entire leaves in extr8118 injury •. RatiDgs of deareeOf injury were made on AugustlO. TberaUnss in Table 1 ,showthat the 8IIOUntof injury to Ligu.trum was markedlY influences by the fertility treatments. Tbe most striking influence of fertility 'levels was seen at the i-pound rate of simadnewhen s,tilvereinjury was exhibited at the lowest fertility and no injury at the highest fertility level. It was also.tnteresUns to note that one pound ofsimazine at low fertility gave comparable iafary to four pound. of 8imazine at high fertility. . I!!2!, and'Tsus, failed to exhibit injury symptom. from any of the treatments. '.
