239 <strong>Weed</strong> Control and Residual Effects of Simaz1ne and of Atrazine Applied to Soil Prior to Planting ~$ery Stock A. M. S. Pridham, Cornell University Simazine and atrazine have both been used in wettable powder and granular formulation in two series of tests since J.951in plantings of evergreens (~ and Thuja) in Cornell nursery areas. The 1957 series of plants were rototilled and replanted in 1959. Rototilling has continued throughl961. The originaJ. plan of the plots is no longer visible from the weed growth or lack of it. 'Evergreen crop gro'l-rth is normal. Red l~idney beans were planted. in JUly 1961 in soil that had not been treated with triazines as well as in the old plot areas. Germination and growth were similar in both sections of the field, indicating that the soil was essentially free of triazines in the area of the bean root zone. A second nursery area was treuted in 1959 to till sod before planting nursery crops. Simazine and atrazine were applied JUne .21 and 22, 1959 at two rates, 5 and 10 pounds of active ingredient framlCeach of two formulations (wettable powder and granular) as well as surfaoe· application and in- corporation of the herbicide by rototilling 3-4 inches immediately following planting. During the summer of 1959 timothy sod was eliminated from treated plots except when simazine was used on the· sod surface in granular form without rototilling. Dandelion was st1muJ.e.ted in she and dark green color. Bindweed was released but re-invasion by seedling weeds was of minor proportions. In 1960 half of each 10 x 10 I plot was rototilled and the nursery indicator plants, Ligustrum oValifolium, EuOnymus fortunei, Pachysandra terminalis and Forsythia intermedia were planted in the freshly rototilled soil. The indicator crops oats, buckwheat and later red kidney beans were also planted. Typical growth response of these test crops to triazines was found only at the 10 pound level. Not all plants of an indicator group responded within a plot. Growth of beans was normal in soil samples taken to the greenhouse in fe.ll 1960 for testing indoors under soil moisture at field capacity from intermittent misting. June observations in 1961 indicated very little residual response in test crops. EuOnymus fortunei foliage in granular simazine plots at 10 pound level showed yellow margins on a few leaves in young growth typicaJ.of triazine injury in this and other crops including ~ and Taxus. A single strip was rototilled in June 1961 at right angles to 1959 and 1960 rototilling. Red kidney beans were planted in a single row through each rototilled strip. Growth and color of the red kidney beans in the untreated controls and in the triazine plots were very similar. Samples of 10 bean plants at flowering stage were cut at the soil level and green weight taken
