The influence of chemical and biochemical properties on the herbicidal efficiency of 3-cyclohexyl-5, 6-trimethylene uracil and 2-bromo-6'T-butyl-o-acetotoluidide

Creator:: Mackenzie, John William
Abstract:: Application of herbicides to the soil has become an important factor in the production of row crops. Economic production of sugar beet (Beta vulgaris), an important row crop, requires efficient methods of weed control. Two experimental herbicides, 3-cyclohexyl-5,6-trimethylene uracil (DP634) and 2-bromo-6't-butyl-o-acetotoluidide (CP32179), had shown promise in sugar beet screening...

Influence of soil moisture on movement of terbacil in soil

Creator:: Vesecky, John Francis
Abstract:: Previous field research with terbacil (3-tert-butyl-5-chloro- 6-methyluracil) has shown that early fall applications to dry soil performed better than did late fall or early winter applications to wet soil. Field and greenhouse studies were conducted to determine the effect of soil moisture content at time of application and the effect...

The lateral movement of cycloate as affected by three soil types and four methods of irrigation when applied to the soil by injection incorporation

Creator:: Stanger, Charles Earl, 1929-
Abstract:: Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate (cycloate)¹ is essential for satisfactory weed control with injection type incorporation in sugar beet (Beta vulgaris Linn.) production. Previous field experience with injection incorporation has indicated that sufficient lateral diffusion for satisfactory weed control has not occurred under all field conditions. Researchers who have been...

Effect of timing and rate of metribuzin on wheat and barley cultivars and on Italian ryegrass

Creator:: Durutan, Nedret
Abstract:: A field study was conducted in 1973 and 1974 to determine optimum timing of metribuzin (4-amino-6-tert-butyl-3(methylthio) as - tria.zine-5(4H)one) on winter wheat (Triticum aestivum L. 'Hyslop') for control of Italian ryegrass (Lolium multiflorum Lam. ). Herbicide treatments were applied at 5 different stages of growth of winter wheat. Metribuzin at...

The performance of N-(1,1-dimethylpropynyl)-3,5-dichlorobenzamide and other herbicides in controlling weeds in lettuce as affected by soil type and weather conditions

Creator:: Mitidieri, Agustin
Abstract:: Chemicals are being sought that can control weeds in lettuce under different environmental conditions, soil types and weed populations. The extensive or repeated use of a herbicide may lead to important changes in the weed population which call for new materials that can take care of the modified situation. In...

Toxicity of selected herbicides to the coho salmon Oncorhynchus kisutch (Walbaum) in comparative static and dynamic bioassays

Creator:: Juntunen, Erland T.
Abstract:: Comparison of the toxic effects of six herbicide formulations in simultaneous moving water and static water bioassays showed that mortality of coho salmon, Oncorhynchus kisutch (Walbaum), was less in the moving water tests. The moving water tests were conducted in troughs with powered paddlewheels while the static tests were conducted...

The use of 2, 4-d, paraquat and dinoseb for control of filbert (Corylus Avellana L.) suckers

Creator:: Reich, Jack Ernest
Abstract:: The control of filbert (Corylus Avellana L.) suckers by means of herbicides was investigated in three phases during 1968 and 1969. (1) Screening trials, on canned filbert trees in the greenhouse, to determine the effectiveness of various herbicides and concentrations in controlling vegetative growth. (2) A summary experiment in the...
