Evaluation Of Bas 9052 & Bas 9021 For Control Of Johnsongrass (Sorghum Halpense) In Soybeans (Glycine Max), Sheryl Rogers
Evaluation Of Bas 9052 & Bas 9021 For Control Of Johnsongrass (Sorghum Halpense) In Soybeans (Glycine Max), Sheryl Rogers
Masters Theses & Specialist Projects
The lack of adequate weed control is one of the major problems encountered in soybean production. Johnsongrass presents one of the most serious weed control problems in the Southeastern United States. numerous herbicides are used in an effort to control johnsongrass, and research is still being conducted to find new herbicides for this purpose. Two of these herbicides are BAS 9021 [6,6-dimethyl-2,4-dioxo- 3[1-[2-(propenyloxy)amino]butylidene]-cyclohexane] and BAS 9052 [2-(n-ethoxybutyrimidoyl)-5-(2-ethylthiopropy1)-3- hydroxy-2-cyclohexen-1-one].
In 1978, johnsongrass control with BAS 9021 at 1.1 and 1.7 kg/ha in sim-le early postemergence or late postemergence applications, or in each of two split applications, was evaluated using the herbicide …

Powdery mildew control of grapes with fungicides. Location: Mount Barker Research Station. Black spot and downy mildew of processing peas - 80AL32. Facial eczema investigation. Facial eczema is a recognised myco-toxic disease of grazing stock in New Zealand. It is caused by a fungus Pithomyces chartarum growing on dead litter part of the pasture. The disease has become recognised as a risk to sheep in the Albany Region following reported losses in 1978. A pasture paddock at Cape Riche was sampled weekly by the Animal Division to determine fluctuations in spore numbers of P. chartarum. Comments: The fungus could readily …

Effect of stubble and seed infection on S. nodorum at Badgingarra. Fungicide timing on Septoria control.
Double cropping wheat was simulated by spreading stubble fragments collected from an adjoining paddock at 30 g/m2. Infected seed was from a 1979 sowing at Badgingarra, clean seed was pedigree Gamenya ex Merredin. Treatments were thus:- 1. Clean seed, no stubble. 2. Clean seed plus stubble. 3. Infected seed, no stubble. 4. Infected seed plus stubble. Plots were 10 x 25 m separated by equal sized barley buffers.

Influence Of Planting System On Surface Soil, Physical Conditions And Soil Water Relations, D Tennant
Experimental Summaries - Plant Research
Influence of planting system on surface soil, physical conditions and soil water relations. The availability of soil water for crop use can this way be influenced by planting system. Various aspects of soil water relations were examined in varying detail at three sites - Wongan Hills, Avondale and Merredin, over the 1979 and 1980 growing seasons. Some of this soil water data are presented here. The Department of Agriculture initiated a programme in 1977 to investigate and compare crop performance under several planting systems. This project was part of this programme and had as its objectives: 1. Measurement of soil …
