Tolerance of sugarbeets (Beta vulgaris L. ‘Mono-Hy A1’) to ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulphonate) was associated with rate of application and soil type. Yield of roots was significantly reduced by preplant-incorporated applications of 3.4, 4.5, or 9.0 kg/ha of ethofumesate to a sandy loam soil, but only the 9.0 kg/ha rate reduced the yield on a loam soil. Pinto beans (Phaseolus vulgaris L. ‘Idaho #111’) yielded normally when planted on a sandy loam soil within 4 to 6 weeks after ethofumesate was incorporated at rates of 2.2 to 9.0 kg/ha. Corn [Zea mays L. ‘Pioneer brand 3773 MFS(N) hybrid’] yields were reduced in proportion to the rate of herbicide applied 3 weeks before planting. In greenhouse studies, barley (Hordeum vulgare L. ‘Moravian’) and wheat (Triticum aestivum L. ‘Scout’) were about 10 times more susceptible to soil residues of ethofumesate than corn. Concentrations of ethofumesate in the soil as low as 0.1, 0.2, and 1.5 ppmw reduced the height of wheat, barley, and corn, respectively.

In the field, eight barley (Hordeum vulgare L.) cultivars tolerated postemergence applications of AC 222,293 [a mixture of methyl 6 and 2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl) m- and p-toluate] at 0.4 to 1.4 kg/ha. AC 222,293 at 0.4 kg ai/ha applied at the 1.5- to 2-leaf stage controlled wild oats (Avena fatua L. # AVEFA) 96%, whereas 0.7 kg/ha applied at the 3.5- to 4-leaf stage controlled wild oats only 93%. Sugarbeets (Beta vulgaris L.) but not alfalfa (Medicago sativa L.), corn (Zea mays L.), pinto beans (Phaseolus vulgaris L.), or sunflower (Helianthus annus L.), were injured when planted 6 to 8 months after fall applications of AC 222,293 at 0.4 to 1.1 kg/ha.

Preemergence and postemergence application of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazine-5(4H)-one] at 0.6 and 1.1 kg ai/ha controlled downy brome (Bromus tectorumL. ♯ BROTE) in winter wheat (Triticum aestivumL. ‘McDermid’) but caused considerable injury without the use of activated carbon over the seeded row. Activated carbon applied in 5-cm bands over the seeded row at 84, 167, and 336 kg/ha protected winter wheat at Pendleton on a silt loam soil. On a sandy loam soil, only a 336 kg/ha rate provided protection from metribuzin. Metribuzin toxicity to winter wheat was more difficult to neutralize when applied preemergence. Downy brome control was not reduced by carbon applied over the wheat row. The best treatment in this study was carbon at 336 kg/ha applied preemergence over the row followed by metribuzin at 0.6 or 1.1 kg/ha postemergence. A 10-week delay between preemergence carbon banding and postemergence metribuzin protected winter wheat from chemical injury.

The production and persistence of nine cultivars of lucerne were studied at the Mallee Research Station, Walpeup, Victoria, over three seasons. Hunter River, Siro Peruvian, and African lucerne were similar in yield, but Siro Peruvian was less persistent. The superior yield of these three cultivars over two accessions of Flandria, Du Puits, and Socheville was largely due to their greater winter production. Two lines of Canadian creeping-rooted lucerne were found to be entirely unsuited to this district. Hunter River and Siro Peruvian lucerne were also compared on a sand and a sandy loam soil at Walpeup. The relative production of the two cultivars was the same on the two soil types but the effect of soil type was marked. The production and persistence of lucerne grown on the sand was far superior to that on the sandy loam.

Stem melanosis of spring wheat (Triticum aestivum ’Park’) has often been found to be associated with Cu-deficient soils. The application of Cu chelate at 3.0 kg ha−1 of Cu to a Cu-deficient Black Chernozemic sandy loam soil reduced stem melanosis of Park wheat and increased grain yield.Key words: Copper deficiency, copper-deficient soils, copper fertilizer, Park wheat, stem melanosis

Tolerance of corn (Zea maysL.) to cyanazine {2-[[4-chloro-6-(ethylamino)-s-triazin-2-yl] amino]-2-methylpropionitrile} and atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] was compared when grown in Conover sandy loam soil. Reductions in seedling dry weight were obtained under both low and high soil moisture following preemergence and postemergence applications of cyanazine allowed to contact both plants and soil. During periods of active plant growth high soil moisture is favorable for rapid root uptake of cyanazine which causes injury to corn.
