Effect On Yield

Where winter wheat (Triticum aestivum L. ’Norstar’) was worked-down on 1 May and the plots reseeded to spring wheat immediately, no detrimental effect on yield of spring wheat was found. However, delaying this action until 15 May reduced the yields of spring-seeded wheat because of the harmful effect of decomposing winter wheat and late seeding. Moisture depletion by winter wheat was eliminated as a causative effect by light irrigations during May. Yields of rapeseed (Brassica campestris L. ’Candle’) were not so severely reduced by worked-down winter wheat. The harmful effect was significant only with 30 May cultivation and seeding date.Key words: Phytotoxicity, Triticum aestivum, Brassica campestris, worked-down

The effects of different densities of volunteer wheat (Triticum aestivum L. ’Neepawa’) on the yield of canola (Brassica campestris L. ’Tobin’ and B. napus L. ’Westar’), and the seed yield of the volunteer wheat were determined in field experiments conducted at Vegreville, Alberta and Scott, Saskatchewan. Hyperbolic models provided a good fit to the data in most instances and indicated that volunteer wheat can severely reduce canola yield. A model pooled over locations and years indicated that volunteer wheat populations as low as one plant m−2 reduced canola yield by approximately 1%. Yield loss predictions from the models were used to determine the economics of volunteer wheat control with herbicides. In some cases, revenue losses due to reduced canola yield could be alleviated when the value of the volunteer wheat was considered.Key words: Volunteer wheat, canola, rectangular hyperbola, multiple regression, economic threshold, volunteer cereals

Paraquat at 0.28 kg/ha effectively controlled barley (Hordeum vulgare L. ’Galt’), wheat (Triticum aestivum L. ’Neepawa’) and oat (Avena sativa L. ’Random’) in field trials conducted during 1982 and 1983. Grass control was excellent with paraquat and its activity was unaffected when it was applied in combination with either clopyralid, picloram, metribuzin, linuron, or chlorsulfuron. Slight reductions in paraquat phytotoxicity occurred in some instances when paraquat was applied in combination with commercially formulated mixtured of clopyralid plus 2,4-D, clopyralid plus MCPA or picloram plus 2,4-D, but grass control was still acceptable (90% or greater). However, a commercially formulated mixture of cyanazine plus MCPA consistently reduced the phytotoxicity of paraquat and rendered grass control unacceptable. Control of rapeseed (Brassica campestris L. ’Candle’) with paraquat and most paraquat mixtures was excellent in 1982 but was poor and variable in 1983.Key words: Wheat, barley, oat, rapeseed, zero tillage, chemical summerfallow

Control of barley (Hordeum vulgare L.) at Brandon and Lacombe, and wheat (Triticum aestivum L.) at Regina and Scott, in Canola (Brassica campestris L. and Brassica napus L.) with postemergence (three- to four-leaf) applications of BAS 9052 (2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)-propyl]-3-hydroxy-2-cylcohexen-1-one) mixed with Atplus 411F (0.5% vol/vol) were evaluated in 1979 and 1981. Control of barley and wheat was good to excellent with applications at 0.3 or 0.4 kg/ha and seed yields of canola were increased.Key words: Barley, wheat, canola, BAS 9052
