Role of temperature in the activity of acetanilide herbicides on three Phaseolus taxa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: E. van Rensburgd --- , Republic of South Africa L.P. van Dyk --- , Republic of South Africa G.H. de Swardt --- , Republic of South AfricaAlachlor [2-chloro-N-(2,6 diethylphenyl)-N-(methoxymethyl) acetamide], metolachlor [2-chloro-N-(2-ethyl-6- methylphenyl)-N-(2-methoxy-1 -methylethyl) acetamide] and acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6- methyl-phenyl) acetamide], members of the chloroacetanilide herbicides, are used pre-emergence to control grasses and some broadleaf weeds. Two concentrations, i.e. 0,5 and 2 mg ai kg−1 of the... -
Role of temperature and water potential on the activity of some acetanilide herbicides on three Phaseolus taxa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: E. van Rensburg --- , Republic of South Africa L.P. van Dyk --- , Republic of South Africa G.H. de Swardt --- , Republic of South AfricaThe effect of three acetanilide herbicides on the hypocotyl-epicotyl growth rate of three Phaseolus taxa was studied at two temperatures and two water potentials. The study proved that, apart from the detrimental effects of the herbicides, low temperature and water... -
The effect of acetanilide herbicides on photosynthesis and respiration in isolated hypocotyl-epicotyl cells from three Phaseolus taxa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: E. van Rensburg --- , Republic of South Africa L.P. van Dyk --- , Republic of South Africa G.H. de Swardt --- , Republic of South AfricaThe effect of alachlor [2-chloro-N-(2,6 diethylphenyl)-N-methoxymethyl) acetamide], metolachlor [2-chloro-N- (2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide] and acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methylphenyl) acetamide] on photosynthesis and respiration of isolated 10-day-old hypocotyl-epicotyl cells from three Phaseolus taxa was investigated. Herbicide concentrations of 1×10−12, 1×10−10, 1×10−8, 1×10−6,1×10−4 and 5×10−3 M... -
Screening of some South African maize (Zea mays L.) cultivars for acetochlor tolerance
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: J. Allemann --- Department of Soil, South Africa P.M. Mphundi --- Department of Soil, South AfricaAcetochlor containing a safener is registered for pre-emergence use on maize to control mainly annual grasses. It is applied at rates of between 0.49 and 1.89 kg ai ha-~ on soils with a clay content from <10% to 55%. Some...
