This book was released on 2013-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the field study 20 weed species were registered and determined in seedling alfalfa and 36 weed species in established alfalfa. Efficacy of herbicides in seedling alfalfa was ranged of 94.0% (imazethapyr) to 97.5% (imazamox-1.2 L/ha) in 2006, and 95.0% (imazethapyr) to 98.7% (imazamox-1.2 L/ha) in 2007, respectively. Efficacy of herbicides in established alfalfa was ranged of 91.8% (pronamide) to 98.4% (metribuzin-1.0 kg/ha) in 2007, 93.1% (imazetapyr) to 97.3% (metribuzin-1.0 kg/ha) in 2008 and 92.1% (imazetapyr) to 97.3% (metribuzin-1.0 kg/ha) in 2009, respectively. In the end of alfalfa exploitation period, a greenhouse experiment was conducted to detect the soil residues of metribuzin, imazethapyr and pronamide applied in established alfalfa stand by a bioassay using wheat. Detection of herbicide residues was determined from soil samples collected from depths of 0-5, 5-10, 10-20 and 20-30 cm. Most of the herbicides did not significantly affected plant density, height and fresh weight of wheat plants in any soil depth. Exceptions was pronamide, which significantly reduced wheat plant density, height and fresh weight of wheat at 10-20 and 20-30 cm depth.

Download or read book Factors Influencing the Performance of Bromoxynil 4 2 4 DB Or a Companion Crop for Weed Control in Seedling Alfalfa written by Ferrin D. Leavitt and published by . This book was released on 1970 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the factors influencing the performance of bromoxynil, 4(2,4-DB), or a companion crop for weed control in seedling alfalfa were studied in the greenhouse and at field locations in Farmington and Logan, Utah. The effect of application rate, stage of growth, temperature, and soil moisture on the phytotoxicity of bromoxynil and 4(2,4-DB) to alfalfa and weeds were studied. Alfalfa yields were increased by 4(2,4-DB) at all rates and stages of application. All rates and stages of bromoxynil treatment except the one-fourth pound per acre three to four trifoliate application resulted in alfalfa yields below that of the control. The use of a companion crop was not conducive to the growth and development of alfalfa although it did control the weeds. Bromoxynil at all rates and at both stages of application resulted in effective mustard control. Mustard control in the 4(2,4- DB) plots was excellent at the early stage of application but required three- fourths pound per acre for control at the later stage of weed growth. Pigweed control was rather ineffective in bromoxynil plots at Logan where moisture was optimum, but effective in plots at Farmington where moisture was limited for 18-20 days following application. The density of the pigweed stand in bromoxynil treatments at Logan was attributed to an influx of weed growth following initial control of weeds. Control of pigweed by 4(2, 4- DB) was in excess of 90 percent at the four to five leaf stage of weed growth.
