Auxinic herbicides (e.g. dicamba) are extensively used in agriculture to selectively control broadleaf weeds. Although cultivated species of Brassicaceae (e.g. Canola) are susceptible to auxinic herbicides, some biotypes of Sinapis arvensis (wild mustard) were found dicamba resistant in Canada. In this research, dicamba tolerance from wild mustard was introgressed into canola through embryo res...

in order to determine the effect of vernalization on phenology and development rate of canola varieties, an experiment was conducted at research farm of gorgan university of agricultural science and natural resources during 2005-2006. the experiment was a randomized complete block design arranged in split plot with four replications. six varieties of canola (option500, rgs003, hyola308, hyola60...

Much previous research in pest management in canola has focused on developing strategies for reducing infestation levels of single pest species (e.g., bertha armyworm), or individual pest groups (e.g., insects) without regard to possible detrimental effects of these control strategies on other pests. The aim of our research has been to integrate insect management strategies with agronomic pract...

Transgenic glyphosate-resistant canola was first commercially grown in Western Australia (WA) in 2010, providing an opportunity to obtain important baseline data regarding the level of glyphosate resistance in weeds following the exclusive use of glyphosate for in-crop weed control. In this study, two surveys (2010 and 2011) were conducted across the 14Mha of the grainbelt of WA. The 2010 surve...

We assessed the effects of cultivating two genetically modified (GM) glyphosate-tolerant soybean varieties (Glycine max (L.) Merr.) derived from Event 40-3-2 and a Japanese conventional variety on arthropods under field conditions, with weed control using glyphosate and conventional weed control for two years. Plant height and dry weight of the conventional variety were significantly larger tha...

Rubber tree production is reduced by weeds that compete for environmental resources; therefore, the timing and duration of weed control influences weed interference. The objectives of this study were to evaluate the growth of rubber tree (Hevea brasiliensis) plants, to determine the critical period for weed control, and to evaluate the growth recovery of rubber trees that coexisted with weeds f...

Present study investigated the effects of dietary increasing levels of solventextracted canola meal (CM) as a substitute for soybean meal as an energy and amino acid source in finishing pigs. A total of 192 finishing pigs (Landrace × Yorkshire × Duroc; initial body weight of 48.62 ± 3 kg) were randomly allotted to 4 treatments on the basis of BW. There were 4 replicate pens in each treatment wi...

in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...

Unsuitable planting and weed competition are the most important factors that greatly reduce the yield of bean. In order to study the effect of planting date on yield and yield components of three white bean cultivars in weed infest and weed free condition a factorial experiment with randomized complete block design and three replications was carried out at Semirom in 2009. The treatments were p...
