Blackleg and its management has become an important issue for canola in the coming seasons... As most of the canola cultivars, irrespective of the level of their adult plant resistance, are susceptible to infection by the fungus at the seedling stage (may be termed as 'seedling susceptibility window') and consequent canker formation the timing of ascospore release in relation to the onset of adult plant resistance provides information on the risk of blackleg... The risk of blackleg appears to be both location and season specific...

Early work on canola focused on weed management strategies including the breeding of herbicide tolerant canola varieties such as triazine tolerant (TT) varieties which now account for an estimated 90% of canola grown in WA... Research is still being conducted to determine the effect of these viruses on the yield of canola in WA. European work has found seed yield losses of 10-15% associated with this virus disease in canola... The amount of air passed through the grain is measured in litres per second per tonne and varies depending on the particular aeration strategy...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, yields were generally greater for those plots with effective control of weeds and lower weed biomass at anthesis (Tables 1 and 2)... In summary, metribuzin shows some promise for use pre-emergent in lupins but is not currently registered at this timing...

Sowing method (knife points or discs) did not affect performance of pre-seeding herbicides... Project No.: DAW 0134 Paper reviewed by: John Holmes Crop Updates is a partnership between the Department of Agriculture and Food, Western Australia and the Grains Research & Development Corporation 241.. Overall, the correlation coefficient between the observed ED 99dosages and the dosages predicted using Model A was 0.60 with p < 0.06...

The paper will describe this phenomenon and the implications of accelerated triazine degradation on the efficacy of this class of herbicides... Early research on the degradation of atrazine in the field indicated that the herbicide is primarily degraded by a combination of microbial and chemical hydrolysis, both of which occur very slowly... We compared the movement of atrazine in the top 30 cm of the soil profile in a plot that had accelerated degradation with an adjoining plot without the accelerated degradation...

" Improved weed control in lupins with new old products Peter Newman, Department of Agriculture and Food, Geraldton uses of KEYMESSAGES The quest to find a new, novel herbicide for wild radish control in lupins has so far failed to deliver... Metribuzin applied pre-sowing of lupin was again safe on the crop and provided very useful suppression of wild radish and doublegee... Previous research has demonstrated variable suppression of weeds depending on soil moisture and in some cases the very high rates of metribuzin pre-sowing have reduced yield (Newman Crop Updates 2011)...
