In total, detailed dose response experiments were conducted on 25 populations of annual ryegrass that were suspected of being resistant to glyphosate... Dose response experiments examining populations with different resistance mechanisms showed that the target site mutation in SLR 77 resulted in a population that is less resistant to glyphosate compared with populations containing the reduced translocation mechanism, such as NLR 70... Using a knockdown rotation of the double knock in one year and glyphosate alone in the next year is predicted to result in glyphosate resistance occurring af...

KEYMESSAGES Serradella and biserrula can substantially improve farm profit in mixed farming systems of the wheat belt by improving stocking rate, reducing supplementary feed or increasing the area of cereal at the expense of pulses and oilseeds... The aim of the paper is to discuss the economic benefits of these new species for WA farmers in the medium and low-rainfall wheat belt... Table 4: Increase in farm profit, pasture area and stocking rate resulting from the introduction of yellow serradella and biserrula on individual LMUs and a combination of LMUs...

Preliminary results indicate that strategic crop phases of legumes (lupins or vetch) or pasture with Clearfield wheat can significantly reduce brome seed-banks... Use of Sulfonly Urea herbicide Atlantis or tank mixes of Trifluralin & Logran in wheat resulted in poor control of brome grass and caused the seed-bank to rise substantially (2.35 & 2.99 fold)... Indicative of the poor herbicide options available for the control of brome in wheat, this crop type caused a 2.67 fold increase in the brome grass seed-bank...

Wild relatives of chickpea among the genus Cicer have many valuable agronomic traits crucial for improvement of the cultivar... Methods developed for wide crosses with C. pinnatifidum at ICRISAT, India (Mallikarjuna, 1999) were transferred and adapted for crosses between local chickpea cultivars, in Canada and Australia, and C. pinnatifidum... Embryo rescue has good potential as the key to unlocking the treasure chest of distant wild relatives for chickpea improvement...

Frequency distributions for carbon isotope discrimination ( ) means measured on random doubled-haploid lines from the Cranbrook/Halberd, Sunco/Tasman, and CD87/Katepwa mapping populations... Estimated additive (a) genetic effect, percent additive genetic variance, and chromosomal location (and corresponding 95% confidence intervals in parenthesis) of QTL for carbon isotope discrimination measured on random doubled-haploid progenies from the Cranbrook/Halberd, Sunco/Tasman, and CD87/Katepwa populations evaluated across two to three irrigated environments... Genotype and genotype environment...

Aim: Randomly survey paddocks in key agricultural regions for ryegrass and determine the resistance status of the region to the pre-emergent herbicide trifluralin #. , the resistance status to post-emergence herbicides was also tested... The work has shown that further field trial work should be conducted to further assess the performance of KIH-485... 0 2000 Dual Gold (ml/ha) 0 2000 Dual Gold (ml/ha) New WP250 Formulation A new WP250 formulation was developed by the same chemical company and seed-treated on wheat and barley...

pH measurements taken from wet and dry soils can vary if we measure the pH in water because the soil has a "background" salt concentration... To minimise the effect of salt concentration in soil on pH values, pH is now measured in 0.01 molar calcium chloride... As soil testing for phosphorus was originally conducted on the top 10 cm of soil, so the soil pH was only measured for the top 10 cm...

An eight-year weed management study being carried out at Northbourne, Western Australia, now in its seventhyear,provides clear evidencethat a significant reduction in in-crop ryegrassnumbers canbe achievedby taking time to run down &e seedbank... The reward for the investment is an extended period of time in crop with the addedbenefit that grass-selectiveherbicides need no longer be used - unless they are required for other grass weeds such as wild oats... Where 2*3 years of seed set control were carried out, it exhausted the seedbank to such an extent that a sustained period of cropping r...
