It is applied at 0.8 to 1.1 kg/ha of active ingredient, pre -plant incorporated with a disk or vibrating shank cultivator, and then by a second incorporation at right angles to the first. Treflangives good annual grass control and some broadleaf control but misses ragweed, mustard and lady's thung. Poast is registered for post emergence control of annual grasses and volunteer cereals. Recommended rates are 0.9 to 1.9 litres/ha plus Assist oil concentrate. Applications for full registration have been submitted for three herbicides to be used with triazine-tolerant canola: • Atrazine - 0.75 kg/ha (a.i.) applied early post (two leaf stage) with oil; or pre -emer- gence applications at planting using 1 kg/ha (a.i.). ' • Bladex Liquid - 1.5 kg/ha (a.i.) applied early post (two leaf stage). No additional oil is necessary with Bladex Liquid. If Bladex powder is used, oil is necessary. • Sencor (metribuzin) - may be used alone or in a tank mix with Treflan. The rate is 0.37 kg/ha (a.i.) pre -plant incorporated. All these herbicides will control wild mustard as well as most other annual weeds. Spraying must be done early for good control. Atrazine is the least expensive and most widely used triazine herbicide. Caution! Before spraying, be sure all residues of 2, 4-D, MCPA or other phenoxy- type herbicides are thoroughly removed from the sprayer. Canola is extremely sensitive to these' herbicides. Swathing: Swath when 25 per centof the seeds in averagepods have turned from green to red or brown. Over ripe canola will shatter badly and is too fluffy to swath well. If difficulties are encountered, it helps to swath when the crop is moist with dew or a light drizzle. It also helps to use dividers. On' swathers, these are* asaall"y'" sfeeT"ro'ds (e.g. silo hoops) which curve' up abovethe crop and force the crop down where the knife cuts it off. With a divider like this, cutting the next swath in the oppposite direction helps to pick up the strip pushed down by the ,wide j Leave as much stubble as possible to atm swathing, keep the windrow off the ground, and minimize wear on the combine. Combining:, Most combine manuals include instructions for canola, A belt pickup is preferred. Combine adjustments will be 600 to 75 rpm. 2 cm (3/4") from concave clearance and 1 cm (3/8") rear concave clearance, with wind essentially closed and sieves closed. Some operators use rapeseed screens while others do not. Canola threshes easily. Avoid breadking up the. straw as much as possible. Use just enough wind to float straw and pods on the plant at a corn plant population of 23,000 -chafer while seeds are shaken out. Good combine set up will allow some pod -ends to come into the bin. A very clean sample likely means seed is being blown out the back of the combine. Be prepared to plug leaks in the combine. Moisture Contents Canola seed is sold on the basis of 10.5 per cent moisture. However, it stores well at less than 10 per cent moisture. Canola dries quickly in the swath. Unally� seven days of good drying weather will lower the moisture content into ,the proper range. Canola seed moisture can drop by one per cent or more per hour in the swath on a good drying day. Most operators start combining a$ about 13 per cent moisture. Marketing: Canola can be delivered to a number of Ontario .elevators as well as directly to two crushers. Deliveries should be pre -arranged to avoid problems. Contacts at the crushers are: Paul Glennie, Canadian Vegetable Oil Processing, Hamilton (416- 527-9121) and Ken Latta, Maple Leaf Monarch Co., Toronto (416-252-5551). Maple Leaf Monarch's crushing plant is in Windsor but arrangements for delivery are made through their Toronto office. Opportunities exist to forward sell part of next year's crops. Contact crushers' or elevators for details. Quality: A sample is taken and hand picked to determine the percentage of visibly damaged seeds. A 100 seed counter stick is repeated five times to determine green seed percentage and ten times for heat damage assessment. Dockage is assessed as the material removed when the seed is cleaned. Mustard seed, when it is less than 5 per cent of the total, is disregarded and does not affect grade, but at levels exceeding 5 per cent it will reduce the quality of the oil produced. Whiter Canola Many varieties of winter canola are now available under. contract. Winter survival has been the main obstacle to production of this crop. A 30 per cent stand which is evenly spaced will fill in to produce average yields. The yield potential is 40 - 50 per cent more _..tharn_.,sp g.,.ganPla. Apel_ it_.-as-_saghth 1:-e.ss . winter hardy than winter wheat. Loamy .or sandy 'soils are best as heaving is a problem in heavier soils. Good snow cover helps to reduce this. Planting: The optimum dates are mid -late August. This allows time to build root reserves up but not for the plant to grow too high. Seeding rates of three to four kg/ha mixed withfive kg/ha of insecticide sown through a grain drill have given the best results. Fertilizer can be broadcast to supply 30 kg/ha actual of nitrogen, phosophorus and potash. Early spring is the time to put on 100` kg/ha of actual nitrogen. This crop is very competitive so herbicides are generally not needed. Harvesting: Winter canola does not shatter as much as spring canola so it may be direct combined. As with spring canola, dividers or vertical cutter bars must be used to guide the ,plants into the combine. Swathing may also be done. Certified seed can aid in overall weed control The farmer's 'war on weeds' is a fight that truly never ends! Use of Certified seed plays an important part in keeping weed popula- tions -down. Bin run seed is bound to contain a certain level of weed seed contamination. Granted, these will be weed species that are already established in your soils. However, the weed seeds contained in a bin run sample will simply increase more competition, tougher control and a further build up of the weed population. Certified seed can make an important contribution to the overall weed control program. Canadian Seed Growers' Associa- tion (CSGA) members go to considerable length to ensure that their pedigreed product is free of weed seeds. Prior to certification, representative samples of every seed crop are submitted to Agriculture Canada laboratories. Strict government standards dictate a very rigorous testing procedure for samples of potential Certified seed. No prohibited weeds such as cleavers in rapeseed, or field bindweed in wheat - are allowed. An absolute minimum of nuisance weeds (wild oats, stinkweek, etc.) is permitted. If the sample doesn't meet these stringent criteria, it cannot be sold 'as Certified seed. Obviously, Pedigreed seed growers do everyting possible to eliminate weeds in their crops - their livelihoods depend on doing so! Comprehensive weed control programs are practised on these farms. Drills, combines and trucks are thoroughly cleaned between each field and each operation to prevent contamination. Certi- fied seed is handled with separate augers, and stored separately from other crops. From seeding through final cleaning, every, step of the production process is geared to prevention of weed seed contamination. Certification standards ensure numerous other benefits. in addition to being weed free, Certified seed guarantees high germ- ination from large kernels that provide the best in seedling vigour. Minimal disease levels also help in producing maximum yields. Growers who use bin run seed are gambling with all of their other crop produc- tion inputs. Per acre cost savings are negligible with bin run versus Certified seed.
