Manitoba Update
August 15, 2012
According to this week's crop report from Manitoba Agriculture, Food and Rural Initiatives, as of Monday, edible beans were 7 to 10 days away from cutting in Manitoba. Beans in the southern part of the province around Winkler and Altona have started to yellow off due to the dry conditons with some of the earliest fields potentially being cut by the end of this week. The hot, dry conditions have resulted in some flower and pod abortion which will affect yield. Growers considering using pre-harvest glyphosate to control weeds should consider the following. Some countries that Canada exports beans to have limits on the maximum residue levels allowed for products such as glyphosate. If you spray too early the residue level could be higher than what is allowed, so proper staging is important. The stems should be green to brown in color and pods mature and with 80-90 percent leaf drop. Producers should also check with the companies they sell their beans to, to verify any restrictions that they may have when using glyphosate.
