There is limited information on the sensitivity of dry bean to dimethenamid-p, saflufenacil and a preformulated mixture of dimethenamid-p/saflufenacil. Field trials were conducted at Exeter and Ridgetown, ON, Canada in 2012 and 2013 to evaluate the tolerance of four market classes of dry bean to dimethenamid-p, saflufenacil and dimethenamid-p/saflufenacil applied preemergence (PRE) at the 1X and 2X manufacturer’s recommended rate in soybean. Dimethenamid-p, saflufenacil and dimethenamid-p/saflufenacil applied PRE caused 0% - 2%, 20% - 31% and 34% - 45% injury in dry bean, respectively. Dimethenamid-p (220 and 440 g ai ha-1) caused no adverse effect on plant stand, shoot dry weight, height and yield of black, white, adzuki and kidney bean. Saflufenacil (25 and 50 g ai ha-1) or dimethenamid-p/saflufenacil (245 and 490 g ai ha-1) reduced plant stand 53% - 70%, shoot dry weight 61% - 81%, height 26% - 48% and yield 40% - 61% of black and white bean. However, saflufenacil applied alone or in combination with dimethenamid-p at the 1X or 2X rates caused no adverse effect on plant stand, shoot dry weight, height and yield of adzuki and kidney bean except with dimethenamid-p/saflufenacil at the 2X rate which reduced plant stand 38% in kidney bean, shoot dry weight 46% in adzuki bean and 42% in kidney bean, and yield 29% in kidney bean. Based on these results, saflufenacil and dimethenamid-p/saflufenacil applied PRE at the proposed rate of 25 and 245 g ai ha-1, respectively does have an adequate margin of crop safety for weed management in black and white bean. Further research is needed to ascertain the margin of crop safety in kidney and adzuki bean.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
