Biological Control of Banded Leaf and Sheath Blight Disease (Rhizoctonia Solani Kuhn) in Corn with Formulated Bacillus Subtilis Br23

Rhizoctonia solani Kuhn. causing banded leaf and sheath blight diseases is one of the important fungi of corn world wide. The fungus is commonly controlled by using fungicide because no resistant variety available. The objective of the study was to develop a seed treatment formulation of the selected Bacillus subtilis to control R. solani in corn. The study was conducted in the Department of Plant Pathology, College of Agriculture, University of the Philippines Los Bañòs, College, Laguna from May 2004 to August 2005, using sweet corn var. IPB Supersweet as test plant. Corn seeds were surface sterilized for 10 minutes in 1% sodium hypochlorite solution and 5% ethanol, washed thrice with sterile distilled water and air-dried. The seeds were coated with formulated B. subtilis BR23 and used for several experiments, such as evaluation for their germination and growth in the laboratory, effectively on R. solani in the baked and nonbaked field soil under greenhouse condition, and in the microplots artificially infested with R. solani. The treatment was compared with other standard seed treatment of synthetic fungicides such as captan (10 g per kg seeds) and metalaxyl (10 g per kg seeds). The experiments were designed in a completely random design with three replications. Parameters observed were seed germination, plant height, disease scores, and plant yield. Laboratory formulated B. subtilis BR23 used as seed treatment had no detrimental effects on seed germination and seedling vigor. In microplots artificially infested with a selected highly virulent R. solani, seed treatment with the same formulation increased grain yield by 27% compared to that of the control captan seed treatment with 14.4%. The studies showed the potential of B. subtilis BR23 for commercialization as a seed treatment for the control of banded leaf and sheath blight disease (R. solani) in corn

Refraining or Resisting:Responses of Green Movement Supporters to Repression During the 2013 Iranian Presidential Elections

Findings on the effect of repression on political participation are mixed and inconclusive. This article addresses this puzzle by introducing and conceptualizing ‘responses to repression’ as individuals’ varying willingness to risk-taking and continuing with political activities despite possible threats. We use three-wave panel survey data and focus on the run-up to the 2013 Iranian presidential elections, during which the gradual decline in political participation of Green Movement supporters turned into a remarkable increase in activism. The findings indicate that the decision to either refrain from or resist repression plays an important role in explaining some forms of political participation. And, in turn, this decision to either refrain or resist is influenced by social-psychological factors: Iranian Green Movement (IGM) supporters who experienced less fear, were more aggrieved and perceived lower levels of repression than other supporters, were more inclined to embrace risks. Consequently, they more frequently engaged in everyday forms of resistance – covert activities, which are difficult to be controlled and surveilled by states. It implies that social movement supporters in repressive contexts cannot only ignore the risks associated with activism and continue with the same activity but can also find or invent other forms of political activity to resist repression

De Schrift, het dogma en de dogmatiek

Scripture, dogma and dogmatics In this article it is argued that in actual systematic reflection on the Christian faith we cannot a priori assume that the dogma has the same content as Scripture, because it is strongly determined by its cultural-philosophical, its theological and its ecclesiastical-political contexts. Secondly, it is argued that the dogma is not a rule of faith or a hermeneutical rule for the interpretation of Scripture, but a grammatical rule for the use of the vocabulary of faith. Thirdly, Lindbeck’s concept of truth is discussed. Lindbeck rightly maintains a notion of ontological truth as correspondence, but wrongly reduces this correspondence to correspondence between the life of the believer and God and unnecessarily restricts ontological truth to the first order propositions of faith. Doctrinal propositions can claim ontological truth too (though they don’t need to do so). This criticism, however, does not affect Lindbeck’s clarifying analysis of the rule-character of doctrinal propositions
