[Method] Field efficacy of six kinds of fungi- cides with 18 concentrations against apple powdery mildew was investigated. [Re- sult] 4 000-fold triflumizole WP exhibited the highest control efficacy of 82.96%, fol- lowed by 3 000-fold triflumizole WP with control efficacy of 77.75%, while 800-fold and 1 000-fold 70% thiophanate methyl WP exhibited relatively low control efficacy, which was both lower than 60%. [Conclusion] In actual production, 4 000-fold triflu- mizole WP and 3 000-fold triflumizole WP should be used alternately to control and prevent apple powdery mildew.展开更多
A study was conducted for the development of value added dahi by incorporating fruit pulps, cereal flour and whey proteins concentrate （WHC） to increase the nutritional and sensory quality. Value added dahi （VAD） ...A study was conducted for the development of value added dahi by incorporating fruit pulps, cereal flour and whey proteins concentrate （WHC） to increase the nutritional and sensory quality. Value added dahi （VAD） was prepared by using skim milk, oat flour and WPC. VAD with 1% oat flour, 1% whey protein concentrate was found to be highly acceptable by sensory evaluation and curd tension study. Statistically there was a highly significant difference （P 〈 0.05） between skim milk dahi （control） and VAD VAD scored highest sensory score for all the sensory parameters studied. Curd tension found to be markedly increased in value added dahi with increased firmness of the product. Value added stirred dahi was prepared with oat flour, whey protein concentrate, papaya, fig pulps and sugar with different combination in order to assess the suitable level of addition with maximum acceptability. Value added stirred dahi （VADl） with 1% oat flour, 1% WPC, 5% papaya pulp, 4% sugar combination was found to be acceptable among the other combinations. Storage studies evaluated by sensory score revealed that the value added dahi can be stored up to 7 days at 5 ^（2. A significant increase in acidity and decrease in pH were noticed in the VAD1 during the storage period but within the permissible limit. Statistical analysis revealed no significance difference （P 〉 0.05） in total count and yeast and mould count between VAD0 （control） and VADl during storage 5 ~C. Total yield of value added dahi increased along with cost of production due to increased cost of ingredients （fruits and whey protein concentrate） used for value addition.展开更多
