Abstract

[FRUIT QUALITIES OF CALAMANSI UNDER DIFFERENT SCAB DISEASE SEVERITIES]. Citrus scab caused by Elsinoë fawcettii dan Elsinoë australis fungi is an important disease for calamansi lime. The pathogen can result creamy-yellowish, raised, rounded, corky scabs appear on the rind surface of the fruit that reduces marketabilityof the fruit. The objective of this  study was to evaluate the development and intensity of scab and their effects on the physical and chemical qualities of calamansi fruits. The observations were made on 30 fruit samples collected from farmer’s calamansi orchard for the development and intensity of disease symptoms, fruit appearances, juice content, and total soluble solids of the juice. The results showed that the pathogen began to attack on early fruit set phase. The intensity of the disease at the beginning of the observation was 11.06% and increased to 58.18% with an average rate of attack intensity of 14.54%. The disease reduced the fruit weight, fruit diameter, juice volume and total soluble solid levels.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 233-241.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Dissemination of integrated pest control program (IPM) technology with biological agents needs to be carried out so that farmers are willing to adopt it. One of the determinants of adoption is farmer's perception about nature of innovation technology. This study aims to identify farmers' perceptions about IPM technology with biological agents. The research was carried out in Semarang Urban Village Bengkulu City in May-July 2021 involving 32 farmers. The location was determined purposively because it is the location for biological IPM displays. The biological agents used were consortium of bacteria Paenibacillus polymixa, Pseudomonas flourescense, and Bacillus subtilis for disease control and  consortium of fungi Metharihizium sp and Beuveria sp for pest control. The data measured is the farmer's perception of the nature of innovation technology using Likert scale and analyzed with quantitative descriptive method. Data were collected by conducting interviews using a questionnaire. The results showed that farmers assessed IPM technology with biological agents are accordance with cultural values, provides benefits, is easy to observe but is quite complicated to apply and try out.
