“…Persoalan yang dihadapi oleh petani dalam budidaya cabai merah antara lain banyaknya serangan hama misalnya kutu kebul (Sangaribuan et al,, 2017), trips (Warnas, 2020) dan penyakit seperti Antaknosa (Suwastini et al, 2020), serta virus kuning (Gunaeni et al, 2015). Upaya penanggulangan kendala dalam budidaya cabai merah telh dilakukan, misalnya dengan pembuatan bibit unggul (Kirana.…”

Grafting with cayenne pepper rootstock (Capsicum frutescens L.) and red chili scion (Capsicum annum L) can be used to improve the quality of red chili plants. This study aims to determine the growth and development of red chili plants from shoot grafting. The study was carried out with 3 treatments, namely kontrol (without grafting) (Mo), treatment 1 (X1) fighting with scion from the main stem and treatment 2 (X2) grafting with scion from stem branches. Each treatment was repeated 5 times. The results showed that the highest number of leaves was obtained in the kontrol treatment, the highest number of flowers and fruits in the X2 treatment. It was concluded that shoot grafting in red chili with entries from the first branch resulted in plants with the best growth and development. From the results of this study shoot grafting can be used as a way of cultivating red chiliKeywords: Capsicum annum L.; Grafting, Growth and Development.

“…Salicylic acid is important in the plant defense mechanism against pathogen. It was reported in some studies that salicylic acid had the roles in increasing the plant resistance to virus infection (Taufik et al, 2010;Faizah et al, 2012;Gunaeni et al, 2015). Accumulation of salicylic acid is a fast reaction of plant to defense against virus infection by mobilization of secondary metabolites (Faizah et al, 2012).…”

Yellow leaf curl is a major disease on chili plants. The use of antagonistic yeasts as the control agents is a good alternative in an environmentally friendly control method. This study was objected to evaluate the potencies of Rhodotorula minuta and Candida tropicalis to promote induced resistance on chili plants against yellow leaf curl disease. The experiment was arranged in the randomized complete block design with 9 treatments and 3 replications. The treatments were the application of the yeasts at three different times of virus inoculation, as follows: A. R. minuta, virus inoculation at 3 days after transplanting (dat), B. R. minuta, virus inoculation at 7 dat, C. R. minuta, virus inoculation at 10 dat, D. C. tropicalis, virus inoculation at 3 dat, E. C. tropicalis, virus inoculation at 7 dat, F. C. tropicalis, virus inoculation at 10 dat, G. control, virus inoculation at 3 dat, H. control, virus inoculation at 7 dat, and I. control, virus inoculation at 10 dat. No treatment was applied to the control. The yeasts were applied by soaking the chili seeds, and pouring the suspension into the growth media at transplanting. The variables observed were incubation period, disease severity, and disease incidence. Peroxidase activity, phenylalanine ammonia lyase activity, and salicylic acid accumulation were also analyzed. The results showed that the application of R. minuta or C. tropicalis was able to extend the disease incubation period, but did not reduce the yellow leaf curl disease incidence and severity. The treatment of R. minuta, virus inoculation at 7 dat, increased the peroxidase activity from 2590.80 units to 6870.93 units (0.5 minute) and from 577.367 units to 1131.300 units (2.5 minutes), PAL activity from 16.059 to 17.911 A290/mg, and accumulation of salicylic acid from 2.785 to 6.263 ppm. Application of C. tropicalis, virus inoculation at 7 dat, increased the peroxidase activity from 2590.80 units to 6033.067 units (0.5 minute) and from 577.367 units to 950.967 units (2.5 minutes), and accumulation of salicylic acid from 2.785 to 6.982 ppm.

RIP (Ribosome Inactivating Protein) produced by plants that can act as a plant defense from pest and disease. This protein is widely used as an anti-fungal, anti-bacterial, anti-virus and anti-insect. Therefore, RIP contained in plants has the potential to be used for environmentally friendly biopesticides. The purpose of this paper is to provide information on RIP derived from plants and its potential as a biopesticide.The mode of action of RIP works is by inhibiting protein synthesis during translating process of pest and plant pathogen. RIP has a broad spectrum so that it can overcome insect pests from various orders and pathogens both fungi, bacteria and viruses. Some types of plants that contain RIP include neem, ginger, turmeric, galangal, castor bean, jatropha, soursop and bitter melon. RP applications can be in the form of oil, essential oils, solutions, flour, ash and simplicia. RIP can be applied to seeds, seeds, plants and post-harvest products. The advantages of using RIP include easily available materials, inexpensive, easy to application and environmentally friendly.The plants contain RP has high potency to commercially developed so in the future, the controlling of pest and disease rely on the plants contain RIP both direct and in the pesticides formulations form. Therefore echo friendly plantation programme can be realized.
