Abstract

Two aphid species, Myzus persicae (Sulzer), and Aphis gossypii (Glover) and the five potato varieties (Alpha, Bintje, Berthaultii, Granola and Premiere) were used in the experiments to study the relationship between insect vector dispersal and dissemination of disease caused by potato virus Y (PVY). The results showed that M. persicae could cause time for the appearance of first symptom two to four time faster than A. gossypii . Although statistical analysis (anova) in general showed that disease incidence is not significantly different for each treatment. M. persicae caused higher disease incidence than A. gossypii on Bintje (56 and 74 days after planting). M. persicae seems to have better capability to disperse when the plant reach vegetative growth stadia which may result in higher efficiency of transmitting the virus. The relationship between aphid dispersal and dissemination of PVY can be grouped into four categories (1) plant with aphid and showing symptom; (2) plant without aphid but showing symptom; (3) plant with aphid but without symptom; (4) plant without aphid and without symptom.

Abstract

ABSTRACT: The research aims to determine the effect of PGPR application on the incidence of fusarium wilt disease and tomato plant production. The research was carried out using a Randomized Group Design (RAK) with one treatment factor, namely the PGPR dose. Treatment was made in five levels, namely D0 (control/no PGPR), D1 (5 cc PGPR/liter air), D2 (10 cc PGPR/liter air), D3 (15 cc/liter air) and D4 (20 cc PGPR/liter air air). The results of in vitro PGPR testing provided an inhibitory response to Fusarium growth with an average of 47.32% on PDA media and 63.12% on NA media. The PGPR dose treatment tested did not have a significant effect on plant height, number of leaves, production characteristics and disease intensity, except for the average number of branches per tree, root length and root weight. Giving a dose of 20 cc/liter is the best dose to increase root character and number of branches.

Abstract

ABSTRACT: Celery is an agricultural crop that has long been cultivated by indigenous Papuan people who live in the Arfak Mountains Regency because the soil structure and climate are suitable for growing celery. Currently, Arfak Mountains Regency is an area that fulfills the celery needs of Manokwari Regency so that celery plants become a source of income for local residents. One of the cultivation problems experienced by farmers is nematode disorders which cause celery to not grow to its genetic potential and even die. This is known by the presence of a kind of knot on the roots which causes abnormal growth in celery. Therefore, the aim of this research is to identify the nematodes that cause root knots and control them biologically using 2 natural control agents for Marigold plants, namely Tagetes erecta and T. patula. This plant produces yellow and red flowers and has a strong odor. The method used is a descriptive method with observation techniques. Data analysis was carried out using the Spearman Correlation test which was narrated with the help of tables and pictures. The research results showed that root knots were identified as being caused by 3 nematode species, namely Meloidogyne javanica, M. incognita, and M. arenaria. The differences between the three nematode species are known through identification of the vulva morphology found in each species. The research results also show that both Marigold species produce 2 types of secondary metabolite compounds, namely phenols and flavonoids, which function to trap and control the population and spread of nematodes. The presence of marigold plants causes celery to achieve maximum growth, number of branches and wet stover weight in suitable with its genetic potential.

Abstract

Catfish is one of the leading commodities of inland fisheries in Manokwari Regency. However, community cultivation businesses are still conventional, with minimal business capital, low human resource capacity and technological capabilities, and business management that has not run well. The purpose of this activity is to provide training and assistance on the application of appropriate technology in catfish farming as well as good and correct business management to the fish farming community in Amban Village, especially KUT PETRA. This community service will be carried out in 3 stages, namely: the preparation stage, the implementation stage and the evaluation stage. The preparation stage includes the preparation of training materials, the preparation of activity administration and the socialization of activity plans to partners. The implementation stage includes training activities, work practices and assistance for catfish farming aquaponic systems and business financial management. The evaluation stage is carried out based on the results of monitoring. The results that have been achieved from this activity are the implementation of catfish cultivation technology training activities with aquaponic systems and business financial management, and have been continued with practical work activities for making aquaponic system aquaculture media construction and business financial bookkeeping. The activity has been carried out well and partners have benefited in the form of knowledge and skills in catfish farming technology, aquaponic systems and the ability to manage business finances. The next activity that will still be carried out is business assistance and fulfillment of the outputs of this community service activity.
