Abstract

There were ten processed wastes (molase, vinase, sludge, ciu, brem, tofu, milk, cacao, fish, and beer) used in these experiments. The experiments were conducted in two separated arrangements: no choice test and choice test. The no choice test was carried by testing the attractiveness of B. carambolae on each waste was compared with water. Each run consisted of four replication, for each replication consisted of 20 females and 20 males. The choice test was conducted by placing all wastes in a cage at the same time. Each run consisted of 15 replication, for each replication consisted of 100 females dan 100 males. The no choice test results showed that B. carambolae tend to visit waste more than water. The choice test results showed that B. carambolae tend to be more frequent visits to beer and cocoa waste. The content of protein inside the waste seemed to play role in attracting B. carambolae to come with.

Abstract

The existence of seed-borne fungi could degrade the seed quality in its viability and may cause disease after planting. The aim of this research was to know the hot vapor treatment effectiveness in controlling that fungal disease and its influence to the viability of corn seed. The treatment effectiveness was measured based on the reduction of the fungal growth and sporulation on Potato DextroseAgar (PDA), the fungal infection on seed, and not reduced the seed viability significantly after treatment. Hot vapor treatment was done in 50°C, 60°C, and 70°C temperature for 20 minutes and a control. The temperature treatments cover 5 minutes of antecedent treatment in the form of appliance warm-up until the target temperature obtained, 10 minutes in the treatment drum and 5 minutes for resting time while the faucet is being shut down but the exhaust fan remain to be opened. Result of the research show that in vitro test of hot water vapor on 60oC and 70oC killed Aspergillus flavus, A. niger, Fusarium sp., and Penicillium sp. isolates. Both of the temperatures reduced the corn seed viability significantly. Infection of A. flavus still dominant in corn seed after treated on the three temperatures.The hot vapor treatment with 50oC is good for seed treatment of 408.9 g corn seed although the seed had been stored for about 9 months.

Abstract

Soil fertility can pressure rate attack of gummosis disease on cashew nut plantation in Muna Regency South-East Sulawesi. Blendok disease or gummosis have disseminated on some cashew plantation in Muna Regency, South-East Sulawesi. There was a correlation between soil fertilities and disease spreading. This assessment was intended to know the level attack and damage which were resulted from disease of gummosis at cashew crop. The assessment was conducted at Fongkaniwa Village of Muna Regency South-East of Sulawesi in 2004, using the rural cashew nut plantation in 30 ha area. The assessment area was divided into three blocks, i.e. high, moderate, and low level of soil fertility. Result of study indicated that attack intensity of gummosis disease on cashew nut are 19.49 %, 30.43 %, and 50.03 % on each levels of soil fertility, while Rate of Attack by the score value of 0.16, 1.14, and 1.77. Result of study indicated that improvement of soil fertility of cashew plantation are very important to pressure of attack and damage of gummosis disease.

Abstract

The effectiveness of a synthetic-pheromone trap with active ingredient of ethyl-4-methyloctanoate in catching adults of Oryctes rhinoceros was believed to be influenced by the trap color. A RCBD trial with single factor and three block replicates was conducted during September to October 2008 at Oil-Palm-Trial Station at PTPN III, Labuhan Batu District, North-Sumatera Province. The single factor was trap color i.e. orange, green, white, blue, red, yellow, and pink. Results showed that total numbers and sex ratios of collected O. rhinoceros adults were not significantly influenced by the trap color. The total numbers of collected O. rhinoceros adult during 30 days on color of orange, green, white, blue, red, yellow, and pink were 136, 177, 126, 155, 129, 114, and 113 individuals with sex ratios ♂/♀ 0.47, 0.52, 0.62, 0.50, 0.60, 0.49, and 0.54, respectively. The synthetic pheromone significantly attracted more O. rhinoceros female (65%) rather than the male one (35%).

Abstract

Many definitions of the suppressive soil purposed were proposed by some authors, however in summary, suppressive soil is the soil where virulent pathogen and susceptible host exist but the population and or disease produced by the pathogen are limited, due to the biotic factors supported by some specific environmental conditions. The suppressive soil phenomena has been recognized since 100 years ago, but it was thought as an interesting field since 30 years ago, and since the year many research topics related to the suppressive soil are conducted and leading to be popular. Based on the characteristic, suppressive soil could be grouped into general suppressive involving an antagonistic microbe complex being nontransferable, and specific suppressive caused by one or some antagonistic microbe being transferable. Antagonism mechanism of the microbes involved in the suppressiveness could be through antibiosis, competision, parasitism, predatism, and induced resistance.

Abstract

This research aimed to study growth ability and virulence of several Fusarium oxysporum f.sp. zingiberi isolates originated from Boyolali and Temanggung after being preserved for six years in sterile soils media. Completely Randomized Design was used with 12 treatments and 3 replications. F. oxysporum f.sp. zingiberi originated from Temanggung consisted of 7 isolates, i.e., TKO1, TKO3, TKO4, TKO6, TKO7, TPO1, TPO5; and from Boyolali consisted of 4 isolates, i.e., BAO2, BAO7, BAC, and BAP. Variables observed were growth on PDA, colony color, colony diameter, macroconidia and microconidia, mycelial dry weight, incubation period, attack area, and difference of fresh weight of rhizome. The result showed that all isolates of F. oxysporum f.sp. zingiberi both from Temanggung and Boyolali were able to grow well on PDA and fully covered the Petridish at 4.75–7.5 days. The most virulent isolate was TKO6 from Temanggung showing the fastest incubation period of 5 days after inoculation and the highest attack area of 420 mm2 or increase for 107.6%.

Abstract

This study was conducted to observe and identify viruses from infected shallots in several shallot planting center. The observation was done in eight areas of three provinces (Yogyakarta, Central Java, and East Java). Leaves from shallot plants and shallot germination showing virus symptoms were examined. The leaves were then investigated to identify viruses infecting shallots using Enzyme-Linked Immunosorbent Assay (ELISA). The result revealed that the type of virus symptoms infecting the shallots was a mozaic symptom with yellow strips. The ELISA analysis showed that Tawangmangu Biru shallot cultivar plants sampled from Blumbang, Tawangmangu (Central Java) and Philiphine Bima shallot cultivar seeds collected from Srigading, Sanden, Bantul (Yogyakarta) were positively infected by Onion Yellow Dwarf Virus (OYDV). The result also revealed that Biru, Kuning Tablet, Lokal Tawangmangu, and Bima Curut shallot cultivars had the potency to be virus resistant plants and could be considered as candidates for breeding program.
