Abstract

Correlation of stomata density to rust severity on some accessions of maize germplasm. Rust is an important disease on maize. Control of rust using resistant varieties is recommended because it is more practical and environmental friendly. This research aims to study on the correlation of stomata density to rust severity on the several maize germplasm accessions. The research was conducted in Bontobili Farm Experimental Station and ICERI Pathology Laboratory, held from March to August 2017; it used Randomized Block Design with 2 replicates. As much as 30 corn germplasm accessions and 2 varieties for comparison (Bima 10 and Anoman) were planted by spacing 20 x 70 cm. The inoculation of Puccinia sp. was allowed to occur naturally. Printing of stomata was conducted with painted the lower part of corn leaf with nail polish transparent. After drying, it was pasted with clear isolation and then it was pulled and saved on glass object. Observed parameters were rust severity on the age of 50, 60, 70 days after planting and density of stomata. Results of the experiment showed that disease severity of germplasm accession number 2, 218 and 243 were not significant with comparison (tolerant variety). Germplasm with accession number 234 was categorized tolerant to rust. The rust infection rate on all accession were categorized by mild to moderate. Density of stomata of each maize germplasm accession was significantly correlated with rust severity, the increase of stomata density could increase of rust severity at 0.73%.

Abstract

Incidence dynamic of pod rot disease of cocoa clones in Lampung, Indonesia. The declining of production and productivity of cocoa in Indonesia might due to pests and diseases attacks and planting unselected clones. Dynamic of pod rot incidence was important to plan pest controlling. To study dynamic incidence of some cocoa clones, a research was conducting in Pesawaran District, a centre of cocoa production in Lampung. A farmer cocoa plot under agro-forestry system was selected which had been upgrading in 2014 by pruning and side-grafting with national clones including Sul 1, MCC 1, MCC 2, ICCRI 7 and selected local clone named T1, T2, and T3. The results showed that pod rot incidence occurred along the year of observation. For immature pod, pod rot incidence was dynamic and varied among months and clones. There was high pod rot incidence every months for particular clone. National clone Sul1 and local clone T3 exhibited more tolerant to pod rot disease than other clones. Clones Sul1 and T3 also produced more pod than others. High incidence of pod rot occurred on fruit stage of cherelle (incidence 38.7%) and small pod (incidence 18.8%) that well known as cherelle wilt symptom.

Abstract

The abundance and diversity of arthropod in agro ecosystem depend on the level of synthetic pesticide contamination.  This study aimed to explore, identify and analyze the diversity and abundance of predatory arthropods in swamp rice fields treated with pesticide application (in Pemulutan) and without pesticide application (in Musi 2). The swamp rice fields in Pemulutan are bordered by village, river and forest. The methods were survey and direct observation on 3 ha and 2 ha of swamp rice fields in Pemulutan and Musi 2, Palembang. Sampling of predatory arthropods were conducted at 20, 50, 80 and 110 days after rice planting using pitfall trap.  Identification of  predatory arthropods  was conducted at Laboratory of Entomology showing that the arthropod collected consisted of 17 species of insects and 9 species of Arachnida. In Pemulutan Ogan Ilir were found 19 species (10 species of insect and 9 species of Arachnida) at the village area. In the area that was bordered by river were found 8 species (7 insect and 1 Arachnida). In the area bordered by forest were found 22 species (10 species of insects and 12 species of Arachnida). The diversity level, number of species, and arthropod specimen in the field without pesticide application at Musi 2 were higher than those in the fields with pesticide application in Pemulutan.

Abstract

Effectiveness of the application of organic matter and Trichoderma viride from suppresive soil to control fusarium wilt on banana plant. Fusarium wilt disease caused by Fusarium oxysporum f.sp. cubense is one of the problems in banana production. This research was aimed to evaluate the effect of  Trichoderma viride isolated from suppresive soil and organic matter on controlling fusarium wilt on banana plant. The efficcacy trial consisted of 12 treatments and four replications within each treatment. Each experimental unit consisted of 10 plants. Organic matters used were rice straw, cassava peel, and compost. Treatments were arranged in a randomized complete block design. Data obtained were analyzed by analysis of variance followed by orthogonal analysis (P?0.05). Application of T. viride suppressed disease incident up to 65%. The highest disease incident occurred in plants treated without T. viride and organic matter and in plants treated with organic matter only (78.33%). Disease incidence in plants treated with T.viride was lower than those treated with the combination of T. viride and organic matter. Different application times (in nursery or soil medium) did not significantly affect fusarium wilt incidence. The type of organic matter did not significantly affect the incidence and severity of fusarium wilt.

Abstract

Decrease in production and quality of grain due to neck blast disease in some lowland rice varieties. Neck blast disease of rice causes a decrease in yields both in quantity and quality. The study was conducted to see the effect of neck blast disease on the characteristics of grain and yields of several high yielding varieties of lowland rice. The varieties used were Ciherang, Inpari 4, Inpari 7, Inpari 8, and Inpari 9. The parameters observed were the incidence and severity of neck blast disease, the ratio of the size of the seeds of healthy and sick panicles and the estimated production. The analysis showed that all varieties planted were infected by neck blast disease, but based on Disease Incident rate in the Necks, Ciherang and Inpari 8 varieties reacted susceptible to neck blast disease, Inpari 7 and 9 were moderate and Inpari 4 was resistant to neck blast disease.  The quality of panicle grain infected by neck blast disease has decreased the size of grain width and was significantly different from grain of healthy panicles in all varieties. The highest estimated productivity was Inpari 4 variety of 10,378 kg/ha which experienced a decrease in production by 35.86% and the lowest was Ciherang variety of 8,367 kg/ha which experienced a decrease in production by 48.37% when they were infected by neck blast disease.

Abstract

Pod borer is a major pest on soybean. The objective of this study was to determine the resistance of soybean genotypes against pod borer based on choice test. The experiment was conducted in green house and laboratory of Entomology, Indonesian Legumes and Tuber Crops Research Institute, using Randomized Block Design with 16 soybean genotypes and three replicates. Planting dates was arranged such a way so as to sincronize the flowering time and pod formation of 16 soybean genotypes. A pairs of 4 days emerged adult pod borer were infested into each plant at R4 stage (21 days after flowering) for two days. The number of egg was observed at 2 days after infestation (DAI) and the number of larva and damaged intensity were observed at 14 DAI. The results showed that genotypes significantly affected egg and larval population, pod and seed damage intensity. The lowest egg and larval population found on Anjasmoro, 6,33 eggs and 10 individuals, respectively. The lowest intensity of pod damage found on Anjasmoro (27,74%), and the lowest intensity of seed damage found on Malabar/Sinabung-68 (15,61%). The resistance of soybean genotypes was non-preference as place to lay eggs and as feed. In conclusion, there were two genotypes showed consistently resistant (Anjasmoro and Malabar/Sinabung-68). These genotypes could be used as a source of genes for varietal improvement of soybean resistance against pod borer.

Abstract

Laboratory Evaluation of Local Isolates of Beauveria bassiana and Metarhizium anisopliae against Coffee Berry Borer, Hyphotenemus hampei, using spryaing method. Beauveria bassiana Bals (Vuillemin) and Metarhizium anisopliae (Metschnikoff) Sorokin are two species of fungi that have been studied widely and used as biological control of various insect pests, including coffee berry borer (CBB), Hyphotenemus hampei Ferrari. Laboratory studies were done in June – July 2017, to evaluate local isolates of both fungi species against CBB, the most destructive insect pest of coffee worldwide, including in Indonesia. B. bassiana was isolated from dead sweet potato weevil (Cylas formicarius) and green stink bug (Nezara viridula), and from soil. M. anisopliae was isolated from soil. The pure cultures of the fungi were mass-cultured on corn based media. The conidia harvested from 4 week colonies was hand sprayed directly upon CBB adults (females) and damaged coffee berry at the concentration of 109 ml-1. In additions, the conidia of B. bassiana isolated from C. formicarius alone was diluted to 106- 109 ml-1 and applied to damaged coffee berry. The results showed that when the conidia were applied directly upon the insects, the mortality of beetle were higher in B. bassiana than in M. anisopliae treatments. Pooled data indicated that B. bassiana isolated from death insects significantly caused higher mortality than did M. anisopliae isolated from soil. Beetle mortality was 76.7 and 80.0% for B. basiana, and 60.3 and 60% for M. anysopliae treatments. Application upon damage coffee berry indicated much lower mortality. Application of higher concentration upon damaged coffee berry resulted higher mortality, but data are not consistent. The mortality of CBB larvae was much less and negligible even at the highest conidia concentration.

Abstract

Genotypic selection on red chili palnts resistant to anthracnose disease at m2 generation. A superior anthracnose resistant cultivar was sought to overcome the low production due to anthracnose in red chili. For the development of superior cultivars, it was necessary to select genotypes that were resistant to anthracnose. Selection effectiveness was determined by wide diversity and high reliability. The purpose of this study was to see the diversity and heritability of agronomic characters and resistance to anthracnose on chili plants, and to select genotypes that were resistant to anthracnose. This research was conducted with a design without repetition. The plant material used was the seed of the results of gamma ray mutations in generation M2. The results of this study were: the broad diversity of phenotypes found in all characters observed, while all characters of the genotype observed had broad criteria except plant height at flowering and harvest, and at seedling period. The genotype that should be planted in the next generation was genotype number 136. Genotype number 136 was very resistant to anthracnose infection.

Abstract

Outbreak of oil palm bagwormPteroma pendula has been reported within the last few years in several plantations in North Sumatra. A study was conductedto determine the impact of P. pendula attacks on oil palm productivity. Aerial photograph was taken in November 2016 andanalyzed to determine the level of damage on each palm canopy. The damage symptoms were classified onto healthy palms ascontrol plants (score 0), mild (score 1), moderate (score 2), severe (score 3), and very severe (score 4). The sample palms wererandomly selected and observed for the sex ratio, bunch number and bunch weight at 18 months after defoliation. The attackof P. pendula at the highest level (score 4) caused a significant effect on sex ratio and the number of bunches produced. Thefresh fruit bunches production was declined 21.02–36.35% on palms with moderate to very severe attack (score 2–4). Similarpalms also have a potential case of inflorescences abortion 18.41–32.54%. However, the average bunch weight was notinfluenced by P. pendula attack.

Abstract

Entomopathogenic Nematodes (EpNs) that serve as biological control agents include Steinernema spp and  Heterorhabditis spp. EPNs Heterorhabditis indicus (Bromo Isolate) has a high toxicity against larvae Lepidoptera and Coleoptera and was successfully developed for mass production in Biological Control Laboratory of Jember University. These nematodes will be formulated as solid and liquid biopesticides. This research aims: to find EPNs local isolates from smallholder coffee plantations; to identify local and in vivo and in vitro cultured EPNs isolates; to determine the pathogenicity of EpNs local isolate against Coffee Berry Borrer (CBB) Hypothenemus hampei Ferr and to formulate EpNs in vitro culture as a liquid and solid formula. These formula were tested for the patogenicity and viability of EpNs to the larvae of H. hampei, Tenebrio molitor and Galleria melonella. The results showed that the pathogenecity of EpNs isolate to the larvae of CBB in Silo was 30% after 24 hours and 90% after 48 hours of in vivo inoculation. However, the mortality of CBB larvae was only 10% by liquid spraying on the coffee berry. The viability was 524 IJ (Infective Juvenile) on liquid formula packed on polyurethane sponge, and this was higher than that on solid formula (330 IJ).
