Abstract

The objective of the research was to determine the effect of rice straw composting by various Trichoderma spp as starter on rice seedling growth and to control stem rot and blast disease in rice . Experimental study was conducted using completely randomized design with 5 treatments and 3 replications. The treatments were application of trichocompost is           T0= Without trichocompost, T1=trichocompost pseudokoningii, T2=trichocompost harzianum, T3=trichocompost koningii, and T4= trichocompost viride.  The results showed that utilization of trichocompost did not effect soil emergence of rice seed, but resulted better rice plant growth increased growth plant rice as indicated by teller plant height, greater plant dry weight and number of tilllers of rice. Trichocompost pseudokoningii and trichocompost harzianum  performed better control to the diseases than trichocompost coningii and trichocompos viride as indicated by decreasing the intesity of both disease attacks. Keywords: Trichoderma spp., rice straw trichocompost, Rhizoctonia solani,           Pyricularia oryzae.

Abstract

The objective of the research is to study the effect of carrier materials on various drying temperatures of biofungicide granule T. pseudokoningii Rifai on               G. boninense Pat. in vitro. The research has been conducted at Plant Disease Laboratory of Agricultural Faculty and Nanotechnology and Material Laboratory of Department of Physics, Mathematics and Science Faculty, University of Riau from May 2013 to August 2013. This research has been conducted experimentally using split plot design arranged in a completely randomized design, consisted of 9 combined treatments and each treatment is repeated 3 times. Main plot is drying temperatures of biofungicide granule (T), consisted of 3 levels : T1 = 350C, T2 = 550C, T3 = 750C. Sub-plot is carrier materials of biofungicide granule (P), consisted of 3 levels : P1 = Kaolin, P2 = Zeolite, P3 = Kaolin + Zeolite. The data were statistically analyzed using analysis of variance and further analyzed with Duncan's New Multiple Range Test (DNMRT) at level 5%. The results of the research showed that kaolin, zeolite and combination of kaolin and zeolite containing in biofungicide granule of T. pseudokoningii on drying temperature of 550C gave a better result to press the growth of G. boninense, because                            T. pseudokoningii has faster growth rate, that is 3.01 mm/day.   Keywords: Biofungicide granule Trichoderma pseudokoningii, carrier materials, drying temperatures, Ganoderma boninense.

Abstract

Ganoderma boninense Pat. is one of the pathogens that infects young, immature and mature palm oil plants. Theinfection of the fungus can cause the death of palm oil plants, causing a decrease in the production of the plants.Alternative control of the disease is biological control using granular biofungicide containing Trichoderma harzianum.One factor that determines the success of the biofungicide is the dosage used. This study aims to determine the effect ofvarious dosages of T. harzianum granular biofungicide to control G. boninense and to study its effect on the growth ofyoung palm oil plants at pre nursery stage and obtain the best dosage in controlling G. boninense and to increasegrowth of young palm oil plants. This study was performed experimentally using completely randomized design consistingof 5 treatments and 4 replications. Each replication consisted of 2 young palm oil plants in medium of 4 kg soil/polybag.The treatment is dosage of granular biofungicide T. harzianum: 0, 5, 10, 15 and 20 g/polybag. The data were analyzedstatistically using analysis of variance and the means of treatment were tested with Duncan’s New Multiple Range Test(DNMRT) at level 5%. The results showed that dosage of granular biofungicide was significantly affected to control theG. boninense and to increase the height of the young plants and the volume of root of the young plant in the pre nurserystage. Dosage of granular biofungicide 10 g/polybag gave a better control to G. boninense (lowest diseases intensity:15,63 %) and to increase growth of young of palm oil plants than other dosages.

Abstract

The objective of this research was to identify the fungi at pineapple rizoshere and indication of its antagonism to Thielaviopsis paradoxa. It was conducted at laboratory from April to Juli 2006 and sampling method was purposive sampling. The parameters of this research were identification of the rizophere fungi and the ability of rizophere fungi ti inhibit the growth of Thielaviopsis paradoxa. The reasult of this research can be summarized that the pineapple rizosphere fungi identified were: 1). Bispora Sp, 2). Trichocladium Sp, 3). Trichoderma harzianicum, 4). Trichoderma longibrachiatum. Bispora Sp. and Trichocladium Sp. Do not have the ability to inhibit the growth of Thielaviopsis paradoxa, while Trichoderma harzianicum and Trichoderma longibrachiatum have the ability y to inhibit the growth of Thielaviopsis paradoxa.
