Abstract

Citrus production in Riau have been in inadequate to meet the people's consumptionin terms ofboth quality and quantity. This presents an influx of imported fruits, including oranges in Riau. The entryof imported fruit can carry pathogens that can degrade the quality of these fruits. Research was conductedin the Laboratory of Plant Diseases of Agricultural Faculty of Riau University of from June to August2011. Purpose of this study was to identify the symptoms and causes disease in citrus fruit imports duringpost harvest in Pekanbaru. Research conducted using survey method with the determination of marketsamples are purposive sampling. Of the mind that a disease affecting citrus fruit imports in the cityPekanbaru in the supermarket is Anthracnose disease caused by Colletotrichum sp, Aspergillus rot causedby Aspergillus sp, Fusarium rot caused by Fusarium sp and Alternaria fruit rot caused by Alternaria sp.In traditional markets is a disease and rot Anthracnose disease Aspergillus.

Abstract

Objective of this research was to test the ability of Trickottermasp isolate andget the best isolate incontrolling blighted leave disease on dendrobium orchid. TUs research was conducted cxperimentelly usingCompletely Randondzed Design (RAL) byfivetreatments of TridHHlerma sp isoUte (TO « without TrichuJennmsp,TI 'isotateT-ag,T2-=T-«a,T3>T-k,T4'^b). Resultof research indicates that application of some isolateon dendrobium orchid gives different influence hi controlling blighted leave disease on orchid. In controllingPhytopktkon sp.. Isolate T-ag is better because it has stronger hihibition ability.

Abstract

The research aims to observe and obtain a better concentration of powder extract citronella grass leaf tocontrol anthracnose disease on red chili fruits. The research has been conducted experimentally using acompletely randomized design, consisted of 6 treatments and 4 replications thus obtained 24 trial units. Theresearch consisted of two phases: in vitro inhibition of C. capsici and in vivo application of powder extractcitronella grass leaf on red chili fruits. The concentration of powder extract citronella grass leaf used are:S0= 0 g/l, S1= 50 g/l, S2= 100 g/l, S3= 150 g/l, S4= 200 g/l dan S5= 250 g/l of water. The data werestatistically analyzed using analysis of variance and the means were tested with Duncan ‘s New MultipleRange Test (DNMRT) at level of 5%. The results of the research showed that the concentration of powderextract citronella grass leaf at 200 g/l of water tended to show a better ability to inhibit the growth of C.capsici at in vitro phase with growth inhibition up to 22,26%.Key words: Red chili, C. capsici and Cymbopogon nardus L.

Abstract

losses on cocoa is black pod disease (BPD) caused by Phytophthora palmivora Butl. Alternatif control of thedisease is using biocontrol agent such as Trichoderma harzianum Rifai formulated in a powder biofungicidewhich has to be applied in a right concentration. The research aims to observe the effect of biofungicidepowder of T. harzianum in some concentrations and obtain the best consentration to control P. palmivoracauses cocoa black pod disease. This research has been conducted at Plant Pathology Laboratory, AgricultureFaculty of Riau University from August to October 2015. The research was carried out experimentally usinga completely randomized design consisted of 7 treatments (0, 100, 200, 300, 400, 500 and 600 g/l) and 4replications. The research consisted of two phases: in vitro inhibition test to P. palmivora and in vivoapplication test of T. harzianum powder biofungicide. Data obtained were statistically analyzed usinganalysis of variance and continued with Duncan’s New Multiple Range Test (DNMRT) at 5% level. Theresults showed that the concentration of T. harzianum powder biofungicide at 500 g/l had a better ability toinhibit the growth of P. palmivora at in vitro test with an inhibition up to 45,00% and relatively able tocontrol P. palmivora causes cocoa black pod disease at in vivo test with disease intensity 31,25%.

Abstract

A research has been conducted to study the effect of some concentrations of Noni (Morindacitrifolia L.) fruit extract in controlling anthracnose disease, caused by Colletorichum capsici on thepost-harvested red chilli fruits. The research has been conducted experimentally using a CompletelyRandomized Design consisting of 5 treatments and 4 replications. The treatments are someconcentrations of noni fruit extract : 0%=Mo, 5%=M1,10%=M2,15%=M3 and 20%=M4. Result of theresearch indicated that the concentration of noni fruit extract gave a significantly different effect incontrolling anthracnose disease on post-harvested red chilli fruits. The concentration of noni fruit extractat 20% showed a better effect in controlling anthracnose disease on post-harvested red chilli fruits whichresulted in a smaller in-vitro colony growth of the causal fungal pathogen, a longer incubation period ofthe disease and a lower disease intensity.

Abstract

The objective of this research is to study the effect of some concentrations of neem leaves extractin controlling anthracnose disease on post-harvested red chilli fruits. A research has been conductedexperimentally using a Completely Randomized Design, consisting of 6 treatments and 5 replications. Thetreatments are 6 concentrations of neem leaves extract : 0%=M0, 1%=M1, 5%=M2, 10%=M3, 15%= M4and 20%=M. Result of the research indicated that the concentration of neem leaves extract gave differenteffect in controlling anthracnose disease of the red chilli fruits. The concentration of neem leaves extractat 15% and 20% gave a better effect in controlling anthracnose disease of post-harvested red chilli fruits,which resulted in a smaller diameter of in-vitro fungi colony growth, a longer incubation period of thedisease and a lower incidence of the disease.
