Abstract

The obstacle in improving production of soybean is the attack of Cowpea mildmottle virus (CMMV). CMMV infection in the field by vector insect Bemisiatabaci. Entomopathogen fungi Lecanicillium lecanii is effective in killing insectsfrom homoptera ordo particularly Bemisia tabaci. Result of this study reveal thatthe higher conidia density in fungi L. lecanii, the more pathogenic this fungi inkilling B. tabaci thus CMMV intensity contaminated by vector insects is lower.Death of tested insects infected by fungi L. lecanii was highlighted with whitecolor mycelium colony that covers insect body. Conidia density of fungi L. lecaniiis effective in killing B. tabaci 108/ml with mortality rate 68.5% so that reduceCMMV attack intensity. The faster incubation period of fungi L. lecanii towardinsect would result lower ability of B. tabaci in spreading CMMV until reaching3.43%. The large seed soybean (Argomulyo) has trichoma density 127.18/cm2which is more vulnerable to be infected with CMMV compared with small seedsoybean (Wilis) which has trichoma density 182.83/cm2. Attack intensity ofCMMV in Argomulyo variety is reaching 29.89% while attack intensity in Wilisvariety only reach 23.94%. Reviewed from the efficacy of the fungi L. lecanii inkilling B. tabaci, the results of this study can be concluded 108/ml conidial densityis an effective dose. The use of small seed soybean varieties (Willis) with adensity of more tightly trichoma can pressess B. tabaci’s attack and CMMVinfection on soybean plants.Keywords: B. tabaci, Conidia density of L.

Abstract

One of the main disease of chili cultivation is mosaic disease that is caused byTMV (Tobacco Mosaic Virus). One effort to control the disease could be done byapplying Plant Growth Promoting Rhizobacteria (PGPR). PGPR is a usefulbacteria that lives and grows well in soil that contain much of organic matter. Thisresearch aimed to determine the effect of application and the role of PGPRPseudomonas fluorescens, Azotobacter sp., dan Bacillus subtilis on TMV attackintensity, the height and production of chili plant. This research was conducted inscreen house and plant disease laboratory, Brawijaya University Malang. Theexperiment started in April until August 2012. This research was using completerandomized design. The treatments used one species of PGPR bacteria and thecombination of two species of PGPR bacteria. The PGPR were PGPR P.fluorescens, PGPR Azotobacter sp., or PGPR B. subtilis. Whereas the PGPRcombination were PGPR P. fluorescens and PGPR Azotobacter sp., PGPR P.fluorescens and PGPR B. subtilis, or PGPR Azotobacter sp. and PGPR B. subtilis.Control were executed without applying PGPR. Results showed that thecombination of P. fluorescens and Azotobacter sp. PGPR affected on reducing theincubation periode, the attack intensity of TMV, and increasing the plant height.The incubation periode for chili plants with PGPR P. fluorescens and Azotobactersp. was 16,67 days. The PGPR P. fluorescens and Azotobacter sp. reduced TMVattack intensity on chili plants until 89,92%. The plant height of chili plants withPGPR P. fluorescens and Azotobacter sp. could reach 69,25 cm. PGPR P.fluorescens dan B. subtilis treatment could increase the average fruit weight ofchili until 2,17 grams per plant.Keywords: PGPR, Pseudomonas fluorescens, Azotobacter sp., Bacillus subtilis,TMV, chili

Abstract

Diseases caused by TMV (Tobacco Mosaic Virus) on chili is important to notebecause it can cause a loss. Chili varieties are currently circulating in the marketand have not been evaluated resistance to TMV (Tobacco Mosaic Virus).Therefore, research is needed on the effects of the attack TMV (Tobacco MosaicVirus) on the growth, production and resistance to chili varieties such. The initialsymptoms are the same, namely the emergence of a mosaic on the leaves of youngplants, followed by chlorosis due to reduced chlorophyll content of plants forphotosynthesis disturbed then a widespread and causes the leaves begin to showsymptoms of the malformation. Leaves of the plant having malformations (leavesshriveled). The results showed that TMV infection can suppress plant growth anddecrease crop production. Treatment plant inoculation at different ages apparentlysignificant effect on plant growth as well as production plants. Chili plantsinfected with virus at a very young age the rate of plant growth and developmentis inhibited, so the plants will grow abnormally. Based on the parameters used tocalculate the resistance category chili tested against TMV virus showed that thevarieties are very susceptible Sonar and Bara, Cakra susceptible, moderatelyresistant while TM Rawit, Samaru resistant to TMV infection.Keywords: Chili plants, TMV, inoculation, infection and resistance

Abstract

Potato (Solanum tuberosum L.) is one of the commodities of potential as a sourceof carbohydrates and important on Indonesia's economy. One of the constraints ofpotato production is soft rot disease caused by Erwinia carotovora (syn.Pectobacterium carotovorum) which is needed to be controlled. One alternativecontrol measures is the used of bacteria Bacillus subtilis and Pseudomonasfluorescens for biological control. The purpose of this research is to know thepotential of B. subtilis and P. fluorescens in single and in combination to inhibitpotato soft rot diseases caused by E. carotovora. The results showed thatbiological control agents B. subtilis and P. fluorescens in single or in combinationboth of them (T3 to T17) have potential in inhibiting the growth of pathogenic E.carotovora by showing the clear zone. Biological agents provides nearly the sameeffect if compared with the bactericide Agrept (T2). Based on the results of thestatistical analysis, the treatment 11th and treatment 14th showed a clear zonewider than the Agrept treatment (T2). The treatment 11th contain combination ofbiological agents B. subtilis (109 cfu/ml) and P. fluorescens (105cfu/ml), while the treatment 14th contain combination of biological agents B.subtilis (107 cfu/ml) and P. fluorescens (105 cfu/ml).Keywords: Erwinia carotovora, Bacillus subtilis and Pseudomonas fluorescens
