Aims: Piper nigrum L. (black pepper) is an economically important commodity plant in Malaysia, which generated RM 200.95 million from pepper export in the year of 2018. However, the increase in pepper production is restricted by diseases. Fusarium wilt is one of the major diseases of P. nigrum L. The objectives for this study were to isolate Fusarium spp. associated with Fusarium wilt of P. nigrum L. from selected pepper farms in the northwestern region of Sarawak and to characterize the Fusarium spp. isolated morphologically and molecularly. Methodology and results: Fusarium spp. were isolated from diseased root samples. The pathogen was grown on potato dextrose agar (PDA) under dark condition at circa (ca.) 25 °C for morphological characterisation. Molecular characterisation was done by using internal transcribed spacer (ITS). Phylogenetic tree was constructed to study the genetic relationship of the isolates. Fusarium solani, F. oxysporum, F. proliferatum were the three Fusarium species identified. There were variations in morphological characters observed between and among the species, including the colony form, margin, elevation, surface appearance and pigmentation. No distinctive morphological characteristic was specific to a location. In addition, growth rate, macroconidia sporulation rate, and microconidia sporulation rate of the isolates were not correlated. In molecular phylogeny, the three Fusarium species were separated into three distinct clades representing the three identified species. The genetic relatedness between isolates within each species was depicted in the tree. Conclusion, significance and impact of study Variations were observed among isolates in this study based on morphological and molecular characterization. This study would contribute information on the variations of Fusarium spp. associated with Fusarium wilt of P. nigrum L. from the northwestern region of Sarawak.

Aims: This study aimed to determine the antibacterial activity of Piper betle L. leaf extract against Xanthomonas oryzae pv. oryzae that causes bacterial leaf blight in rice plant. Methodology and results: The antibacterial activity of the P. betle leaf extract (100, 50, 25 and 12.25 mg/mL) with four different solvents (methanol, ethyl acetate, hexane and acetone) was evaluated using a disc diffusion assay, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. The inhibition zone of methanolic extract appeared to have the maximum diameter compared to those of other extracts, which is 32.67 mm at a concentration of 100 mg/mL, followed by 30.33 mm, 22.00 mm and 20.30 mm for the concentrations of 50 mg/mL, 25 mg/mL and 12.5 mg/mL, respectively. The MIC and MBC values of the methanolic extract were 0.625 mg/mL suggesting that the extract has a bactericidal effect on X. oryzae pv. oryzae (Xoo). The time-kill curve studies revealed that the 1× MIC (0.625 mg/mL) concentration of methanolic extract had a time and concentration-dependent killing effect on Xoo. Gas chromatography-mass spectrometry (GC-MS) analysis of methanol extract revealed the presence of eugenol acetate (29.53%), 4-allyl-1,2-diacetoxybenzene (29.51%) and 2,3-dimethyl benzoic acid (22.82%) as major compounds. Conclusion, significance and impact of study The methanolic leaf extract of P. betle was proven to have an effective inhibitory effect on Xoo and may have the potential to be used as an alternative management strategy for controlling rice diseases. In the future study, the methanolic leaf extract of P. betle is one of the recommendations to be applied in glasshouse and field trials.

OBJECTIVE: The aqueous and pelletized admixture of Piper nigrum L. was evaluated for its oviposition response and larvicidal activity against Aedes aegypti mosquitoes.

METHODS: The aqueous and pelletized extract of Piper nigrum L. was prepared and first tested in the laboratory. Efficiency is evaluated using the mosquito-chamber test. A small-scale field test was also done to determine the oviposition response of the pepper extract to ovicidal-larvicidal (OL) traps. Larvicidal bioassay following the WHO standard protocols with slight modification at different concentrations was performed.

RESULTS: Results of the mosquito chamber test in the laboratory showed that the aqueous solution exhibited an increasing rate of oviposition attraction of female Aedes aegypti to increasing rate of concentration with an average of 70% attraction at 1000 ppm as compared to 30% attraction to OL traps with water alone. The aqueous pepper-based solution and pelletized pepper solution at 1000 and 2000 ppm are considered attractants to Aedes mosquitoes. Both solutions have oviposition activity index (OAI) of > +0.3. It was also field tested on the 10 buildings within the Department of Science and Technology (DOST) compound. Results showed an oviposition ratio two times better in both the 1000 ppm concentration of the aqueous pepper-based solution and pelletized pepper solution as compared to the control. The positive ovitrap index was in the range of 78%-84% for both the aqueous pepper-based and pelletized pepper against water which is 70.0%. Larvicidal activity of the aqueous pepper-based solution against 3rd larval instars of Aedes aegypti at increasing dosages from 75mg/1 to 600 mg/I had an LCso of 127 mg/I and 395 mg/I for LC90 The LCso for the solution with pelletized pepper at the same dosing concentration is 117 mg/I with LC90 of 285 mg/1. The results also showed that these can be used to control larval instars of the Aedes aegypti mosquitoes.

CONCLUSION: The overall results indicate that the aqueous and pelletized extracts of Piper nigrum L. are effective in attracting the Aedes aegypti mosquitoes for oviposition and exhibit a larvicidal activity.
