This study was conducted to determine the antibacterial effect of crude extracts of Annona muricata, comparing the leaf and stem bark extracts using the same extraction solvents. The bacteria isolates were obtained from the hospital. The isolates obtained are Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus mirabilis and Streptococcus pyogene; they were confirmed using standard techniques. Multiple antibiotic-resistant was confirmed in the isolates after antibiotic susceptibility testing. Extracts were prepared from the leaf and stem of A. muricata using ethanol, chloroform, cold water and hot water. The antibacterial activities of the crude extracts were assayed using the agar well diffusion method. The phytochemical screening revealed the presence of saponins, Tannins and flavonoid especially in the ethanol extracts of both leaf and stem part of the plant. All the extract showed varying degrees of antibacterial activities. Chloroform and Hot water rated best for antibacterial activities in this study. A. muricata stem hot water extract has zones of inhibition that ranges from 16.003 ± 0.009 mm to 1.000± 0.006 mm. A. muricata leaf hot water extract has antibacterial effect with zones ranging from 14.500± 0.009 mm to 1.000± 0.006 mm across the isolates. Cold water extracts recorded the lowest zones of inhibition from this study for the stem and Bark antibacterial activities. The stem of A. muricata has higher inhibitory effect on the test isolates compared to the leaf of      A. muricata.

ABSTRACTDormancy is exhibited in many seed producing plants. It could be endogenous or exogenous, depending on the plant and the type of seed the plant produce. A survival strategy, plant use to conserve their genetic materials during unfavourable conditions. Scarification treatments has been used in this work to break the dormancy ofAnacardium occidentale, Annona muricata, Jatropha curcas, Tamarindus indicaandArtocarpus heterophyllususing 65% Nitric acid (HNO3), 65% Sulphuric acid (H2SO4), 0.5% Potassium tetraoxosulphate(VI) (K2SO4), 0.5% Urea (CH4N2O), 43% Ethanol (C2H6O) and Distilled water. Nitric acid (65% HNO3) produced the best result forAnacardium occidentalewith high numbers of seedlings and a germination period of 15 days.Jatropha curcasdid not produce a favourable result from the treatments.Tamarindus indica,water treatment produced the best result with six days of germination shorter than the controlled value (16 days). Nitric acid (65% HNO3) and water favorAnnona muricatawith germination period of 19 days as against 24 days for control experiment. Water and Potassium sulphate are the best treatments forArtocarpus heterophyllusas they produce viable seedlings with short germination period of 14 and 15 days which give a good result better than the 18 days of the control experiment.

Objetivou-se testar a atividade inseticida de pós vegetais em Sitophilus zeamais. Foram testados os pós de Anadenanthera colubrina (folhas); Annona muricata (sementes); Azadirachta inidica (folhas e flores); Caesalpinia pyramidalis (folhas), Chenopodium ambrosioides (folhas e flores); Cymbopogon sp. (folhas); Cymbopogon citratus (folhas); Momordica charantia (folhas e frutos); Piper nigrum (sementes); e Ricinus communis (folhas). Além disso, avaliou-se o potencial inseticida de folhas e flores de C. ambrosioides em diferentes dosagens. Na avaliação de repelência foi estabelecido um índice de preferência, e utilizado o teste t para comparação das médias das espécies vegetais. Também foi realizada a comparação das médias das plantas que foram classificadas como repelentes. Para avaliação da mortalidade, procedeu-se a análise de variância e a comparação das médias pelo teste de Tukey e também o teste t para comparação das médias dos tratamentos C. ambrosioides e P. nigrum. Os dados de emergência foram analisados pelo teste de Tukey. Para avaliar os dados de mortalidade, ocasionados por C. ambrosioides, determinou-se a CL50 utilizando a análise de Probit. Os dados de emergência foram verificados pela análise de regressão. As plantas que provocaram repelência foram Cymbopogon sp., C. citratus e C. ambrosioides. A planta que mais afetou a sobrevivência da praga foi C. ambrosioides, que provocou mortalidade total dos insetos infestantes e nenhuma emergência. Adultos de S. zeamais são mais suscetíveis a concentração de 0,125 g do pó de C. ambrosioides.

Abstrak. Insektisida nabati adalah insektisida yang berasal dari tumbuhan dan insektisida itu sendiri adalahbahan yang dapat digunakan untuk mengendalikan populasi Organisme Pengganggu Tanaman (OPT) terutamapada masalah penanganan pasca panen tanaman jagung. Hama Sitophilus zeamais M merupakan hama yangmenyerang biji jagung sejak di lapangan dan di penyimpanan serta tingkat serangan S. zeaimais bersifatmerugikan. Beberapa tumbuhan berpotensi sebagai insektisida nabati terhadap hama S. zeamais adalah daunbabadotan (Ageratum conyzioides L), bunga cengkeh (Eugenia aromatica), daun mimba (Azadirachta indica)dan daun sirsak (Annona muricata L.). Penelitian ini menggunakan Ranangan Acak Lengkap (RAL) faktortunggal dengan 5 pasang imago diinfestasikan pada 10g masing-masing serbuk nabati dan 100g biji jagung.Hasil penelitian menunjukkan bahwa serbuk bunga cengkeh efektif pada pengamatan persentase daya repelensitertinggi yaitu 98,33% 2 jam setelah aplikasi, mortalitas tertinggi yaitu 85% 8 hari setelah aplikasi, lama imagomuncul 9,17 (hari ke-55), jumlah imago muncul paling sedikit yaitu 0,33% dan kerusakan biji terendah yaitu0,46%. efficacy of several types of vegetable powder as an insecticide against Sitophilus zeamais motsch pests in corn stored Abstract. Biopesticide are insecticides derived from plants and insecticides themselves are materials that can beused to control the population of Plant Pest Organisms (OPT), especially on the problem of handling afterharvesting corn crops. Sitophilus zeamais M pest is a pest that attacks corn seeds since in the field and is storedand the level of attack of S. zeaimais is detrimental. Some plants that have the potential as vegetable insecticidesagainst S. zeamais pests are babadotan leaves (Ageratum conyzioides L), clove flowers (Eugenia aromatica),neem leaves (Azadirachta indica A. Juss) and soursop leaves (Annona muricata L.). This study uses acompletely randomized single design (RAL) single factor with 5 pairs of imago infested in 10 g of eachvegetable powder and 100 g of corn seeds. The result showed that the clove flower powder was effective inobserving the highest percentage of repelency power which was 98.33% 2 hours after application, the highestmortality was 85% 8 days after application, imago duration appeared 9.17 (day 55), the number of imagoappeared the least is 0.33% and the lowest seed damage is 0.46%.
