Abstract

Penelitian pengaruh beberapa jenis pestisida nabati terhadap serangan hama pada teh telah dilakukan di PTPN VIII, Perkebunan Teh Gedeh, Cianjur, Jawa-Barat tahun 2011. Tujuan penelitian adalah untuk mendapatkan formula pestisida nabati efektif terhadap hama teh. Penelitian dirancang dalam acak kelompok dengan enam perlakuan, yaitu formula (1) sitronellal; (2) eugenol; (3) rotenon; (4) azadirachtin; (5) campuran sitronellal, rotenon, eugenol, dan azadirachtin; dan (6) kontrol (air), masing-masing dengan konsentrasi lima ml l-1 air, diulang empat kali. Pengamatan dilakukan terhadap intensitas serangan pada pucuk teh sebanyak empat kali panen. Hasil menunjukkan semua formula pestisida nabati efektif mengendalikan intensitas serangan tiga Organisme Pengganggu Tanaman (OPT) pada pucuk teh, yaitu ulat jengkal (Plusia calchites), Empoasca (Empoasca sp.) dan Helopeltis (Helopeltis spp.) rata-rata 30%, kecuali eugenol yang belum menunjukkan kemampuannya dalam menekan serangan Helopeltis spp. Eugenol menunjukkan gejala fitotoksik pada pucuk teh (pucuk teh terlihat seperti terbakar). Walaupun terdapat perbedaan yang signifikan dalam menekan kerusakan pucuk daun teh, semua formula belum memberikan hasil yang memuaskan karena masih relatif tingginya pucuk teh yang terserang OPT. Hal ini diakibatkan oleh faktor iklim, dimana embun dan curah hujan relatif tinggi di lokasi penelitian, sehingga mudah mencuci formula pestisida nabati pada pucuk teh. Oleh karena itu, untuk penelitian kedepan perlu penambahan bahan perekat nabati seperti dari Sapindus rarak pada semua formula yang diuji.

Abstract

Research has been conducted at farmer’s fruit garden in Cilebut area, Bogor during 1997–1998. The objective is to know the effect of some application techniques of oil distilled from Melaleuca bracteata leaves on trapping fruit fly. Research consisted of three activities, those were the effect of some techniques of application on trapping fruit flies (I) weekly, (2) in two weeks and (3) the effects of some concentrations of methyl eugenol (ME) on trapping fruit fly. All treatments were hung at the fruit trees as high as 1.5 m. Observations were done in the number and gender of fruit flies trapped weekly and two-weekly. Result revealed that melaleuca distilled oil can be applied either by dropping into water or into cotton ball. Melaleuca leaves distilled oil should be applied once in two weeks, since its effectiveness lasted for two weeks only. The minimum concentration of methyl eugenol which could fruit flies effectively was 57%.

Abstract

Research has been carried out at the Pest and Disease Laboratory, Research Institute for Spices and Medicinal Crops, Bogar, in the 1997. Research consisted of three parts, those were; (I) The toxicity of Dens elliptica, Blumea balsamifera, and methaldehyde, by determining the LC50 values, (2) Effect of the leaves of B.balsamifera, Euphorbia tirucalli and Tephrosia vogelii, (3) Effect of the most poisonous plant as ovicides. Result showed that D.elliptica was the most poisonous material to golden snail with its LC50 value was 400ppm, but it was still under the toxicity value of methaldehyde (11. 78 ppm). There was no significant difference among B.balsamifera, T.vogelii and E. canaliculata, but extract of B.balsarnifera tended to be better material among those plant extracts tested. The extract of D.elliptica did not affect egg hatching of golden snail.

Abstract

[THE INFLUENCE OF BOTANICAL INSECTICIDES BASED ON CROTON OIL AND DERRIS ROOT AGAINST BROWN PLANTHOPPER]. Brown planthopper (BPH) (Nilaparvata lugens Stall) is a serious pest in rice. Using synthetic insecticide to control BPH is harmful for human health and can caused environmental pollution. The objective of this research is to find out ecofriendly insecticide to control BPH. Research has been conducted at Entomological laboratory, Indonesian Spice and Medicinal Crops Research Institute (ISMECRI), Bogor. It was designed with CRD, 16 treatments and 3 replications. Treatments consisted of botanical insecticides based on Croton tiglium and Derris elliptica. Each material was extracted by water, methanol, and xylene, and then tested by individually and combination, so there were 15 formulas and 1 control treatment (water). Third nymph BPH and IR64 rice variety were used in this research. Research was done in two methods, i.e. contact application and residual application. The result shows that there are 11 formulas which are prospective to be further developed i.e aqueous extraction (6 formulas) and combination extraction (aqueous with xylene and methanol (5 formulas). The aqueous extraction maybe the most prospective formulation since the technique could easily be adopted by farmers. Botanical pesticide based on Croton tiglium and Derris elliptica are very promising, therefore the research should be continued to find out the best formula of botanical insecticides for controlling BPH).
