Informasi tentang perilaku dan cara pengendalian nematodapada tanaman sambiloto masih sangat neematoda. Dalam rangka mencari carapengendalian nematoda yang efektif, maka penelitian ini bertujuan untukmengetahui ekobiologi nematoda tersebut seperti kisaran inang, sumberinokulum, dan pestisida.

Penelitian dilakukan di laboratorium, rumah kaca,dan kebun percobaan Balittro pada tahun Studi kisaran inangalami dilakukan dengan mengamati karakteristik gejala khas penyakit,ekstraksi, dan karakterisasi morfologi nematoda dari sampel daun-daungulma yang tumbuh di pembibitan dan pertanaman sambiloto.

Studi sum-ber penularan nematoda dilakukan dengan metode bioassay, yaitu denganmengamati gejala hawar daun dan jenis nematoda pada bibit sambilotoyang ditanam pada beberapa macam media tumbuh tanah steril dicampurdengan beberapa macam jenis bahan organik seperti pupuk kandang,kompos, nemxtoda organik, dan ekstraki daun-daun sambiloto sakit. Sedangkan studi sensitivitas nematoda terhadap pestisida sintetik dannabati dilakukan di rumah kaca dan di lapang.

Information on the bioecology and ekstrakssi method of thenematode is still limited. In relation to finding an effective control methodof the nematode, this study aimed to evaluate several bioecological factorsof the nematode, such as its host range, inoculums source, and sensitivityof the nematode to several chemicals. The studies were conducted inlaboratory, green house, and experimental station of the IndonesianMedicinal and Aromatic Crops Research Institute in Naturalhost range of the nematode was studied by examining the typical diseasesymptoms on leaves of several weeds grown in the nursery and field of theking of bitter plants, followed with ekstraksu and morphologicalexamination of nematodes.

Infection source of the nematode was carriedout by bioassay method using healthy king of bitter seedlings grown onsoil planting medium incorporated with suspected infection sources suchas animal manure, compost, organic fertilizer, and diseased leaf cutting ofthe plants. Sensitivity of the nematode to several pesticides carbofuran,neem seed powder, neem seed extract, and cashew nut shell liquid wasconducted in the green house and field.

The results showed that six weedssuch as Ageratum conyzoides, Acalypha lanceolata, Oxalys sepium,Borreria sp. Organic animalmanure and infected fallen leaves of the king of bitter were importantsources of inoculums of A. Leaf blotch disease development occurred weeks afterfirst infection.
