Abstract

AbstractTaxonomic study of beard moss (Usnea spp) at Priangan, was carried out by using morphological, anatomical and chemical's characters. Sample have taken from five area, they are Jayagiri conifer forest (Bandung), Rancakalong conifer forest (Sumedang), Kamojang conifer forest ( Garut), Munjul conifer forest (Ciamis) and Cigorowong conifer forest ( Tasikmalaya). Morphological observation was done on thallus and anatomical observation in medulla, axis and ratio of cortex : medulla : axis. While chemical analysis was conducting by colour test and crystal test. The identification result founded the eleven species, i.e. Usnea baileyi, U.ceratina, U.cornuta, U.filipendula, U. flexilis, U. flexuosa, U.florida, U.glabrata, U.hirta, U. longissima and U. trichodea. Morphological characters that can be used for distinguished of eleven species of Usnea are medulla shape, axisshape, radius of cortex, radius of medulla and diameter of axis. Chemical characters distinguished are reagent K,C, KC and IKI. Based on that characters the key identification have made for Usnea species founded at Priangan and de3scription were arranged for genus and species level. Phenetic analysis done by using NTSY Spc versi 2.0, resulted a Dendrogram which the eleven species of Beard moss can be divided into three branches. The first branch consist of U.baileyi and U.ceratina, the second are U.cornuta, U.flexilis, U.florida, U. flexuosa and U.glabrata and the third branch branch consist of U.filipendula, U.hirta, U.trichodea and U.longissima.

Abstract

Pests, diseases and weeds are considered as organisms that limiting the agricultural productivity. Losses of agricultural productivity originated from the attack of these organisms may be up to 40% to 60%; sometimes in several cases failure of harvests occurred. So far, chemical (synthetic) pesticides are used to control the attack of these organisms. Meanwhile, the use of synthetic pesticides in fact, creates many negative effects on both biotic and abiotic environments, such as pollution against terrestrial and aquatic environments, even killing the vertebrates and husbandry animals, predatory insects, and some economic insects (insect species that benefit to the life of man). Due to the losses created by utilization of synthetic pesticides, therefore a number of scientists and farmers initiated to turn their attention to use the natural pesticides (directly originated from plants) under the light of back to nature principle, although this step is seems to be less effective.Some natural pesticides practiced by West Javan farmers are likely almost disappeared and difficult to be found in the field. It is important to mention some species here such as cujete/kalabas (Cresentia cujete), bratawali (linospora tuberculata), bitter yam/gadung (Dioscorea hispida), sambiloto {Andrographis paniculata), sarikaya {Annona squamosa) and so many more. Some weed species are known used by farmers as natural pesticide like saliara {Lantana camara), ki pahit (Tithonia diversifolia), alang-alang (Imperata cylindrical) and badotan {Ageratum conyzoides). This research is aimed to inventory plant species used by farmers as natural pesticides as to reduce the reliance on synthetic pesticides. Methods of approach to the problem are by library studies (journals, proceedings of seminars, notes etc), field survey and interview to farmers of several districts (Kabupatens) in West Java and Banten Provinces i.e. Sumedang, Majalengka, Sukabumi, Garut, Pandegelang and Serang. Result shows that there are still 130 plant species used as natural pesticides, and 42 natural (plant based raw materials) pesticide formulations used by farmers.
