Abstract

Macrosiphoniella sanborni is a main concern in the production of ornamental chrysanthemum plants. Farmers commonly use chemical treatment to control aphids, but this can harmful the environment and humans. Therefore, alternative environmentally control is needed, one of which is by using botanical pesticides such as Azadirachta indica and Barringtonia asiatica. This research aimed to test the effectiveness of the neem and bitung seed extract against M. sanborni pests on chrysanthemum plants. This research was conducted at the Chrysanthemum cultivation Mr. Syarif’s screen house in Karyawangi village, Parongpong district, West Java, which began in January 2021 to May 2021. This research used an experimental method using a Randomized Complete Block Design (RCBD) which each experiment consisted of 10 treatments and each treatment was repeated 3 times. The tested treatments are neem and bitung seed extract in different concentration, and controls. The results of this study revealed that the effective treatment of M. sanborni on chrysanthemum is the extract of bitung seed at the concentration of 2%. Bitung seed extract pesticides can be used as an alternative synthetic pesticide to control population of M. sanborni.

Abstract

Strawberry production is often decreased by plant pest infestation in the field. One of the major pests is Aphis gossypii. Strawberry farmers typically use synthetic chemical pesticides to control aphid, however, this can pose serious environmental and human health problems if done continuously. The use of synthetic chemical pesticides can be minimized by using botanical pesticides, as they are safer for human health and the environment. Botanical pesticides that can be used include neem seed extract (Azadirachta indica) and sea poison tree (Barringtonia asiatica). The objective of this research was to test the effectiveness of neem and sea poison tree seed oil formulations against A. gossypii on strawberry plants. The experiment was conducted at CV Bumi Agro Technology, Lembang, from April 2023 to August 2023, arranged in the randomized complete block design consisting of 7 treatments with 4 replications. The treatments were application of neem and sea poison tree seed oil at different concentrations, as follow: (A) Control, (B) Abamectin 0.15%, (C) Neem Oil 2%, (D) Neem seed oil 50 EC 2%, (E) Neem seed oil 50 EC 1%, (F) Sea poison tree seed oil 30 SC 2%, and (G) Sea poison tree seed oil 30 SC 1%. The results showed that neem and sea poison tree seed oil formulations at the concentration of 2% were effective in controlling A. gossypii on strawberry plants.

Abstract

The Cultivated Area in Kamojang Crater, Ibun District, Bandung Regency is part of a single landscape mountain, adjacent to conservated and protected areas which has high biodiversity. This study aims to identify invasive alien plants species in cultivated areas, adjacent to conservation and protected areas. The method used is a descriptive qualitative study with the sampling line transect in 500 meter radius of four location, namely near Nature Reserves (NR), near Nature Tourism Parks (NTP), agriculture (A) and near Protected Forests (PF), and this study has done up at July until November, 2022. The results showed that in the cultivated area in Kamojang Crater, Ibun District, Bandung Regency found 41 families and 96 species of understorey, with the highest number being from the Asteraceae, Poaceae and Fabaceae. Diversity of understorey was categorized as high (H'=3.428), evenly distributed (E=0.738), high species richness (R=13.503) and no dominant species (C=0.165). Several understorey, namely 8 orders, 10 families, and 29 species were categorized as invasive aliens plant species, with the highest important values index being Ageratina riparia (99,642%), Imperata cylindrica (72,919%), Paspalum notatum (31,155%), Chromolaena odonata (31,074%), Etlingera elatior (27,905%), Ageratum conyzoides (20,179%), Lantana camara (19,029%), Amaranthus hybridus (18,818%), Pennisetum purpureum (15,120%), Mimosa pudica (15,031%), Crassocephalum crepidioides (14,037%), and Axonopus compresus (10,671%).
