Abstract

Research on the application of billygoat weed, lantana, and cogon grass leaves extracts on anthracnose disease in chili plants. This research aims to determine the fungicidal activity of billygoat weed, lantana, and cogon grass leaves extracts on the growth and development of anthracnose disease in chili plants. This research method includes the extraction of billygoat weed, lantana, and cogon grass leaves, Potato Dextrose Agar (PDA) media preparation, Colletotrichum capsici fungal isolates breeding, and in vitro and in vivo testing. The research was conducted in the laboratory with three types of treatments arranged in a completely randomized design (CRD). The results of in vitro testing showed that billygoat weed, lantana, and cogon grass leaves extracts were able to inhibit the growth of Colletotrichum capsici colonies ranging from 0.50-1.24 cm, 80.58-92.15% inhibitory capacity, 0.16x1060.22x106 spore density at 7 days after inoculation and testing. The results of in vivo testing showed that billygoat, lantana, and cogon grass leaves extracts were able to reduce disease severity between 12.50-16.00%, disease incidence ranging from 26.00-30.00%, and chili fruit weight loss of 28.97-32.92%. Billygoat weed, lantana, and cogon grass leaves extracts have the potential as a botanical fungicide in controlling anthracnose disease in chili plants.

Abstract

Chili is included in horticultural commodities cultivated by Indonesian farmers. Red chilies are annual shrubs classified as vegetables the community needs as kitchen necessities. Expired seeds are seeds that have experienced a decline in growth and yield. Growth hormones can be used to increase the existing hormone levels and seed germination. Gibberellins are plant growth regulators that accelerate seed germination. Gibberellin is an essential organic compound in seed germination because it controls the process. The research was conducted to determine the effect of Gibberellins concentration and soaking time on the viability and vigor of expired red chili seeds. This research used a completely randomized design (CRD) with two factors. The first factor is the soaking time (P), which consists of 3 levels: 4 hours soaking (P1), 8 hours soaking (P2), and 12 hours soaking (P3). The second factor was the concentration of gibberellins (K), which consisted of 4 levels, which are 0 ppm (K0), 100 ppm (K1), 200 ppm (K2) and 300 ppm (K3).

Abstract

Lemon (Citrus lemon L.) is one of the horticultural commodities used by Indonesian people in the form of juice or combined with cooking spices. The materials used for lemon cutting plants were topsoil, manure, coconut water, water, labeling paper, transparent plastic, and polybag size 12 x 17 cm. The tools used in this research were: hoe, machete, scissors, bucket, bamboo, paranet, raffia rope, meter, camera, watering can, measuring cup, scale, oven, and stationery. This research used Randomized Block Design (RBD) with a factorial pattern. The first factor was the length of the cuttings, and the second factor was the concentration of coconut water (0% (control), 25%, 50%, and 75%). It was repeated three times so that there were 36 experimental units.

Abstract

Accurate information on the species and host spectrum is an important aspect of fruit flies management. The study was conducted in August to November 2018 to evaluate the host range and species diversity of fruit flies in Lembah Seulawah District, Aceh Besar Regency, Aceh Province, Indonesia. Fruit flies were collected from 3 villages in Kemukiman Saree: Suka Damai, Suka Mulia, and Saree Aceh. The insects were collected using the trapping method. The modified Lynfield trap baited with methyl eugenol (ME) was used in the research. This modified Lynfield trap was applied using used mineral bottles. Shannon-Wiener diversity index, evenness index, and dominance were applied to determine the diversity of fruit flies. The results revealed that there were six species of fruit flies that acted as pests in 21 species of host plants belonged to 12 families. They were Bactrocera carambolae, Bactrocera latifrons, Bactrocera limbifera, Bactrocera papayae, Bactrocera umbrosa, and Bactrocera verbascifoliae. B. carambolae was found to be dominant insect pest even though the results indicated that diversity and evenness index of fruit flies species in this district were low.
