The experiment was conducted in a farmer’s field in Kecamatan Galesong, Takalar Disrict, South Sulawesi Province, Indonesia. Soybean cv. ‘Mahameru’ seeds were manually planted using a wooden drill with planting space of 28 inches between rows and 10 inches within a row on 5 Jul 2011. The insecticide treatments and an untreated check were arranged in an RCB design with four replications. Each replication consisted of a plot of 8 plant rows wide and 33 ft long. There was 10 ft of bare space between plots. Cultural practices, such as fertilizing and watering, were in accordance with the local recommendations. Insecticides were applied on 10 Aug using a backpack sprayer delivering about 50 gpa. To determine aphid population levels, five plants in the middle two rows of each plot were randomly selected. Numbers of aphids per plant were counted on 17, 24 and 31...

The research was conducted in two main rice producing areas of the province, Soppeng and Maros Regencies. Simple random sampling was employed in selecting 20% of the total populations, resulting in sample sizes of 69 repondents in Soppeng and 52 respondents in Maros. A structured questionnaire was used in direct interview with the selected respondents to obtain data on their socio-economic profile, IPM implementation, and profit gained from IPM. Percentage was used to present the data. In both regencies, overall IPM adoption rates were high with most respondents were categorized as medium and high IPM adopters with adoption rates of 85.1% in Soppeng and 88.5% in Maros. The medium and high IPM adopters gained more economic profits of 26.9% in Soppeng and 16%% in Maros in comparison to the low IPM adopters. The high adoption rates indicated that although the na...

Determination of P. oryzae races was conducted using 1 set of rice differential varieties consisting of Asahan, Cisokan, IR 64, Krueng Aceh, Cisadane, Cisanggarung, and Kencana Bali. The intensity of blast disease was observed seven days after inoculation using the Standard Evaluation System for Rice (IRRI) evaluation standard using a 5-9 scale of the necrotic area to determine the host resistance level. Based on morphological observation, 20 isolates were referred to as P. oryzae. Inoculation of P. oryzae isolates on 7 differential varieties of rice showed, that 12 races (000, 001,003,010, 020,023, 100, 102,110,111,173, dan 251) existed between P. oryzae isolates tested. However, the 020 races were dominant in all districts were samples were collected.

It sucks plant sap, emits honeydew on which sooty mold fungi grow, and transmits the pepper yellow leaf curl Indonesia virus (PepYLCIV), the most damaging viral disease of chili in Indonesia. Farmers rely mainly on insecticide to control the insect with two to three sprays in a week. To reduce the insecticide use, an integrated approach needs to be developed. Therefore, the current study evaluated the effectiveness of the integration of reflective mulch, host plant resistance, and insecticide use for managing the sweet potato whitefly on the chili pepper. In 2018, a complete randomized block design was used in three separate trials to assess the effects of mulch, cultivar, or insecticide application frequency on the numbers of whitefly eggs, nymphs, and adults. In 2019, a split-split plot design was used to evaluate the effects of the integration...

The purpose of research is to identify pest of long bean flowers in farmer field that reduce loss yield. The survey about presence of insect-pest incidence conducted at long bean field in Pakkabba village, north Galesong district, Gowa Regency, South Sulawesi (5°14’8’’S, 119°24’1’’E) in July 2019. Visual observation in long bean field was conducted diagonally in fivesampling points (used 10 long bean flowers from three plants per sampling point). The sample contained symptoms of long bean pest were collected, identified and recorded. The result show spotted pod borer Marucatestulalis Geyer (Lepidoptera: Crambidae) after mass rearing pest in laboratory. Based the survey, this is potential pest caused loss yield of long bean and need more working manage it.

The objectives of the research were to identify butterfly species and their host plant served as larvae food, nectar and pollen source in three different altitudes at Bantimurung-Bulusaraung National Park. The research was conducted based on transect methods at Bantimurung-Bulusaraung National Park, Maros Regency, South Sulawesi, Indonesia from April to October 2018. Butterflies and their food were observed in three locations at different altitudes of 0-300 m above sea level (asl), 400-700 m asl, and above 700 m asl. The observation indicates a variation in the butterfly species found in different altitudes based on the presence of host plants. A total of 59 individual butterfly samples collected were divided into four families: Papilionidae (7 species), Pieridae (2 species), Nymphali...
