Abstract

Spodoptera exiqua is known as onion caterpillar, it attacks often reduces onion production.  This insect could even cause harvest failure, and chemicals in high doses and spraying is often used to control on its spread. This action can negatively impact to environment as well the users. To reduce the negative impact of the use of chemical insecticides is necessary to find an alternative strategy. It is known that several biological agents could serve as biopesticides such as  entomopathogenic nematodes Steinernema sp. This study was aimed to determine effective concentration of entomopathogenic nematodes Steinernema sp. to control S. exiqua growth.  Nematode used in this study was Infective juvenile (IJ) instar II. There were 6 different nematodes concentrations as treatments and each treatment was repeated 4 times in a Completely Randomized Design (CRD).  The treatments were 0 IJ, 200 IJ, 400 IJ, 600 IJ, 800 IJ, and 1000 IJ of nematodes, mixed in 2 ml of distilled water, respectively.  The results showed that the concentration of nematodes 600 JI is effective to kill 83.4% larvae of S. exiqua within 6 days. This finding clearly shows that nematode is able to reduce larvae S.exiqu and expecting a positive impact to onion production.

Abstract

The research was conducted in the Soulowe of village, District Biromaru, Sigi. Experimental design used was Randomized Block Design (RBD) with 3 (three) treatments and 5 (five) replications, in order to obtain 15 units of the experiment.  Each treatment is based on the differences in varieties. These varieties are varieties Bonanza, Paramita and Kumala. The variables measured were the intensity of the attacks and the rate of infection diseases. The first observation made at the time the plant was 14 days after planting, subsequent observations made at intervals of once a week as much as 7 times. The results of this study showed that the difference in response of resistance varieties Bonanza, Paramita and Kumala against downy mildew caused by the fungus Peronosclerospora maydis. The highest attack intensity was found in varieties Bonanza followed by Kumala varieties, while the lowest was found in varieties Paramita. The highest disease infection rate was varietas Bonanza, then followed by Kumala varietas, and then Paramita varieties that have the lowest disease infection rate.

Abstract

The purpose of this study was to determine the pathogenicity (Lethal Concentrate = LC 50 value) of entomopathogenic Steinernema spp. and Heterorhabditis spp. nematodes against caterpillar pests of onion S. exiqua. This study was conducted during October to December 2013,  in the Pests and Plant Diseases Laboratory, Agriculture Faculty, Tadulako University of Palu. This researchused a Completely Randomized Design (CRD) in atwo factorial experiment. The factors were type of nematodes and concentration.  Each treatment was replicated three times, so that there were 24 experimental units. The nematodes used in this study were third in star nematodes. The concentration of the nematodes use dincluding 500 IJ per 4ml water (p1), 750 IJ per 4 ml water (p2), 1000 IJ per 4 ml water (p3)and 1250 IJ per 4 ml water (p4). The results showed that the mortality of S. exiqua larvae increases with rising nematod concentration. Highest mortality found during one day after application (DAA) to 6 DAA was under 1250 IJ (p4) so it is the most effective and efficient concentration to be implemented for controlling S. exiqua larvae. The estimated value of LC 50 using probit analysis is 425.64 IJ ml-1 water with the range of 244.77 to 740.16 IJ ml-1 water, in this case about 425- IJ ml-1 water is required to halve the number of the tested insects within     six days. Key Words : Heterorhabditis spp, pathogenicity. Spodoptera exiqua H., and Steinernema spp nematodes.

Abstract

Central Sulawesi is largest of cocoa bean producer in Indonesia. However, cacao production constrained by important diseases. Currently, data about cacao been damage due to pathogen infection have not been updated. This study observed the incidence of major diseases in cacao plantations, included pod rot, canker, and vascular-streak dieback (VSD). The study was situated at the largest cacao plantation in Central Sulawesi, in Ampera, Berdikari, Bahagia, Ue Rani, and Sejahtera villages in Palolo District, Sigi Regency. The observation pronounced that the cacao trees in the study sites were infected by the pathogens of pod rot, canker, and VSD with different incidence levels. VSD was a disease with the highest incidence and distribution in the cacao plantations. Besides, this study also described the symptom of the disease.

Abstract

Antagonist fungi have enormous potential to be a biological agent to control Fusarium basal rot (FBR) disease in shallot. This study aims to explore, isolated, and tested the antagonistic of Trichoderma sp. indigenous isolated from shallot fields against FBR disease. Exploration of isolates was carried out at the shallot planting center in Sigi Regency. The isolation characterization and inhibition tests were carried out at the Laboratory of Plant Pathology Tadulako University. The inhibition test was using two culture methods. The results showed that there were Trichoderma sp. obtained from shallot fields in the village of Sidera. In vitro test results showed Trichoderma sp., which was found to be able to inhibit the growth of the fungus F. oxysforum. The highest inhibition reached 69.18% within six days. As a comparison of inhibition of Trichoderma harzianum, a laboratory collection, within 6 days only reached 61.06%. Trichoderma sp. the origin of shallot fields was more effectively used as a biological agent in controlling FBR disease.

Abstract

One of the significant diseases afflicting shallots (Allium ascalonicum L) is the purple spot disease (Alternaria porri), leading to substantial harm. The objective of this investigation was to assess the efficacy of papaya leaf extract (Carica papaya L.) against Alternaria porri, the causative agent of purple spot disease in shallots (Allium ascalonicum L.). This research employed a completely randomized design (CRD) with six concentrations of papaya leaf extract (0%, 1%, 2%, 3%, 4%, and 5%) as treatments. The most effective treatment was observed at a 5% extract concentration, which resulted in the slowest expansion of the A. porri colony diameter (1.60 cm) and the most substantial inhibition percentage (77.21%). These outcomes were significantly different from the control treatment, wherein A. porri colony growth reached 6.17 cm and the inhibitory effect was only 16.22%.

Abstract

Tomat (Lycopersicon esculentum Miller) merupakan salah satu komoditas hortikultura yang memiliki nilai ekonomi penting di Indonesia. Badan Pusat Statistik (2019) menunjukkan rata-rata produksi dan produktivitas tomat di Sulawesi Tengah menurun. Pada tahun 2017 produksi tomat mencapai 22,490 ton, akan tetapi pada tahun 2018 turun menadi 16,161 ton dan 16,516 ton pada tahun 2019. Produktivitas tomat dapat dipengaruhi oleh beberapa hal, salah satunya yaitu oleh penyakit tanaman. Salahsatu penyakit pada tanaman tomat adalah penyakit rebah yang disebabkan oleh jamur S. rolfsii. Penyakit rebah semai yang disebabkan oleh S. rolfsii merupakan sakah satu penyakit yang menyerang tanaman tomat pada masa persemaian, yang menyebabkan pembusukan pada persemaian atau pada tajuk tanaman muda.T. harzianum adalah jamur akar hijau yang bersifat antagonis pada beberapa jenis jamur dan serangga lainnya. Distribusi jenis jamur ini sangat luas dan terdapat pada hampir semua jenis tanah dan habitat alam lainnya, khususnya pada tempat-tempat yang mengandung bahan organik. Penelitian ini bertujuan untuk menenukan potensi T. harzianum dalam mengendalikan cendawan S. rolfsii penyebab penyakit rebah semai pada tanaman tomat. Manfaatnya yaitu untuk menjadi referensi bagi penelitian berikutnya dalam aplikasi T. harzianum dalam mengendalikan cendawan S. rolfsii penyebab penyakit rebah semai pada tanaman tomat dan mengurangi penggunaan pestisida kimia dalam mengendalikan cendawan S. rolfsii tersebut. Penelitian ini dilaksanakan di Laboratorium Hama dan Penyakit Tanaman, Fakultas Pertanian, Universitas Tadulako, Palu. Mulai bulan November 2020 sampai bulan Februari 2021. Variabel pengamatannya yaitu Masa Inkubasi Cendawan S. rolfsii dan kejadian penyakit. Hasil penelitian pengamatan kejadian penyakit pada masing-masing perlakuan memberi pengaruh sangat nyata dalam menghambat pertumbuhan cendawan S. rolfsii. Daya hambat paling efektif terjadi pada perlakun P5 dengan rata-rata 33%.
