The objective of this research is to study the effect of some concentrations of neem leaves extractin controlling anthracnose disease on post-harvested red chilli fruits. A research has been conductedexperimentally using a Completely Randomized Design, consisting of 6 treatments and 5 replications. Thetreatments are 6 concentrations of neem leaves extract : 0%=M0, 1%=M1, 5%=M2, 10%=M3, 15%= M4and 20%=M. Result of the research indicated that the concentration of neem leaves extract gave differenteffect in controlling anthracnose disease of the red chilli fruits. The concentration of neem leaves extractat 15% and 20% gave a better effect in controlling anthracnose disease of post-harvested red chilli fruits,which resulted in a smaller diameter of in-vitro fungi colony growth, a longer incubation period of thedisease and a lower incidence of the disease.

Cassava (Manihot utilissima) is the third food source in Indonesia. Cassava commodity has economic value and is widely planted in the Technical Implementation Unit of the Agricultural Extension Agency (UPTBPP) Kulim, Pekanbaru City. This service aims to provide knowledge and skills to cassava farmers in the Technical Implementation Unit of the Kulim Agricultural Extension Agency (UPTBPP) of Pekanbaru Municipality about the types of pests and diseases that attack, symptoms of attacks, and their control techniques. The target of service is mainly cassava farmers in the Technical Implementation Unit of the Agricultural Extension Agency (UPTBPP) Kulim Pekanbaru Municipality so that farmers' incomes become better and more prosperous. The service method used the method of counseling and demonstration. The extension method uses LCD and infocus, pictures of pests, life cycles, damage are presented, along with explanations of control techniques. The demonstration method includes the practice of control techniques consisting of first introducing natural enemies in the form of videos, making glumon traps and making forest betel leaf and soursop vegetable pesticides. The measuring instrument for achieving the goals of service was the understanding and knowledge of farmers about pests and diseases of cassava plants, controlling cassava pests and changing farmers' views on pest control no longer prioritizing the use of synthetic pesticides and the ability of farmers to recognize the types of natural enemies of pests. Achievement is measured by distributing questionnaires to determine changes and increase in farmer knowledge. The results of the service program in the form of counseling and demonstrations were very well responded by cassava farmers. Participants paid close attention, asked many questions. The results of the questionnaire assessment of farmers showed an increase in farmers' understanding of controlling pests and diseases of cassava plants after service activities. Thus this service will provide great benefits to cassava farmers in controlling pests and diseases in cassava cultivation.

Seedborne diseases on rice seeds can be controlled by using plant extracts which applied by seed treatment. The plants used, such as: green betel leaves extract, turmeric rhizome, and ketepeng cina leaves extract. The aim of this research is to study the effect of aplication of several plants extract and obtain the best extract to control fungal pathogenic on rice seeds and the effect to germination rice seeds. The research has been conducted at laboratory plant disease and greenhouse Experimental Field of Faculty of Agriculture, Riau University Pekanbaru. This reseach has been conducted experimentally by using a completely randomized design (CRD) consisting of 4 treatments, namely: without addition plants extract (E0), green betel leaves extract 40% (E1), turmeric rhizome 25% (E2), and ketepeng cina leaves extract 15% (E3). The result showed that the application of ketepeng cina leaves extract could inhibit the growth of Pyricularia sp. 36,50%, Alternaria sp. 76,00% and Drechslera sp. 58,50%, but not contaminated fungi, such as: Rhizopus sp., Aspergillus sp., Mucor sp. and Penicillium sp. The application of the three plants extract were not able to affect seed germination rate, sum of normal seed growth, seedling growth and the decreatesum of symptomatic disease seedlings.

Colletotrichum capsici is the cause of anthracnose disease on red chili plants that causes a significant decrease chili production in Riau Province. One of the control techniques that can be applied is biological control using endophytic fungi isolated from plants, including sago plants. This study aims to evaluate the consortium of four endophytic isolates of sago plants and to obtain the best consortium of endophytic isolates in inhibiting the fungus, C. capsici which causes anthracnose disease on red chili. This research was carried out at the Plant Disease Laboratory, Faculty of Agriculture, Riau University from June to September 2021. The research was carried out experimentally using a completely randomized design. Four isolates TRA (Trichoderma sp. from root), TRP (Trichoderma sp. from leaf), TRB (Trichoderma sp. from stems) and TV (Thielaviopsis sp.) were compatible and could be consorted. Consortium of TRP+TV, TRA+TRB+TV, TRA+TV, TRB+TV and TRA+TRP+TRB+TV had the ability to inhibit the growth of the fungus C. capsici on PDA medium. Consortium TRP+TV had the highest inhibition potency to C. capsici, which was 61.67%. Consortium TRB+TV had the best ability to delay the initial emergence of disease symptoms and to decrease the disease intensity on red chilli fruits, which was 29.67%.

SELEKSI JAMUR ENDOFIT TANAMAN NIPAH (Nypa fruticans Wurmb.) DAN UJI ANTAGONISME TERHADAP Ganoderma boninense Pat. PENYEBAB PENYAKIT BUSUK PANGKAL BATANG KELAPA SAWIT SERTA IDENTIFIKASINYA Surya, Arifah Hasnita; Ali, Muhammad; Venita, Yunel

Penelitian ini bertujuan untuk menyeleksi dan mendapatkan isolat jamur endofit dari tanaman nipah (Nypa fruticans) yang berdaya antagonis tinggi terhadap G. boninense penyebab penyakit busuk pangkal batang (BPB) pada tanaman kelapa sawit secara in vitro serta mengidentifikasinya hingga tingkat genus. Penelitian dilakukan di Laboratorium Penyakit Tanaman Fakultas Pertanian Universitas Riau dimulai dari November 2020 hingga Februari 2021. Penelitian ini dilakukan dengan menggunakan metoda eksplorasi (isolasi dan pemurnian jamur endofit tanamn nipah), observasi (uji hipovirulensi isolat jamur endofit tanaman nipah, uji hiperparasitisme jamur endofit tanaman nipah yang memiliki daya antagonis tinggi terhadap G. boninense dan identifikasi isolat jamur endofit tanaman nipah yang memiliki daya antagonis terhadap G. boninense) dan eksperimen (uji daya antagonis jamur endofit tanaman nipah terhadap G. boninense, uji diameter dan kecepatan tumbuh koloni isolat jamur endofit tanaman nipah yang memiliki daya antagonis tinggi terhadap G. boninense). Data karakteristik makroskopis, hipovirulensi, hiperparasitisme dan identifikasi jamur endofit antagonis tinggi disajikan secara deskriptif dan disajikan dalam bentuk tabel dan gambar. Data antagonism, diameter pertumbuhan dan laju pertumbuhan jamur yang berdaya antagonis tinggi dianalisis dengan analisis ragam dan untuk membandingkan rata-rata perlakuan dilanjutkan dengan uji duncan’s new multiple range test (DNMRT) pada taraf 5%. Hasil penelitian diperoleh 20 isolat, dimana 14 isolat adalah jamur yang bersifat hipovirulen dan 6 isolat bersifat virulen. 6 isolat memiliki nilai daya antagonis lebih tinggi terhadap G. boninense. Isolat N17 (jamur endofit asal daun tanaman nipah) yang memiliki nilai antagonis tertinggi dan berpotensi sebagai agens hayati yaitu 71,33% dengan diameter kecepatan tumbuh 89,75 mm serta 24,48 mm.hari-1. Tipe interaksi hiperparasitisme masing-masing jamur endofit tanaman nipah berbeda-beda yaitu penempelan (N7), pelilitan (N17 dan N14), penjeratan (N8) dan lisis (N5 dan N16). Hasil identifikasi menunjukkan bahwa isolat N7 termasuk kedalam genus Aspergillus sp., isolat N8 termasuk kedalam genus Gliocladium sp. dan 4 isolat lain yaitu N5, N14, N16 dan N17 belum teridentifikasi.
