“…Among the various strategies applied to manage rice blast so far, a combination of leaves extracts of piper and plant growth-promoting rhizobacteria (PGPR), such as Azotobacter, Rhizobium, Bradyrhizobium, Sinorhizobium, Azorhizobium, Mesorhizobium, Allorhizobium, Azospirillum, Pseudomonas, Alcaligenes, Enterobacter, Stenotrophmonas, Acetobacter, Klebsiella, Xanthomonas, Erwinia, Caulobacter, Serratia, Arthrobacter, Micrococcus, Burkholderia, Flavobacterium, Chromobacterium, Agrobacterium, Hyphomicrobium, and Bacillus sp., etc., appears as a cost-effective, sustainable, and organic method [17]. It offers numerous advantages over chemical fungicides [18][19][20][21][22] as they are eco-friendly, biodegradable in nature, and safe to the environment, human health, and useful soil rhizobia [19].…”

Rice is a crop that is consumed as a staple food by the majority of the people in the world and therefore failure in rice crops, due to any reason, poses a severe threat of starvation. Rice blast, caused by a fungus Pyricularia oryzae, has been ranked among the most threatening plant diseases of rice and it is found wherever rice is grown. All of the rice blast disease management strategies employed so far have had limited success and rice blast has never been eliminated from rice fields. Hence, there is a need to look for the best remedy in terms of effectiveness, sustainability, and organic nature of the method. This study was aimed at determining the plant growth-promoting and fungicidal effects of a mixture of Piper caninum and Piper betle var. Nigra leaves extracts and rhizobacteria. Gas chromatography–mass spectrophotometry (GC-MS) analysis of a mixture of leaves extracts of these plants revealed the presence of new bioactive compounds such as alpha.-gurjunene, gamma.-terpinene, and ethyl 5-formyl 3-(2-ethoxycarbonyl) in a mixture of leaves extracts of P. caninum and P. betle var. Nigra. The mixture of these extracts reduced the intensity of blast disease, inhibited P. oryzae, and improved the growth, yield, and quality of Bali rice. All treatments comprising of different concentrations of a mixture of leaves extracts of P. caninum and P. betle var. Nigra plus rhizobacteria exhibited biocontrol and bioefficacy. However, a 2% concentration of a mixture of these leaves extracts with plant growth-promoting rhizobacteria (PGPR) exhibited potent inhibition of growth of P. oryzae, a significant reduction in the intensity of blast disease, and a maximum increase in growth, yield, and quality of Bali rice. In the 15th week, the intensity of blast disease decreased from 80.18% to 7.90%. The mixture of leaves extract + PGPR also improved the height of the plant, the number of tillers, number of leaves, number of grains per panicle, number of heads per panicle, and the full-grain weight per clump. Applications of various concentrations of a mixture of leaves extracts + PGPR resulted in improvement in the potential yield of rice, however, the application of 2% extracts + PGPR gave the highest potential yield of 5.61 tha−1 compared to the low yields in the control and other treatments. The high grain yield observed with the treatment was caused by the low intensity of blast disease. This treatment also strengthened the stem and prevented the drooping of the plant and improved the quality of rice grain.

Rice (Oryza sativa L) is an economically important carbohydrate-producing plant that ranks second only to wheat. In Indonesia, Malaysia, the Philippines, and several other countries, rice is used as a staple food source. The commodity projection is expected in the coming years to grow to reach 70 percent. Blast disease is known as one of the main obstacles in rice cultivation today. Recommended control alternative to the disease was through the utilization of economically beneficial and environmentally friendly resistant varieties. The study used six varieties tested on different cultivated land and designed using a split plot experiment. The results showed that the resistance of the six varieties of rice to blast disease, with the criteria from susceptible to resistance was: Kabir07 (5%) and IPB8G (3%) classified as susceptible, followed by IPB9G 1.8% (moderate resistance), Inpari32 1.8% (moderate resistant), Fas Memeye 1.8% (moderate resistant), and IPB3S 1.2% (resistant). The study found that irrigated rice fields had a higher severity of blast disease than rain-fed rice fields. Keywords: blast disease, resistant variety, rice fields irrigated, rice rainfed lowland ABSTRAK Padi (Oryza sativa L) adalah tanaman penghasil karbohidrat penting secara ekonomi yang menempati peringkat kedua setelah gandum. Di Indonesia, Malaysia, Filipina, dan beberapa negara lain, padi digunakan sebagai sumber makanan pokok. Proyeksi komoditas tersebut diharapkan pada tahun-tahun mendatang tumbuh mencapai 70 persen. Penyakit blas dikenal sebagai salah satu kendala utama dalam budidaya padi saat ini. Alternatif yang direkomendasikan untuk pengendalian terhadap penyakit ini adalah melalui varietas tahan yang bermanfaat secara ekonomi dan ramah lingkungan. Penelitian bertujuan mengevaluasi ketahanan enam varietas padi pada lahan padi sawah dan sawah tadah hujan terhadap penyakit blas. Penelitian ini menggunakan enam varietas diuji pada lahan budidaya yang berbeda dan dirancang menggunakan percobaan petak terpisah. Hasil penelitian menunjukkan bahwa tingkat ketahanan keenam varietas padi terhadap penyakit blas, dengan kriteria dari rentan sampai tahan adalah: Kabir07 (5%) dan IPB8G (3%) tergolong rentan, diikuti oleh IPB9G 1,8% (moderat tahan), Inpari32 1,8% (moderat tahan), Fas Memeye 1,8% (moderat tahan), dan IPB3S 1,2% (tahan). Ditemukan bahwa lahan sawah irigasi memiliki keparahan penyakit blas lebih tinggi dibandingkan dengan sawah tadah hujan. Kata kunci: penyakit blas, sawah tadah hujan, sawah irigasi, varietas resisten
