Abstract

The use of salicylic acid as resistance inducers agents in several plants species was well known. Salicylic acid has been believed to play an important role in inducing resistance against some pathogen. This research was aimed to study the role and effectiveness of salicylic acid as inducers for the resistance of some rice variety against bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae. The experiment was arranged in completely randomized factorial design with three factors i.e. rice variety, salicylic acid, and pathotypes, each treatment was replicated three times. The results showed that salicylic acid could prolong the latent period of X. oryzae pv. oryzae pathotypes IV and VIII in paddy rice varieties Conde and Ciherang,  induce the resistance of rice varieties as well as reducing the rate of infection of the two mentioned pathotypes. Salicylic acid was also able to induce the resistance of Conde and Ciherang varieties in order to suppress area under disease progress curve (AUDPC)  of X. oryzae pv. oryzae pathotypes IV and VIII.

Abstract

Bacterial leaf damage or blight brought by bacteria Xanthomonas oryzae pv. oryzae (X. oryzae pv. oryzae) is considered as an extremely serious disease of rice worldwide, including Indonesia. Induced resistance using chemical and biological agents was considered as a method to control the disease. The objectives of this research were to analyze of endophytic bacteria (Lysinibacillus sphaericus/L.sphaericus) and salicylic acid as the inducers of rice resistance against X. oryzae pv. oryzae. This study used three-factorial incompletely randomized designs to study the effect of endophytic bacteria and salicylic acid on three varieties of rice. The results of the study showed that endophytic bacteria and salicylic acid induced rice resistance to X. oryzae pv. oryzae. This endophytic bacterium was also able to increase the plant height (AUPHGC), the number of tillers (AUNTGC), and the number of productive tillers. The application of salicylic acid at the concentrations of 10 mM was able to suppress the BLB disease and increased the number of tillers and 1000-grain weight. The result of study showed that the endophytic bacteria and salicylic acid could induce resistance of rice varities against BLB disease and increased the number of productive tillers.

Abstract

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.

Abstract

Non-communicable diseases (NCDs) are one of the main causes of death worldwide. In 2016, 73% of deaths in Indonesia were estimated to be due to NCDs, of which 35% were caused by cardiovascular disease, 12% cancer, 6% acute respiration, 6% diabetes, and 15% other NCDs (World Health Organization, 2018). In Indonesia, the results of Riskesdas 2018 show that the prevalence of the population with high blood pressure is 34.11%. The prevalence of high blood pressure in women (36.85%) was higher than that of men (31.34%). The prevalence in urban areas is slightly higher (34.43%) than in rural areas (33.72%). Control of Non-Communicable Diseases (NCDs) begins with early detection of risk factors. Early detection of Non-Communicable Diseases (NCDs) that can be done in the form of measuring blood pressure, detecting blood sugar, cholesterol and uric acid levels, measuring height and weight, and abdominal circumference. The purpose of holding free screenings as one of the priority programs for Real Work Class is to provide services as well as provide counseling about the importance of early detection of risk factors for Non-Communicable Diseases (NCDs). As a result of the dedication carried out by many people who were enthusiastic about participating in this free screening. The final result expected from the implementing team is that the community will increase their awareness to carry out early detection of NCDs risk factors at the puskesmas once a month, especially for people who have the final result will be at risk of contracting non-communicable diseases.
