One of the alternative control efforts for Southern corn leaf blight (SCLB) disease is using biological agents and certain chemicals as elicitors to induce systemic resistance through increasing secondary metabolites. This study aims to evaluate several types of biological and chemical exogenous elicitors in inducing plant systemic resistance to SCLB disease caused by Bipolaris maydis and their effect on corn growth and yield. Testing was carried out under field conditions with planting spreader rows as inoculum source plants which were planted around the experimental block. This experiment was set up in a randomized block design consisting of eight elicitor treatments, one synthetic fungicide as a control (-), and sterile distilled water as control (+). AUDPC analysis based on disease severity showed that B. cereus strain J6, Chitin, and Chitosan could significantly suppress the SCLB disease progression in the field with the lowest AUDPC values, namely 1230, 1255, and 1255, respectively, and the highest protection index values of 30.31, 28.90, and 30.88%, respectively. Suppression of the SCLB disease progression was related to increasing plant resistance levels through increasing protein and phenolic content. Correlation analysis showed that B. cereus strain J6, Chitin, and Chitosan had a very strong positive correlation with the protection index value. Besides inducing plant resistance, elicitor treatments significantly affected maximum growth potential and plant height variables. Elicitor materials play a beneficial role in protecting corn occurrence by activating the induced systemic resistance system and inducing plant growth.

Plant diseases in maize are still one of the limiting factors in efforts to increase maize production. The aims of this study were: (1) to obtain populations, lines, and candidate hybrid varieties that were resistant to downy mildew (Peronosclerospora spp.), maydis leaf blight (Bipolaris maydis), rust (Puccinia sp.), and bacterial stalk rot (Dikeya sp.); (2) to identify the causative pathogen using 16s rDNA analysis. In this study, a number of lines/populations of candidate varieties were tested against downy mildew, maydis leaf blight, rust, and stalk rot. The test results showed that all tested hybrid candidates showed resistance to downy mildew even JHD 03 showed a very resistant reaction. The average downy mildew attack ranged from 0.0-10.7%. All of the hybrid candidates tested showed a moderately resistant reaction to maydis leaf blight with an average attack percentage ranging from 18.0-24.7%. All tested hybrid candidates showed a sensitive to very sensitive reaction to rust disease with an average attack percentage ranging from 31.3-68.7%. There were five hybrid maize lines showing very resistant to moderately resistant to bacterial stem rot disease with an average attack percentage ranging from 4.67-24%.

“…To determine the disease's progress in each material tested, data of the disease severity were plotted against the time of observation to get the disease development curve. For statistical analysis, the area under the disease development curve (Area Under Diseases Progress Curve, AUDPC) is calculated using the following formula (Mehmood et al 2016):…”

Foxtail millet has the potential to be developed as a healthier food alternative because of its high nutritional value. Disease such as leaf blight caused by Bipolaris setariae is one of the limiting factors in Foxtail millet productivity. One of the efforts to control the pathogen is by utilizing resistant varieties. In this study, two candidate varieties and two germplasm accessions were tested to determine the level of resistance to Bipolaris setariae leaf blight. The study was arranged based on a complete randomized design with six replications. Each test material was inoculated with the spore suspension at 4 WAP. Disease intensity was observed based on the disease scoring at 7, 9, and 11 WAP. AUDPC value is calculated based on the intensity of the attack at a particular observation time. Grain weight was recorded and statistically analyzed. The two candidate varieties of foxtail millet Pagamogo and Tedamude from Nagekeo Regency showed a moderately resistant response to leaf blight and had the lowest AUDPC values of 907.69 and 912.31. The highest increase in AUDPC values was observed in the initial observation period at 0-49 DAP.
