<p>Chili (Capsicum annuum L.) is a vegetable commodity with high economic value which is widely cultivated by farmers in Indonesia. One of the obstacles faced in chili cultivation is stem rot disease. This study aimed to identify the pathogens that caused stem rot in chili plants obtained from one location in Sindangjaya Village, Cipanas District, Cianjur Regency, West Java Province based on morphological and molecular analyses. Pathogen identification was performed with morphological and molecular approaches. The morphological characters observed included colony shape, sporangium diameter, and mating type. The pathogenicity of the isolates was assayed by inoculating chili stems aged 40 days. Molecular identification was carried out using two pairs of primers for ITS regions and TEF-1 gene. Based on the results of morphological and molecular identification, as well as pathogenicity tests, it was confirmed that Phytophthora capsici pathogen was the causal agent of stem rot in chili plants collected from Sindangjaya Village. Further study is needed to determine the spread of the disease, damage, and yield loss caused by stem rot disease, as well as how to prevent and control the disease.</p>

Salicylic acid (SA) is endogenous naturally occurring plant growth hormone acting as an important signaling molecule adds tolerance against abiotic stress. A field experiment was conducted to assess the efficacy of exogenous application of SA on growth, yield and storage performances of onion during Rabi 2012-13, 2013-14 and 2014-15. The experiment was comprised of 6 different treatments of SA including control. Exogenous applications of all SA treatments significantly influenced plant growth and development. The treatment application of SA at 30 days after seed sowing and second spray at 30 days after transplanting and third spray at 60 days after transplanting performed superior in terms of growth, development and yield. Exogenous application of SA significantly influenced on thrips population and stemphylium blight disease incidence and intensity. The results also revealed that SA partially involved in post-harvest management of onion. SAARC J. Agri., 18(1):39-49 (2020)

A study on lentil (Lens culinaris Medik) was carried out at Rampur, Chitwan with different sowing dates under field conditions to assess the severity of Stemphylium blight disease severity and yield performance during two consecutive years 2012-2014. During 2012/013, lower (3.00) and higher disease severity (6.50) were recorded on lentil plants sown on November 6 and December 16, respectively. Early sown lentil resulted in higher yield (2025 kg/ha) followed by late shown one (1213 kg/ha). Similarly, trends of disease development were similar in succeeding year (2013/14). Lentil seed shown on November 1 had lower disease severity (3.50) and produced higher yield (962.50 kg/ha) compared to that were shown on later dates. Disease severity increased with the advancement of sowing date from November 1 to December 21 with decreased yields. Hence, over years, early shown lentil (November 1, 6 and 11) escaped the higher severity of Stemphylium blight with the increase in yield.Journal of the Institute of Agriculture and Animal Science.Vol. 33-34, 2015, Page: 129-136

Maize is one of the most important cereal crops in the world. It belongs to family, "Poaceae". It has wider adaptability under different agro-climatic conditions. Its productivity per unit area is very high, so it is called “queen of cereals” globally. Though, Crop has high food and economic value, its production is limited by many constraints including the diseases also. Maydis leaf blight (MLB) is found almost everywhere maize is grown. It is caused by fungus Helminthosporium maydis. This disease is highly destructive in hot, humid and tropical climates of the world. In present investigation field trial was conducted to evaluate the effect of Spacing and Nitrogen dosages thereby managing the disease. The layout of this field experiment was in split plot design and conducted for the year 2019 and 2020 Kharif comprising of spacing: 45x20 cm, 60x20 cm and 75x20 cm and nitrogen dosages: 120, 160, 200 and 240 kg/ha as treatment with three replications. Results show that during 2019, the lowest PDI was obtained with the spacing of S3 (75x20 cm), which was significantly superior to all the spacing thereby reducing disease severity. The PDI was significantly influenced by nitrogen levels too. Lowest PDI (54.06 %) was obtained with the N3 (200 kg/ha), significantly superior to N2 and N1 levels of nitrogen fertilizer. There was also a significant interaction between spacing and nitrogen levels. Similar results were obtained during 2020 and for pool data that has also been calculated for the year Kharif 2019-2020. During the year, 2019 and 2020 grain yield was significantly influenced by spacing and nitrogen level too but the interaction was not significant.
