“…1 (2019) significantly decreased by intercropping. Also, Galande and Simon (2019) demonstrated that intercropping onion with the vegetable reduced both total and marketable bulb yield. These results may be due to competition between sugar beet and onion plants for nutrient, water and solar radiation.…”

“…Spider plant (Chlorophytum comosum) was the most effective vegetable intercrop in reducing downy mildew severity by up to 21 % and purple blotch severity by 18%. Also, Galande and Simon (2019) demonstrated that legume intercrops were effective in reducing purple blotch on onion and found that French bean was the most effective legume intercrop in reducing purple blotch incidence by up to 49.1 %.…”

“…In Bangladesh, limited attempts have been made to find out suitable control measures for this disease in bulb production as well as seed production [14]- [16]. Furthermore, globally people are now very much aware of environmental deterioration due to the indiscriminate and enormous use of highly toxic chemicals.…”

Field research was conducted in the central research farm of Sher-e-Bangla Agricultural University (SAU), during the period from October 2020 to March 2021. The experiment was a layout with RCBD design to evaluate the effect of selected fungicides (Indofil, Mancer, and Ridomil Gold), micronutrients (Zinc, Boron, and Magnesium), and botanicals (neem and eucalyptus leave extract) on purple blotch complex of onion. Data were collected on percent disease incidence and percent disease index, the number of leaves per plant, leaf length, bulb diameter, bulb weight (fresh and dry), and yield. The local cultivar Faridpuri was used as a tested variety. Among the selected fungicides, Ridomil Gold gave a better result than other fungicides in controlling the percent disease incidence (52.67%) and percent disease index (49.00%) with the highest number of yield qualities per plant. In addition to this, the highest bulb diameter (18.23 cm), single bulb weight (47.98 g), fresh weight (3.16 Kg/plot), and dry weight (2.88Kg/plot) were also obtained in Ridomil Gold treated plots. This treatment also gave better yield performance (9.60 t ha-1) followed by Indofil (8.20 t ha-1) and Mancer (7.90 t ha-1), and increased yield by 54.34% over the control treatment. From the study, it was also found that among the micronutrients, boron gave more satisfactory results than botanicals.

“…According to Bambang and Khusnul (2014) , anthracnose can reduce crop yields ranging from 21-63% even to 100% if conditions support especially when wet, heavy rain, and humid. Porch blotch of onion caused by Alternaria porri is an important disease of onion worldwide (Glande and Simon 2019). The disease yields a loss of 30% (Everts and Lacy 1990).…”

Abstract. Safitri YA, Hasanah U, Salamiah, Samharinto, Pramudi MI. 2019. Distribution of major diseases of shallot in South Kalimantan, Indonesia. Asian J Agric 3: 33-40. Shallot is a vegetable crop with high economic value, but its productivity in Indonesia is still relatively low. One of the causes is due to attack of the diseases. The research was conducted from November 2017 to April 2018, with the purpose of studying the distribution of major diseases of shallots in South Kalimantan. It consisted of field, laboratory, and greenhouse research. Field research involved the survey of shallots’ extensive planting in eight villages of six districts in South Kalimantan, disease symptoms, the broad of attack, and the collection of secondary data. Laboratory research included the isolation and identification of the pathogen causing diseases. The greenhouse research was conducted to perform the Postulate Koch test. The research result showed that there were two major diseases of shallots, namely Moler and Anthracnose. Pathogen causing Moler disease (Fusarium oxysporum) attacked shallot plant in six districts (Tabalong, Balangan, Tanah Laut, Kotabaru, Tapin, and Banjarbaru) and pathogen causing Anthracnose disease (Colletotrichum sp) attacked shallot plant in five districts (Tabalong, Balangan, Tanah Laut, Kotabaru, and Tapin).
