The Jackfruit (Artocarpus heterophyllus L.) is well-known as “poor man’s food” fruit in Bangladesh. It is widely consumed by most of the rural people and it is the national fruit of Bangladesh. The main aim of this review is to document the medicinal significance of jackfruit (Artocarpus heterophyllus L.), major parts and uses of the jackfruit in Bangladesh. This article was based on mostly a literature review. All parts of the fruit and plant are used as human food, animal feed and wood source for furniture. Although jackfruit is the main fruit of the tree, it is used as furniture for its beautiful texture and wood color. Jackfruit contains anti-bacterial, anti-diabetic, anti-oxidant, anti-inflammatory and anti-helminthic properties. The fruit is rich in carbohydrates, minerals, carboxylic acids, dietary fiber, vitamins and minerals. The seed is rich in manganese, magnesium, potassium, calcium iron and lectins and thus meets up nutritional requirements for the rural people. The present study attempted to review the medicinal importance, health-promoting effects of jackfruit and seeds with special emphasis on their applications in the food.

Irrational applications of insecticides on vegetable crops are very common in Bangladesh, resulting in harmful consequences for the environment and human health. Therefore, a study was conducted to evaluate the efficacy of biological and botanical insecticides on okra shoot and fruit borer grown in open fields. Four insecticides were used in this study, namely Bacillus thuringiensis (Bt), Spinosad 45 SC, Abamectin 1.8 EC, and Azadirachtin 1% EC an untreated control. The experiment used a randomized complete block design (RCBD) with three replications. The results showed that the rate of shoot infestation was the lowest in the Spinosad-treated plot (3.80%), and the highest was in the control (20.67%). The lowest fruit infestation (3.56%) was recorded in the treated plot of Spinosad. The rate of reduction of fruit infestation over control was 80.69, 60.14, 56.45, and 55.58% in the plots treated with Spinosad, Bt, Azadirachtin, and Abamectin, respectively. Consequently, the Spinosad-treated plot attained the highest yield (8.65 t ha−1), which was followed by the plots treated with Azadirachtin (6.74 t ha−1), Bt (6.28 t ha−1), and Abamectin (6.12 t ha−1). The highest net return and benefit–cost ratio (BCR) were 542.36 US$ and 2.64, obtained respectively from the Spinosad-treated plot. The second highest BCR (1.70) was obtained from the Azadiratin-treated plot, and the lowest BCR (1.18) was recorded in the Abamectin-treated plot. Therefore, the studied insect management practices could be incorporated to attain higher yields and economic benefits for growing okra in Bangladesh.

At present food-security and sustainability is a burning issue all over the world. Many indigenous food crops of Bangladesh which promises to ameliorate fruit nutritional food demand and they have the good possibility to develop the world market. Country bean is one of the most important vegetables and pulse crop which have tremendous nutritional value and this crop is cultivated round of the year. Insects, diseases, weeds and soil nutrient management were found as the major barriers for country bean production. Lack of technical knowledge and improper crop management approaches were observed to bean cultivation. To optimize the higher yield of country bean, it had to use less hazardous insecticides, fungicides, biocides, herbicides, and balanced fertilizer and bio-fertilizers in crop management practice. This review paper examined the problems and solutions for the country bean production.

Chrysanthemum is a floricultural, ornamental and medicinal plant with tremendous income cash crop which is cultivated chiefly in winter. The crop charity as nerve sedative, anti-oxidant, anti-inflammatory, anti-mutagenic, anti-microbial, anti-fungal, anti-angiogenic, anti-atherosclerosis and nematocidal goods. Chrysanthemum has been used for hundreds of years in manufacturing medicine. It is used to treat respiratory complications, high blood pressure, and hyperthyroidism and reduce inflammation. Leaves remedies for colds, headaches, bronchitis, rheumatism, and swellings. The plant has aesthetic significance as well. Nevertheless, outbreaks of pests and diseases have hold back Chrysanthemum cultivation in Bangladesh. Insect pest damages the plant directly by sucking cell sap and indirectly spread out of virus diseases as act of vector. Aphid resistance variety might be the effective tool for successful production of chrysanthemum plant. Sustainable crop disease management for Chrysanthemum needs a multitude of consideration of the impacts of management methods on economics, sociology and ecology by wholly understanding the mechanisms of crop disease epidemics and the functioning of normal agroecosystems. The findings of this study present clear insights into efforts that will encourage farmers to adopt effective and ecological methods of pest and disease management for successful chrysanthemum production in Bangladesh.

Purpose: Country bean (Lablab purpureus L.) is an important pulse crop consumed as a vegetable in the central and south-western regions of Bangladesh after eggplant and tomato. It promises to ameliorate nutritional demand from vegetables and has an excellent possibility for the world market. But the production is hampered due to infection of several diseases in field conditions.Research Method: This study was undertaken based on secondary data of existing literature from Bangladesh and other parts of the world. So far, many research works were done on this issue but those were not available to the policymakers, extension workers, and public in a systematic manner to date. Findings:In this paper, we tried to bring forth different aspects of phytopathological problems of country bean. It usually undergoes stresses from different soilborne to seed-borne pathogens and expresses symptoms from the seedling stage to maturity. Crop protection largely depends on the integration of host plants, seeds, agronomic practices, environmental footprints, and the use of appropriate agrochemicals based on the epidemiology of target pathogens. Here, we have also described effective management strategies against respective pathogens of the diverse category. These microorganisms attack at different stages of crop growth and can affect the host plants enormously to cause maximum yield loss. Research Limitations:The study focused on the management of country bean diseases based on biological and chemical approaches. It presents limited information on specific technologies in different agroecological zones.Originality/ Value: This study identified research gaps among Bangladesh and other countries. It also provides information to combat country bean diseases to the economic threshold level for ensuring sustainable crop yield.

Black pepper ( Piper nigrum L.) is a popular spice that is grown as tropical and subtropical plant throughout the world. The leaf, flower, fruit, and root are the most important elements of the plant. Asexual or vegetative propagation is becoming highly popular, although the sexual approach is still used for pepper vine cultivation. For mass production of the pepper plant, in vitro culture is also used. The bioactive components contained in them are extremely important because of their therapeutic potential against a number of diseases. They are usually classed as functional foods because, in addition to providing basic nutrition, provide physiological benefits and help to avoid chronic illness. The main component of black pepper is piperine. It has a complex phyto-chemistry includes: Volatile oil, alkaloids, and oleoresins. Because of its free-radical scavenging properties, black pepper and its active components can be prevention and control of tumor growth. Piperine, which can bind and inhibit the SARS-CoV-2 virus that causes the sickness, is present in black pepper and has antibacterial and antiviral effects. Piperine, a key alkaloid component of black pepper, it also helps to cognitive brain function, nutritional absorption, and gastrointestinal health. Black pepper is known as the “King of Spices” as well as the “King of Medicinal Agents,” since it includes a wide variety of bioactive compounds with nutraceutical and pharmacological applications. An overview of the most common applications for black pepper, along with a strong evidence is present in this review.
