Many years of planting fruits and vegetables, many farmers are aware of the hazards of using pesticides in large quantities. They also know that agricultural products with excessive pesticide residues have almost no market. Therefore, many regions have begun to insist on not using pesticides to kill insects. Instead, they use electric shocks. Pest killing lamp kills insects. Electric shock insecticidal lamp is a highly recommended insecticide tool in the current development of green agriculture. The insect lamp is energy-saving and environmentally friendly. After application, the vegetable produced at the base is green and healthy, and it is very popular with the market. Therefore, the current For agricultural development, electric shock lamp is more popular among farmers. As the name suggests, electric shock killing lamps use electric shock to kill pests. It is a new type of control technology that utilizes the characteristics of insect pests such as phototaxis and wave-like waves to trap and kill pests. There are many types of electric shock insecticidal lamps, which can trap and kill nearly 20 kinds of vegetable pests of the order <Lepidoptera, Coleoptera, Orthoptera, and Homoptera. They are suitable for crop planting bases such as vegetable gardens, orchards, and tea gardens. The electric shock insecticidal lamp not only has a strong trapping ability, but also has a good prevention and control effect, and is convenient in operation, simple in management, and energy-saving and environmentally friendly. Killing pests can also feed chickens, which is a good safe high protein feed. At present, in the process of vigorously promoting green, pollution-free agriculture and vigorously developing the pollution-free fruit and vegetable industry, electric shock-killing lamp has become an important technology for reducing the use of chemical pesticides and effectively solving the problem of fruit and vegetable pests. The application of this technology has played an important role in assisting precision-oriented industrial parks for poverty alleviation and improving the quality of quality fruits and vegetables. Not only does it save farmers a large amount of medication costs each year, it also maximizes the ecological balance, reduces the labor intensity of farmers, makes food more green and pollution-free, and shows good ecological, economic and social benefits. As a result of the promotion of farmers’ income, farmers are very supportive of this change in the method of insecticide. Areas that have not yet been used are actively bringing in new technologies for plant protection.

Castings are used virtually every where. The transport sector and heavy equipment is the predominant consumer (for farming, construction and mining) taking up over 50% of castings produced.
A sector wise casting consumption is given below which highlights the importance of casting in any industrial set up.
• Heavy equipment like machine leads, ship`s propeller, etc. can be thrown easily in the required size rather than fabricating them by joining several small pieces.
• Casting is best suited for composite components requiring different properties in various direction. These are made by incorporating preferable inserts in a casting. For example, aluminum conductors into slots in iron armature for electric motors, wear resistant skins onto shock resistant components.
