With reference to Neem tree, consider the following statements: 1. Neem oil can be used as a pesticide to control the proliferation of some species of insects and mites. 2. Neem seeds are used in the manufacture of biofuels and hospital detergents. 3. Neem oil has applications in pharmaceutical industry. Which of the statements given above is/are correct?

Neem (Azadirachta indica) is a tree with significant medicinal and commercial value. Let's evaluate the given statements: Neem oil can be used as a pesticide to control the proliferation of some species of insects and mites: This statement is correct. Neem oil contains active compounds like azadirachtin, which acts as a natural insecticide, repellent, and growth disruptor for a wide range of pests, making it a popular organic pesticide. Neem seeds are used in the manufacture of biofuels and hospital detergents: This statement is partially correct but primarily misleading regarding 'hospital detergents.' Neem oil, extracted from seeds, has potential as a biodiesel feedstock. However, while neem extracts are used in various soaps and personal care products due to their antiseptic properties, their direct widespread use in the manufacture of 'hospital detergents' as a primary input is not commonly recognized. The claim regarding 'hospital detergents' makes this statement largely incorrect in its entirety. Neem oil has applications in pharmaceutical industry: This statement is correct. Neem and its derivatives have been extensively studied and used in traditional medicine systems like Ayurveda and Unani. Neem oil is known for its anti-inflammatory, antiseptic, antifungal, antibacterial, and antiviral properties, making it valuable in the pharmaceutical industry for various formulations, including skin preparations, dental products, and internal medications. Therefore, statements 1 and 3 are correct.
