    Solution

    The infective stage of Rotylenchulus reniformis, a nematode commonly known as the reniform nematode, is the second-stage juvenile (J2). The J2 stage is the mobile, infective stage of the nematode that can penetrate and infect plant roots. Once inside the roots, the nematode establishes a feeding site, causing damage to the plant and affecting its growth.
