    D Rogor 30 EC@ 500 ml/ ha spray Correct Answer Incorrect Answer

    Solution

    • White grub  is a common pest in maize, and it can be effectively controlled by:
      1. Phorate 10% granules @15 kg/ha  mixed in the soil before sowing.
      2. Carbofuran 3% granules @30 kg/ha  mixed in the soil before sowing.
    Both  Phorate  and  Carbofuran  are systemic insecticides that provide effective control against white grubs when applied to the soil before sowing.
    • Rogor 30 EC  (an organophosphate insecticide) is not typically used for soil application against white grubs; it is more commonly used as a foliar spray for other pests.
