Question

In India, as per the label claim, the nematicide Velum Prime is recommended for the management of
(A) Meloidogyne incognita in tomato
(B) Meloidogyne incognita in protected cultivation
(C) Root-knot and cyst nematodes in protected and field crops
(D) Meloidogyne incognita in tomato and cucumber. Choose the correct answer from the options given below:

• A. (A) and (D) only.
• B. (A) only.
• C. (B) only.
• D. (A), (B) and (D) only.

Hint:

Velum Prime (fluopyram) is a modern, low-toxicity nematicide that has largely replaced older, highly toxic carbamate and organophosphate nematicides for managing root-knot nematodes in vegetable crops.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Chemical nematicides must be registered with regulatory bodies, such as the Central Insecticides Board and Registration Committee (CIB&RC) in India, before they can be sold or applied.
These registrations specify the approved crops, target pests, dosages, and application methods.
These details are recorded as the official "label claims" for the product.

Step 2: Detailed Explanation:
Velum Prime is a systemic nematicide developed by Bayer CropScience.
Its active ingredient is fluopyram (34.48% SC), which is a pyridinyl-ethyl-benzamide compound.
It works by selectively inhibiting succinate dehydrogenase (Complex II) in the mitochondrial respiratory chain of nematodes, which blocks cellular energy production.
In India, the initial registration and approved label claims for Velum Prime focused on managing root-knot nematodes (Meloidogyne incognita).
The official label recommendations specify its use on:
- Tomato: For managing root-knot nematodes (Meloidogyne incognita).
- Cucumber: For managing root-knot nematodes (Meloidogyne incognita).
The product is applied through drip irrigation systems shortly after transplanting.
Thus, statements (A) ("Meloidogyne incognita in tomato") and (D) ("Meloidogyne incognita in tomato and cucumber") represent the approved label claims in India.

Step 3: Final Answer:
The approved label claims for Velum Prime in India are for tomato and cucumber.
This corresponds to (A) and (D) only, making Option 1 the correct choice.
