Crux - Thiamethoxam 25% WG - Nichino
Nichino Crux Thiamethoxam 25% WG Insecticide
Nichino Crux is a systemic insecticide containing Thiamethoxam 25% WG. Thiamethoxam is a neonicotinoid in IRAC Group 4A that acts on insect nicotinic acetylcholine receptors.
The verified Indian use table contains crop-specific foliar and soil-drench rows for selected sucking pests and rice pests. Use only the crop, pest, method, rate, water volume and waiting period on the current Crux pack.
Important: There is no universal grams-per-litre or tank dose. Keep foliar and soil-drench rates separate, and do not treat another Group 4A product as a different-mode rotation.
Item description
Nichino Crux Thiamethoxam 25% WG Insecticide - Product Overview
Nichino Crux is a systemic insecticide containing Thiamethoxam 25% WG. It is a neonicotinoid insecticide in IRAC Group 4A, formulated as water-dispersible granules.
The verified Indian use table includes specific foliar and soil-drench applications against selected pests in rice, cotton, okra, mango, wheat, mustard, tomato, brinjal, tea, potato, citrus and cumin. Every crop and method has its own rate, dilution water and waiting period. The current physical Crux label is the final authority for the pack being used.

How Crux Works
Thiamethoxam acts on insect nicotinic acetylcholine receptors and disrupts normal nerve signalling in susceptible pests. Nichino describes Crux as systemic and translocated within the plant. The IRAC code is a resistance-management classification; it does not authorise an unlisted crop, pest, method, dose or spray interval.
Another Thiamethoxam product remains IRAC Group 4A and is a same-active substitute, not a different-mode rotation. Select any rotation product only after checking its own crop, pest, rate, timing, PHI and restrictions. Do not interpret a recommendation card as permission to tank-mix or co-apply products.

Method-Specific Application Guidance
- Crop and pest: Use Crux only on a crop-and-pest combination listed on the current physical label.
- Measurement: Measure the crop-specific formulation rate accurately. Do not replace it with a universal grams-per-litre, pump or tank dose.
- Foliar and drench uses: Keep the potato foliar and soil-drench rows separate. Rice-nursery and tomato soil-drench rates are also method-specific.
- Tomato foliar: The Government table states 2-3 sprays at 10-15 day intervals according to pest intensity after the first spray at initial whitefly appearance.
- Brinjal and citrus foliar: The stated repeat interval is 15-21 days, with 2-3 sprays according to pest intensity.
- Tomato soil drench: Apply to the root zone after transplanting once during the crop season.
- Mixing: Do not add another insecticide, fungicide, herbicide, fertilizer or adjuvant unless the current Crux label expressly permits that mixture.
Frequently Asked Questions
1. What is the active ingredient in Crux?
Crux contains Thiamethoxam 25% WG, a systemic neonicotinoid insecticide in IRAC Group 4A.
2. What is the correct dose per acre?
There is no single universal dose. Nichino's verified rows range from 20 g/acre for wheat aphid to method-specific higher rates such as 800 g/acre for rice-nursery soil drenching. Select the exact crop, pest and method on the current pack.
3. Can Crux be used as a soil drench?
Only the verified potato, rice-nursery and tomato soil-drench rows may be presented here. Do not convert another crop's foliar rate into a drench.
4. What waiting period should be followed?
Follow the crop-specific PHI in the table and the current physical pack. The verified periods range from 3 days for brinjal to 86 days for rice-nursery soil drenching.
5. Is another Thiamethoxam product a resistance rotation?
No. Another Thiamethoxam product remains IRAC Group 4A. A different-mode option must have its own label-approved crop, pest, timing and restrictions, and a recommendation never implies tank mixing.
Safety & Label Compliance
Read and follow the current physical Crux label and leaflet before use. Wear the personal protective equipment and observe the re-entry interval stated on that pack. Keep the product in its original closed container away from children, animals, food and feed. Avoid exposure and contamination of water or non-target areas. If exposure or illness occurs, stop work and seek medical advice with the label available. Dispose of the empty container exactly as the label and local rules direct.
