Why Choose ChemShop Glyphosate Weed Killer?

• NZ Trusted: Manufactured and distributed locally for New Zealand conditions.

Technical Specifications & Safety

Directions for Use

To achieve the best results and ensure environmental safety, follow these application guidelines:

1. Preparation: Dilute with clean water according to the specific weed type (typically 10ml to 15ml per 1L of water for general weeding).
2. Application: Apply using a spray unit, ensuring even coverage of the foliage.
3. Conditions: Apply to actively growing plants. Avoid application during windy conditions to prevent spray drift onto non-target plants.
4. Weather: Do not apply if rain is expected within 6 hours of treatment.
5. Safety: Always wear appropriate PPE (gloves and eye protection). If the product is splashed in eyes, wash out immediately with plenty of water.

Frequently Asked Questions

Is this weed killer safe for pets and children?

Once the spray has completely dried on the leaf surface, the area is generally safe for pets and children to re-enter. We recommend keeping animals away during the actual application process.

How long does it take to see results?

Visible effects (yellowing or wilting) usually appear within 7 to 10 days for annual weeds, while tougher perennial weeds may take up to 2-3 weeks depending on the weather.

Can I replant after using this herbicide?

Yes. Because this is a non-residual herbicide, it breaks down in the soil. You can typically replant ornamentals or sow lawn seed 7 days after application.
