> Technical Sheet

The grub specialist
that performs even
in dry conditions

MERIDIAN Turf Insecticide achieves the perfect balance of solubility and soil binding.
Once correctly applied and washed in, this versatile insecticide has great bioavailability
ensuring season long grub control in situations where irrigation is irregular.

What MERIDIAN offers you:
• Flexible rate range with residual control of up to 3 months
• Superior bioavailability in soil at lower soil moisture levels compared to imidacloprid
making it a more consistent performer throughout the season
• A versatile option to use on sporting fields, parks, ovals, fairways and other
situations with irregular irrigation

SpraySURE | Accuracy and Performance

To achieve great results, accurate application is important.

| Target | Syngenta Nozzle | Optimal Water Rate | Optimal Pressure Range |
| :--- | :--- | :--- | :--- |
| Root and soil So | XC 08 | > 500 L/ha | 2 to 4 bar |

MERIDIAN is particularly active against the 1st and 2nd instar larvae of the most destructive turf infesting
grub species. The window for application should thus be positioned around the peak egg laying period by
adult beetles. This timing can be monitored by the increasing activity of adult beetles, usually during spring
and early summer.

Example: African Black Beetle egg laying traditionally peaks around October whereas that of the Argentinian
Scarab peaks around November to early December. An application at 1.2 kg/ha before the peak occurs
should be sufficient to ensure high levels of grub control for up to 3 months.
