Why Pest & Weed Control is Essential for Healthy LawnsAustralian lawns face unique challenges: hot summers, erratic rainfall, and a wide range of pests and weeds that thrive in different seasons. Lawn Armyworm, curl grubs, black beetle larvae, bindii, clover, and winter grass can undo months of lawn care overnight. That’s why having the right control products is essential. Unlike quick-fix sprays you might find in hardware stores, the professional-grade products stocked by Plant Doctor, including Acelepryn, Acelepryn GR, Barricade, Estate, and Monument Liquid, provide long-lasting protection and are widely trusted by turf managers, golf courses, councils, and home lawn enthusiasts alike.
This guide breaks down each product, what it controls, when to use it, and why it’s a smarter investment for your lawn.
Acelepryn is a Group 28 anthranilic diamide insecticide containing 200 g/L chlorantraniliprole (SC formulation). It is widely regarded as the gold standard in armyworm and curl grub control because of its long-lasting performance and exceptional turf safety.
| Acelepryn Liquid vs Acelepryn GR | When to Apply Acelepryn in Australia | |
|---|---|---|
 |
Acelepryn SC (liquid suspension concentrate): Best applied as a preventative in mid-September when adult beetles and moths begin activity. Offers strong residual control. |
|
 |
Acelepryn GR (granule formulation): A convenient no-spray option. Easy to spread, especially in schools, parks, or residential areas. Provides the same long residual protection. |
Barricade is a Group 3 pre-emergent herbicide (480 g/L Prodiamine) that provides up to 6 months of weed prevention. Unlike post-emergent sprays that kill existing weeds, Barricade stops weeds before they even germinate.
