Stock Level:
In Stock 6+


A powerful 570 g/L glyphosate formulation, Roundup ULTRA® MAX is the latest in Roundup technology, offering advanced performance and flexibility. Made to the highest quality standards, enhanced performance includes more comprehensive weed controlling capability, greater translocation qualities, and rainfastness. Roundup ULTRA MAX is at the forefront of weed control.

Active ingredient: 570 g/L glyphosate (present as the potassium salt)

Use Case: Roundup ULTRA® MAX in Resistant Ryegrass

Independent trials run by Dr. Peter Boutsalis of Plant Science Consulting investigated the bioefficiency of two glyphosate formulations in controlling susceptible and glyphosate-resistant ryegrass biotypes.

Dr. Peter Boutsalis concluded that, “Roundup ULTRA® MAX exhibited superior control at lower - intermediate rates on susceptible and glyphosate resistant ryegrass biotypes compared to a Glyphosate 540 g/L formulation.”

Use Case: Roundup ULTRA® MAX in Resistant Sowthistle (Milkthishle)

Dr Peter Boutsalis, Plant Science Consulting, Adelaide, SA, investigated the bioefficiency of four glyphosate formulations including Roundup ULTRAMAX in controlling susceptible and glyphosate-resistant Sowthistle Biotypes.

In this trial on glyphosate Resistant Sowthistle, Roundup® UltraMAX exhibited up to 30% better control at 800g ai/ha over other formulations at the same g ai/ha. Percent control of Susceptible Sowthistle did not differ above 500g ai/ha across the four glyphosate formulations.

The report suggests differences in surfactant technology influences glyphosate performance on Resistant Sowthistle.

Stock Control & Pricing Breaks

Our webstore now indicates an approximate level of items in stock. This is indicated as quantity breaks as follows: 1+, 6+, 12+, 36+, 100+, 250+, 500+, 1000+, 2000+ and 3000+. For example: if we have 5 ARS Florist Scissors in stock this would display as 1+ — if there are 47 in stock it will indicate 36+. As another example: if we have 14,960 Fluted Tree Guards in stock this would indicate as 3000+. The quantity also indicates the number of items as described by the product description; so Florist Scissors are sold individually whereas the 10L Carton Tree Guard is sold in boxes of 150 – in the later case 100+ items refers to 100+ boxes of 150 (or over 15,000 Carton Tree Guards in stock).

Please note: our webstore stock levels are accurate to within the last hour; if you order an item that has since sold out, we will promptly notify you as to when your order will be fulfilled. Some items may be indicated as Special Order items or display a custom message as to when stock is due.

Pricing breaks: many items in our store display pricing breaks. The number of items indicated in pricing breaks can vary a lot between different products. Often with horticulture tools such as secatuers and loppers, the pricing breaks may relate to the number of items in a box or total number of items in a carton; so if you need several secateurs, and order per box or carton, you save more as we save time packing your order. Items such as tree guards, bamboo canes and hardwood stakes often have price breaks set to fill a standard palette size; thus savings or efficiency gains are made in the storage and transport of these items.
