Tempra Nutgrass Herbicide 500g | Halosulfuron Sedge Killer

Product Description

TEMPRA (SureFire Tempra 750 WG) is a selective herbicide containing 750 g/kg halosulfuron-methyl (Caution poison), in 25 g, 100 g and 500 g packs. The label lists nutgrass in sugar cane, corn, sorghum and irrigated cotton (shielded or directed application), and Mullumbimby couch and nutgrass in established turf of the species named on the label: bent grass, buffalo grass, carpet grass, couch and couch hybrids, Durban grass, kikuyu, perennial ryegrass, Queensland blue couch and tall fescue. The label rate is 65 to 130 g per hectare, or 1.3 g per 100 square metres, with a wetter. Home gardens, ornamentals and vegetables are not listed.

Damage and restraints. The label warns that use on newly seeded, sodded or sprigged turf that is not well established may cause damage or delayed establishment, as may use on turf weakened by weather or by scarifying, coring, aerating or top-dressing. Avoid spraying non-target vegetation. Do not let spray drift onto nearby susceptible plants or crops: spray or drift that touches cotton may cause severe injury. Do not apply more than 200 g per hectare per season, after the onset of frosts, through any irrigation system, or if heavy rain is expected within 48 hours. Delay mowing for 2 days after treatment. Irrigation or rain within 2 hours of application reduces control.

Before you buy. The label says it is harmful if swallowed and that dust irritates the eyes; avoid contact with eyes and skin and wash hands after use. It is very highly toxic to duckweed: do not contaminate dams, rivers or streams with the product or the used container. Keep people and pets off treated areas until the spray has dried.

How to Apply:

Apply to actively growing weeds:
Nutgrass: Ensure at least 5 cm of new leaf growth.

Effects begin in 7–10 days, with full results in 4–6 weeks.

Important Limits:

Max Application: 200 g/ha per season.
Avoid use after frost starts or before heavy rain (within 48 hours).
Only one Group B herbicide application per season to prevent resistance.
Do not apply through irrigation systems.

Do not mix with paraquat or ametryn—they reduce effectiveness.

Do not apply 7 days before or 3 days after using this herbicide.

Corn/Maize, Sorghum, Sugarcane: 2 months
Wheat: 3 months
Cotton: 4 months

Frequently asked questions

What is the difference between a selective and a non-selective herbicide?

A selective herbicide kills target weeds while leaving desirable plants unharmed - for example, a lawn-safe product that removes bindii and clover from buffalo or couch without damaging the turf. A non-selective herbicide such as glyphosate kills almost any green plant it contacts, so it is used for driveways, fence lines, garden-bed prep and total vegetation control, never on lawns.

What is a pre-emergent herbicide and when do I apply it?

A pre-emergent creates a barrier in the top layer of soil that stops weed seeds from establishing as they germinate. It does not control weeds that are already growing. Apply it before the target weed germinates - late summer to early autumn for winter grass, and early spring for summer grasses like crabgrass and crowsfoot - then water it in.

Will herbicide damage my lawn?

Only if you use the wrong type. Non-selective herbicides (glyphosate) will kill or badly damage turf. Selective lawn herbicides are formulated to be safe on common Australian turf at label rates, but tolerance varies by grass - buffalo is the most sensitive - so always check the label lists your turf type before spraying.
