Frequently Asked Questions

Do I need a licence to buy or use these?
Most products here are unrestricted and can be bought and used by anyone following the label. A few are restricted chemical products that need a chemical user permit in some states – those are flagged on the product page. If in doubt, check the poison schedule on the label.

How do I work out the mixing rate?
The label gives a rate either per 100 L of water (a concentration) or per hectare or per 100 square metres (an area rate). For a knapsack, work out the area one tank will cover, then scale the per-area rate to that tank volume. Calibrate the sprayer before you start.

Why do the same chemicals come under different brand names?
Once an active ingredient comes off patent, several companies register their own version. A generic glyphosate 360 and a big-brand glyphosate 360 are the same active at the same strength – the difference is formulation quality, surfactant load and price.

How should I store and dispose of farm chemicals?
Keep them in the original labelled container, closed, in a locked ventilated store away from food, seed and fertiliser. Triple-rinse empty containers and dispose of them through drumMUSTER or as the label directs. Never pour leftover spray down a drain or into a watercourse.

What is in the Farm Chemicals category?
Trade and commercial-strength herbicides, insecticides, spray adjuvants and marker dyes, sized from 1 L home packs to 20 L drums. Most are registered agvet chemicals sold for use strictly as directed on the label.
