Every registered agro chemical carries a label, and that label is the single most useful piece of information you will get about the product. It is also the part most farmers skip. Before you open a bottle, it is worth five minutes of your time.

Start with the active ingredient and its concentration. Two products with different brand names can contain exactly the same active at the same strength — and knowing this is how you avoid paying twice for the same chemistry, and how you rotate between actives to slow down resistance.

Next, check the target crops and target pests. A product registered for maize is not automatically safe on tomatoes. A selective herbicide that spares one crop will damage another. If your crop is not on the label, that product is not for your field.

Then read the application rate and dilution. More is not better. Overdosing wastes money, raises the risk of crop damage, and pushes residue above safe limits. Underdosing lets survivors breed resistance. The rate on the label is the rate that was tested.

Finally, look for the pre-harvest interval — the number of days that must pass between the last spray and harvest — and the PPE requirements. The pre-harvest interval protects whoever eats your produce. The PPE protects you.

If anything on the label is unclear, bring it to us. Walking a customer through a label is part of what we do at the shop, and it costs nothing.
