A single unchecked jassid flare-up in cotton can cost more per acre than a full season of planned sprays. Verta protects the schedule at roughly the cost of a day's labour per acre.

One borer-damaged picking in chilli drops the lot a full grade. At 60 ml per acre, Coreon costs a fraction of the grade it protects.

Thrips scarring at bloom marks the berry for the rest of the season. One planned spray at 75 ml per acre protects the export grade that no later spray can restore.

A downy mildew miss in grapes can take out a season's bunches in a week of rain. Azoxin holds the window at a cost that disappears against the value of one saved harvest.

Late blight moves faster than any curative programme. Curalis is priced against the cost of standing in a lost tomato block — not against the cheapest bag on the shelf.

Fruit rot at the finish undoes a season of good work. At 250 ml per acre, Tebura protects the final grade for less than one percent of the crop's standing value.

The first 45 days of weed competition in cotton cost more yield than most pests. One timed application per acre protects the stand at the stage that decides the boll load.

Compare one planned pre-emergence application against two rounds of hand weeding per acre — the arithmetic settles itself before the crop is a month old.
