How to Look Up a BKÜ in Turkey: A BKU Lookup Walkthrough for Agronomists

What is BKÜ GPT?

BKÜ GPT is a free lookup tool for plant protection products in Turkey. Bitki Koruma Ürünleri, abbreviated BKÜ (or BKU without the Turkish Ü), covers the products an advisor recommends every week: insecticides, fungicides, herbicides, acaricides, plant growth regulators, and biological controls. The lookup currently covers 5,597 approved BKÜ at last count and grows as new products are registered.

Open the lookup at bkugpt.com.

How to look up a BKÜ in Turkey

Type what you know into the search field. The lookup accepts a crop, a pest, an active ingredient, a trade name, a registration number, or any combination. A search for aphid on cucumber returns every BKÜ approved against aphids on cucumber in Turkey, with the dose and pre-harvest interval visible without opening each product page.

Three things to know before the first lookup:

1. The lookup works in Turkish and English. Kırmızı örümcek çilek and red spider mite strawberry return the same BKÜ.
2. BKU and BKÜ both work as the acronym. The Turkish Ü is correct, the unaccented BKU is understood.
3. Filters narrow the result. A bare query like aphid returns hundreds of products. With filters set to crop and formulation, the result is short enough to read on one screen.

How to look up a BKU by crop and pest

Field calls usually start with a crop and a problem. A grower describes whitefly on tomato, mites on strawberry, mildew on grape. Type both terms together. The result is the list of BKÜ approved for that crop and that target.

Each row in the result shows the trade name, active ingredient, formulation type (EC, WG, SC, SL, WP), the dose per decare or per 100 L of water, and the pre-harvest interval in days. A multi-crop client does not need a second lookup. The dose for tomato and the dose for cucumber are on the same product page, in their own rows.

How to look up a BKÜ by active ingredient

A grower mentions an active ingredient that worked the previous season. Type the ingredient name on its own. The result lists every BKÜ registered in Turkey that contains that ingredient, grouped by manufacturer and concentration. This is the lookup to run when a specific trade name is out of stock and you need a substitute with the same active ingredient and a comparable concentration.

A search for imidacloprid returns every approved BKÜ in Turkey with imidacloprid as the active ingredient. A search for abamectin 18 g/L narrows it to the concentration the client asked for.

How to look up a BKÜ by trade name or registration number

A grower brings a name from a neighbor or a local agro-store. Type the trade name. The product page lists every crop the BKÜ is approved on, the dose per crop, the target pest or disease per crop, and the registration number.

If the grower brings a registration number, type the number. A registration number pins one BKÜ across label revisions, so it is the cleanest way to confirm you are looking at the correct product.

How to filter a BKÜ lookup

The filter chips on BKUGPT are:

• Crop
• Pest, disease, or weed
• Active ingredient
• Formulation type
• Manufacturer

Pick one. Combine three. The result list updates without a page reload. When a filter combination matches a recurring client situation (apple grower, codling moth, organic certification), bookmark the URL. The same BKÜ lookup is one click away next season.

How to verify a BKÜ before recommending

A BKÜ lookup is the start of a recommendation, not the end. Three checks belong in every advisor workflow:

1. Confirm the registration status on the product page is current. A withdrawn BKÜ should not appear in a written recommendation.
2. Confirm the dose against the printed label on the package the grower will buy. Labels change between revisions. The number on a five-year-old bottle may differ from the number registered today.
3. Confirm the pre-harvest interval against the grower's planned harvest date. A 14-day interval and a harvest in 7 days rules a product out, regardless of how well it controls the pest.

For more on the term itself and what counts as a BKÜ, see What is BKÜ?.

Example: a strawberry recommendation in 90 seconds

A strawberry client calls about red spider mite. Harvest is in 5 days. You open the BKÜ lookup and type red spider mite strawberry. The result is the list of acaricides approved for strawberry in Turkey.

One product has a 3-day pre-harvest interval. Another has 7. With harvest in 5 days, the 3-day product is the only BKÜ you can recommend. You copy the trade name, the active ingredient, the dose per decare, and the manufacturer into the report. Total time on the lookup: under 2 minutes.

How much time does a BKÜ lookup save?

For an advisor writing 12 written recommendations a week, the lookup turns 30 minutes per recommendation in catalogs and PDFs into about 5 minutes. That is roughly 5 hours back each week, redirected to field visits, follow-up calls, or season-long planning with bigger clients.

When to run a BKÜ lookup

Run the lookup before signing a written recommendation. Run it before quoting a dose to a client over the phone. Run it before approving a season-long protection program. Any time the question is which BKÜ is approved in Turkey for this crop and this problem, and at what dose, the lookup is the place to start.
