Nitenpyram 25% SP: How to Check Label Rates and Supplier Documents

Buyers often search for a “nitenpyram 25 SP dose per litre” before comparing suppliers. A product title cannot answer that question. The percentage identifies a declared concentration and SP identifies a formulation type; neither specifies an approved crop, pest, spray method or water volume. This guide explains the checks that turn a catalogue listing into a usable procurement question. It is not an application instruction.

Why a single dose per litre is misleading

The FAO explains that an approved pesticide label contains authorized uses, directions and precautions. Its label-data guidance calls for rates, application methods, water volumes, timing and restrictions to be stated for the specific product. A per-litre number copied from another brand, country or crop can therefore be wrong even when both product titles say 25% SP.

Start with the exact product identity and destination market. Read the current registered label for the crop and target pest. Check whether the rate is expressed per area, per volume, per plant or by another basis, and read the stated water volume and application method together. Then confirm limits on applications, timing, re-entry, harvest interval and local protective measures. If any required item is absent, seek the registrant or local agronomist’s answer instead of calculating a rate from 25%.

A “dose per litre” can also hide a change in total amount applied per hectare: two operators can use the same tank concentration but very different spray volumes. Conversely, an area-based label rate does not translate into one tank concentration without the approved water-volume range and calibrated equipment. Keep the label’s original units when comparing supplier offers and application plans.

What 25% SP does—and does not—describe

SP is the standard code for a water-soluble powder in FAO/WHO formulation terminology. The code is useful for identifying the physical product being purchased and the appropriate specification tests. It does not prove how quickly a particular batch dissolves, whether it is compatible with another tank product, or whether it has a local registration. Request the exact specification and supporting test methods rather than relying on the letters alone.

Averstar lists a straight Nitenpyram 25% SP Insecticide. Its catalogue page is a starting point for an inquiry, not an approved use label. Ask whether the declared 25% is stated on the same basis as the proposed specification and label, and have the supplier identify the manufacturer, formulation version and intended country of registration. A sample or COA should be traceable to the version being quoted.

Do not compare the mixture titles as interchangeable strengths

The catalogue also lists Nitenpyram + Pymetrozine 20% / 60% WG and Dinotefuran + Nitenpyram 40% / 20% WP. These are different active-ingredient combinations and different physical formulations. The two percentages in each title are active-by-active declarations, while WG and WP identify different formulation types from SP. They are not simply “stronger 25% SP” products, and no field rate or crop claim transfers between them.

IRAC lists both nitenpyram and dinotefuran among Group 4A neonicotinoids. Putting two Group 4A actives in one product is not a rotation to a different mode of action. A buyer considering a resistance program should check the target pest, local susceptibility, approved use pattern and advice from the local extension or registration authority. A mixture title alone does not establish resistance-management value.

A practical label and document review for importers

1. Match the product: record every active ingredient, concentration and unit; identify SP, WG or WP; and confirm the offered manufacturer and exact formulation version. Ask the supplier to state whether the quote is for a registered finished product or a proposal requiring local registration work.

2. Check market authorization: request the proposed label, registration number or application status, registrant name and destination-country evidence. Verify the current status with the competent authority or local registrant. An English catalogue page and a draft label are not evidence that sale or use is approved.

3. Read the whole use pattern: the approved crop, pest, rate basis, dilution or water volume, method, timing, application limits and restrictions belong together. Do not import a field rate from another country’s label. Ask a local qualified adviser to resolve any uncertainty before use.

4. Compare quality records: ask for a current specification, a representative certificate of analysis, relevant test methods and storage-stability information for the exact formulation. FAO notes that pesticide specifications help define product quality, but a specification from another source or product version cannot establish the offered batch’s identity.

5. Confirm safety and shipment details: obtain the current safety data sheet, proposed packaging and label artwork, net content, shelf life, transport information and batch traceability. Align documents with the destination requirements before approving artwork or committing to a commercial shipment.

Send a clearer request for quotation

An effective RFQ names the destination country and asks for the exact product configuration, each active concentration with its units, formulation code, proposed local label, registration status, specification, representative COA, SDS, pack sizes, MOQ and lead time. If an application question prompted your search, describe the crop and pest but ask for the approved label section rather than requesting a generic tank-mix number. This gives the supplier a defined question and gives the buyer documents that can actually be checked.

For a broader comparison of modes of action and sourcing records, see the insecticide classification guide. Use the product pages above to identify the proposed configuration, then evaluate only the destination-market approval and supporting batch evidence for that exact version.
