Exemption authorisation for MINECTO GOLD against larvae of the European flea beetle in oilseed rape

18 Sep 2023

MINECTO GOLD (s.a. cyantraniliprole) has just been granted a marketing authorisation under the 120-day derogation (art53 - REG 1107/2009) from 25 September to 31 December 2024.

As part of the phosmet phase-out action plan, Terres Inovia and Terres Univia have joined forces for the third year running to provide growers with an operational solution for controlling autumn rapeseed pests in a context of reduced availability of treatment solutions and strong resistance to pyrethroids (Skdr mutation), in addition to all the tools of integrated protection. This is the ‘robust rapeseed®’ concept.

This derogation is limited to the regions of Grand-Est, Bourgogne-Franche-Comté, Ile-de-France, Centre-Val-de-Loire and the departments of Allier, Puy de Dôme, Aisne and Oise. These are the regions concerned by the proven phenomena of high resistance of flea beetles to pyrethroids.

MINECTO GOLD (cyantraniliprole 400 g/kg, MA 2220766) has been approved for use on oilseed crucifers *treatment of aerial parts* phytophagous beetles on oilseed rape and mustard only.

On oilseed rape, MINECTO GOLD is authorised as a single application (maximum 1 application per year) at a maximum use rate of 100 g/ha from BBCH16 (6 leaf stage of oilseed rape) to BBCH19 (9 leaf stage or more).

On mustard, the conditions of use (number and stage of application) are different.

Main regulations:

Application methods: berlèse test beforehand and reasoned intervention based on risk assessment using available decision support tools.

SPe 1: To protect groundwater, do not use this product or any other product containing cyantraniliprole more than one year out of 3 on the same plot.

SPe 3: To protect aquatic organisms, a 20-metre untreated zone must be maintained in relation to water points, with a 20-metre wide permanent untreated vegetation strip bordering water points.

SPe 3: To protect non-target arthropods, maintain a 5-metre untreated zone in relation to adjacent uncultivated areas.

SPe 8: Dangerous for bees. To protect bees and other pollinating insects:

Do not use in the presence of bees
Do not apply during flowering or exudate production periods
Do not apply to foraging areas

Protection of residents and bystanders: Maintain a distance of at least 5 metres between the spray boom and areas likely to be frequented by residents, as well as areas frequented by people at the time of treatment.

Flea beetle larvae are the target of MINECTO GOLD in rapeseed crops.
The start of the exemption date is adapted to the mustard sector. In oilseed rape, flea beetle larvae are the target, with a single application that cannot be made before the 6-leaf stage of the crop and a Berlèse test carried out beforehand.

Terres Inovia's recommendations

Insecticide application is a complementary control lever to the agronomic measures used to establish a robust rapeseed that is less susceptible to pests.
The MINECTO GOLD solution should be reserved for control of flea beetle larvae in regions where strong resistance to pyrethroids is widespread or increasing (Skdr mutation).
Application is made if necessary, after assessing the risk in the field, which depends on the rapeseed's growth dynamics and the number of larvae (Berlèse test). THE OAD "Rapeseed - risk of flea beetle larvae". You can access this information free of charge on the Terres Inovia website.

Where necessary, protection should be applied at the start of winter, between November and early December.
