CB2104 - CROP UPDATE 4 - 28th May 2021

PGRO Crop Update   Number 4.   27th May 2021
Approval has been received for the use of InSyst on the 2021 field bean crop for seed production only, to control bruchid beetles (Bruchus rufimanus). 27th May - 31st August 2021.
Please note that there are several key points of stewardship that must be observed:
Guidance for use of insecticides in field beans to control attack by bruchid beetles (B. rufimanus) is as follows:

  1. There is no threshold for beetle numbers in the crop, however presence of the pest in field bean crops must be established prior to insecticide application. This can be done by examining flowers, either by opening the flowers to expose the beetles, or by tapping out the flower heads onto a plastic tray. Images of bruchid beetles can be found on our website at to aid identification. There is no effective trap system available to monitor bruchid presence in flowering field bean crops;
  2. Previous experience of high levels of bruchid damage to field bean grains should be used to indicate whether presence is likely to occur in crops. Where damage to field beans is greater than 20%, use as seed may be compromised.
  3. There is a temperature and crop growth stage threshold that triggers oviposition by bruchids, and subsequent insecticide use to control the pest in field beans as follows:Applications should take place only when maximum daily temperature has reached or exceeded 20°C for two consecutive days, and only when the crop has reached the first pod formation stage (when 50% of pods on the bottom truss have reached 2cm length). Oviposition begins when temperature reaches this threshold, and bruchids lay eggs only on pods.
  4. Insecticides should be used when beneficial insects, particularly bees, are not foraging in the crop. As such, applications should take place late in the evening, very early in the morning or at night time;
  5. A single application only is permitted, when the requirement of points 1 to 4 have been met;
  6. All user and environmental safety precautions listed on the Insyst label, for public, livestock and wildlife, must be followed;
  7. Growers are encouraged to follow PGRO bulletin and website updates for bruchid activity and recommendations. Advice for the use of insecticides will be distributed via PGRO, as crop updates to our mailing list, via the website and through our regular industry panel meetings to ensure stewardship guidance is followed;
  8. When applying this product under the terms of this Emergency authorisation, comply with any resistance guidance or restrictions stated on the product label.
  9. Monitoring of the impact on levels of damage in crops will be carried out in 2021 by continued analysis of the UK data provided to PGRO;
  10. Continued monitoring of the impact on levels of damage to seed germination capacity will take place via analysis of seed samples submitted to the PGRO seed testing laboratory in 2021;
  11. Horizontal boom sprayers must be fitted with three star drift reduction technology for all uses.
  12. Growers must adhere to 6m aquatic buffer zone.

HSE Digital Signature
This and the attached Appendices 1 and 2 are signed by the Health and Safety
Executive for and on behalf of the Secretary of State and the Welsh Ministers.
Date of issue: 27 May 2021
1. This is Emergency authorisation number 1158 of 2021.
2. This Emergency authorisation will be published on HSE’s website.
3. Application reference number: COP 2020/01900
4. Persons using the product to which this Emergency Authorisation applies should acquaint themselves with and observe all requirements contained in the
Regulation (EC) No 1107/2009, including the duty on the holder of any
Emergency authorisation to notify information on potentially dangerous effects,
a contravention of which is a criminal offence under those Regulations.
5. Neither the efficacy nor the phytotoxicity of the product for which this
Emergency authorisation has been granted has been assessed and, as such,
the user bears the risk in respect of failures concerning its efficacy and phytotoxicity.
6. In this notice Regulation (EC) No 1107/2009 means:
In relation to Great Britain, Regulation (EC) No 1107/2009 as it has effect in
Great Britain.
This Emergency authorisation relates to the use of ‘InSyst’ (MAPP 13414) for the
control of Bruchid beetle (Bruchus rufimanus) in field bean grown for seed production only.
Applications to be made via horizontal boom sprayer in water volumes of 200 to 500 litres water per hectare. The latest time of application is before 50% of pods have reached typical length (BBCH 75).
‘InSyst’ should be applied at the recommended rate of use and in sufficient water volume to achieve the required spray penetration into the crop and uniform coverage necessary for optimal pest control.
IMPORTANT: When applying this product under the terms of this Emergency
authorisation, comply with any resistance guidance or restrictions stated on the
product label.
Total reliance on one pesticide will hasten the development of resistance; pesticides of different chemical types or alternative control measures should be included in a planned programme. Alternating insecticides with different modes of action is a recognised anti-resistance strategy and ‘InSyst’ should be used in alternation with insecticides of a different mode of action, giving consideration to the overall treatment programme on the crop against a range of pests.
For any returning application the following data requirements must be addressed:
Demonstration that the conditions of authorisation were complied with. It is suggested that this in the form of a report collating the records required as set out in other specific restriction 2 (i.e. area treated, presence of pest, daily temperatures, crop growth stage).
This Emergency Authorisation will expire on 31 August 2021.
The conditions below are obligatory. They must be complied with when the
Emergency authorisation occurs. Failure to comply with the following conditions will result in the withdrawal or amendment of the Emergency authorisation under
Regulation (EC) No 1107/2009 and may result in other enforcement action, including prosecution.
