Chemical control products

Strawberry growers and their agronomists continually strive to reduce the use of chemical control products, not only to reduce the risk of incurring chemical residues, but also to avoid the adverse effects that some products have on natural and biological control programmes already being implemented in the crop. To this end, they do all they can to employ cultural, natural or biological control methods before using chemical control products. 

However, there are times in the season when a combination of pest pressure, weather conditions and use of products for other pests and diseases conspire to enforce the use of a chemical product for aphid control. When choosing such a product, it is essential to consider the impact it may have on existing biological or natural control programmes that are already in place and whether its use will be compatible with IPDM programmes. The table below lists those products that are currently approved for use on strawberry (October 2020) and provide control of aphids or will give some incidental control when applied for other pests of strawberry.

Growers should always consult a BASIS-qualified agronomist before choosing the most appropriate product.

This table has been collated using information from the Health and Safety Executive (HSE) website (pesticides.gov.uk) and from product labels and supplier technical leaflets. Important – regular changes occur in the approval status of plant protection products, arising from changes
in the legislation or for other reasons. For the most up-to-date information, please check the HSE website or with a professional supplier or BASIS-qualified consultant, as information could have changed since the publication of this web page.

Growers must hold a paper or electronic copy of an EAMU before using any product under the EAMU arrangements. Any use of a plant protection product via an EAMU is at the grower’s own risk.

Always follow approved label or EAMU recommendations, including rate of use, maximum number of applications per crop or year, and where crop safety information is not available, test the product on a small number of plants to determine crop safety prior to widespread commercial use.
If in doubt about which products are permissible on your crops or how to use them correctly, seek advice from a BASIS-qualified consultant.
