Welcome to Rob Jacobson Consultancy

RJC is a specialist consultancy providing award winning services to the horticultural industry.

We focus on integrated pest management (IPM) and are one of very few organisations who specialise in the implementation of whole IPM programmes. This is achieved via direct consultancy, training and contract R&D.

We approach each new project by assembling a unique team of appropriately qualified associates. Past projects have involved various combinations of growers, consultants, supply companies, researchers and academics.

Recent Activities

Nesidiocoris tenuis: Grower awareness factsheet

Both adults and nymphs of this non-indigenous mirid bug are predators and they can make a useful contribution to IPM. However, in the absence of insect or mite prey, they turn their attention to tomato plants causing serious damage. This factsheet increases grower awareness of the potential problem as well as helping to distinguish it from the related indigenous predator, Macrolophus pygmaeus. (Go to Information Sheets).

Pollination issues in UK tomato crops

British tomato growers have been using commercially reared bumblebees to pollinate their crops since 1989. The benefits had become vital to cost effective production. In 2014, Natural England withdrew permission to use non-native sub-species of Bombus terrestris in unscreened glasshouses. The switch to a native sub-species proved to be far from the reliable experience to which growers had become accustomed. The Tomato Growers’ Association asked Dr Jacobson to organise an in-depth survey to gather more information about the current situation. (Go to Testimonials).

Tuta absoluta: Mating disruption trials spectacularly successful

Working on behalf of the British Tomato Growers’ Association in 2017, Dr Jacobson organised trials with the novel mating disruption product, Isonet-T. The studies, which were funded by AHDB and hosted by Jan Bezemer & Sons, were hugely successful. The technique was immediately adopted by many other UK tomato growers with equally spectacular results. (Go to Testimonials)

Dr Jacobson joins AHDB Biopesticides & ‘Key Gaps’ projects

Dr Jacobson is a consultant to two important AHDB cross sector projects. The first, named AMBER, is examining the application and management of biopesticides for efficacy and reliability. The second, named Sceptre Plus, aims to secure label and off-label approvals for new and safer pesticides for use on edible crops. Follow the AHDB website for regular updates on progress.
