This factsheet is intended to increase grower awareness of Nesidiocoris (Cyrtopeltis) tenuis, and the damage that it causes, as well as helping growers to distinguish it from Macrolophus pygmaeus – a similar mirid bug which is already used in tomato IPM programmes in the UK.
7 September 2020
Pepper internal fruit rot caused primarily by Fusarium lactis has been a continuing problem in UK pepper crops since around 2000. This Factsheet describes the common pepper fruit rots. Information is provided on the biology of each disease and the measures that can be taken to reduce disease risk.
7 September 2020
In this factsheet, the symptoms, biology and the epidemiology of this fungal pathogen (Mycosphaerella melonis) are described. Guidelines on how to manage the disease by good hygiene, cultural measures and options for chemical and biological control are outlined.
7 September 2020
This guide describes the biopesticides registered as plant protection products and outlines how they can be used successfully as part of IPM programmes in horticultural crops. It discusses the types of biopesticide available and how they work, and their advantages and limitations. A list of biopesticides currently available in the UK is provided.

Tuta absoluta was first intercepted in the UK on Spanish imports in March 2009 and there soon followed an outbreak in a commercial tomato crop. By 2011 it was considered to be the greatest threat to UK tomato production. This factsheet describes a new control strategy which is compatible with the existing tomato IPM programme.

Leaf mould is one of the most destructive foliar diseases of tomato when the crop is grown under humid conditions. This factsheet provides information on disease symptoms and disease epidemiology, and provides guidance on how to manage the disease using cultural measures, resistant varieties and plant protection products.

The southern green shieldbug has been recorded annually from sites in southern Britain since 2003. It is becoming increasingly common in glasshouses in the London area where it has caused significant damage to sweet pepper and aubergine crops. This factsheet provides an introduction to the biology and recognition of the pest.
