This factsheet guides the implementation of practical food safety and risk assessment. It provides background information on important potential microbial contaminants of fresh produce, and also considers the role of microbiological testing of indicator species for water and fresh produce.

7 September 2020

A summary of recent studies on the causal bacterium, symptom development and disease spread.

7 September 2020

IPM compatible options for control of southern green shieldbug, Nezara viridula, a new pest of pepper and aubergines, and potential control measures.

7 September 2020

This guide covers fungal and Oomycete disease of lettuce.

7 September 2020

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.

7 September 2020

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.

7 September 2020

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.

7 September 2020

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.

7 September 2020

This factsheet provides an introduction to the biology, behaviour and recognition of the main groups of hyperparasitoids which commonly attack the primary parasitoids used for biological control of aphids in UK crops.
