Earwig-safe crop protection

Earwigs are important generalist predators in apple and pear orchards. They play a key part in regulating populations of several highly damaging pests including woolly and other aphid pests, mussel scale, codling moth and pear sucker. Recent research in the UK and Europe has indicated that several commonly used crop-protection products have harmful effects on earwigs in orchards.

Science Into Practice - Controlling downy mildew

Impatiens downy mildew (IDM), caused by Plamopara obducens, is a foliar disease specific to impatiens. A metalaxyl-M-resistant strain of P. obducens was introduced into commercial production in early 2011, resulting in widespread, difficult-to-control downy mildew infections.

Science into practice - Post-harvest lettuce pinking

FV 413a: Lettuce: Predicting high-risk plantings to manage post-harvest pinking

Science into practice - Blackcurrant crop protection

Botrytis, leaf-curling midge and sawfly are economically damaging diseases and pests of blackcurrants. Botrytis not only causes grey mould of the fruit but can give rise to "run-off" in spring, leading to reduced yields. Leaf-curling midge stunts growth in shoot tips, slowing bush growth, while blackcurrant sawfly can lead to defoliation of the bush.

Science Into Practice - Downy mildew on impatiens

PO 011b: Monitoring metalxyl-M sensitivity of Downy Mildew infection of Impatiens

Science Into Practice - Ethylene and irrigation

CP 081 Detection and amelioration of root-zone ethylene production in protected crops

Science into practice - Identifying mildew sources

Project HNS 196 Identification of inoculum sources for the newly emerged Peronospora causing downy mildew on aquilegia.

Automated harvesting

Harvesting is one of the most labour-intensive and costly operations in horticulture. AHDB Horticulture is supporting a project led by KMS Projects to automate these processes to create a system that can be developed to automate the harvesting of other crops such as cauliflower and lettuce, with the ultimate objective to deliver commercial benefits.

Science Into Practice - Bacterial canker on plum trees

Bacterial canker is a destructive disease of plums and cherries that has been causing ongoing problems for growers for many years.

Science Into Practice - Better control of Scaptomyza

In the UK in 2009, Scaptomyza flava was identified as the pest responsible for the economic damage on watercress and Cruciferae grown as baby-leaf salads.

Science into Practice - Better methods for bulb planting

CP 103: The application of precision agronomy to UK production of narcissus (AHDB Horticulture studentship 2013-16).

Science Into Practice - Tomato leaf mould defences

PE 018 Efficacy of conventional fungicides, biofungicides and disinfectants against tomato leaf mould (Passalora fulva)

Science Into Practice - Dry matter's link to quality of fruit

Project TF 222: Desk study looking at the relationship between dry matter content of apples and fruit quality.

Science Into Practice - Winter brassica crop research

FV 202g - Brassicas: an evaluation of autumn/winter cauliflower cultivars, spring cabbage cultivars and other winter brassica crops
