Practical findings from Horticultural Development Council trial, plus summaries of academic research and scientific trials, compiled by Dr Ken Cockshull.

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

Science into practice - Fertilisers for peat reduction

The drive to move horticulture away from peat-based growing media has presented a challenge for growers as they strive to produce quality plants in peat-reduced and peat-free materials.

Science Into Practice - Biocontrols for tackling insects

CP 082 Discovery and development of new phylloplane biocontrol agents to control insect pests (AHDB Horticulture studentship)
