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

Science Into Practice - Mushroom disease control

Sporgon (prochloraz-manganese), the only approved fungicide available to the UK mushroom industry, provides good control of wet bubble (Mycogone perniciosa), moderate control of dry bubble (Lecanicillium fungicola) and weak control of cobweb (Cladobotryum species).

Science into practice - Cut flowers trialled on water

The only reliable current control method for the soil-borne disease Fusarium oxysporum in cut-flower production is steam sterilisation, but this is expensive, time-consuming and large losses can still occur even where the soil has been treated.

Science Into Practice - Blueberry gall midge control

SF 126: Blueberry gall midge - sex pheromone monitoring and control with insecticides

Science into Practice - Investigating heuchera rust

Heuchera rust was first identified in the UK in 2004 but incidence has increased significantly since 2010 across a range of different heuchera varieties.

Science Into Practice - Understanding daffodil rust

BOF 076a: Understanding physiological disorders in narcissus - extension to studying the three-year down crop

Science into practice - Eliciting plants' natural defence

CP 105: Integrated protection of horticultural crops through enhancing endogenous defence mechanisms (AHDB Horticulture Studentship)

Science into practice - 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.
