Columnea latent viroid (CLVd) is one of nine viroids known to affect tomatoes.

Research Matters - Fruit thinning in apple trees: update

03 Feb 2012 | by Dr Ken Cockshull

Fruit thinning is often required to produce a commercially profitable apple crop, yet fewer chemicals are now approved for this purpose.

Science Into Practice - New controls for cabbage root fly in brassicas

03 Feb 2012 | by HDC

Cabbage root fly larvae feed on plant roots, causing the most serious damage to young transplants soon after planting in the field.

Science Into Practice - The influence of storage on Bramley rotting

27 Jan 2012

Many growers commonly lose 10 per cent or more of late stored Bramley apples, particularly through Nectria galligena, the fungus that causes apple canker in the orchard. The five per cent CO2, one per cent O2 storage regime improves control of bitter pit and superficial scald, but this has the adverse...

Research Matters - Strawberry flowering update

20 Jan 2012 | by Dr Ken Cockshull

The cost of strawberry transplants can be lowered by removing the tips of runners that hang down from tabletop production systems and rooting them in cellular trays.

Science Into Practice - Improving the efficiency of fungicides

20 Jan 2012 | by HDC

Fungicides are vital for controlling leaf spots on brassicas. If fungicides are timed right, efficacy can be enhanced and the need for re-application reduced. However, optimal timing relies on accurate monitoring or prediction systems that identify when the damaging or vulnerable pathogen life cycle...

Research Matters - Fruit thinning in apple trees

Apple growers sometimes have to use fruit-thinning agents to stop their trees producing too many small fruit.

Science Into Practice - Non-pesticidal controls for key fruit problems

13 Jan 2012 | by HDC

Aphids, plum fruit moth, light-brown apple moth and brown rot are very common pest and disease problems of stone fruit wherever and however the crops are grown in the UK. Together they cause significant yield losses every year.

Research Matters - Flower initiation in strawberry

16 Dec 2011 | by Dr Ken Cockshull

Nitrogen fertilisers apparently delay flowering of June-flowering strawberries if applied before flower initiation begins, yet they can promote flowering if applied after flower initiation has started.
