Science Into Practice - How to control fruit rot in sweet pepper crops

Fusarium internal fruit rot of sweet peppers grown in glasshouses is an increasing problem. A UK survey in 2007 showed infected fruits present in many crops at levels from one to 37 per cent (PC 260).

The disease causes some losses on production nurseries as well as triggering rejections by packers and complaints from supermarkets. Several pathogenic species are associated with the disease, notably F. lactis and F. oxysporum.

Observations in commercial crops indicate the disease is favoured by high humidity and fluctuating temperatures. As yet there is no practical method of control. This three-year project (PE 007) aims to reduce losses through increased knowledge of factors associated with a high incidence of the disease and use of biofungicides and fungicides to control flower infection.

Benefits to the industry include the knowledge of how some crop and environment factors influence disease risk and the identification of targeted treatments of biofungicides and fungicides in at-risk glasshouses on the most susceptible varieties or during weather periods favourable to the disease.
