Blueberry Pests Diseases & Disorders

In the U.K. blueberry plants are largely trouble free and can be grown organically very successfully. In the USA various grubs attack the fruits but in the U.K. the most troublesome pests are birds.

The most serious diseases are Blueberry Stem Blight and Blueberry Root Rot.

USING CHEMICALS SAFELY – ALWAYS READ THE LABEL

When using chemicals it is most important to follow the manufacturer’s instructions precisely.  Only use on the fruits that are listed on the manufacturer’s label.  An accurate weighing machine and measuring cylinder should be obtained.  Chemicals can be wasted by making concentrations unnecessarily strong or by making them too weak and ineffective.  Furthermore, if chemicals are too strong they may cause damage to the foliage.

Only spray in the early morning or evening when the weather is dry and calm.  Avoid spraying when fruit canes and bushes are in flower, to reduce the risk of killing helpful pollinating insects such as bees.
