Is this a Minor Pest?
Yes
Minor Pest Title
Late blight (Phytophthora infestans)
Minor Pest Description
The late blight fungus affects tomatos, potatoes and eggplants but not pepper. Its symptoms consist of brown spots with purplish tinge and they can develop on leaves, stems, branches and both green and ripe fruits. In moist weather it can cause complete defoliation and rotting of fruits.
Minor Pest What to do.
- Use resistant varieties, if available
- Practise rotation with non-solanaceous crops (e.g. tomato, potato, peppers etc) for 3 to 4 years. However, this will only be effective if it is done in cooperation with neighbouring farmers since the fungal spores can travel quite large distances by wind.
- In wet weather, copper fungicides, could be applied as soon as the disease is observed or as soon as local experience suggests that the weather conditions are favourable for disease development.
