What to do about thrip damage on your plants

Symptoms

Our “gogga” of the month for June, thrips, are likely to cause distorted, papery leaves, with pale brown spots on them

What does this mean for me/my plants?

Plant growth is stunted and leaves drop prematurely if not treated. Thrips damage the plants by sucking the sap and can also transfer viruses.

Suggested Action

To identify if it is thrips – blow on the plant and you will see them move around. Otherwise they are not seen easily. Treat with a concentrated insecticide. Examples of plants they attack:

– Houseplants: African violet, azalea, begonia, brugmansia, croton, crassula, cyclamen, dieffenbachia, ficus, fuchsia, gerbera, gloxinia, hibiscus, impatiens, orchid, pelargonium, streptocarpus, yucca.
– Edible plants: apple, asparagus, basil, bean, blueberry, carrot, cherry, cabbage, corn, cucumber, garlic, grape vine, leek, onion, pea, pear, pepper, potato, raspberry, strawberry, tomato.
– Annuals, perennials and bulbs: aster, carnation, chrysanthemum, dahlia, gladiolus, iris, lily, peony, petunia, pelargonium, snapdragon, sweet pea, verbena, zinnia.
– Woody plants: birch, hydrangea, linden, maple, privet, rose, willow.
