Thrip Nematodes 60sqm

Thrip Nematodes 60sqm are microscopic worms that seek out thrip larvae and pupae in the soil and on leaf surfaces, then feed and multiply inside them to prevent these sap-sucking pests from damaging your precious plants. Thrips, also known as thunder flies, can cause significant harm to leaves and flowers in gardens, greenhouses, and houseplants. Nematodes are naturally found in soil—by using this product you are simply topping up the natural population.

These nematodes provide a natural solution to control and reduce thrip populations. They target thrips species that suck sap from leaves and flowers, causing noticeable plant damage.

What are Thrips?

Thrips are insects of the Thysanoptera order, with about 150 species found in Britain. While many thrips do not harm host plants, some species can cause significant damage. Understanding their appearance and symptoms can help in effective management.

Symptoms: Leaves fed upon by thrips often become dull green and later develop a silvery-white discolouration on the upper surface. The discoloured areas are usually marked by many tiny black excrement spots. Thrip feeding on developing tissues at shoot tips or in flower buds can cause distorted growth. Flower petals may show white flecking, resulting from pigment loss due to thrips feeding.

In greenhouses, thrips can breed all year round. Many species also survive year-round outside, ready to attack when warm weather arrives.

Adult thrips are narrow-bodied, up to 2mm in length, with two pairs of strap-like wings fringed with hairs that fold back over their bodies at rest. The immature nymph stages are wingless, generally creamy yellow, and paler than adults.

Nematode products are renowned biological controls, providing many benefits over traditional gardening chemicals and are a key ally for organic gardeners.
