Natural treatment with SF nematodes to effectively eliminate thrips and their larvae, safe for humans, animals, and beneficial insects, ideal for vegetable gardens, greenhouses, and plants.
Read moreTreating thrips (Frankliniella occidentalis), or western flower thrips, can be challenging due to their small size, rapid reproductive capacity, and sometimes their resistance to pesticides. Here are some treatment strategies and information on the damage caused by these thrips:
Biological control: Using natural enemies such as thrips nematodes, such as predators or parasites specific to thrips, can be an effective method. Certain predatory insects and parasitoids can help reduce the thrips population naturally.
Insecticides: Insecticides are often used for thrips control. However, some populations of Frankliniella occidentalis have developed resistance to certain pesticides, making it important to choose suitable products and follow usage recommendations.
Cultural control: Certain cultural practices can help reduce thrips populations. This may include weed management, crop rotation, and the use of insect-proof nets.
Leaf necrosis: Thrips feed by piercing plant cells and sucking out the cell sap. This can lead to leaf necrosis and silvery or bronze spots on leaves.
Shoot deformation: Thrips feeding can also cause deformation of young shoots and flower buds.
Virus transmission: A critical aspect of the damage caused by Frankliniella occidentalis is its ability to transmit certain plant viruses. These viruses can cause serious diseases in plants, affecting their growth, yield, and sometimes their survival.
General weakening: When thrips populations are high, plants can suffer general weakening due to the loss of nutrients and energy caused by the insects’ feeding.
The soil must be pre-moistened to facilitate the dispersion of the nematodes. Outdoors: apply in the morning, in the evening, or in overcast weather because they are very sensitive to U.V.
To apply SF nematodes: with a watering can or a sprayer
| Packet of | Treated area | To dilute in |
Effectiveness |
| 5 million | 15 m² | 5L of water | 6 weeks |
| 10 million | 30 m² | 10L of water | |
| 25 million | 75 m² | 25L of water | |
| 50 million | 150 m² | 50L of water | |
| 100 million | 300 m² | 100L of water |
It is recommended to use the nematodes as soon as they are received; they will be delivered at room temperature, therefore no longer dormant. You must keep them at room temperature because they are active between 12 and 28°C. (Cold is only used to store them inactive for several weeks).
* For thrips, treatment is possible year-round for protected crops (greenhouse, conservatory, tunnel, etc.) or outdoors, but the soil temperature must be between 12°C and 28°C.
