Treatment against hazelnut weevils - 25 million HB nematodes

Biological treatment against hazelnut weevils - Heterorhabditis Bacteriophora (HB) nematodes 25 million

The hazelnut weevil is recognizable by its curved rostrum and its ability to perforate the shells of hazelnuts to lay its eggs. The larvae that emerge feed on the inside of the hazelnuts, causing significant crop losses. Early identification of the infestation is crucial to limit the damage. Warning signs include the presence of perforated hazelnuts and premature drop of unripe fruit. In addition to direct damage to crops, the hazelnut weevil can also facilitate the introduction of fungal diseases through the perforations it creates, further compromising the quality of the hazelnuts.
To effectively counter this problem, we offer you an environmentally friendly solution: Heterohabditis Bacteriophora nematodes. These biological organisms target the larvae and nymphs of weevil, interrupting their development cycle without harming the surrounding flora and fauna.
Easy to use and safe for plants, pets and biodiversity, our nematodes offer an ecological and sustainable alternative to chemical pesticides.
Nematodes are microscopic worms that are used as a biocontrol treatment.

ATTENTION :
This is a LIVE PRODUCT with a VERY SHORT use-by date.
Avoid buying them in advance.
Use ALL at the time of TREATMENT because the nematodes are not distributed evenly.

Packaging : Pot of 25 million nematodes for 25 million for 1 hazelnut tree
PS: Pot containing a moist granular powder.

Instructions for use
1. Identify the problem
The hazelnut weevil (Curculio nucum) measures between 5 and 8 mm in length. It is reddish-brown in colour and has a body covered in small scales giving it a velvety appearance. Its most distinctive feature is its long rostrum, used to pierce hazelnut shells to lay its eggs.
The life cycle of the hazelnut weevil begins in the spring, when females lay their eggs inside young, still-developing hazelnuts. The larvae, once hatched, feed on the inside of the hazelnut, burrowing into it. After a few weeks, they emerge and burrow into the soil, where they pupate and overwinter. The adults emerge from the soil the following spring, ready to begin the cycle again.
The damage caused by the hazelnut weevil can be significant. The larvae feed inside the hazelnuts, making them unfit for consumption. In addition, the perforation of the shells by the females for laying eggs weakens the young fruits, which can lead to their premature drop. Severe infestations therefore significantly reduce the yield of hazelnuts, affecting both the quantity and quality of the harvest.
The best treatment period is when the hazelnut weevil larvae move into the soil to overwinter, i.e. in late summer.

2. Preparation of the nematode solution
Before use, leave the nematodes at room temperature for 30 minutes. Dilute the entire sachet in a small container of clean water at room temperature, pre-diluting the nematodes before mixing them. Stir well and let the contents dilute for 5 minutes. Then pour this preparation into your sprayer and add the rest of the water (between 15°C and 25°C). Mix again.

3. Spraying or watering application of nematodes
Before applying the solution to the plants, moisten the foliage to allow the nematodes to move more easily. Spray while continuing to agitate the mixture to prevent the nematodes from ending up at the bottom of the sprayer or watering can.

4. Continue watering
Nematodes require a moist environment to move to their prey. Water your crop regularly to maintain their effectiveness.

5. Monitor the results
Nematodes work quickly to control hazelnut weevil larvae. You should see a decrease in the larvae population after a few days. If larvae persist, repeat the treatment.
It is important to follow the application instructions to achieve the best results.

How are your nematodes delivered to you?
By unrefrigerated tracked letter directly to the mailbox.

Nematodes can survive more than 8 days at room temperature without any problem. Storing them in the fridge is just to be able to keep them longer by slowing down their development.
Nematodes should be kept cool after receipt in order to slow down their metabolism ("hibernation") so that they can be stored until the DLU date.
At room temperature, nematodes do not die but continue their development. Without food (larvae of fungus gnats), they would eventually die naturally after about ten days.

Dosage

Mode of action
Nematodes are naturally present in the soil in small quantities, they are microscopic worms invisible to the naked eye, respectful of useful insects, crops and vertebrates (human beings and domestic animals).

- Nematodes move through the soil looking for pest larvae to parasitize them. When they find them, they enter their bodies through natural channels and multiply inside, causing their death within a few days.
