Pear psylla (Cacopsylla pyri) is one of the most important pests affecting pear crops. Discover how Soptech acts by contact against psylla nymphs and how its cleaning action helps break down honeydew and associated residues.
Pear psylla: a pest that affects both the crop and fruit quality
Pear psylla, Cacopsylla pyri, is one of the main pests affecting pear production. Its populations can develop on leaves, shoots and fruit, causing both direct and indirect damage to the crop.
One of the main problems associated with this pest is the honeydew produced by the nymphs. This sticky substance covers plant surfaces and can favour the development of sooty mould, affecting leaves and fruit and potentially reducing the commercial value of the harvest.
For this reason, managing psylla should not focus exclusively on reducing the insect population. It is also important to address the structures and residues associated with the infestation.
This is where Soptech can become an interesting tool within a crop management strategy.
What is Soptech?
Soptech is a formulation based on long-chain fatty alcohols, developed by Ecoculture Biosciences as an agricultural cleaner with a strong action on organic residues present on plant surfaces.
Its cleaning action helps break down and remove residues such as honeydew and sooty mould, while its contact action can affect the protective outer structures of certain soft-bodied insects.
This combination of cleaning and physical contact action makes Soptech a useful tool in strategies targeting pests such as:
- Pear psylla
- Aphids
- Whiteflies
- Scale insects
- Other soft-bodied insects
How does Soptech act on insects?
Unlike conventional insecticides with a specific biochemical mode of action, Soptech primarily acts through physical and contact mechanisms.
The outer surface of an insect is protected by a cuticle that plays an essential role as a barrier against the external environment.
When Soptech comes into contact with certain soft-bodied insects, its action can disrupt and break down this protective layer, promoting water loss and insect dehydration.
This is why achieving good plant coverage during application is essential.
The product needs to physically reach the insect in order to exert its contact action.
Contact means coverage
This is one of the most important factors to consider when applying Soptech.
It is not simply a matter of applying the product to the crop. The spray must reach the areas where the nymphs are located.
Insufficient coverage can significantly limit the effectiveness of a contact product.
Soptech and pear psylla
In the specific case of Cacopsylla pyri, Soptech is particularly interesting when targeting the nymphal stages of the pest.
Psylla nymphs produce a sticky, sugary substance known as honeydew, which covers plant surfaces and can provide protection for the insects.
When Soptech is applied, its cleaning action begins to break down and disperse the honeydew, changing the structure of the droplets covering the plant surface.
This effect can be clearly observed in field applications.
As shown in the video, a compact, well-defined honeydew droplet is associated with an active psylla nymph, whereas following Soptech application the honeydew becomes dispersed and disrupted.
The loss of this honeydew protection, together with the contact action on the insect’s outer structure, forms part of the mechanism through which Soptech contributes to psylla management.
Why is it important to act on honeydew?
Honeydew is not simply a residue produced by the insect.
Its accumulation on leaves, shoots and fruit can create additional problems.
One of the most important is the development of sooty mould, which can cover plant surfaces and negatively affect the appearance of the fruit.
Honeydew accumulation can also create conditions that contribute to other problems associated with crop quality.
Therefore, an effective psylla management strategy should consider both the insect population and the residues generated by its activity.
This is where Soptech’s dual action — contact + cleaning — becomes particularly interesting.
Soptech: contact action and cleaning effect
One of Soptech’s key characteristics is that its action is not limited to the insect itself.
Its formulation provides a strong cleaning and degreasing effect on organic residues present on plant surfaces. This includes the breakdown and removal of honeydew and sooty mould, as well as disruption of the waxy protective layers of certain insects.
This allows two elements associated with the infestation to be addressed:
INSECT → physical contact action
HONEYDEW → cleaning and disruption
This combination makes Soptech a complementary tool within integrated pest management programmes.
When should Soptech be used against pear psylla?
As with any contact product, application timing is particularly important.
It is preferable to act when the pest is beginning to appear and before the infestation reaches high levels and significant amounts of honeydew have accumulated.
The early nymphal stages are particularly relevant when planning applications.
The objective is to act while good coverage of the pest can still be achieved and before the problem develops into a significant accumulation of honeydew and sooty mould.
In simple terms:
Early detection → good coverage → contact with nymphs → physical action → disruption of honeydew protection.
How should Soptech be applied?
Because Soptech acts by contact, one of the most important factors is achieving adequate wetting of the vegetation.
In the pear psylla applications shown in the video, high spray volumes are used, around 1,000 litres/ha, with higher volumes potentially required depending on canopy development and orchard conditions.
When used alone, the field application described in the video uses approximately 1–1.25 litres of Soptech per 1,000 litres of water, always taking into account the product label and the specific conditions of application.
Soptech can also be used as part of programmes in combination with other pest management products, provided compatibility has been checked beforehand and all technical and legal requirements are followed.
Key points during application
1. Achieve good coverage.
The product needs to come into contact with the pest.
2. Act during the early stages of infestation.
Avoid waiting until psylla populations are already high.
3. Monitor honeydew production.
Honeydew is one of the clearest indicators of psylla activity.
4. Adapt spray volume to the crop.
Canopy structure and density influence the ability of the spray to reach the areas where nymphs are located.
A tool for different soft-bodied insects
Although this article focuses on pear psylla, Soptech is not limited to this pest.
Its contact mechanism and cleaning properties make it suitable for strategies targeting different soft-bodied insects, including:
- Pear psylla
- Aphids
- Whiteflies
- Scale insects
- Other insects associated with honeydew production
This makes Soptech a versatile tool that can be incorporated into crop protection programmes according to the specific pest and crop situation.
Soptech as part of an integrated pest management strategy
Modern pest management increasingly requires strategies that combine different tools and modes of action.
In this context, Soptech can provide a physical and cleaning action that complements other crop protection strategies.
Its contact mechanism is particularly interesting because it does not rely exclusively on a specific biochemical target within the insect. Instead, it acts physically on the insect’s protective outer structure.
At the same time, its ability to act on honeydew addresses an important part of the problem associated with sap-sucking pests.
Soptech can therefore be integrated into crop management programmes adapted to the specific requirements of each crop and pest situation.
Soptech: more than an agricultural cleaner
Honeydew is one of the most visible signs of activity from several sap-sucking pests.
In pear orchards, psylla can produce significant amounts of honeydew, affecting plant surfaces and favouring the development of sooty mould.
Soptech addresses both elements of the problem:
On the insect
Contact action that disrupts its protective outer structure and promotes dehydration.
On honeydew
Cleaning action that breaks down and disperses deposits present on plant surfaces.
On the crop
Removing residues helps maintain cleaner plant surfaces and reduce the consequences associated with honeydew and sooty mould accumulation.
Conclusion
Pear psylla (Cacopsylla pyri) requires a management strategy that takes into account both the insect itself and the consequences of its activity on the crop.
Honeydew production by the nymphs is one of the main problems associated with this pest and can favour the development of sooty mould, affecting fruit appearance and commercial quality.
Soptech provides a different approach based on physical contact action and cleaning activity.
Its formulation based on long-chain fatty alcohols allows it to act on the protective outer structures of certain soft-bodied insects while also helping to break down residues such as honeydew and sooty mould.
The key to achieving good results is to act early and achieve adequate plant coverage, allowing the product to come into contact with the nymphs.
