A choice for obtaining clean vegetables and with quality
Biopesticide formulated with the nematode Heterorhabditis bacteriophora, which has a complex mechanism of action due to its symbiotic relationship with bacteria belonging to the genus Photorhabdus pathogenic to different insects. It is used in organic and conventional production systems.
Active ingredient: Infective juveniles (IJ) of Heterorhabditis bacteriophora Strain HC1
Presentation: Transparent polyethylene bags with a sheet of polyether-polyurethane sponge having 5 million IJ in water.

The nematode, in its Infective Juvenile (IJ) phase, penetrates into the insect through its natural openings (mouth, anus and spiracles). In the case of Heterorhabditis, it also penetrates directly through the soft tissue between the segments, releasing the bacterium inside the insects. Meanwhile, the bacterium, once inside the insect, reproduces rapidly, degrading the tissues of the insect which dies by a generalized infection. In that moment, the nematode finds the adequate conditions for feeding and breeding on the tissues previously degraded by the bacterium.
Within the insect corps, many generations of nematodes can be produced, but when food becomes scarce, the IJ leave the place and move along the soil looking for new insects to parasitize, and they are able to establish in the soil.
The entomopathogenic nematodes are very effective in pest management, because they have combined characteristics of parasitoids and microbial pathogens. They coincide with parasitoids in being motile and having chemoreceptors (used to orientate themselves to find the insect), and with pathogens in being highly virulent, killing the host insect quickly (48-72 hours) and in being reproduced in culture media, having a high reproductive potential.
They are environmentally safe either for plants, vertebrates or others, and can be used in the management of domestic pests.
- At transfer, they should not be exposed to sunlight or other heat sources, nematodes are also sensitive to sunlight UV.
- They must be applied during the coolest hours of the day, preferably at sunset.
- Use good quality water (potable) to prepare the solution to be applied with a backpack sprayer.
- They are compatible with other control agents such as Beauveria bassiana, Bacillus thuringiensis and Lecanicillium lecanii. It has been shown that they can be applied with FitomaS® (bio-nutrient manufactured in Cuba), with excellent results with their joint use in corn, sweet potato, cabbage and ornamental plants.
- Nematodes should be used as soon as possible after arrival at the farm, they must be alive to act and can die in a prolonged storage (exhaustion of internal reserves).
