Gelatin

Gelatin, when used as an active ingredient in plant protection, belongs to a group of natural animal-derived proteins that act through physical rather than chemical pathways.

The core mechanism involves the formation of a thin, elastic film on the surface of plant tissues and the bodies of pests upon the evaporation of the carrier liquid.

This film creates a mechanical barrier that effectively seals the respiratory spiracles of insects and mites, causing mortality via suffocation.

Beyond the respiratory block, the adhesive nature of the dried gelatin restricts the movement and feeding capabilities of the pests.

Because it is a biodegradable protein, it poses minimal risk to the environment, soil health, or beneficial organisms present in the agro-ecosystem.

Gelatin-based preparations are primarily utilized as contact-acting insecticides and acaricides against small, soft-bodied pests.

Common targets include various aphid species that cause significant damage to vegetable and ornamental crops during the growing season.

It is also frequently employed to manage spider mite populations, particularly in greenhouse environments where non-toxic alternatives are preferred.

The treatment is effective against whiteflies by hindering their mobility and limiting the spread of infestations across the canopy.

• Spider mites
• Whiteflies
• Thrips

Application rates are determined by the specific formulation's concentration and the density of the pest population on the crop.

Thorough coverage of all plant surfaces, including the underside of leaves, is essential to ensure maximum contact with the target organisms.

Applications should be timed to coincide with dry weather conditions to ensure the gelatin film dries quickly and adheres properly to the plant surface.

Repeat treatments are typically scheduled every 7 to 10 days to target nymphs or newly emerged individuals that were missed during the first application.

Environmental temperature at the time of application should be monitored to ensure optimal polymer formation of the gelatinous barrier.

High humidity and rainfall are the primary limitations, as they prevent the necessary drying process required for the gelatin film to act effectively.

The product lacks systemic activity, meaning it does not translocate within the plant and cannot protect new leaves emerging after treatment.

Compatibility with other agrochemicals must be assessed in tank mixes to ensure the physical stability of the gelatin solution is maintained.

Due to its biological nature, the solution is susceptible to microbial degradation, requiring immediate use after preparation.

The efficiency of the product depends heavily on the precision of spray application; any uncovered areas remain vulnerable to pest colonization.
