Evaluation of the pesticide embedded paint for poultry facilities

1. Only 0.3% of the sprayed pesticide goes directly into the target pest, while 99.7% enters the surface or groundwater and may contaminate them.
2. Sprayed pesticide often forms aerosol which can cause respiratory problems to poultry upon inhaling, and
3. Sprayed pesticide can be readily degraded even at ambient conditions (e.g., room temperature, rain, natural sunlight, etc.).

Hence, there is a need for developing a new pest-control solution.

Objectives

General: To develop pest-repellent paint for poultry facilities and assess its long-term performance.

Specifics:

• To synthesize and characterize pest-repellent paint by utilizing all plant-derived materials;
• optimize the paint’s pest-repellency by modulating various experimental parameters; conduct comprehensive and comparative repellency tests by using three independent methods that involve area preference test, mortality test, and cage test; evaluate long-term efficacy; and
• test the feasibility in a real application.

Important details of the materials and methods:

During the course of the project, researchers developed pest-repellent paint by copolymerizing epoxidized soybean oil (ESO), permethrin, capsaicin and citric acid.

Various coating parameters included compositions, thickness and crosslinking densities. Pest-repellency tests were conducted, and the paint’s long-term efficacy of pest-repellency was evaluated for 12 months.

Results

Results showed that
