Entomopathogenic Nematode Wetting Composition for Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biopesticides lack a flexible, user-friendly, multipurpose solution that effectively targets specific pests while being safe for users and the environment, leading to low adoption compared to chemical pesticides.
Innovation Solution
A pest control kit comprising entomopathogenic nematodes and a wetting composition with specific surfactants and solvents, such as dipropylene glycol methyl ether and aryl ether phosphate ester potassium salt, enhances nematode viability, dispersal, and pest mortality, tailored for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional wetting agents are used with entomopathogenic nematodes, then wetting capacity is improved, but nematode viability and efficacy are reduced
Solution Approach 1:
The patent changes the chemical composition parameters of the wetting agent by specifying precise concentrations of surfactants (0.01-10% v/v), solvents (0.01-25% v/v), and co-surfactants (0.01-10% v/v). This parameter optimization ensures compatibility with entomopathogenic nematodes while maintaining effective wetting capacity, resolving the contradiction between wetting performance and nematode viability.
Solution Approach 2:
The invention uses a composite wetting agent formulation combining multiple components: surfactants, solvents, and co-surfactants in specific proportions. This composite approach creates a synergistic effect where each component contributes to different aspects of performance, achieving both good wetting capacity and high nematode viability simultaneously.
2Object-affected harmful factors
If biopesticides are used instead of chemical pesticides, then safety and environmental friendliness are improved, but adoption is reduced due to lack of user-friendly flexibility
Solution Approach 1:
The patent creates a universal pest control kit that can be applied to multiple pest types and various application methods (soil drench, foliar spray, irrigation system). The standardized formulation with optimized wetting agents provides consistent performance across different applications, making biopesticides as flexible and easy to use as chemical pesticides while maintaining safety benefits.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kit ensures at least 90% nematode survival and 90% pest mortality for up to 72 hours, with improved dispersal, addressing the limitations of conventional wetting agents that reduce nematode efficacy.
Implementation Method 1
the wetting composition comprising one or more surfactants
Implementation Method 2
improved wetting capacity
Implementation Method 3
the solvent comprises a glycol ether. Preferably the glycol ether is dipropylene glycol methyl ether

AI summary
A pest control kit is provided to aid the control of a population of immature larval stages or pupal insects. The pest control kit comprises an amount of an entomopathogenic nematode and a wetting agent composition, the wetting agent composition comprising: a solvent; and a surfactant. The pest control kit aims to provide a naturally occurring entomopathogenic nematode for biological control of immature larval insects which can act as pests to plants, whether these be for professional plant protection including agricultural, forestry and horticultural or for home garden use. The new pest control product of the present invention aims to prove safe and sustainable protection for turf and plants all year round.
