Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved methods to control Tipula spp. insect larvae, particularly leatherjackets, in turfgrass, as existing chemical and biopesticide approaches face challenges in efficacy and environmental impact.
Innovation Solution
A combination method using chlorantraniliprole and entomopathogenic nematodes, applied at reduced rates, to enhance control of Tipula spp. larvae in turfgrass, including sequential applications to optimize efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical insecticides like chlorantraniliprole are used to control Tipula spp. larvae, then pest control efficacy is improved, but environmental loading and harm to beneficial insects increase
Solution Approach 1:
The patent combines chlorantraniliprole with entomopathogenic nematodes in a single application treatment. This merging allows the chemical insecticide to provide immediate pest control while the biopesticide components target specific pest stages and reduce overall environmental loading through biological mechanisms.
Solution Approach 2:
The invention creates a composite pest control system combining chemical and biological agents. The chlorantraniliprole formulation is combined with entomopathogenic nematodes to create a multi-mode of action treatment that maintains efficacy while reducing reliance on chemical alone.
2Object-affected harmful factors
If entomopathogenic nematodes are applied alone to control Tipula spp. larvae, then environmental safety is improved, but control efficacy and shelf-life are reduced
Solution Approach 1:
The patent merges entomopathogenic nematodes with chlorantraniliprole to enhance the overall control efficacy. While the nematodes provide environmental safety through biological mechanisms, the chemical component boosts the effectiveness against Tipula spp. larvae, creating a synergistic effect.
3Reliability
If full rate of entomopathogenic nematodes is applied, then pest control coverage is improved, but application cost and complexity increase
Solution Approach 1:
The patent applies entomopathogenic nematodes at a reduced rate (50-75% of the full rate typically applied alone) when combined with chlorantraniliprole. This partial action approach maintains adequate pest control coverage while reducing application complexity and cost, as the chemical component compensates for the reduced biological agent dosage.
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 combination significantly reduces leatherjacket populations and maintains turf quality, demonstrating enhanced pest control with reduced chemical usage.
Implementation Method 1
the effectiveness of chlorantraniliprole in the control of Tipula spp. insect larvae in turf is enhanced when it is co-applied with entomopathogenic nematodes
