Isoxazoline Pesticide Composition for Low-Dose Resistant Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pesticides face limitations in effectively controlling pests due to resistance development, leading to the need for safer alternatives that provide excellent control at low concentrations to minimize soil contamination and secondary harm to humans and livestock.
Innovation Solution
A novel isoxazoline derivative compound represented by Formula 1, its stereoisomers, hydrates, or salts, which are incorporated into a pesticide composition to control pests, particularly those of the order Thrips and Lepidoptera, with specific structures and functional groups enhancing pesticidal activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If highly toxic and high-concentration pesticides are used to control resistant pests, then pest control effectiveness is improved, but soil contamination and secondary damage to humans and livestock increase
Solution Approach 1:
The patent develops novel isoxazoline derivative compounds with modified chemical structures (Formula 1 with specific R1-R4 substituents) to achieve high pesticidal activity at low concentrations, changing the concentration parameter from high to low while maintaining or improving control effectiveness
Solution Approach 2:
The patent creates composite pesticide formulations combining isoxazoline derivative compounds with specific adjuvants and carriers (including surfactants, solvents, and solid diluents) to enhance efficacy while reducing the need for high concentrations of toxic active ingredients
2Object-affected harmful factors
If new pesticide substances are developed to be safer for humans and livestock, then safety is improved, but control effectiveness against resistant pests may be reduced
Solution Approach 1:
The patent modifies molecular parameters of the isoxazoline core structure (with specific R1-R4 groups including halogens, alkyls, cycloalkyls, and heterocyclic groups) to optimize the balance between safety and efficacy, achieving compounds that are both safer and highly effective
Solution Approach 2:
The patent introduces specific functional groups and substituent patterns at different positions of the isoxazoline molecule to create localized variations in toxicity and efficacy, allowing different parts of the molecule to contribute differently to safety and control effectiveness
