Chicoric Acid Phytosanitary Composition for Aphid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insecticides are toxic to humans and the environment, and their widespread use leads to the development of resistant insect populations, necessitating the need for effective, non-toxic compounds with high insecticidal power against aphids at low doses.
Innovation Solution
Chicoric acid, a compound with proven insecticidal properties, is used in phytosanitary applications to repel or eliminate aphids and other plant pests, formulated in concentrations ranging from 0.06 to 5 mM, offering a repellent or toxic effect depending on the dose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insecticides are used to control aphids, then insecticidal efficacy is improved, but toxicity to humans and environment worsens
Solution Approach 1:
The patent changes the chemical parameter from synthetic insecticides to chicoric acid, a natural phenolic compound. This parameter change maintains insecticidal efficacy through the acid's toxic and repellent effects on aphids while eliminating the harmful toxicity associated with conventional synthetic insecticides to humans and the environment.
2Reliability
If conventional insecticides are used repeatedly, then initial control effect is improved, but development of resistant insect populations worsens
Solution Approach 1:
The patent changes the chemical parameter from conventional insecticides to chicoric acid, which operates through different mechanisms (toxic and repellent effects) that aphids have not developed resistance against. This parameter change provides sustained control effectiveness without the resistance problem that plagues repeated use of conventional insecticides.
3Power
If high doses of insecticides are used to ensure effectiveness, then insecticidal power is improved, but harm to human health and environment worsens
Solution Approach 1:
The patent changes the chemical parameter to chicoric acid, which provides high insecticidal power through its natural toxic and repellent properties. The key advantage is that this high power is achieved without the harmful effects on human health and environment that characterize high-dose conventional insecticide applications.
4Object-affected harmful factors
If natural origin insecticides are used to reduce toxicity, then safety is improved, but insecticidal efficacy may worsen
Solution Approach 1:
The patent selects a specific natural compound parameter - chicoric acid - that overcomes the typical limitation of natural insecticides. This phenolic acid from the Asteraceae family provides both the safety of natural origin (low toxicity) and superior insecticidal efficacy through its dual toxic and repellent actions on aphids.
