Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing use of synthetic pesticides in agriculture is facing challenges such as toxicity, environmental damage, and the lack of effective, environmentally friendly alternatives for combating plant pathogens, with biopesticides being less effective and costly to develop.

Innovation Solution

The use of an extract from rocket plants, specifically from the Eruca sativa and related species, to stimulate plant defenses against pathogens by applying the extract through foliar spray, irrigation, or seed treatment, which enhances the plant's natural defense mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synthetic pesticides are used to combat plant pathogens, then pathogen control effectiveness is improved, but environmental damage and toxicity increase

Engineering Contradiction:

Improvepathogen control effectivenessVSAvoidenvironmental damage and toxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by using plant-derived extracts (rocket plant, neem, garlic, etc.) instead of synthetic chemicals. This substitution maintains pathogen control effectiveness while reducing environmental toxicity and harm, directly resolving the contradiction between effectiveness and environmental damage

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs naturally decomposable organic extracts from plants as temporary protective agents. These natural extracts provide sufficient pathogen control during the critical growth period and then decompose harmlessly, unlike persistent synthetic pesticides that accumulate and cause long-term environmental damage

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Object-affected harmful factors

If biopesticides are used as environmentally friendly alternatives, then environmental harm is reduced, but effectiveness and production cost are worsened

Engineering Contradiction:

Improveenvironmental harmVSAvoidpathogen control effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent combines multiple biopesticidal extracts (rocket plant, neem, garlic, rosemary, thyme, oregano, sage, lavender, mint, lemon balm, and essential oils) into a synergistic formulation. This combination enhances the overall pathogen control effectiveness beyond what individual biopesticides achieve alone, while maintaining environmental friendliness

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite biopesticide formulation integrating diverse plant extracts and essential oils with complementary modes of action. This composite approach addresses the effectiveness limitation of single-component biopesticides while preserving their environmental benefits

Inventive Principle:

Principle #40Composite materials

3Object-affected harmful factors

If biopesticides are developed as alternatives to synthetic pesticides, then environmental friendliness is improved, but production cost and development complexity increase

Engineering Contradiction:

Improveenvironmental friendlinessVSAvoidproduction cost and development complexity

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent utilizes plants that can be cultivated by farmers themselves or locally sourced, reducing dependency on expensive industrial biopesticide production. The formulation uses readily available natural materials that minimize complex manufacturing processes and approval costs associated with synthetic pesticides

Inventive Principle:

Principle #25Self-service

AI summary

The method for stimulating the defenses of a plant or tree against an infection of bacterium or fungus comprises the application on the plant or tree of an aqueous extract from at least leaves of a Rocket plant. The application on the plant or tree is achieved by foliar spray. The extract is obtained by grinding the Rocket plants in an aqueous medium, filtering the ground material obtained and recovering the liquid extract of Rocket plants obtained after filtering.
