Solution Overview

Problem

There is currently no effective and environmentally friendly method to treat citrus greening disease caused by Candidatus Liberibacter asiaticus, which affects citrus trees' ability to absorb nutrients, leading to reduced fruit production and significant economic losses.

Innovation Solution

Introduce an oversupply of native algae, including unicellular and flagellated strains, into the soil of affected citrus groves to enhance nutrient availability and stimulate natural antibiotic and peptide production, thereby resisting the bacteria responsible for citrus greening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional pesticides are used to treat citrus greening, then treatment effectiveness may be improved, but environmental damage occurs

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidenvironmental damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies this principle by using beneficial native microorganisms (algae, bacteria, fungi) to counteract the harmful effects of Candidatus Liberibacter asiaticus. Instead of using harmful pesticides, the invention introduces beneficial microbes that produce antibiotics and peptides to fight the pathogen, converting the approach from harmful to beneficial while maintaining treatment effectiveness

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent uses native microorganisms as intermediaries between the citrus trees and the pathogen. These microorganisms act as mediators by producing antibiotics and peptides that directly combat Candidatus Liberibacter asiaticus, providing a natural buffer that protects trees without introducing harmful chemicals into the environment

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If citrus trees are treated with conventional methods, then disease suppression may be achieved, but nutrient absorption remains impaired

Engineering Contradiction:
Improvedisease suppressionVSAvoidfruit production
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies self-service by introducing native microorganisms that independently produce antibiotics, peptides, and nutrients within the tree's root system. These microorganisms autonomously fight the pathogen and provide nutrients, enabling the tree to recover its natural nutrient absorption capabilities without external intervention, thereby restoring fruit production

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention uses a composite approach by combining multiple types of native microorganisms (algae, bacteria, fungi) that work synergistically. The algae provide nutrients and oxygen, bacteria produce antibiotics, and fungi enhance nutrient absorption, creating a composite biological system that simultaneously addresses disease suppression and nutrient absorption

Inventive Principle:
Principle #40Composite materials

AI summary

Some embodiments of the disclosure are directed to systems and methods to treat citrus greening. In some embodiments, one or more samples are taken from a location where citrus greening occurs or may occur. In some embodiments, native microorganisms are isolated and propagated. In some embodiments, the microorganisms include algae. In some embodiments, propagated native algae is returned to an area affected by citrus greening. In some embodiments, the returned propagated native algae is distributed to a concentration of 10 times or more of the original native algae concentration. In some embodiments, the distributed algae increase natural antibiotics and nutrients in the soil resulting in prevention of citrus greening.
