Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a pressing need for alternative and more effective strategies to stimulate plant growth and biologically control phytopathogens such as bacteria, fungi, and nematodes, while minimizing environmental impact and avoiding resistance to chemical treatments.
Innovation Solution
The use of Bacillus methylotrophicus strain XT1, deposited as CECT8661, which produces spores, biofilms, and various enzymes and compounds that enhance plant growth and inhibit pathogens, combined with localized irrigation systems for application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical treatments are used to control phytopathogens and stimulate plant growth, then plant protection and growth stimulation are achieved, but environmental contamination and development of resistance occur
Solution Approach 1:
The patent converts the harmful effect of chemical pesticides into a beneficial biological control system by using beneficial microorganisms (Bacillus subtilis, Pseudomonas fluorescens, Trichoderma harzianum) that produce antibiotics and compete with phytopathogens, thereby protecting plants without chemical contamination
Solution Approach 2:
The patent introduces intermediary biological agents (beneficial bacteria and fungi) that mediate between the plant and phytopathogens, providing protection through biological mechanisms such as antibiotic production, competition for nutrients, and induction of plant resistance rather than direct chemical action
2Reliability
If chemical pesticides are applied to control phytopathogens, then disease incidence is reduced, but pollinating insects and animal health are negatively affected
Solution Approach 1:
The patent transforms the harmful impact on beneficial organisms into a beneficial outcome by using selective biological control agents that specifically target phytopathogens while leaving pollinating insects and other beneficial organisms unaffected, thereby protecting both plants and ecosystem health
3Ease of operation
If conventional irrigation systems are used for applying bacterial treatments, then application is simple, but treatment effectiveness is reduced due to dilution and non-targeted distribution
Solution Approach 1:
The patent applies bacterial treatments locally at the root zone through subsurface irrigation systems, concentrating the beneficial microorganisms where they are most needed (in the rhizosphere) rather than distributing them widely through conventional overhead irrigation, thereby enhancing treatment effectiveness while maintaining ease of operation
Solution Approach 2:
The patent uses hydraulic systems (subsurface irrigation) to deliver bacterial treatments directly to the root zone through underground pipes and emitters, leveraging fluid pressure and flow control to achieve targeted application without the dilution and waste associated with conventional spray systems
