Solution Overview

Problem

Current methods for controlling plant diseases are not effective enough, leading to significant crop losses, and there is a need for a more potent solution.

Innovation Solution

A composition comprising the Bacillus strain APM-1 and one or more succinate dehydrogenase inhibitors, such as penflufen, sedaxane, fluopyram, and boscalid, is used to control plant diseases, applied to seeds, vegetative propagation organs, or directly to plants to enhance disease control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional plant disease control methods are used, then crop production is maintained, but significant crop losses occur due to insufficient disease control effectiveness

Engineering Contradiction:
Improvedisease control effectivenessVSAvoidcrop production
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines Bacillus strain APM-1 with succinate dehydrogenase inhibitors (such as penflufen, sedaxane, fluopyram, fluxapyroxad, or boscalid) to create a composite composition that achieves superior disease control effectiveness compared to single agents, thereby resolving the contradiction between reliability and productivity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention uses a composite formulation integrating biological control agents (Bacillus strain APM-1) with chemical succinate dehydrogenase inhibitors to create a synergistic effect that enhances disease control reliability while maintaining crop production

Inventive Principle:
Principle #40Composite materials

2Reliability

If more potent disease control materials are sought, then control effectiveness is improved, but the complexity of formulation and application increases

Engineering Contradiction:
Improvedisease control effectivenessVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent specifies precise parameter ranges for the composition including Bacillus strain APM-1 at 10^4 to 10^14 cfu/kg and succinate dehydrogenase inhibitor at 0.000001 to 15 g/kg, which optimizes the formulation to achieve effective disease control while managing formulation complexity through defined parameters
