Three-Component Pesticidal Composition Synergy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current combinations of pesticidal active ingredients are not entirely satisfactory in terms of pathogenic control, phytotoxicity, and environmental and worker exposure, particularly when pathogens become resistant, necessitating improved methods for controlling or preventing pathogenic and pest damage in plant propagation materials.
Innovation Solution
A combination of at least three active ingredient components: an azole fungicide, a phenylamide fungicide, and a strobilurin or phenylpyrrole fungicide, such as thiabendazole, mefenoxam, and azoxystrobin, which are applied to plant propagation materials to provide synergistic protection against pathogens and pests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional single or dual active ingredient combinations are used, then application rates can be kept simple, but pathogenic control effectiveness is insufficient and resistance develops
Solution Approach 1:
The patent combines three distinct fungicide classes (azole, phenylamide, and strobilurin or phenylpyrrole) into a single pesticidal composition, creating a multi-component system that addresses pathogenic control through synergistic interactions while managing the complexity of the combination
2Reliability
If higher application rates are used to overcome resistance, then pathogenic control is improved, but environmental and worker exposure increases
Solution Approach 1:
The patent changes the chemical composition parameters by introducing a three-component fungicide system with specific synergistic relationships, allowing effective pathogenic control at reduced application rates compared to conventional single or dual ingredient treatments
3Duration of action of moving object
If conventional fungicide combinations are used, then short-term control is achieved, but duration of action is limited
Solution Approach 1:
The patent creates a composite pesticidal formulation integrating three different fungicide classes (azole, phenylamide, and strobilurin or phenylpyrrole) that work synergistically together, providing extended duration of protection through the complementary mechanisms of action of each component

AI summary
A method of controlling or preventing pathogenic damage or pest damage in a plant propagation material, a plant, parts of a plant and/or plant organs that grow at a later point in time, which comprises applying on the plant, part of the plant, or surroundings thereof, a pesticidal combination comprising, for example, at least three active ingredient components optionally together with one or more customary formulation auxiliaries, wherein component (I) is one or more of an -azole fungicide, component (II) is one or more of a phenylamide fungicide, component (III) is one or more of a strobilurin fungicide and/or one or more of a phenylpyrrole fungicide, in any desired sequence or simultaneously.
