Fungicidal Composition for Soybean Rust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fungicides are inadequate for controlling rust diseases in soybean crops, particularly caused by Phakopsora pachyrhizi, leading to significant yield losses due to insufficient activity and crop tolerance issues.
Innovation Solution
A novel fungicidal composition combining a compound of formula I, where R1 is difluoromethyl or trifluoromethyl and X is chloro, fluoro, or bromo, with other fungicides such as strobilurins, azoles, morpholines, and anilinopyrimidines, or insecticides, to enhance effectiveness against phytopathogenic fungi.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customary fungicides are used for controlling rust in soybeans, then application is simple and cost is low, but activity against Phakopsora pachyrhizi is insufficient leading to yield losses
Solution Approach 1:
The patent combines compound (A) with at least one compound from group (B) to create synergistic fungicidal compositions. This merging of different active ingredients with distinct modes of action achieves reliable control of Phakopsora pachyrhizi while preventing yield losses, resolving the contradiction between fungicide activity and productivity protection.
Solution Approach 2:
The invention uses composite fungicidal formulations containing compound (A) from formula I combined with compounds from group (B) including strobilurins, azoles, morpholines, anilinopyrimidines, and other fungicides. These composite materials provide enhanced and reliable activity against Phakopsora pachyrhizi compared to single-ingredient fungicides, thereby protecting soybean yield.
2Reliability
If compound (A) is combined with multiple fungicides from group (B), then activity against broader spectrum of fungi is improved, but composition complexity increases
Solution Approach 1:
The patent segments the fungicidal composition into distinct functional groups: compound (A) from formula I and compounds from group (B) including strobilurins, azoles, morpholines, anilinopyrimidines, and other specific fungicides. This segmentation allows each component to target different phytopathogenic fungi with specific modes of action, achieving broad-spectrum reliability while maintaining structured composition complexity that is manageable for formulation and application.
