Solution Overview

Problem

Existing herbicides are inadequate for effectively controlling undesirable vegetation in desired crops without harming the desirable vegetation.

Innovation Solution

Compositions comprising a pyridine carboxylate herbicide and a protoporphyrinogen oxidase (PROTOX) inhibitor herbicide, applied in specific weight ratios, are used to control undesirable vegetation in crops.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing herbicides are used to control undesirable vegetation, then some level of vegetation control is achieved, but the effectiveness is inadequate and desirable vegetation may be harmed

Engineering Contradiction:

Improveherbicide effectivenessVSAvoidharm to desirable vegetation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines two different herbicide chemistries (pyridine carboxylate and PROTOX inhibitor) into a single composition to achieve synergistic effects. This merging of different active ingredients provides superior weed control while reducing harm to desirable vegetation compared to using either herbicide alone.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite herbicide formulation containing both pyridine carboxylate and PROTOX inhibitor at specific ratios. This composite material leverages the complementary modes of action of both herbicides to achieve reliable weed control with improved safety for desirable crops.

Inventive Principle:

Principle #40Composite materials

2Productivity

If higher concentrations of single herbicide are used to improve control effectiveness, then vegetation control improves, but harm to desirable vegetation increases

Engineering Contradiction:

Improvevegetation control effectivenessVSAvoidharm to desirable vegetation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Instead of increasing the concentration of a single herbicide, the patent merges two different herbicides at optimized ratios. This combination achieves high productivity in weed control while the specific ratio formulation prevents excessive harm to desirable vegetation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention optimizes the concentration ratio parameters of the two herbicides (pyridine carboxylate to PROTOX inhibitor from 1:2000 to 600:1 by weight). By adjusting these parameter ratios, the formulation achieves maximum effectiveness while minimizing harm to desirable plants.

Inventive Principle:
