Solution Overview

Problem

Existing insecticidal compositions lack effective enhancement of insecticide activity, and there is a need for improved adjuvants that can enhance the bioperformance and efficacy of insecticides without causing undue phototoxic effects on host plants.

Innovation Solution

The use of an organic phosphonate adjuvant, specifically compounds with the formula (I) and their alkoxylated derivatives, which are combined with insecticides to enhance their activity, particularly against chewing and sucking pests, and are formulated to be compatible with various insecticide modes of action and application methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing insecticidal compositions are used, then basic insecticide activity is provided, but insecticide activity enhancement is insufficient

Engineering Contradiction:

Improveinsecticide activityVSAvoidinsecticide efficacy

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent introduces organic phosphonate compounds as intermediary adjuvants that mediate between the insecticide and the target pest. These phosphonates enhance insecticide activity by improving penetration, retention, and biological effectiveness without being the primary active ingredient themselves, thus resolving the contradiction between basic activity and enhanced efficacy.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates composite insecticidal compositions by combining insecticides with organic phosphonate adjuvants. This composite approach allows the synergistic interaction between the insecticide and phosphonate to enhance overall insecticidal activity and efficacy, addressing the insufficiency of using insecticides alone.

Inventive Principle:

Principle #40Composite materials

2Productivity

If adjuvants are added to enhance insecticide activity, then insecticide efficacy is improved, but phototoxic effects on host plants may increase

Engineering Contradiction:

Improveinsecticide efficacyVSAvoidphototoxic effects on plants

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent carefully selects and optimizes the chemical parameters of the organic phosphonate adjuvants, specifically choosing compounds with alkyl groups containing 4-20 carbon atoms. This parameter optimization ensures enhanced insecticide efficacy while maintaining safety by preventing undue phototoxic effects on host plants.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention applies the adjuvant principle locally to the insecticidal composition rather than universally to all agricultural chemicals. By specifically formulating phosphonate-adjuvanted insecticide compositions, the enhancement is targeted where needed (insecticide activity) without unnecessarily exposing plants to potential phototoxicity from broad-spectrum adjuvant use.

Inventive Principle:

Principle #3Local quality
