Solution Overview

Problem

Current methods for controlling invertebrate pests in turf, such as white grubs and chinch bugs, are often ineffective due to pest resistance and the need for high pesticide doses, posing challenges in maintaining turf health and aesthetics, especially in golf courses and athletic fields.

Innovation Solution

A mixture of alpha-cypermethrin and dinotefuran, applied in a weight ratio of 500:1 to 1:500, is used to combat invertebrate pests in turf, leveraging a synergistic effect to reduce pesticide amounts while maintaining insecticidal activity, and can be applied through various formulations including emulsifiable concentrates, suspensions, and granules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high doses of single pesticides are used to control resistant pests, then pest control effectiveness is improved, but harm to turf and surrounding plants increases

Engineering Contradiction:

Improvepest control effectivenessVSAvoidharm to turf and plants

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines two different insecticides with distinct modes of action (alpha-cypermethrin as a pyrethroid and dinotefuran as a neonicotinoid) into a single formulation. This synergistic combination allows for effective pest control at lower total doses, reducing harm to non-target plants while maintaining reliability against resistant pest populations

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite pesticidal formulation containing both alpha-cypermethrin and dinotefuran in specific weight ratios (1:1 to 1:10 or 10:1 to 1:1). This composite approach leverages the complementary properties of both active ingredients to achieve superior control effectiveness with reduced individual component doses, thereby minimizing phytotoxicity

Inventive Principle:

Principle #40Composite materials

2Reliability

If high pesticide doses are applied to overcome resistance, then insecticidal activity is maintained, but pesticide usage quantity increases

Engineering Contradiction:

Improveinsecticidal activityVSAvoidpesticide usage amount

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

By merging two insecticides with different modes of action into a single application, the formulation achieves synergistic effects that enhance overall insecticidal activity. This allows the use of lower total pesticide quantities while maintaining or improving control effectiveness against resistant pest populations

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention changes the chemical composition parameters of the pesticidal formulation by incorporating both pyrethroid and neonicotinoid classes in specific ratios. This parameter modification enables reduced application rates while preserving insecticidal activity, directly addressing the contradiction between maintaining effectiveness and reducing quantity

Inventive Principle:

Principle #35Parameter changes

Function Achieved in This Case

The mixture effectively controls a wide range of invertebrate pests in turf with reduced pesticide usage, minimizing harm to the turf and surrounding plants, and is suitable for various application methods including soil treatment and foliar application.

Implementation Method 1

the combination of alpha-cypermethrin and dinotefuran has a synergistic effect on invertebrate pests prevalent in turf, which means that the total amount of pesticide can be reduced while preserving excellent insecticidal activity

Methodology Applied

Scientific EffectSynergistic effect:

Implementation Method 2

Pyrethroids obstruct the normal function of an insect's sodium channels resulting in the loss of function of the nerve cell, shutdown of the insect nervous system and ultimately death

Methodology Applied

Scientific EffectSodium channel obstruction:

Implementation Method 3

Its mode of action involves the disruption of the insect's nervous system by inhibiting nicotinic acetylcholine receptors and has been found useful in controlling pyrethroid resistant pests

Methodology Applied

Scientific EffectReceptor inhibition:

AI summary

The present invention relates to methods and uses for combating or controlling invertebrate pests in turf, which comprises applying a mixture comprising alpha-cypermethrin and dinotefuran to the turf area, the invertebrate pests or their food supply, habitat or breeding grounds. The most common invertebrate pests in turf are certain worms, e.g. Armyworm, ants, e.g. fire ants, bugs and in particular white grubs, which are larvae of different kinds of insects, mainly of bugs. They usually live in the soil and damage the turf grass plants by feeding on their roots. The turf pests can be efficiently combated or controlled by the methods and uses of the invention.
