Flupyrimin Pyridylidene Compound for Rice Pest Control and Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rice cultivation in Asia faces significant yield gaps due to persistent insect infestations by Lepidoptera and Hemiptera pests, with existing pest control methods being inefficient and environmentally impactful, necessitating a solution that enhances plant health and grain yield while effectively controlling pests.
Innovation Solution
The use of flupyrimin, a pyridylidene compound, is applied to plants, plant parts, or propagation materials to confer a phytotonic effect, improving root and shoot growth, and controlling insect infestations, including resistant pest species, thereby enhancing crop yield and plant health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional chemical insecticides are used to control rice pests, then pest infestation is reduced, but plant health deteriorates and yield gap remains large
Solution Approach 1:
The patent changes the chemical parameter by using flupyrimin, a pyridylidene compound with unique biological properties, instead of conventional insecticides. This compound provides both insecticidal activity against Lepidoptera and Hemiptera pests and phytotonic effects that improve plant health and increase grain yield, thereby resolving the contradiction between pest control and productivity improvement
Solution Approach 2:
Flupyrimin serves multiple functions simultaneously: it acts as an insecticide against multiple pest types (Lepidoptera and Hemiptera), provides phytotonic effects to enhance plant growth, and extends pest control duration. This multi-functionality allows a single application to address both pest control and yield improvement, eliminating the need for separate treatments that would harm plant health
2Object-affected harmful factors
If multiple chemical applications are made for systematic pest control, then pest infestation is controlled, but environmental impact increases and plant health suffers
Solution Approach 1:
The patent applies flupyrimin in a preliminary manner that provides long-lasting pest control activity. The compound's unique biological properties enable it to establish effective pest control and phytotonic effects early, reducing the need for subsequent chemical applications and thereby minimizing environmental impact while maintaining plant health
Solution Approach 2:
By changing the chemical parameter to flupyrimin, the patent achieves superior safety toward pollinators and reduced environmental impact compared to conventional insecticides. The compound's specific chemical structure provides outstanding potency against resistant pests while being safer for the environment and non-target organisms
3Object-affected harmful factors
If conventional insecticides are applied, then pest control is achieved, but phytotonic effect is insufficient and plant growth is limited
Solution Approach 1:
Flupyrimin is a universal compound that simultaneously provides insecticidal activity against multiple pest types and phytotonic effects that enhance plant growth. This multi-functionality allows the single application to both control pests and improve plant strength, eliminating the trade-off between pest control and plant growth that plagues conventional insecticide use
Solution Approach 2:
The patent changes the biological parameter by using flupyrimin, which has unique biological properties that include outstanding potency against resistant pests together with superior safety toward pollinators and enhanced phytotonic effects. This parameter change enables simultaneous achievement of pest control and plant growth promotion
