Spinetoram Methoxyfenozide Synergy Rice Stem Borer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pesticides used in rice cultivation often require high concentrations to achieve effective pest control, and there is a continuous need for new pesticides and methods to manage pest populations effectively, as pests can cause significant agricultural losses worldwide.
Innovation Solution
A synergistic pesticidal composition comprising spinetoram and methoxyfenozide, applied in specific weight ratios, provides superior pest control at lower combined concentrations, effectively controlling a wide range of pests including lepidoptera, arthropods, and nematodes, by contacting rice with a formulation that includes a synergistically effective amount of spinetoram and methoxyfenozide, often in combination with inert carriers and additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of single pesticides are used, then effective pest control is achieved, but environmental safety deteriorates and pest resistance increases
Solution Approach 1:
The patent combines spinetoram and methoxyfenozide into a synergistic pesticidal composition. The combination achieves superior pest control at lower concentrations compared to individual pesticides, thereby maintaining effectiveness while reducing environmental harm and resistance risk.
Solution Approach 2:
The invention creates a composite pesticidal formulation containing spinetoram and methoxyfenozide in specific ratios. This composite composition leverages the complementary modes of action of both pesticides to achieve enhanced efficacy at reduced dosages, addressing both control effectiveness and environmental safety.
2Reliability
If high concentrations of single pesticides are used, then effective pest control is achieved, but the risk of pest resistance increases
Solution Approach 1:
By merging spinetoram and methoxyfenozide into a single formulation, the patent creates a multi-mode-of-action pesticide that achieves effective control at lower concentrations. This reduces the selective pressure that drives resistance development while maintaining reliable pest control.
Solution Approach 2:
The invention changes the concentration parameter by using lower doses of active ingredients through synergistic combination. This parameter change reduces the environmental load and selective pressure on pest populations, thereby mitigating resistance risk while preserving control effectiveness.
3Object-affected harmful factors
If lower concentrations of pesticides are used, then environmental safety is improved, but pest control effectiveness deteriorates
Solution Approach 1:
The patent develops a composite pesticidal material combining spinetoram and methoxyfenozide that exhibits synergistic activity. This composite enables effective pest control at lower concentrations than would be required for individual pesticides, thus improving environmental safety without sacrificing control reliability.
Solution Approach 2:
The invention utilizes parameter changes in the form of synergistic interaction between two pesticides, which amplifies the biological effect at lower concentrations. This allows the system to achieve the same level of pest control effectiveness with reduced chemical input, thereby improving environmental safety.
4Ease of operation
If individual pesticides are used separately, then application flexibility is maintained, but the synergistic effect is lost
Solution Approach 1:
The patent merges spinetoram and methoxyfenozide into a single ready-to-use pesticidal composition. This maintains application flexibility as a single product while capturing the synergistic effect that enhances pest control effectiveness beyond what either pesticide could achieve alone.

AI summary
A method of protecting rice from infestation and attack by pests comprises contacting rice with a pesticidal composition that comprises a synergistically effective amount of spinetoram and methoxyfenozide. The pesticidal composition comprises methoxyfenozide in an amount of at least three parts by weight per one part by weight of spinetoram.
