Biological Control Agent and Insecticide Composition for Crop Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synthetic insecticides and fungicides are non-specific, toxic, and lead to resistance in pathogens, posing environmental and health concerns, while biological control agents have limited effectiveness and are not entirely satisfactory in controlling severe infections.
Innovation Solution
A composition comprising specific biological control agents like Bacillus pumilus, Bacillus subtilis AQ713, and Bacillus subtilis AQ30002 in synergistically effective amounts with insecticides such as Spirotetramat and Spiromesifen, applied simultaneously or sequentially to enhance control of insects, mites, nematodes, and phytopathogens, reducing overall damage and resistance formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic insecticides and fungicides are used, then pest control effectiveness is improved, but environmental and health safety deteriorates due to toxicity and non-biodegradability
Solution Approach 1:
The patent combines biological control agents (Bacillus subtilis, Bacillus pumilus) with synthetic insecticides and fungicides into a single composition, allowing the biological agents to reduce toxicity and environmental harm while the synthetic components maintain pest control effectiveness
Solution Approach 2:
Biological control agents serve as intermediaries that enhance the effectiveness of reduced amounts of synthetic pesticides, enabling lower application rates while maintaining control efficacy and reducing harmful residues
2Reliability
If synthetic insecticides are repeatedly applied, then initial pest control is effective, but resistance development in pathogens occurs
Solution Approach 1:
The patent changes the mode of action parameter by introducing biological control agents with different mechanisms (parasitism, predation, competition) alongside synthetic pesticides, preventing resistance development through multi-target attack
Solution Approach 2:
The composition uses composite action of biological control agents and synthetic pesticides, where the biological agents provide sustained control and resistance management while synthetic components deliver immediate knockdown effect
3Object-affected harmful factors
If biological control agents are used alone, then environmental safety is improved, but control effectiveness against severe infections deteriorates
Solution Approach 1:
The biological control agents in the composition perform multiple functions: they provide base-level pest suppression, enhance the activity of synthetic pesticides, and reduce the required dosage of chemical components, thereby achieving both environmental safety and effective control
4Loss of substance
If application rates of active compounds are reduced, then residues in crops are decreased, but control effectiveness may deteriorate
Solution Approach 1:
Biological control agents in the composition provide self-amplifying effects where they colonize the plant surface and continuously suppress pests over time, maintaining control effectiveness even at reduced application rates compared to synthetic pesticides alone
