Methylobacterium Compositions for Corn Rootworm Damage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling corn rootworm (CRW) damage to corn plants are inadequate, leading to significant plant damage and yield loss.
Innovation Solution
The use of CRW-active Methylobacterium bacteria, specifically isolates such as ISO01, ISO02, ISO03, and ISO04, applied as compositions to corn plants or seeds, either as solid substances with adherent bacteria or emulsions, to inhibit CRW growth and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to control corn rootworm, then application simplicity is maintained, but control effectiveness is insufficient leading to significant plant damage and yield loss
Solution Approach 1:
The patent uses Methylobacterium bacteria as a biological intermediary agent to control corn rootworm. The bacteria are applied to corn seeds or plants and provide protective action against CRW damage through biological mechanisms, achieving superior control effectiveness compared to conventional methods while maintaining practical application simplicity
Solution Approach 2:
The patent changes the parameter of control agent type from conventional chemical insecticides to biological agents (Methylobacterium bacteria). This parameter change enables enhanced control effectiveness (reducing CRW damage by up to 75%) while the bacteria can be applied using standard agricultural application methods, keeping the operational complexity manageable
2Reliability
If higher doses of conventional insecticides are applied, then control effectiveness improves, but environmental harm and non-target effects increase
Solution Approach 1:
The patent converts the use of beneficial biological agents (Methylobacterium bacteria) into a solution that controls harmful corn rootworm while avoiding the environmental harm associated with conventional insecticides. The bacteria naturally inhibit CRW growth and development without causing harm to non-target organisms or the environment
Solution Approach 2:
The Methylobacterium bacteria serve as a biological intermediary that provides CRW control through natural mechanisms rather than toxic chemical action. This intermediary approach achieves effective control (up to 75% damage reduction) while eliminating the environmental contamination and non-target effects associated with high-dose conventional insecticide applications
