pH-Adjusted Bacillus Pest Control Agent for Direct Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bacillus bacteria-based pest control agents degrade during distribution and storage when pre-diluted, leading to unstable control effects due to decomposition, and users face difficulties in accurately diluting powdered forms for use.
Innovation Solution
A stabilized harmful organism control agent is developed by adjusting the pH of a Bacillus bacteria-water mixture to a range of 4 to 10, incorporating a pH adjusting agent and optional surfactants and reduced starch sugar, allowing pre-dilution to a spray concentration range for improved storage stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bacillus bacteria are pre-diluted to spray concentration range, then ease of operation is improved (users can spray directly without dilution), but storage stability deteriorates (decomposition progresses during distribution and storage)
Solution Approach 1:
The patent applies parameter changes by adjusting the pH of the pre-diluted Bacillus bacteria solution to a specific range (pH 3-9, preferably pH 4-8) to simultaneously achieve both direct spray readiness and improved storage stability. This chemical parameter modification prevents decomposition while maintaining the convenient pre-diluted state.
2Reliability
If Bacillus bacteria are distributed in concentrated state, then storage stability is improved, but ease of operation deteriorates (users must accurately dilute before use)
Solution Approach 1:
The patent resolves this contradiction by pre-diluting the Bacillus bacteria to spray concentration and then adjusting the pH to a stable range (pH 3-9). This allows the product to be distributed in ready-to-use concentration while maintaining storage stability through pH control, eliminating the need for users to perform accurate dilution.
3Ease of operation
If Bacillus bacteria are pre-diluted without pH adjustment, then ease of operation is improved, but manufacturing precision deteriorates (control effect becomes unstable due to decomposition)
Solution Approach 1:
The patent applies parameter changes by adjusting the pH to a specific range (pH 3-9) in the pre-diluted solution, which stabilizes the Bacillus bacteria and prevents decomposition. This ensures consistent control effect while maintaining the convenience of direct spray application without further dilution.
