25% Tebuconazole EW Small Trial R&D Report

1. Formulation difficulties and problems

Tebuconazole as a highly effective broad-spectrum systemic fungicide is well known by the majority of farmers, because it has a broader bactericidal spectrum and more thorough control of diseases and is widely used, but 25% Tebuconazole EW water emulsion is a more difficult formulation of water emulsions, the thermal storage stability is very poor, are thermal storage of broken emulsion delamination and other serious problems.

2. Formulation

3.Testing the indicators of the preparation

1.Hot storage 14 days, the stability of qualified, placed at room temperature for 1 year, no delamination oil precipitation water phenomenon. Take qualified samples to continue to refine the experiment, and measure the indicators.

2.Cold storage stability qualified.

3.Ph=6.38, in a reasonable range and so on.

4.Preparation dilution stability

Diluted 100 times with standard hard water, red and blue light is obvious, put into the water bath for 24 hours on no floating oil, no precipitation.

4.Summary

From the experiment can be seen 3% bifenthrin (benzene oil) +3% acetamiprid ME, additives 14% solvent 14%, lower cost, low temperature stability is poor, but can be restored to room temperature, more suitable for the cost of high requirements of the customer; additives 16% solvent 16%, physical stability is good, the transparent interval is wide, suitable for product quality requirements of high customers; compromise considerations can be used additives 15% solvent 15%. The compromise is to use 15% solvent 15% additives.
