Influences of various agricultural chemicals mixed with thiamine on thiamine activity in plants

Abstract

The influences of various agricultural chemicals mixed with thiamine on thiamine activity in plants were tested.
The results obtained were as follows:
1. The thiamine foliar sprays mixed with acidic Gramin spreader are desirable, but those with alkaline Bordeaux mixture are undesirable for the yield of crops.
2. In the case of mixture with acidic chemicals such as Gramin spreader, improved Rino spreader or nicotine sulphate, the stability of thiamine is comparatively high, but that in the by mixture with alkaline chemicals such as Bordeaux mixture orlime sulfur is comparatively low.
3. The thiamine stability in the mixture with fertilizers for foliar sprays such as urea or Yogen is comparatively high.
