Application of fatty acid methyl ester (biodiesel) in herbicides

The waste oil contains various fatty acid fats and can be used as a pesticide auxiliary agent in the field of herbicides . According to the characteristics of the waste oil, the research and development personnel made it into a pesticide synergist for the atrazine herbicide used in corn fields.
Firstly, the efficacy test was carried out in the laboratory. The results showed that the synergist can significantly enhance the effect of atrazine on the control of the weeds of the scorpion and the drought, and the addition of auxiliaries at different dosages. The efficacy of no adjuvant treatment increased by 33% to 40%. Immediately afterwards, the research team commissioned the Shanghai Academy of Agricultural Sciences to conduct field bioactivity tests. The area of ​​the corn test field was about 2.5 mu. The results of the 20-day investigation showed that the synergist can significantly improve the efficacy of atrazine on weed dry gold. Post-drug observation showed that corn growth was normal in each drug treatment area.
After the initial victory, Daejeon's real test was carried out in the Xuanhua area of ​​Hebei Province. The synergist was applied to the atrazine herbicide. The dosage was reduced by about one-third compared with the normal use. The visual results showed that the effect was similar to the original dosage. The agricultural costs of farmers can be greatly reduced.
