A highly sensitive reusable electrochemical sensor for detecting the pesticide carbosulfan in food products has been developed by scientists at Tomsk Polytechnic University (TPU) in collaboration with their colleagues.
According to the researchers, the sensor is ten times more sensitive to this life-threatening substance compared to existing analogs. The results of the study were published in the scientific journal Microchemical Journal.
Carbosulfan is a chemical used in agriculture to combat insect pests, such as the Colorado potato beetle. While highly effective, it is toxic to humans.
Researchers from TPU's School of Natural Resources Engineering and the Research School of Chemical and Biomedical Technologies, in collaboration with the Institute of Strength Physics and Materials Science of the Siberian Branch of the Russian Academy of Sciences (SB RAS) and Charles University in the Czech Republic, have developed a highly sensitive sensor to detect carbosulfan residues in food.
Poster Comment:
From Dr Horse's gardening notes. White flies and aphids eliminated with Mg, Sulfur, Mo and Boron foliar sprays.
Mg + S + Mo + B + Molasses can kill remaining insects (feeding on leaves) like stink bug, Colorado potato beetle. 24 hours to total kill.
No need for pesticide if the plants are suffering from a nutritional deficiency.
Soak seeds in Mn, Co, Cu, Zinc and Boron. Soak for 24 hours to give them a boost at germination.
