The study, funded by the US Department of Agriculture, lasted four years and eventually developed a small piece of garlic that could protect up to 0.4 hectares of farmland from pests. This garlic flavor is worth less than 1 cent per piece and can be formulated into a solution to infiltrate crops. About 70% of the 140 million people in Bangladesh depend directly on agriculture for their livelihood. The country needs to import millions of dollars of pesticides each year. . Experts say continued use of chemical pesticides has led to a decline in soil fertility and has also cost the farmers in the world's poorest countries a heavy cost.
The study was conducted in the northern city of Mehsing, Bangladesh. Bahadurmeya, director of the Integrated Pest Control Laboratory here, said: "This garlic-flavored tablet is a bio-insecticide that will lead to a revolution in the elimination of chemical pesticides."
He said: "The germination rate of seeds soaked in garlic-flavored solvents is over 95%, and the germination rate of seeds without such treatment is only 56% to 60%. It makes healthy seedlings free of disease and can also avoid insecticides. The contamination of the soil by the agent."
Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
