HEFEI scarpe nike air max scontate , Sept. 12 (Xinhua) -- Chinese scientists have developed a smart pesticide that, once in the soil, is controllable and recyclable.
A team led by Wu Zhengyan, professor with the Technical Biology Institute nike air max 2018 scontate , under Hefei Institute of Physical Science, Chinese Academy of Sciences, used diatomite, iron magnesium oxide and chitosan to make a compound that can be activated by changes to pH levels in the soil.
"The release of the pesticide mixed with the additive can be easily adjusted by pH changes. The additive wraps up the drug and acts like a gatekeeper. It opens the gate and dissolves in acidic conditions nike air max scontate ," Wu said.
He said the research showed that a single-season crop only needed the pesticide spray once. During the growth of the plant, growers simply spray a weak-acid agent to activate and control the pesticide's effect. Conventional farming needs several rounds of pesticide spray.
The report on the research was published in the latest issue of the Chemical Engineering Journal, an international research journal.
Wu said China's agriculture relied heavily on the use of pesticide, which was estimated at over 1 million tonnes a year. However Uomo Nike Air Vapormax 2.0 Flyknit Scarpe Dark Grigie Scontate , less than 40 percent of such pesticide actually had an effect on crops and the rest simply washed off, contaminating soil and water.
He said the additive had magnetism, which made it feasible to recover the pesticide from soil and water.
"The recycling effect during our tests shows 30 percent of pesticide residue can be recovered," Wu said.
According to the research Nike Air Max Plus TN Ultra Scarpe Nere Scontate , sponsored by the National Natural Science Foundation and the Chinese Academy of Sciences, the nano-pesticide showed a high adhesion ability on weak surfaces and pest epidermis.
Wu said that it was still too early to put the results into commercial use as the cost of nano-material and recycling was too high for farmers.
"We take it as a stage one success and will continue to upgrade to make it more efficient and economical," he said.

COPENHAGEN, Sept. 12 (Xinhua) -- Terminal 2 of Copenhagen Airport in the Danish capital city was closed on Tuesday morning as police were investigating an "odd size luggage," the airport announced on its Twitter account.
It did not tell how long the airport would be closed and how many flights would be affected.
Copenhagen Airport is the busiest airport in Scandinavia, which served more than 29 million passengers in 2016 with its two terminals.
Security in European countries has been on high alert after a series of attacks hit populated areas such as airports and train stations in recent years.
Explosions at Brussels airport and metro systems on March 22 Nike Air VaporMax 97 Argento Bullet Scarpe Scontate , 2016 killed 32 people, and blasts struck Ataturk airport in Istanbul on June 28 in the same year, leaving 42 people dead and 239 wounded.
