We did a test to compare,we grew some grapes in garden,and use one kind of  pesticides to kill the insects,but did not use the sterilization  pesticides.The grapes grew up slowly and they are not of uniform size.At the same time,the grapes grew with white rot and mildew.The grapes are infected with the bacteria can not continue to grow up.And the grape which next to it will also be infected with the bacteria subsequently.It will affect the overall quality.

 The vineyard's  grapes just use the  alternating current outdoor pest control lamp,did'n use any any sterilization device and pesticides. The grapes didn't have any germs infection.They grew healthily and they are in the uniform size.We can really do the  organic, natural, no pesticides, no insect pest!!!!
