2) spraying process crop and 2h after process of spraying equally is exposed to rainfall is 10mm, reaches the crop of 1h and compare, result shows that the two is consistent to the control efficiency of barley leaf blight.Just because of systemic activity and the evaporate active of ZEN 90160, thus after dispenser, active component can effectively be reallocated and fully transmit, and therefore ZEN 90160 has better therapeutic activity than commercial Fluoxastrobin and oxime bacterium ester.
Be mainly used in preventing and treating foliage disease as leaf blight, leaf rust, glume blight, brown spot, powdery mildew etc., compared with existing strobilurin series bactericidal agent, have stronger result for the treatment of to leaf blight, net blotch and moire disease.
Crops are in process of growth, and also can face disease except facing insect pest, some germs also can aggravate the insect pest of plant conversely to ozone deplation.Common solution can only reach the object of desinsection or diseases prevention, and its property of medicine is single, cannot integrated control, causes medication repeatedly.It is composite that ethiprole and ZEN 90160 are carried out science by us, to reaching the object of sterilization and disinsection simultaneously, reduces the incidence of plant pest, Promoting plant growth, reaches the object of volume increase, can reduce dispenser cost simultaneously, saving resource, reaches the double effect controlled of effect of holding concurrently.
At present, ethiprole and ZEN 90160 composite and be applied in and have no report both at home and abroad.
