Effect of Chimeiling on Controling Scab in Wheat

Chimeiling, a new kind of mixture for controlling wheat scab, was invented in 1993 and came into use in recent years. Here we had carried out a series of experiments to test its scab controlling capacity and to investigate its action mechanism. The main conclusions were as follows: Compared with carbendazin, Chimeiling had a better scab controlling effect, longer effective application period and wider varietal adaptability ; Besides its scab controlling function, Chimeiling could also stimulate fertilization that led to an increase in number of grains per spike; scab controlling mechanism of Chimeiling included two aspects, to increase the wheat plant resistance and to inhibit the fungus growth.
